问题


I really want to implement this (the side navigation) in an app of my own, does anyone know how Google managed to do this?

They seem to have pulled the current window aside and put in a fly-in navigation of their own.

In fact, there's a way to do this. Even without implementing your own ActionBar.

Just have a look at the hierachyviewer! (Located in the tools directory)

There's the DecorView, and a LinearLayout as a child. This LinearLayout contains both the ActionBar and the other content. So, you can simply apply some FrameLayout.LayoutParams to this LinearLayout and get some space on the left side this way. Then, you can fill this space with your menu-ListView and overlay the other content with a FrameLayout, that, when it's clicked, collapses the menu. So, here's some code:

First, the class for collapsing / expanding (SlideMenu.java):

package your.cool.app;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.graphics.Rect;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.view.Window;
import android.view.animation.TranslateAnimation;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.FrameLayout;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;

public class SlideMenu {
//just a simple adapter
public static class SlideMenuAdapter extends ArrayAdapter<SlideMenu.SlideMenuAdapter.MenuDesc> {
    Activity act;
    SlideMenu.SlideMenuAdapter.MenuDesc[] items;
    class MenuItem {
        public TextView label;
        public ImageView icon;
    }
    static class MenuDesc {
        public int icon;
        public String label;
    }
    public SlideMenuAdapter(Activity act, SlideMenu.SlideMenuAdapter.MenuDesc[] items) {
        super(act, R.id.menu_label, items);
        this.act = act;
        this.items = items;
        }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View rowView = convertView;
        if (rowView == null) {
            LayoutInflater inflater = act.getLayoutInflater();
            rowView = inflater.inflate(R.layout.menu_listitem, null);
            MenuItem viewHolder = new MenuItem();
            viewHolder.label = (TextView) rowView.findViewById(R.id.menu_label);
            viewHolder.icon = (ImageView) rowView.findViewById(R.id.menu_icon);
            rowView.setTag(viewHolder);
        }

        MenuItem holder = (MenuItem) rowView.getTag();
        String s = items[position].label;
        holder.label.setText(s);
        holder.icon.setImageResource(items[position].icon);

        return rowView;
    }
}

private static boolean menuShown = false;
private static View menu;
private static LinearLayout content;
private static FrameLayout parent;
private static int menuSize;
private static int statusHeight = 0;
private Activity act;
SlideMenu(Activity act) {
    this.act = act;
}
//call this in your onCreate() for screen rotation
public void checkEnabled() {
    if(menuShown)
        this.show(false);
}
public void show() {
//get the height of the status bar
    if(statusHeight == 0) {
        Rect rectgle = new Rect();
        Window window = act.getWindow();
        window.getDecorView().getWindowVisibleDisplayFrame(rectgle);
        statusHeight = rectgle.top;
        }
    this.show(true);
}
public void show(boolean animate) {
    menuSize = Functions.dpToPx(250, act);
    content = ((LinearLayout) act.findViewById(android.R.id.content).getParent());
    FrameLayout.LayoutParams parm = (FrameLayout.LayoutParams) content.getLayoutParams();
    parm.setMargins(menuSize, 0, -menuSize, 0);
    content.setLayoutParams(parm);
//animation for smooth slide-out
    TranslateAnimation ta = new TranslateAnimation(-menuSize, 0, 0, 0);
    ta.setDuration(500);
    if(animate)
        content.startAnimation(ta);
    parent = (FrameLayout) content.getParent();
    LayoutInflater inflater = (LayoutInflater) act.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    menu = inflater.inflate(R.layout.menu, null);
    FrameLayout.LayoutParams lays = new FrameLayout.LayoutParams(-1, -1, 3);
    lays.setMargins(0,statusHeight, 0, 0);
    menu.setLayoutParams(lays);
    parent.addView(menu);
    ListView list = (ListView) act.findViewById(R.id.menu_listview);
    list.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            //handle your menu-click
        }
    });
    if(animate)
        menu.startAnimation(ta);
    menu.findViewById(R.id.overlay).setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            SlideMenu.this.hide();
        }
    });
    Functions.enableDisableViewGroup((LinearLayout) parent.findViewById(android.R.id.content).getParent(), false);
    ((ExtendedViewPager) act.findViewById(R.id.viewpager)).setPagingEnabled(false);
    ((ExtendedPagerTabStrip) act.findViewById(R.id.viewpager_tabs)).setNavEnabled(false);
    menuShown = true;
    this.fill();
}
public void fill() {
    ListView list = (ListView) act.findViewById(R.id.menu_listview);
    SlideMenuAdapter.MenuDesc[] items = new SlideMenuAdapter.MenuDesc[5];
    //fill the menu-items here
    SlideMenuAdapter adap = new SlideMenuAdapter(act, items);
    list.setAdapter(adap);
}
public void hide() {
    TranslateAnimation ta = new TranslateAnimation(0, -menuSize, 0, 0);
    ta.setDuration(500);
    menu.startAnimation(ta);
    parent.removeView(menu);

    TranslateAnimation tra = new TranslateAnimation(menuSize, 0, 0, 0);
    tra.setDuration(500);
    content.startAnimation(tra);
    FrameLayout.LayoutParams parm = (FrameLayout.LayoutParams) content.getLayoutParams();
    parm.setMargins(0, 0, 0, 0);
    content.setLayoutParams(parm);
    Functions.enableDisableViewGroup((LinearLayout) parent.findViewById(android.R.id.content).getParent(), true);
    ((ExtendedViewPager) act.findViewById(R.id.viewpager)).setPagingEnabled(true);
    ((ExtendedPagerTabStrip) act.findViewById(R.id.viewpager_tabs)).setNavEnabled(true);
    menuShown = false;
}
}

Some helping methods (for me, in static Functions.java):

    public static int dpToPx(int dp, Context ctx) {
    Resources r = ctx.getResources();
    return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp, r.getDisplayMetrics());
}
//originally: http://stackoverflow.com/questions/5418510/disable-the-touch-events-for-all-the-views
//modified for the needs here
public static void enableDisableViewGroup(ViewGroup viewGroup, boolean enabled) {
    int childCount = viewGroup.getChildCount();
    for (int i = 0; i < childCount; i++) {
        View view = viewGroup.getChildAt(i);
        if(view.isFocusable())
            view.setEnabled(enabled);
        if (view instanceof ViewGroup) {
            enableDisableViewGroup((ViewGroup) view, enabled);
            } else if (view instanceof ListView) {
                if(view.isFocusable())
                    view.setEnabled(enabled);
                ListView listView = (ListView) view;
                int listChildCount = listView.getChildCount();
                for (int j = 0; j < listChildCount; j++) {
                    if(view.isFocusable())
                        listView.getChildAt(j).setEnabled(false);
                    }
                }
        }
    }

Then, the layouts:

Layout of the menu (res/layout/menu.xml)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent" >
    <LinearLayout
        android:orientation="vertical"
        android:layout_height="fill_parent"
        android:layout_width="250dip"
        android:background="@color/darkblack">
        <ListView
            android:id="@+id/menu_listview"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:divider="@color/dividerblack"
            android:dividerHeight="2dip"  />
    </LinearLayout>
    <FrameLayout
        android:id="@+id/overlay"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </FrameLayout>
</LinearLayout>

Layout of the listitems (res/layout/menu_listitem.xml):

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="fill_parent" >
    <ImageView
        android:id="@+id/menu_icon"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_marginRight="5dip"
        android:layout_marginLeft="10dip"
        android:layout_marginTop="10dip"
        android:layout_marginBottom="10dip" />

    <TextView
        android:id="@+id/menu_label"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textColor="@color/white"
        android:textSize="24dp"
        android:layout_marginTop="10dip"
        android:layout_marginBottom="10dip" />
</LinearLayout>

How to use it:

In your onCreate():

private SlideMenu slidemenu;
@Override
public void onCreate(Bundle savedInstanceState) {
    //your onCreate code
    slidemenu = new SlideMenu(this);
    slidemenu.checkEnabled();
}

In the handler for your ActionBar homebutton:

slidemenu.show();

That's it!

And now, a little screenshot of it in action:

As far as I know, it is working. If you experience any problems or my explanations are not clear, please contact me!

EDIT: ExtendedViewPager & ExtendedPagerStrip:

ExtendedViewPager:

package your.cool.app;

//source: http://blog.svpino.com/2011/08/disabling-pagingswiping-on-android.html

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class ExtendedViewPager extends ViewPager {

private boolean enabled;

public ExtendedViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
    this.enabled = true;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onTouchEvent(event);
    }

    return false;
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onInterceptTouchEvent(event);
    }

    return false;
}

public void setPagingEnabled(boolean enabled) {
    this.enabled = enabled;
}
}

ExtendedPagerTabStrip:

package your.cool.app;

//source: http://blog.svpino.com/2011/08/disabling-pagingswiping-on-android.html

import android.content.Context;
import android.support.v4.view.PagerTabStrip;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class ExtendedPagerTabStrip extends PagerTabStrip {

private boolean enabled;

public ExtendedPagerTabStrip(Context context, AttributeSet attrs) {
    super(context, attrs);
    this.enabled = true;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onTouchEvent(event);
    }

    return false;
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return super.onInterceptTouchEvent(event);
    }

    return false;
}

public void setNavEnabled(boolean enabled) {
    this.enabled = enabled;
}
}

I use this SlideMenu for an Activity with a ViewPager with PagerTabStrip for tabs like Talk, Market etc. You can't disable these Views in an easy way, so the two classes above just extend them to stop the onTouch event when disabled.




回答2:


There are several attempts at doing this, however I have yet to find a lib or source code on how to implement it successfully with actionbar accross all api levels. One promising lib is here

https://github.com/jfeinstein10/SlidingMenu

here is a video of the example app.

here is the Google Play app link.

This does work with ActionbarSherlock. You will have to build the SlidingMenu library with ABS to get it working. Works and looks great!




回答3:


Did a roundup of the original implementation and added XML parsing as well as autodetection of a possibly present actionbar, so it works with the native as well as a support action bar such as ActionBarSherlock.

The whole thing is now a library project together with an example app and is described over at Sliding Menu for android Thanks to scirocco for the initial idea and code!




回答4:


If you are using API level greater that 11 you can use a much simpler approach inspired by the answer given by @Scirocco 

// get content parent that is basically the whole 
// app screen (viewed from hierarchy viewer)
final LinearLayout content = 
     (LinearLayout) findViewById(android.R.id.content).getParent();

// make new value animator with range from 0 to 1
final ValueAnimator animator = ValueAnimator.ofFloat(0, 1);
// set custom duration
animator.setDuration(500);
// on update is called for every value in the 
    // given range in time frame defined by the duration
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {

    public void onAnimationUpdate(ValueAnimator animation) {
        // get the current value
        float value = ((Float) (animation.getAnimatedValue())).floatValue();
        // translate by that value, minus means translate left
        content.setTranslationX(-250 * value);
    }
});
// start the animator
animator.start();

// make or inflate custom view for test purposes 
Button textView = new Button(this);
textView.setText("TestButton");
// add it to the frame layout that is the parent of the content on position 0
FrameLayout parent = (FrameLayout) content.getParent();
parent.addView(textView, 0);

The idea here is to use ValueAnimator that transforms and not just animates the main layout with the Action bar, so you can interact with the inflated view you want to use as a sliding panel. You should replace the hardcoded values with something that is of use to your app.

I hope this helps :)

Well currently im working on a project and came across Sliding menu,i googled but gets very disappointed to see that no one has given some piece of code or some hint for how to start making a sliding menu,but every one has given link to some github's projects/libraries to use,I decided to do it myself and finally i have my own Sliding Menu Ready...

I have Spent two days on it

1. on making animations of sliding

2. on making it work with all screen resolutions

Its really easy and simple once you get some idea about Animations, i have read some where,its not sensible to re-invent the Wheel(people who are refering to github source code of sliding menu),but i beleif that you should atleast once try to make your own so you get a idea how it actually works and functions :P

so this is a picture of how my sliding menu will going to work

In find.xml i have included filter.xml initially which is invisible

Now FilterAnimation.java

            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(otherLayoutWidth, otherLayoutHeight);

            params.leftMargin = margin;

            params.rightMargin = -margin; //same margin from right side (negavite) so that our layout won't get shrink

        alphaAnimation.setFillAfter(true);

        otherLayout.startAnimation(alphaAnimation);
    }

}

    }

    private void initializeAnimations()
    {   //Setting GlobolLayoutListener,when layout is completely set this function will get called and we can have our layout onbject with correct width & height,else if you simply try to get width/height of your layout in onCreate it will return 0

                filterAnimation.initializeFilterAnimations(filterLayout);

            }
        });

        final ViewTreeObserver findObserver = findLayout.getViewTreeObserver();

        findObserver.addOnGlobalLayoutListener(new OnGlobalLayoutListener()

        int id = v.getId();

        switch(id)

            filterAnimation.toggleSliding();

            break;

}

Here are the animations res/anim

There you go a complete working and functional Sliding Menu, and you can customized it to meet your requirements,if any one still have some problems setting up,feel free to ask,i feel pleasure to help you out :)




回答6:


I've created my own solution for sliding away the view and revealing a menu underneath, as many other solutions appeared to not work on older Android versions or lacked proper instructions on how to get it to work.

My solution has the following features:

  • Provides support for sliding away a view to reveal a menu that lies underneath it
  • Both the menu and the view above can be any custom View
  • Supported on old Android versions (tested to work at least on Android 2.2)
  • Works with PhoneGap / Cordova projects

The solution uses a custom layout, called SlidingMenuLayout, that you are expected to add 2 views to. The first view you add is the menu, the second is the main view.

The simplest way to add the layout to your existing project is to override your Activity's setContentView() method:

@Override
public void setContentView(View view) {
    SlidingMenuLayout layout = new SlidingMenuLayout(this);
    layout.setLayoutParams(new LinearLayout.LayoutParams(
        ViewGroup.LayoutParams.MATCH_PARENT,
        ViewGroup.LayoutParams.MATCH_PARENT, 
        0.0F));
    layout.addView(new MenuView(this));
    layout.addView(view);
    super.setContentView(layout);
}

In this example, MenuView is the view that will actually show the menu. It is up to you to implement this view.
Finally, you can add a button (typically in the top left corner of your main view), that calls openMenu() or closeMenu() on the layout as appropriate.
The code for SlidingMenuLayout is found on the GitHub project page.

For those of you who uses the SlidingMenu library (https://github.com/jfeinstein10/SlidingMenu) there is a way to jack it in and it seems to work! With help of @Scirocco put this in your onCreate for the activity:

ViewGroup decorView = (ViewGroup) getWindow().getDecorView();
mSlidingMenu = new SlidingMenu(this);
ViewGroup mainContent = (ViewGroup) decorView.getChildAt(0);
decorView.removeView(mainContent);
mSlidingMenu.setContent(mainContent);
decorView.addView(mSlidingMenu);
mMenu = (LinearLayout) View.inflate(this, R.layout.menuview, null);
mSlidingMenu.setMenu(mMenu);
mSlidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN);
mSlidingMenu.setBehindOffsetRes(R.dimen.slidingmenu_offset);

basically what it does is replacing the linearlayout in decor view with the slidingmenu instead.

Notice: Ive only tested it lightly but it seems to work.

}

this is my class extends SlidingPaneLayout. Can slide with actio
