Android save view to jpg or png

Question

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();       }          }     }

You can take advantage of a View's drawing cache.

view.setDrawingCacheEnabled(true); Bitmap b = view.getDrawingCache(); b.compress(CompressFormat.JPEG, 95, new FileOutputStream("/some/location/image.jpg")); 

Where view is your View. The 95 is the quality of the JPG compression. And the file output stream is just that.
