不止一次按下按鈕

當按鈕被按下不止一次時，我正在關閉力量。我有一個條件，如果互聯網連接，然後谷歌地圖將顯示。如果互聯網沒有連接，那麼我已經保持一個警告框顯示檢查我們的互聯網連接。所以問題在這裏。如果按下按鈕時互聯網未連接，則顯示警報框。但如果多次點擊，它會顯示FORCE CLOSE。我已經把在catch塊alertbox顯示..不止一次按下按鈕

case R.id.geocode_button: // Place name as selected by the user. 

      placeName = placeText.getText().toString(); 
      clik=1;   
      placenametemp = placeName; 
      System.out.println(""+placenametemp); 

      String [] optionArray = new String[numberOptions]; 
      Geocoder gcoder = new Geocoder(this); 

      try 
      { 
           ///// code to display google map 


      } 
      catch (IOException e) 
      { 
      if(!dialogShown) 
       { 
        dialogShown = true; 
        //Show your dialog 

       new 
     AlertDialog.Builder(this).setIcon(R.drawable.icon).setTitle(
       " Check your Internet 
     Connection!").setPositiveButton("OK", 
       new DialogInterface.OnClickListener() 
       { 

        @Override 
        public void onClick(DialogInterface dialog, 
        int which) 
        { 
         dialogShown = false;  
         // TODO Auto-generated method stub 
         dialog.cancel(); 
        } 
       }).show(); 

       Log.e("Geocoder", "I/O Failure; is network  
                   available?",e); 
      } 
          }

您不能顯示的警告對話框中一個以上的時間，所以把像檢查這

首先創建一個類級別變量

public boolean dialogShown = false;

然後在這裏case R.id.geocode_button

if(!dialogShown){ 
dialogShown = true; 
//Show your dialog 
}

然後在對話框ok按鈕單擊listener

dialogShown = false;

更新

檢查您的網絡連接像這樣的離子

void boolean checkInternet(){ 
    NetworkInfo i = conMgr.getActiveNetworkInfo(); 
    if (i == null) 
    return false; 
    if (!i.isConnected()) 
    return false; 
    if (!i.isAvailable()) 
    return false; 
    return true; 
}

我已更新我的catch塊..Sir我猜問題不是因爲警報框因爲剛剛嘗試過與Toast味精同樣的情況，並且當按鈕被按下很多次時，我仍然收到了強制關閉 – Sindu

對。首先，這不是檢查互聯網連接是否可用的方法。但這不是問題。 第一個問題是CalledFromTheWrongThread異常，這意味着某個地方你試圖從另一個線程訪問UI元素。永遠不要這樣做。我猜你有一個AsyncTask嘗試以不允許的方式發佈一些更新。 （在com.journey.snoozer.ShowTheMap.mapProgress（ShowTheMap.java:143））

這裏的主要問題是WindowLeaked異常向下幾行。例如，當你退出一個活動並嘗試訪問一個對話框時，會發生這種情況。 （方向更改等）由於您有涉及AsyncTask的其他異常，我想知道是否在發生IO異常時取消第一個AsycTask。

因此，請確保在onPause（）中的AsyncTask上使用.cancel（），並在任務創建的對話框上使用dissmiss（）。
