Android: SlidingDrawer disappears under SurfaceView
- by ykrasik
Hi,
I'm trying to create a SlidingDrawer with LinearLayout content over a FrameLayout.
At first it all seems fine, I get my SlidingDrawer's handle at the bottom of the screen.
But then, if I start dragging the handle up and the content starts showing, it gets clipped by the border rectangle of the handle. If I drag the handle all the way up the entire content eventually gets shown, however if I now drag the handle down, it will be clipped by the border rectangle of the content. Also, if the handle is all the way up, as soon as I start dragging it the whole content disappears.
I can still click on where the handle should be on the screen, drag it and the content would show, but I need to guess where the handle is.
What seems to be causing this is the fact that I have a SurfaceView in the xml file just before SlidingDrawer.
Removing the view from the xml solves this problem, however I need this view.
Here's the xml:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- Removing this DrawView from here solves the problem -->
<com.package.DrawView
android:id="@+id/main"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
<SlidingDrawer
android:id="@+id/SlidingDrawer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:allowSingleTap="true"
android:animateOnClick="true"
android:handle="@+id/slideHandleButton"
android:content="@+id/contentLayout"
android:padding="10dip">
<Button
android:id="@+id/slideHandleButton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/sliding_button">
</Button>
<LinearLayout
android:id="@+id/contentLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="@+id/clearButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Test">
</Button>
</LinearLayout>
</SlidingDrawer>
</FrameLayout>
Java:
package com.package;
import android.app.Activity;
import android.os.Bundle;
public class SlideTest extends Activity
{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
package com.package;
import android.content.Context;
import android.util.AttributeSet;
import android.view.SurfaceView;
public class DrawView extends SurfaceView
{
public DrawView(Context context, AttributeSet attrs) {
super(context, attrs);
}
}
Edit: I just noticed that if DrawView extends View and not SurfaceView this problem goes away.
However, I'm using a dedicated drawing thread and according to the documentation (and LunarLander example) when using a dedicated drawing thread, it should draw to a SurfaceView.
Any help would be greatly appreciated!
