Android : taking Screenshot of the selected area programmatically

Question

My code is as follow :

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main         


        

Answer 1

You can wrap the contents in a layout for example LinearLayout and follow the above code for taking screenshot by using the methods on the wrapped layout.

 Bitmap bitmap;
 ViewGroup v1 = findViewById(R.id.layout_id);
 v1.setDrawingCacheEnabled(true);
 bitmap = Bitmap.createBitmap(v1.getDrawingCache());
 v1.setDrawingCacheEnabled(false);

Answer 2

Below method takes snapshot of given view which is adjustable by means of height and width then returns bitmap of it

public static Bitmap takeSnapshot(View givenView, int width, int height) {
Bitmap bm = Bitmap.createBitmap(width , height, Bitmap.Config.ARGB_8888);                
Canvas snap = new Canvas(bm);
givenView.layout(0, 0, givenView.getLayoutParams().width, givenView.getLayoutParams().height);
givenView.draw(snap);
return bm;  }
