Android sidebar like facebook or firefox [duplicate]

Answer 1

I've created my own solution for this as well, as many stock solutions appeared to not work on older Android version 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
• The menu can be any custom View
• The view above can be any custom View as well
• Supported on old Android versions (tested to work at least on Android 2.2)

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:

I did something like below:

Below is my code for something like facebook side menu bar

1. I put 2 views overlap in a frame layout. The bottom view is the menu, the top view is the content body.
2. And I put the content body into a horizantal scroll view. I also put a view to the left of the content body in the horizantal scroll view. And set the view's background as transparent.
3. Then scroll to content body at begining. So the side menu bar is blocked by the content body.
4. When click a button to show the menu, I scroll the horizantal scroll view to show the transparent placeholder. Then the menu will show up since it is under the transparent placeholder now.

I did not use XML for the interface. I create everything in the below code. I think it should be easy to read and put into your eclipse.

Answer 3

I came up with a solution... I don't know if it is perfect but it is working well.

So what I did was a single FrameLayout with both of the Layouts stacked together and then I just animate the top layout to slide to the right of the screen (just need to call the slideTo or scrollBy. And basically it's that! Quite simple and effective! (the code though is not very pretty :P)

EDIT:

Some code samples.

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#FFF" >

        <include
        android:id="@+id/menu_layout"
            layout="@layout/menu_list"
            android:visibility="invisible"/>

        <include
            android:id="@+id/news_list_parent"
            layout="@layout/main_news_list" 
            />

</FrameLayout>

This is the layout xml, quite simpe. The included .xml are simple LinearLayouts with a heading and a listview.

The "magic" happens in the animation:

protected void applyTransformation(float interpolatedTime, Transformation t) {
    int newOffset;
    if(expanded) {
        newOffset = 0;
        newOffset = (int)(endOffset*(1-interpolatedTime));
    } else {
        newOffset = (int)(endOffset*(interpolatedTime));
    }
    view.scrollTo(-newOffset, 0);
}

The endOffset is the target movement. I set it before I start the animation, and the View I want to animate (in this case is the view with the id=news_list_parent) it is set on the constructor.

But just to understand how that works make a button and its listener would do something like this:

if(viewBeneath.getVisibility() == View.INVISIBLE) {
    viewBeneath.setVisibility(View.Visible);
    viewToSlide.slideTo(-(width-50), 0);
}

And finally override the back button to do the opposite of the button

if(viewBeneath.getVisibility() == View.VISIBLE) {
    viewToSlide.slideTo(0, 0);
    viewBeneath.setVisibility(View.Visible);
}

Read this as pseudo-code =) This is what I did in the beginning, that code is lost :P

You can try out this. Good Example. Check for slider class..
