How to make an Android SlidingDrawer slide out from the left?

I've found a simple way to do that. All you have to do is to set the rotation of 180º for the slidingDrawer, the content and the handle.You can similarly make a SlidingDrawer that descends from the top, like I did here.

Look at my examples here, first from right to left, to be able to see the differences.

<SlidingDrawer xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/slidingDrawer"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:orientation="horizontal"    android:gravity="center_horizontal"    android:handle="@+id/handle"    android:content="@+id/content">    <ImageView android:id="@+id/handle"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:src="@drawable/ic_launcher" />    <ImageView android:id="@+id/content"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:background="#FF0000"        android:src="@drawable/ic_launcher" /></SlidingDrawer>

Now look what I changed to make it sliding out from the left.

<SlidingDrawer xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/slidingDrawer"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:orientation="horizontal"    android:gravity="center_horizontal"    android:handle="@+id/handle"    android:content="@+id/content"    android:rotation="180">    <LinearLayout android:id="@+id/handle"        android:layout_width="wrap_content"        android:layout_height="wrap_content">        <ImageView android:id="@+id/imageView"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:src="@drawable/ic_launcher"            android:rotation="180" />    </LinearLayout>    <ImageView android:id="@+id/content"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:background="#FF0000"        android:src="@drawable/ic_launcher"        android:rotation="180" /></SlidingDrawer>

Note that I also created a LinearLayout to set as handle, and didn't change it's rotation, but I changed the rotation of it's child. This was to prevent a small issue I had, but everything is working fine and it's simple.

I don't think you can, other than perhaps by grabbing the SlidingDrawer source code, making changes to it, and using your modified version. You similarly cannot make a SlidingDrawer that descends from the top.

I have rewritten a class to that and made it part of my open source library. It took me almost a week to get it right. Please check out my SlidingTray in Aniqroid open source library for Android.
