Android navigation drawer right side not working

I have a navigation drawer and I try to change its opening position. I want my navigation drawer to open on the right side.

This is my navigation drawer xml code:

<ge.me.custom.CustomDrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout5"
android:layout_width="200dp"
android:layout_height="match_parent" >
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<LinearLayout
android:id="@+id/drawer"
android:layout_width="200dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#09b52f"
android:orientation="vertical" >

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >

<RelativeLayout
android:id="@+id/slidemenumainlayout"
android:layout_width="match_parent"
android:layout_height="120dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >

<ImageView
android:id="@+id/slidemenuuserimage"
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginBottom="16dp"
android:layout_marginLeft="14dp"
android:background="@drawable/ic_user_blue" />

</RelativeLayout>

<ListView
android:id="@+id/drawer_list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignRight="@+id/slidemenumainlayout"
android:layout_below="@+id/slidemenumainlayout"
android:divider="#00af25"
android:dividerHeight="1dp" >
</ListView>
</RelativeLayout>
</LinearLayout>




This is my custom drawer:

public class CustomDrawerLayout extends DrawerLayout {

public CustomDrawerLayout(Context context) {
super(context);
}

public CustomDrawerLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}

public CustomDrawerLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
widthMeasureSpec = MeasureSpec.makeMeasureSpec(
MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.EXACTLY);
heightMeasureSpec = MeasureSpec.makeMeasureSpec(
MeasureSpec.getSize(heightMeasureSpec), MeasureSpec.EXACTLY);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

}


And this code is inside the main activity:

mDrawerToggle = new ActionBarDrawerToggle(getActivity(), mDrawerLayout,
R.drawable.ic_drawer, R.string.app_name,
R.string.app_name) {

@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item != null && item.getItemId() == android.R.id.home) {
if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT)) {
mDrawerLayout.closeDrawer(Gravity.RIGHT);
} else {
mDrawerLayout.openDrawer(Gravity.RIGHT);
}
}
return false;
}
};

mDrawerLayout.setDrawerListener(mDrawerToggle);


I wrote a method to open my drawer on the right side but when I run my app, it crashes.

public void openDrawer(int gravity) {
mDrawerLayout.openDrawer(gravity);
}
openDrawer(Gravity.RIGHT);


If I call the method like this:

openDrawer(Gravity.START);


I do not get an error but the navigation drawer's start position is left.

This is my error:

java.lang.IllegalArgumentException: No drawer view found with gravity RIGHT


How can I open the navigation drawer on the right side?

Answer

Try setting layout_gravity to right in your xml:

<LinearLayout
    android:id="@+id/drawer"
    android:layout_width="200dp"
    android:layout_height="match_parent"
    android:layout_gravity="right"
    android:background="#09b52f"
    android:orientation="vertical" >
