Android输入框点击弹出日期选择框

// 获取 文本编辑框控制权
    EditText returnTime = findViewById(R.id.return_time);
    //                日期选择触发器
    returnTime.setOnTouchListener(new View.OnTouchListener() {
      @Override
      public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
          showDatePickDlg();
          return true;
        }
        return false;
      }
    });
    //                进入文本编辑框焦点触发日期选择器
    returnTime.setOnFocusChangeListener(new View.OnFocusChangeListener() {
      @Override
      public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {
          showDatePickDlg();
