Navigation Drawer Icon (ic_drawer) not showing

android, android-actionbar, icons, navigation-drawer

Solution

I know it is quite late to answer this but this would help someone atleast.

You should probably add these lines of code to show that navigation icon.

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    // Sync the toggle state after onRestoreInstanceState has occurred.
    mDrawerToggle.syncState();
}

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

Problem

I am implementing a navigation drawer for my app. Now it works perfectly except for one small glitch. When I set the Navigation Drawer Icon (ic_drawer) to replace the regular "HomeAsUp" caret icon, I still get the arrow. The Nav Drawer icon does not show. I have implemented every method that was on the android developers website. But it doesn't seem to work. Below is my code: ``` DrawerLayout mDrawerLayout; FrameLayout leftDrawer, rightDrawer, contentFrame; ActionBarDrawerToggle mDrawerToggle; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_home); initializeViews(); } private void initializeViews() { // TODO Auto-generated method stub mDrawerLayout = (DrawerLayout) findViewById(R.id.mDrawerLayout); mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, R.string.drawer_open_content_desc, R.string.drawer_close_content_desc); getActionBar().setHomeButtonEnabled(true); getActionBar().setDisplayHomeAsUpEnabled(true); mDrawerLayout.setDrawerListener(mDrawerToggle); leftDrawer = (FrameLayout) findViewById(R.id.drawerLeft_frame); rightDrawer = (FrameLayout) findViewById(R.id.drawerRight_frame); contentFrame = (FrameLayout) findViewById(R.id.content_frame); } @Override protected void onPostCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onPostCreate(savedInstanceState); mDrawerToggle.syncState(); } @Override public void onConfigurationChanged(Configuration newConfig) { // TODO Auto-generated method stub super.onConfigurationChanged(newConfig); mDrawerToggle.onConfigurationChanged(newConfig); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.home, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // TODO Auto-generated method stub if (mDrawerToggle.onOptionsItemSelected(item)) { return true; } return super.onOptionsItemSelected(item); } ```
