        int spec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
        u.measure(spec, spec);
        u.layout(0, 0, u.getMeasuredWidth(), u.getMeasuredHeight());

        Bitmap b = getBitmapFromView(u,u.getMeasuredHeight(),u.getMeasuredWidth());

        final String root = Environment.getExternalStorageDirectory().toString();

        File myPath = new File(root + "/saved_img");
        myPath.mkdirs();
        Random generator = new Random();
        int n = 10000;
        n = generator.nextInt(n);
        String fname = "Image-"+n+".jpg";
        File file = new File(myPath, fname);
        FileOutputStream fos = null;
        if(file.exists()) file.delete();
        try{
            fos = new FileOutputStream(file);
            b.compress(Bitmap.CompressFormat.JPEG, 100, fos);
            fos.flush();
            fos.close();

        if (bgDrawable != null)
            bgDrawable.draw(canvas);
        else

  • you need to hide screenshot which is displaying after clicking button right? you dont need to close your activity right? while using your above code no screenshot is appear on screen. activity is there when i use your code. So some other code affects this and show you a screenshot on your screen. Hope you understand now? – Zaki Pathan Feb 18 '17 at 09:40

it's my mistake.after getting screenshot i set layout size on capturing image size(based on get measure width & height)i remove the below line in program it work perfectly.

u.layout(0, 0, u.getMeasuredWidth(), u.getMeasuredHeight());

because that line set saved image exact height & width into current layout.so that's error.i solved it.thanks for your help for all.thanks once again...
