活动已泄露窗口

在我的启动画面中，我已将其设置为检测是否启用了wifi或3g。如果不是，则会出现一个对话框提示用户退出并打开其中一个。如果它打开，那么代码将继续。我一直在我的logcat中发现有关我的活动泄漏窗口的错误。我不知道如何解决这个问题。下面的代码和logcat。有任何想法吗？活动已泄露窗口

这里是我的代码：

//create alert dialog for wifi and 3g 
connectionDialog = new AlertDialog.Builder(SplashMain.this).create(); 
Log.d(TAG, "dialog created"); 
connectionDialog.setTitle("Wifi or 3G not detected. Please enable either Wifi or 3G"); 
connectionDialog.setButton("Exit", new DialogInterface.OnClickListener() { 
    @Override 
    public void onClick(DialogInterface dialog, int which) { 
      finish(); 
    } 
}); 

wifiHandler = new Handler(); 
setContentView(R.layout.splashscreen); //Make the splash screen load first 
Thread splashScreenTimer = new Thread(){ //create a timer for the splash screen 
    public void run(){  //create a run class 
     Looper.prepare(); //prepare looper 
     try{   //methods within the run class 
      int screenTimer =0; 
      //make it last 3 seconds - create a while loop 
      while(screenTimer <3000){ 
       sleep(100); //100= 1/10th of a second 
       screenTimer = screenTimer +100; 
      } 
      connectionState(); //check wifi stuff 
      Log.d(TAG, "checked wifi state"); 
      if(mobile == true || wifi == true){ 
       Log.d(TAG, "wifi is true"); 
       connectionDialog.dismiss(); 
       startActivity (new Intent("ravebox.dev.sdr.CLEARSCREEN")); 
       finish(); 
       Log.d(TAG, "started activity"); 
      } 
      if(mobile == false || wifi == false){ 
       Log.d(TAG, "wifi is false"); 
       wifiHandler.post(new Runnable() { 
        @Override 
        public void run() { 
         Log.d(TAG, "show dialog"); 
         connectionDialog.show(); 
         Log.d(TAG, "show'd dialog"); 
        } 
       }); 
      }//add activity to the manifest 
     } catch (InterruptedException e) { 
      e.printStackTrace(); 
     }finally{ 
      //finish(); 
     } 
    } 
}; 
splashScreenTimer.start();

这里有一个答案是说明了为什么这个问题发生：Activity has leaked window that was originally added

现在，你如果你写了这个代码

if(mobile == true || wifi == true){ 
     Log.d(TAG, "wifi is true"); 
     connectionDialog.dismiss(); 
     startActivity (new Intent("ravebox.dev.sdr.CLEARSCREEN")); 
     finish(); 
     Log.d(TAG, "started activity"); 
}

在上面的代码中有Y在解散前显示connectionDialog.dismiss();。

而在此代码中，您显示的对话框是connectionDialog.show();，但代码的位置在哪里？

所以，请找到一个解决方案，它应该是这样的。

仅在启动时显示对话框，如果wifi已连接cancel()它并且移动到下一个活动，如果没有连接cancel()它在某个时间后发出一条消息，指出wifi没有找到或连接。

我的猜测是因为你正在更新的线程中的UI。特别是，这个代码块：


    if(mobile == true || wifi == true){ 
     Log.d(TAG, "wifi is true"); 
     connectionDialog.dismiss(); 
     startActivity (new Intent("ravebox.dev.sdr.CLEARSCREEN")); 
     finish(); 
     Log.d(TAG, "started activity"); 
    }

作为替代，你可能想使用CountDownTimer为递减计数，并在onFinish检查上面的代码（）方法

解决方案一：
在完成您的活动之前解雇您的AlertDialog。

解决方法二：
添加下面的字段中为活动的AndroidManifest.xml。

android:configChanges="orientation|keyboardHidden|navigation"

什么第二方法实际上呢？ – aProgrammer

发现可能引发异常
我得到了同样的异常的任何代码时，“网址”是错误的一样如下：

String url = String.format(SOAP_REGISTER_URL, serviceCenterAddress); 
    HttpTransportSE androidHttpTransport = new HttpTransportSE(url);

刚刚确立正确的URL运行
