I'm creating an app that has a navigation drawer. First it is working but when i edit the layout_gravity of my toolbar to end, i got an error
java.lang.IllegalArgumentException: No drawer view found with gravity LEFT
MainActivity
I dont know what's wrong in my code but i change only the layout_gravity to end.
public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private CharSequence mTitle;
private CharSequence mDrawerTitle;
private ActionBarDrawerToggle mDrawerToggle;
private Toolbar topToolBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/****************************************************************************************

mTitle = mDrawerTitle = " ";
topToolBar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(topToolBar);
topToolBar.setLogo(R.drawable.logo);
topToolBar.setLogoDescription(" ");
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
List<DrawerItem> drawerItems = new ArrayList<DrawerItem>();
drawerItems.add(new DrawerItem("Home"));
drawerItems.add(new DrawerItem("Student"));
drawerItems.add(new DrawerItem("Teacher"));
mDrawerList.setAdapter(new DrawerAdapter(this, drawerItems));
mDrawerToggle = new ActionBarDrawerToggle(MainActivity.this, mDrawerLayout, R.string.drawer_open, R.string.drawer_close) {
/**

}
/**

public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);

}
};
// Set the drawer toggle as the DrawerListener
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.setDrawerIndicatorEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
});
}
private void selectItem(int position){
switch(position) {

case 2:

}
mDrawerList.setItemChecked(position, true);
mDrawerLayout.closeDrawer(mDrawerList);
