You can use `onLongClickListener`:
Button button; button = findViewById(R.id.<your_button_id>); button.setOnLongClickListener(new View.OnLongClickListener() { @Override public boolean onLongClick(View view) { //your code goes here return false; } });

btn1.setOnLongClickListener(this);
and impliment your class with `View.OnLongClickListener`
and then override this method
@Override public boolean onLongClick(View view) { switch(view.getId()){ case R.id. : break; } return false; }
