    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT)); 
    dialog.setContentView(R.layout.coach_mark); 
    dialog.setCanceledOnTouchOutside(true); 
    View masterView = dialog.findViewById(R.id.coach_mark_master_view); 
    masterView.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      dialog.dismiss();
