Android save view to jpg or png

androidcameraimage

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();
      }

        }
    }

Best Solution

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.
