问题
I have this nav drawer which was working perfectly fine.
Refactoring my code I removed all onOptionsItemSelecteds
in activities and made all activities inherit from a base activity which extends AppComplatActivity
and implements all the necessary methods.
After this clicking on hamburger icon does not work any more even though I have syncstate
() and every thing.
Any clues why this is not working?
One of the activities:
public class MainActivity extends BaseActivity implements SearchFilterFragment.OnFragmentInteractionListener {
NavigationView navigationView;
DrawerLayout drawerLayout;
private Tracker mTracker;
@Override
protected void onResume() {
super.onResume();
drawerLayout.openDrawer(GravityCompat.START);
}
@Override
protected void onPostResume() {
super.onPostResume();
mTracker.setScreenName("MainActivity" + "-----");
mTracker.send(new HitBuilders.ScreenViewBuilder().build());
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerLayout.openDrawer(GravityCompat.START);
navigationView = (NavigationView) findViewById(R.id.navigation_view_primary);
navigationView.setNavigationItemSelectedListener(new NavigationDrawerListener(this));
setupToolbar();
Haftdong application = (Haftdong) getApplication();
mTracker = application.getDefaultTracker();
}
private void setupToolbar() {
// Show menu icon
final ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);// will make the icon clickable and add the < at the left of the icon.
DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();//for hamburger icon
}
@Override
public void onFragmentInteraction(Uri uri) {
}
}
BaseActivity:
public class BaseActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_base, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

You're using the four-parameter constructor for ActionBarDrawerToggle
, which means you'll have to call the toggle's onOptionsItemSelected()
method in MainActivity
's onOptionsItemSelected()
override in order to open/close the drawer.
For example:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if(mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
If you happen to be providing your own Toolbar
– e.g., as the support ActionBar
(though it's not necessary to set it as such) – then you can instead pass that Toolbar
as the third argument in the ActionBarDrawerToggle
constructor call. For example:
Toolbar toolbar = findViewById(R.id.toolbar);
ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout,
toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
The drawer opening/closing will then be handled by ActionBarDrawerToggle
internally, and you won't need to call through to the toggle in onOptionsItemSelected()
.
The setDisplayHomeAsUpEnabled()
call is also unnecessary for this setup, which is handy if you don't want to set the Toolbar
as the ActionBar
.
