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:
- Make the same DrawerToggle button on the right side, with the same behavior and animation as the left side.
- 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.
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>

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
}
}
};
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
See: http://developer.android.com/reference/android/support/v4/app/ActionBarDrawerToggle.html
I have solved adding this code in the onOptionsItemSelected method:
switch (item.getItemId()) {
case android.R.id.home:
if (mDrawerLayout.isDrawerOpen(mDrawerList_right)){
mDrawerLayout.closeDrawer(mDrawerList_right);
}
mDrawerLayout.openDrawer(mDrawerList_left);
}
break;
case R.id.action_drawer:
if (mDrawerLayout.isDrawerOpen(mDrawerList_left)){
mDrawerLayout.closeDrawer(mDrawerList_left);
}
mDrawerLayout.openDrawer(mDrawerList_right);
}
default:
break;
}
I have added an action button and overrided the home button of the actionbar
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);
}
}
});
