Changing Navigation drawer hamburger icon

Question

I am trying to change hamburger menu icon for NavigationView but I am unable to do so.

Here is what I have tried so far

I have a base activity where nav drawer setup is done. Here is relevant piece of code

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    super.setContentView(R.layout.activity_base_nav);
    setSupportActionBar(toolbar);
    setupDrawer();
}

private void setupDrawer() {
    mDrawerLayout.setDrawerListener(this);

    mDrawerToggle = new ActionBarDrawerToggle(this,
            mDrawerLayout,
            R.string.open,
            R.string.close);

    mDrawerToggle = new ActionBarDrawerToggle(mContext,
            mDrawerLayout,
            R.string.open,
            R.string.close);

    mDrawerLayout.setDrawerListener(mDrawerToggle);

    if (getSupportActionBar() != null) {
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(false);
        mDrawerToggle.setDrawerIndicatorEnabled(false);
       mDrawerToggle.setHomeAsUpIndicator(R.drawable.ic_share_48pt_2x);
    }
    mDrawerToggle.syncState();

    mNavigationView.setNavigationItemSelectedListener(
            menuItem -> {
                mMenuItem = menuItem.getItemId();
                mDrawerUtil.onNavMenuItemClicked(mMenuItem);
                mDrawerLayout.closeDrawers();
                return true;
            });
}

@Override 
public void setContentView(int layoutResID) {
    getLayoutInflater().inflate(layoutResID, mContainer);
}


@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    mDrawerToggle.syncState();
}

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

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (mDrawerToggle.onOptionsItemSelected(item)) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

However it doesn't seem to be working for me. I have also tried calling setDrawerIndicatorEnabled(false) and setHomeAsUpIndicator(R.drawable.ic_share_48pt_2x) on SupportActionBar but that also doesn't work.

Answer 1

The following code works nicely for me,

protected void onCreate(Bundle savedInstanceState) {
    ...
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(false);
    toggle.setDrawerIndicatorEnabled(false);
    toggle.setHomeAsUpIndicator(R.drawable.ic_custom_drawer_icon);
    ...
}

I also had to add a toolbar navigation click listener to listen for click events on the custom drawer icon

protected void onCreate(Bundle savedInstanceState) {
    ...
    toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
            if (drawer.isDrawerOpen(GravityCompat.START)) {
                drawer.closeDrawer(GravityCompat.START);
            } else {
                drawer.openDrawer(GravityCompat.START);
            }
        }
    });
    ...
}

Finally, I can update the icon dynamically as

toggle.setHomeAsUpIndicator(R.drawable.ic_new_icon);

Just use this :

toolbar.post(new Runnable() {
            @Override
            public void run() {
                Drawable d = ResourcesCompat.getDrawable(getResources(), R.mipmap.ic_launcher, null);
                toolbar.setNavigationIcon(d);
            }
        });

You dont need to handle setToolbarNavigationClickListener which is in accepted answer.

Have you try to look at the documentation ? http://developer.android.com/training/implementing-navigation/nav-drawer.html

I've found this piece of code in it :

mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
                R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) {

            /** Called when a drawer has settled in a completely closed state.*/
            public void onDrawerClosed(View view) {
                super.onDrawerClosed(view);
                getActionBar().setTitle(mTitle);
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
                getActionBar().setTitle(mDrawerTitle);
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
             }
        };

Here's what works for me:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    setSupportActionBar(toolbar)

    val toggle = ActionBarDrawerToggle(
            this, drawer_layout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close)
    //toggle.isDrawerSlideAnimationEnabled = false
    toggle.isDrawerIndicatorEnabled = false
    toggle.setToolbarNavigationClickListener {
        if (drawer_layout.isDrawerOpen(GravityCompat.START))
            drawer_layout.closeDrawer(GravityCompat.START)
        else
            drawer_layout.openDrawer(GravityCompat.START)
    }
    toggle.setHomeAsUpIndicator(AppCompatResources.getDrawable(this, R.drawable.ic_android_black_24dp))
    drawer_layout.addDrawerListener(toggle)
    toggle.syncState()
    nav_view.setNavigationItemSelectedListener(this)
}

override fun onBackPressed() {
    if (drawer_layout.isDrawerOpen(GravityCompat.START)) {
        drawer_layout.closeDrawer(GravityCompat.START)
    } else {
        super.onBackPressed()
    }
}

override fun onNavigationItemSelected(item: MenuItem): Boolean {
    when (item.itemId) {
        ...
    }
    drawer_layout.closeDrawer(GravityCompat.START)
    return true
}
