DrawerLayout Double Drawer (Left and Right Drawers

Question

I have an application, in which i want to implement a double drawer - one from the left and one from the right. Left drawer is for app navigation, right drawer is for result filtering.

So, the layout is like this:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/light_grey"
        android:orientation="vertical">

        <GridView
            android:id="@+id/gridview"
            style="@style/GridViewStyle"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:gravity="center"
            android:horizontalSpacing="7dp"
            android:stretchMode="columnWidth"
            android:verticalSpacing="7dp" />
    </LinearLayout>

    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#111"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" />

    <ListView
        android:id="@+id/right_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:background="#111"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>

You can clearly see here "left_drawer" and "right_drawer", and their respective gravity - "start" and "end" And this actually works! You can pull them both out.

The problem is, when i implement the DrawerToggle - it only opens the left drawer, and does not close the right one, so if the right drawer is opened and i press the DrawerToggle button - the left drawers opens ALSO, and overlaps the right drawer.

There are a couple of solutions i'am trying to get:

1. Make the same DrawerToggle button on the right side, with the same behavior and animation as the left side.
2. Make the drawer on the opposite side of the drawer i am trying to open - automatically close (if the left drawer is open and i press the toggle of the right drawer and vise-versa).

And i haven't figured how to do that, because DrawerToggle accepts the DrawerLayout itself as a parameter, and not the individual drawers...

I am using the Support Library.

Anyone have any ideas? Thank you in advance.

Answer 1

Here is my short solution for all who want to prevent the animation of drawer indicator if they swipe the right view. Simply implement the onDrawerSlide Method like this.

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer_white, 0, 0) {

    @Override
    public void onDrawerClosed(View view) {
       invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
    }

    @Override
    public void onDrawerOpened(View drawerView) {
       invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
    }

    @Override
    public void onDrawerSlide(View drawerView, float slideOffset) {
       if (drawerView == mSlidingMenuNavigationList) {
           super.onDrawerSlide(drawerView, slideOffset);
       }
       else {
          // do nothing on all other views
       }
    }
};

Answer 2

make a custom item and add it the right, pass to it the right drawer.

final ToggleButton ic_nav = (ToggleButton) customNav.findViewById(R.id.ic_nav);

        ic_nav.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View arg0)
            {
                if ( mDrawerLayout.isDrawerOpen(mDrawerList) && arg0.isSelected()) {
                    mDrawerLayout.closeDrawer(mDrawerList);
                    arg0.setSelected(false);
                }
                else if (!mDrawerLayout.isDrawerOpen(mDrawerList) && !arg0.isSelected()){
                    mDrawerLayout.openDrawer(mDrawerList);
                    ic_nav.setSelected(false);
                    arg0.setSelected(true);
                }
            }
        });

Answer 3

You can call it like this in a ToggleButton's handler for example :

mDrawerLayout.openDrawer(mDrawer);
mDrawerLayout.closeDrawer(mDrawer);

Where mDrawer is a reference to the specific drawer you need to open (be it a view or a layout), in your case, the actual ListView you wish to display.

Here is the code for a Double Drawer Activity than can be extended by other activities to implement the double drawer, assuming they have a layout like the one propposed by OP.

    public class DoubleDrawerActivity extends ActionBarActivity {

    private DrawerLayout mDrawerLayout;
    private ActionBarDrawerToggle mDrawerToggle;
    private View mLeftDrawerView;
    private View mRightDrawerView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
    }

    @Override
    protected void onStart() {
        super.onStart();

        if(mDrawerLayout == null || mLeftDrawerView == null || mRightDrawerView == null || mDrawerToggle == null) {
            // Configure navigation drawer
            mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
            mLeftDrawerView = findViewById(R.id.left_drawer);
            mRightDrawerView = findViewById(R.id.right_drawer);
            mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_navigation_drawer, R.string.drawer_open, R.string.drawer_close) {

                /** Called when a drawer has settled in a completely closed state. */
                public void onDrawerClosed(View drawerView) {
                    if(drawerView.equals(mLeftDrawerView)) {
                        getSupportActionBar().setTitle(getTitle());
                        supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
                        mDrawerToggle.syncState();
                    }
                }

                /** Called when a drawer has settled in a completely open state. */
                public void onDrawerOpened(View drawerView) {
                    if(drawerView.equals(mLeftDrawerView)) {
                        getSupportActionBar().setTitle(getString(R.string.app_name));
                        supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
                        mDrawerToggle.syncState();
                    }                   
                }

                @Override
                public void onDrawerSlide(View drawerView, float slideOffset) {
                    // Avoid normal indicator glyph behaviour. This is to avoid glyph movement when opening the right drawer
                    //super.onDrawerSlide(drawerView, slideOffset);
                }
            };

            mDrawerLayout.setDrawerListener(mDrawerToggle); // Set the drawer toggle as the DrawerListener
        }
    }

    @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);
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {

        // If the nav drawer is open, hide action items related to the content view
        for(int i = 0; i< menu.size(); i++)
            menu.getItem(i).setVisible(!mDrawerLayout.isDrawerOpen(mLeftDrawerView));

        return super.onPrepareOptionsMenu(menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        switch(item.getItemId()) {
            case android.R.id.home:
                mDrawerToggle.onOptionsItemSelected(item);

                if(mDrawerLayout.isDrawerOpen(mRightDrawerView))
                    mDrawerLayout.closeDrawer(mRightDrawerView);

                return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

You can use NavigationView from material design.

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view2"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer1" />

</android.support.v4.widget.DrawerLayout>

Answer 6

Use the gravity constant (Gravity.LEFT or Gravity.RIGHT) of whatever drawer you want to close (as you open the other one) in onOptionsItemSelected() as shown below.

public boolean onOptionsItemSelected(MenuItem item) {
    if (mDrawerToggle.onOptionsItemSelected(item)) {

       // Close the right side drawer if visible
       if(mDrawerLayout.isDrawerVisible(Gravity.RIGHT)) {
           mDrawerLayout.closeDrawer(Gravity.RIGHT);
       }
       return true;
    }

    // Regular stuff
    switch (item.getItemId()) {
    case R.id.action_example:
        Toast.makeText(getActivity(), "Example action.", Toast.LENGTH_SHORT).show();
        return true;
    }

    return super.onOptionsItemSelected(item);
}

mDrawerToggle = Listener object implementing DrawerLayout.DrawerListener
