Android微調器在敲擊時崩潰

我有一個微調器，它首先正確填充選項列表。然後，當我切換活動並返回並點擊微調器時，應用程序崩潰（請參閱下面的日誌）。Android微調器在敲擊時崩潰

 spinner1 = (Spinner) view.findViewById(R.id.fldWithSpinner1); 


     ArrayAdapter<?> aa = new ArrayAdapter<Object>(LocationsUI.this, 
       android.R.layout.simple_spinner_item, 
       availableLocations); 
     aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
       spinner1.setAdapter(aa);

每當我切換到LocationsUI時，都會創建微調器。微調器僅在第一時間顯示LocationsUI工程確定，當我重新顯示LocationsUI後的微調挖掘每一次之後，它會崩潰：

能否請你告訴我正確的方向解決這個問題？

隨着你的logcat說：android.view.WindowManager$BadTokenException: Unable to add window -- token [email protected] is not valid; is your activity running?

，當你表示不再存在上下文的對話框中就會發生這種情況。這裏是一個可以解釋你，你做錯了什麼確切的鏈接：http://dimitar.me/android-displaying-dialogs-from-background-threads/

，這裏是可以幫助您從相同的鏈接代碼：

private Handler myHandler = new Handler() { 
    @Override 
    public void handleMessage(Message msg) { 
    switch (msg.what) { 
     case DISPLAY_DLG: 
     if (!isFinishing()) { 
     showDialog(MY_DIALOG); 
     } 
     break; 
    } 
    } 
};
