Datepicker和TimePicker對話框需要點擊兩次按鈕

因此，對於我的生活，我無法找到需要在開始日期點擊兩次以及選擇器對話框打開的開始時間的原因。我已經搜索了這些論壇多次，他們都主要與編輯文本字段相關，而我的是一個簡單的按鈕，但onClickListener需要兩個點擊。提前致謝。Datepicker和TimePicker對話框需要點擊兩次按鈕

這是我的課：

嗯，你的代碼看起來確定。你可以嘗試添加android:focusable="false"到你的按鈕。我很好奇，如果問題是你只是請求關注第一次點擊，而第二次實際啓動點擊。

此外，如果這不起作用，您是否可以在點擊偵聽器中以及在public void showTimePickerDialog(View v) {方法中添加一些日誌以及...是否觸發了第一次點擊。

添加可調焦語句！謝謝 – 2015-04-02 13:13:28

完美，我很高興它的工作。我與EditText有類似的問題，但我想它也適用於Buttons :) – Vesko 2015-04-02 13:25:31

嘗試添加按鈕延遲點擊它會避免多點擊

date.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      date.setEnabled(false); 
      showDatePickerDialog(main); 
      new Handler().postDelayed(new Runnable() { 
       @Override 
       public void run() { 
        date.setEnabled(true); 
       } 
      }, 100); 
     } 
    });
