Navigation drawer doesn't close

Question

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>

Answer 1

have you tried :

mDrawerLayout.closeDrawer(drawerListView);

You can add this before calling startActivity()

Answer 2

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

Answer 3

Call

drawer.closeDrawer(navList);

in onItemClick() method

Answer 4

Try

drawer.closeDrawer(Gravity.START);

Your drawer gravity is start so Use that to close the corresponding drawer

Answer 5

I didn't see any code where you are closing the ListView from drawer... close the ListView Drawer on ListItem click...

    navList.setOnItemClickListener(new AdapterView.OnItemClickListener(){
        @Override
        public void onItemClick(AdapterView<?> parent, View view, final int pos,long id){
            drawer.closeDrawer(navList);
            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;
            }
        }
    });

Answer 6

You need to close the drawer on list item click

drawer.closeDrawer(navList);

Also what is the use of FrameLayout in your xml. It is not used as a container to add or replace fragments

Answer 7

call the drawer.closeDrawer(navList); function before switch case

Answer 8

use

if(drawer.isDrawerOpen(navList))  
  {  
      drawer.closeDrawer(navList);      
  }

In onResume() and start of onItemClick() method.

or you can try another approach..run a Ui thread when you are selecting drawer item

private void selectDrawerItemItem(final int position){

     //Toast.makeText(getApplicationContext(), "ItemClicked", Toast.LENGTH_SHORT).show();

     darwer.closeDrawer(navList);

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            Fragment fragment = new Fragment(Activity.this);
            Bundle args = new Bundle();
            args.putInt(Fragment.ARG_PLANET_NUMBER, position);
            fragment.setArguments(args);

            FragmentManager fragmentManager = getSupportFragmentManager();
             fragmentManager.beginTransaction().replace(R.id.content_frame,fragment).commit();

            // update selected item and title, then close the drawer
            navList.setItemChecked(position, true);

            setTitle(" " + navListTitles[position]);
        }
    }, 200);


    // update the main content by replacing fragments


}

Answer 9

I was having the same problem.

I used

mDrawerLayout.closeDrawer(drawerListView);

before starting my new activity. It beautifully slides the drawer back in.

Answer 10

private DrawerLayout mDrawerLayout;
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerLayout.closeDrawers();

it works

Answer 11

Here is the code: Lets say you have the drawer class

in your activity call the class as and make a vaiable and assign it(put the drawer layout within a fragment for smoother user experience)

Drawer drawer;
drawer = (Drawer)getActivity().getSupportFragmentManager().findFragmentById(R.id.theid);
drawer.mDrawerLayout.closeDrawer(Gravity.END);
//End for right and Start for left

Hope it helps
