我有一個TextView,一旦我點擊它,將打開一個對話框,它使用日期和時間選擇器作爲它的視圖。Android對話框沒有顯示

datetimepicker.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/linearLayout1" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

    <DatePicker 
     android:id="@+id/datePicker1" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" > 
    </DatePicker> 

    <TimePicker 
     android:id="@+id/timePicker1" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" > 
    </TimePicker> 

    <LinearLayout 
     android:id="@+id/setcancel" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" > 

     <Button 
      android:id="@+id/button1" 
      style="?android:attr/buttonStyleSmall" 
      android:layout_width="0dp" 
      android:layout_height="wrap_content" 
      android:layout_weight="1" 
      android:text="SET" /> 

     <Button 
      android:id="@+id/button2" 
      style="?android:attr/buttonStyleSmall" 
      android:layout_width="0dp" 
      android:layout_height="wrap_content" 
      android:layout_weight="1" 
      android:text="CANCEL" /> 
    </LinearLayout> 

</LinearLayout> 

這對於TextView.OnClickListener

final TextView startTime = (TextView) getActivity().findViewById(R.id.textView3);  
     startTime.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 
      final Dialog dialog = new Dialog(getActivity()); 
      dialog.setContentView(R.layout.datetimepicker); 
      dialog.setTitle("Set Date and Time"); 

      Button set = (Button) dialog.findViewById(R.id.button1); 
      Button cancel = (Button) dialog.findViewById(R.id.button2); 

      final TimePicker tp = (TimePicker)dialog.findViewById(R.id.timePicker1); 
      tp.setCurrentHour(Calendar.HOUR_OF_DAY); 
      tp.setCurrentMinute(Calendar.MINUTE); 
      tp.setOnTimeChangedListener(new OnTimeChangedListener() { 

       @Override 
       public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { 
        // TODO Auto-generated method stub 
        hour = hourOfDay; 
        min = minute; 
       } 
      }); 
      set.setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        // TODO Auto-generated method stub 
        startTime.setText(Integer.toString(hour)+ ";" + Integer.toString(min));    
       } 
      }); 

      cancel.setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        // TODO Auto-generated method stub 
        dialog.dismiss(); 

       } 
      }); 



     } 
    }); 

該問題的代碼是,一旦我點擊它什麼也不做TextView,我的意思是什麼也沒有發生,我想設置在對話框上點擊確定按鈕後,用戶設置的時間爲TextView的文本。

你有什麼建議嗎? TIA。

你忘了打電話給

Dialog.show()

最後一個問題時,我的設置按鈕,如何設置上按鈕TextView的文本單擊一下? – RieJack

我認爲你已經這樣做了:「startTime.setText(Integer.toString(hour)+」;「+ Integer.toString(min));」? –
