Activity 已泄漏窗口

在我的启动屏幕中，我做了它，以便它检测 wifi 或 3g 是否启用。如果不是，则会出现一个对话框屏幕提示用户退出并打开其中一个。如果它打开，则代码将继续。我的 logcat 中不断收到有关我的活动有泄漏窗口的错误。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？

这是我的代码：

//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();

这是一个说明为什么会出现此问题的答案：Activity 泄漏了最初添加的窗口 https://stackoverflow.com/questions/2850573/activity-has-leaked-window-that-was-originally-added

现在，在您的情况下，您已经编写了这段代码

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，您在哪里显示connectionDialog.dismiss();在驳回它之前。

在此代码中，您将通过以下方式显示对话框connectionDialog.show();但是关闭它的代码在哪里。

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");
      }
});

所以，请找到一个解决方案，它应该是这样的。

仅在已连接 wifi 的情况下在启动时显示对话框cancel()并转到下一个活动（如果未连接）cancel()一段时间后，并给出一条消息，指出 wifi 未找到或连接。
