Considering that we want to take the screenshot when a button is clicked, the code will look like this:

findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {
       Bitmap bitmap = takeScreenshot();
       saveBitmap(bitmap);
   }
});

Calling getDrawingCache(); will return the bitmap representing the view or null if cache is disabled, that’s why setDrawingCacheEnabled(true); should be set to true prior invoking getDrawingCache().

public Bitmap takeScreenshot() {
   View rootView = findViewById(android.R.id.content).getRootView();
   rootView.setDrawingCacheEnabled(true);
   return rootView.getDrawingCache();
}

This code is from this website The website also contains the code to save the screenshot taken.

Also question is possible duplicate of how to take a screen shot on a button click can anyone provide a android code
