About Sliding drawer

SlidingDrawer hides content out of the screen and allows the user to drag a handle to bring the content on screen. SlidingDrawer can be used vertically or horizontally. A special widget composed of two children views: the handle, that the users drags, and the content, attached to the handle and dragged with it. SlidingDrawer should be used as an overlay inside layouts. This means SlidingDrawer should only be used inside of a FrameLayout or a RelativeLayout for instance. The size of the SlidingDrawer defines how much space the content will occupy once slid out so SlidingDrawer should usually use match_parent for both its dimensions. Inside an XML layout, SlidingDrawer must define the id of the handle and of the content:

Here is a simple example to demonstrate this.

Create a project named SlidingDrawerDemo and copy this java code into it.

package pack.coderzheaven;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.SlidingDrawer;
import android.widget.Toast;
import android.widget.SlidingDrawer.OnDrawerCloseListener;
import android.widget.SlidingDrawer.OnDrawerOpenListener;

public class slidingDrawerDemo extends Activity implements OnClickListener {

	Button slideButton,b1, b2,b3,b4;
	SlidingDrawer slidingDrawer;

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);

		setContentView(R.layout.main);
		slideButton = (Button) findViewById(R.id.slideButton);
		slidingDrawer = (SlidingDrawer) findViewById(R.id.SlidingDrawer);
		b1 = (Button) findViewById(R.id.Button01);
		b2 = (Button) findViewById(R.id.Button02);
		b3 = (Button) findViewById(R.id.Button03);
		b4 = (Button) findViewById(R.id.Button04);

		b1.setOnClickListener(this);
		b2.setOnClickListener(this);
		b3.setOnClickListener(this);
		b4.setOnClickListener(this);

		slidingDrawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {
			@Override
			public void onDrawerOpened() {
				slideButton.setBackgroundResource(R.drawable.closearrow);
			}
		});

		slidingDrawer.setOnDrawerCloseListener(new OnDrawerCloseListener() {
			@Override
			public void onDrawerClosed() {
				slideButton.setBackgroundResource(R.drawable.openarrow);
			}
		});
	}

	@Override
	public void onClick(View v) {
		Button b = (Button)v;
		Toast.makeText(slidingDrawerDemo.this, b.getText() + " Clicked", Toast.LENGTH_SHORT).show();
	}
}

Here is the main.xml code. Make sure to put the resources in the res/drawable folder.
