android camera image

Android save view to jpg or png

I would like to write an android app that basically layers an overlay on image on another image and then I would like to save the picture with the overlay as a jpg or png. Basically this will be the whole view that I would like to save.

Sample code would be very helpful.

EDIT:

I tried out your suggestions and am getting a null pointer at the Starred Line.

 import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.Bitmap.CompressFormat;
import android.os.Bundle;
import android.os.Environment;
import android.widget.LinearLayout;
import android.widget.TextView;
public class EditPhoto extends Activity {
/** Called when the activity is first created. */
LinearLayout ll = null;
TextView tv = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv = (TextView) findViewById(R.id.text);
ll = (LinearLayout) findViewById(R.id.layout);
ll.setDrawingCacheEnabled(true);
Bitmap b = ll.getDrawingCache();
File sdCard = Environment.getExternalStorageDirectory();
File file = new File(sdCard, "image.jpg");
FileOutputStream fos;
try {
fos = new FileOutputStream(file);
*** b.compress(CompressFormat.JPEG, 95,fos);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
