How to capture image of any layout in background

I want to send graphs in email. So for that I have captured bitmap of that graph and save it in sdcard as image. that works successfully

private Bitmap TakeImage(View v) {
Bitmap screen = null;
 try {
     v.setDrawingCacheEnabled(true);

     v.measure(MeasureSpec.开发者_StackOverflow社区makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
          MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
     v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());

     v.buildDrawingCache(true);
     screen = v.getDrawingCache();
     v.setDrawingCacheEnabled(false); // clear drawing cache
} catch (Exception e) {
      e.printStackTrace();
}
return screen;
}

But now I want to capture that in background without showing that layout, without notify by user. My previous code does not work for that.

Inflate the view using LayoutInflater, populate the values and pass it on to the same takeImage(View v) method.

I'm not sure, and I've not tried, don't know whether this works or not. but give it a try.

Have you tried changing v.getMeasuredWidth(), v.getMeasuredHeight() to whatever values you desire?

can you use

view.getLocationOnScreen(l);
