Question

这是“泄漏窗口”和AlertDialog下的一个记录良好的问题。我做了大量的研究，并作为一个基础的例子发布了“在AlertDialog在12月5日12点9点23分briana posy之后调用新意图”和其他人。即使在Debug下，我也无法找到Window泄漏发生的位置和原因。有人能给我一个解决方法吗？提前谢谢。

     public void SendMessageDialog(String message) {

          AlertDialog.Builder builder = new AlertDialog.Builder(this);
          if ( bkcode == 0) {       
               builder.setIcon(R.drawable.ecg);                     /* SET OK ICON */
               message = BKP_OK;
          }else {
               builder.setIcon(R.drawable.bad);               /* SET NOK ICON */
               builder.setTitle("My MESSAGE")
               .setMessage(message)                           
               .setCancelable(true)                             // allow the use of Back Button on the hardware 
               .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    public void  onClick(DialogInterface dialog, int id) {  
                    dialog.dismiss(); 
                    returnMain();

        }                 
       });
     final AlertDialog alert = builder.create(); 
     alert.show();      
      } 
     ///////////////////////////////////////////////////////////////////
     //             BACK TO THE CALLING ACTIVITY
     ///////////////////////////////////////////////////////////////////
     public void returnMain() {
          Intent intent = new Intent(CheckSDDB.this, MainActivity.class);
          intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
          CheckSDDB.this.startActivity(intent);

 }

@cYrixmorten：对不起延迟回复。你的代码运行正常。为你+1。

如果你这样做会有什么不同：

 public void returnMain() {
      if (alert != null && alert.isShowing()) {
          alert.dismiss();
      }
      Intent intent = new Intent(CheckSDDB.this, MainActivity.class);
      intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
      CheckSDDB.this.startActivity(intent);
}

在AlertDialog中按OK后，活动泄露窗口
