Android – Clicking hamburger icon on Toolbar does not open Navigation Drawer

androidandroid-toolbarnavigation-drawer

I have a simple android.support.v7.widget.Toolbar and all I am trying to do is to open a NavigationDrawer by pressing the "hamburger" icon in the top left corner. The "hamburger" button is visible, and when I start to pull from the left I see the animation on the button but pressing the button does not open/close the NavigationDrawer as I expect. I have followed the [Google Documentation][1] and still am not able to figure this out. Sorry for any confusion, below is the simplified code I am currently attempting to use:

public class MainActivity extends AppCompatActivity implements
    View.OnClickListener,
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener {



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    setContentView(R.layout.activity_main);


    Toolbar toolbar = (Toolbar) findViewById(R.id.my_toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);



    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.d("NICK", "button button button..................");
        }
    });

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
        NavigationView n = (NavigationView) findViewById(R.id.nav);
        mDrawerLayout.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                Log.d("NICK", "button button button..................");
            }
        });

        //mDrawerLayout.setDrawerListener(mDrawerToggle);
        n.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(MenuItem menuItem) {
                switch (menuItem.getItemId()) {
                    ////.......

                }
                mDrawerLayout.closeDrawers();  // CLOSE DRAWER
                return true;
            }
        });

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    Log.d("NICK","CWECNEWKVNERIPNVIEWNFVIPEWNVIPEWNVPIEWNVPIEWNVPIEWNVPIRWNVPRWVPO");
    switch (item.getItemId()) {
        case android.R.id.home:
            mDrawerLayout.openDrawer(GravityCompat.START);  // OPEN DRAWER
            Log.d("NICK","CWECNEWKVNERIPNVIEWNFVIPEWNVIPEWNVPIEWNVPIEWNVPIEWNVPIRWNVPRWVPO");
            return true;

    }
           return super.onOptionsItemSelected(item);


}

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



@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.drawer, menu);
    return true;
}


}

}

And as it is I do not get any of the log debug statements when running.

This is essentially the issue I have: https://stackoverflow.com/a/26636045/1489990. I've followed this and it just doesn't work.

It is my understanding that setNavigationOnClickListener is called when the hamburger icon is pressed, and this is where I am focusing my efforts is to get the event handled properly because when I press the button I do not get my log statement. Let me know if this idea is incorrect. https://developer.android.com/reference/android/widget/Toolbar.html#setNavigationOnClickListener(android.view.View.OnClickListener)

Best Solution

In your ActivityMain.xml, the toolbar is outside of the DrawerLayout. That's the problem. If you want Toolbar to interact with DrawLayout, Toolbar needs to be a child of DrawerLayout.

To fix the problem, make DrawerLayout the root of your activity. Here's the documentation. The relevant quote is:

To add a navigation drawer, declare your user interface with a DrawerLayout object as the root view of your layout. Inside the DrawerLayout, add one view that contains the main content for the screen (your primary layout when the drawer is hidden) and another view that contains the contents of the navigation drawer.

So basically, structure your ActivityMain.xml to be something like this:

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

    <RelativeLayout ...>

        <android.support.v7.widget.Toolbar .../>

        <!-- Your other content goes here -->

    </RelativeLayout>

    <android.support.design.widget.NavigationView .../>

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

That should take care of the problem.
