代碼

if(str.equals("")) 
     {       
      ConnectivityManager connManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE); 
     NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);  
     if (mWifi.isConnected()) { 
      new Handler().postDelayed(new Runnable(){ 
       @Override 
       public void run() { 
       /* Create an Intent that will start the Menu-Activity.*/ 
       Intent mainIntent = new Intent(SplashActivity.this,MainActivity.class); 
       SplashActivity.this.startActivity(mainIntent); 
       SplashActivity.this.finish(); 
       } 
      }, SPLASH_DISPLAY_LENGHT); 
     } 
     else 
     {     
      showDialog(); 
     } 
     } 
     else 
     { 
      ConnectivityManager connManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE); 
      NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);  
      if (mWifi.isConnected()) {     
        new Handler().postDelayed(new Runnable(){ 
         @Override 
         public void run() { 
         /* Create an Intent that will start the Menu-Activity.*/ 
         Intent mainIntent = new Intent(SplashActivity.this,MainActivity.class); 
         SplashActivity.this.startActivity(mainIntent); 
         SplashActivity.this.finish(); 
         } 
        }, SPLASH_DISPLAY_LENGHT); 
       new DownloadFilesTask().execute(); 
      } 
      else 
      {     
       showDialog(); 
      }

的ShowDialog（）;

private void showDialog() 
    { 
     AlertDialog.Builder dialog = new AlertDialog.Builder(this); 
     dialog.setTitle("Attention"); 
     dialog.setMessage("No Internet Connection. Please enable the wifi. "); 
     dialog.setPositiveButton("OK", new 
       DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, 
       int whichButton) 
       { 
        new Handler().postDelayed(new Runnable(){ 
         @Override 
         public void run() { 
         /* Create an Intent that will start the Menu-Activity.*/ 
         Intent mainIntent = new Intent(SplashActivity.this,MainActivity.class); 
         SplashActivity.this.startActivity(mainIntent); 
         SplashActivity.this.finish(); 
         } 
        }, SPLASH_DISPLAY_LENGHT); 
       } 
      }); 

     dialog.show(); 
    }

你可以發佈你的代碼出錯的地方嗎？ –

生成此錯誤的代碼將對您有所幫助 – CAA

您無法將適當的上下文傳遞給對話框。 – RobinHood

嘗試使用的AsyncTask，並顯示您在onPostExecute對話框。在onPreExecute上顯示你的閃屏。

你使用這個解決方案嗎？ –

您試圖在退出活動後顯示對話框。

解決方法是在您退出活動之前創建的對話框上調用dismiss（），例如，在onPause（）中。

視圖具有對其父上下文的引用（從構造函數參數中獲取）。如果您在不銷燬對話框和其他動態創建的視圖的情況下離開活動，它們仍然持有對您的活動的引用（如果您將此引用創建爲上下文：如新ProgressDialog（this）），則GC不能收集它，導致內存泄漏。

原來的答案是HERE由Alex
