I have not tried it yet but i dont see why it would't work with something like this:
<android.support.v4.widget.SlidingPaneLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/sliding_pane_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
android:id="@+id/content_pane"
android:name="package.DetailFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:layout_marginRight="60dp"
/>
<fragment
android:id="@+id/list_pane"
android:name="package.MyListFragment"
android:layout_width="300dp"
android:layout_height="match_parent"
android:layout_gravity="left"
/>
This way you would have the ListFragment on the right side.
Now which one you want to have opened first is up to you.
If you wanted to have the left side showing first you'd need to have something like this in the onCreate method of your MainActivity:
private SlidingPaneLayout mSlidingLayout;
mSlidingLayout = (SlidingPaneLayout) findViewById(R.id.sliding_pane_layout);
mSlidingLayout.setPanelSlideListener(new SliderListener());
mSlidingLayout.openPane();
even tho i'm late i hope this helps.
