Disable EditText context menu

the solution is very simple

public class MainActivity extends AppCompatActivity {

EditText et_0;

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

    et_0 = findViewById(R.id.et_0);

    et_0.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
        @Override
        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            //to keep the text selection capability available ( selection cursor)
            return true;
        }

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            //to prevent the menu from appearing
            menu.clear();
            return false;
        }

        @Override
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            return false;
        }

        @Override
        public void onDestroyActionMode(ActionMode mode) {

        }
    });
   }
}
