How do I add navigation drawer to my existing code?

Question

I have an app in which I have a navigation panel with menu buttons on which I want to apply navigation drawer, currently it takes up the entire screen,but I want to restrict

Answer 1

This is a good article to follow for adding a navigation drawer: http://developer.android.com/training/implementing-navigation/nav-drawer.html

Your navigation drawer is showing a blank panel, because the drawer view in your activity_main.xml is a ListView (which you haven't set any data to).

You want to make this view your fragment.

Your activity_main.xml file should look like. Make sure to replace the class on the fragment tag to the correct class of your navigation fragment.

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <!-- This fragment container is your the place to put your activities content -->

    <FrameLayout
        android:id="@+id/fragment_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/altercolor2" />

    <!--
    This is your navigation drawer. You can adjust the width here, but it should
    be between 240dp and 320dp
    -->

    <fragment
        android:id="@+id/drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        class="com.yourapp.NavigationPanelFragment" />

</android.support.v4.widget.DrawerLayout>

Your MainActivity should look something like this:

public class MainActivity extends AbsBaseaActivity implements OnBackStackChangedListener {
    public static final int REQUEST_CODE_LIST = 100;

    private Fragment mDrawer;
    private ActionBarDrawerToggle mDrawerToggle;
    private DrawerLayout mDrawerLayout;

    public boolean isNavigationOpen() {
        return mDrawerLayout.isDrawerOpen(mDrawer);
    }

    @SuppressWarnings("deprecation")
    public void setNavigationOpen(final boolean isNavigationOpen) {
        final ImageButton mainButton = (ImageButton) findViewById(R.id.button_main);
        if(isNavigationOpen) {
            mainButton.setBackgroundResource(R.drawable.bg_helios_active);
        } else {
            mainButton.setBackgroundDrawable(null);
        }
    }

        activity.startActivity(intent);
    }

        super.onCreate(savedInstanceState);

        initiateMainActionBar();

        final FragmentManager supportFragmentManager = getSupportFragmentManager();
        supportFragmentManager.addOnBackStackChangedListener(this);


        if (savedInstanceState == null) {
            mActiveFragment = DashboardFragment.getInstanceWithTransition(supportFragmentManager);

    }
}

Notice that the state of the navigation drawer is managed by the drawer layout. The DrawerLayout and the drawer fragment is bound up in the onCreate method.

Refer to the article i mentioned if you run into trouble.

--- EDIT ----

Below is an activity I have used in an app. It shows how to add the drawer toggle (the link I posted also shows this).

You should be able to merge this with your current activity and have a working navigation drawer.

public class SampleActivity extends AbsBaseaActivity {

    private Fragment mDrawer;
    private ActionBarDrawerToggle mDrawerToggle;
    private DrawerLayout mDrawerLayout;

    @Override public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerMenuItems = getResources().getStringArray(R.array.home_menu_drawer_titles);
        mDrawer = (fragment) findViewById(R.id.drawer);

        /* Set up the drawer toggle */
        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_closed) {

            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                getActionBar().setTitle(R.string.activity_title);
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                getActionBar().setTitle(R.string.app_name);
            }
        };

        // Set the drawer toggle as the DrawerListener
        mDrawerLayout.setDrawerListener(mDrawerToggle);

    }

    /**
     * Backward-compatible version of {@link ActionBar#getThemedContext()} that
     * simply returns the {@link android.app.Activity} if <code>getThemedContext</code> is unavailable.
     */
    @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH) private Context getActionBarThemedContextCompat() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
            return getActionBar().getThemedContext();
        } else {
            return this;
        }
    }

    @Override protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        mDrawerToggle.syncState();
        mDrawer.setItemChecked(0, true);
    }

    @Override public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        mDrawerToggle.onConfigurationChanged(newConfig);
    }

    @Override public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case android.R.id.home:
            if (mDrawerLayout.isDrawerOpen(mDrawer)) {
                mDrawerLayout.closeDrawer(mDrawer);
            } else {
                mDrawerLayout.openDrawer(mDrawer);
            }
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

If you are having errors, then post what the errors are.

Answer 2

All the answer above are awesome but I found it little bit difficult to add it in my existing code so I have created a new class which uses animation and LayoutInflater to add view and removes the navigation drawer to the activity you can use it in fragment also.

NavigationDrawer.java

import android.app.Activity;
import android.support.constraint.ConstraintLayout;
import android.util.DisplayMetrics;
import android.view.LayoutInflater;
import android.view.animation.Animation;
import android.view.animation.TranslateAnimation;

import static android.content.Context.LAYOUT_INFLATER_SERVICE;

public class NavigationDrawer {

//State is the visible state
private Boolean state = false, Transition = false;
private ConstraintLayout mainView;
private ConstraintLayout navigationLayout;
private Animation show, hide;

public NavigationDrawer(Activity activity, ConstraintLayout view) {

    this.mainView = view;

    LayoutInflater layoutInflater = (LayoutInflater) 
activity.getSystemService(LAYOUT_INFLATER_SERVICE);
    navigationLayout = (ConstraintLayout) layoutInflater.inflate(R.layout.nav_drawer, 
mainView, false);

    DisplayMetrics displayMetrics = new DisplayMetrics();
    activity.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);

    //Show animation
    show = new TranslateAnimation(-displayMetrics.widthPixels, 0, 0, 0);
    show.setDuration(500);
    show.getFillAfter();
    show.setAnimationListener(new Animation.AnimationListener() {
        @Override
        public void onAnimationStart(Animation animation) {
            Transition = true;
        }

        @Override
        public void onAnimationEnd(Animation animation) {
            Transition = false;
            state = true;
        }

        @Override
        public void onAnimationRepeat(Animation animation) {

        }
    });

    //Hide animation
    hide = new TranslateAnimation(0, -displayMetrics.widthPixels, 0, 0);
    hide.setDuration(500);
    hide.getFillAfter();

    hide.setAnimationListener(new Animation.AnimationListener() {
        @Override
        public void onAnimationStart(Animation animation) {
            Transition = true;
        }

        @Override
        public void onAnimationEnd(Animation animation) {
            Transition = false;
            state = false;
        }

        @Override
        public void onAnimationRepeat(Animation animation) {

        }
    });
}

public void toggle() {
    if (!Transition) {
        if (!state) {
            mainView.addView(navigationLayout);
            navigationLayout.startAnimation(show);
        } else {
            navigationLayout.startAnimation(hide);
            mainView.removeView(navigationLayout);
        }
    }
}
}

To use this class.

NavigationDrawer navigationDrawer = new 
NavigationDrawer(this,user_activity_main_layout);

//To toggle it
navigationDrawer.toggle();

Here user_activity_main_layout is the Id of root ConstrainLayout you can choose whatever you want. This works perfect.

Answer 3

U can get source ode for navigation drawer from the link below

http://hmkcode.com/android-creating-a-navigation-drawer/

copy this to workspace, or open as a new android project from existing source code.

right click on project > properties >java buildpath> add external jar> choose latest V13 support library from android sdks installed and in order and export tick the jar v13

again right click on project > properties >android>choose abs library. [google for library]

U will get error free working project
