The navigation drawer in my app is not closing. I am using activities instead of fragments. When i click on any item in the listview
, it opens other activities as it should but when i go back, the drawer is still open. I have tried using DrawerLayout.closeDrawers();
but it did not work. How do I close the navigation drawer?
Here is my code:
Java
public class MainActivity extends FragmentActivity {
final String[] data ={"Aluminium","Gold","Zinc"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, data);
final DrawerLayout drawer = (DrawerLayout)findViewById(R.id.drawer_layout);
final ListView navList = (ListView) findViewById(R.id.left_drawer);
navList.setAdapter(adapter);
navList.setOnItemClickListener(new AdapterView.OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> parent, View view, final int pos,long id){
switch (pos){
case 0:
Intent i = new Intent(MainActivity.this,Aluminium.class);
startActivity(i);
break;
case 1:
Intent i2 = new Intent(MainActivity.this,Gold.class);
startActivity(i2);
break;
case 2:
Intent i3 = new Intent(MainActivity.this,Zinc.class);
startActivity(i3);
break;
}
}
});
}
}
XML
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:background="#000000"
android:layout_height="match_parent" >
</FrameLayout>
<ListView android:id="@+id/left_drawer"
android:layout_width="220dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="1dp"
android:background="#000000"/>
</android.support.v4.widget.DrawerLayout>
have you tried :
mDrawerLayout.closeDrawer(drawerListView);
You can add this before calling startActivity()
In continuation to others answers and @ Chinmay Dabke question of 'but the drawer closes half then pauses and then closes fully' in one of the comments, here is what you could do:
first as others suggested,
this line is missing. drawer.closeDrawer(navList);
And as far as the pausing of drawer is concerned while closing, you could do something like this. use a Runnable and a Handler like this:
mRunnable = = new Runnable() {
@Override
public void run() {
//say
selectItem(pos); //Implement your switch case logic in this func
}
}
and then in the onDrawerClosed
overrided method
@Override
public void onDrawerClosed(View view) {
if (mRunnable != null) {
mHandler.post(mRunnable);
mRunnable = null;
}
}
Hope this helps!
I would suggest you to use fragments for navigation drawer and to solve this issue of drawer not closing properly, I found this article very useful (using fragments). http://www.michenux.net/android-asynctask-in-fragment-best-pratices-725.html
