活动泄漏了最初添加的窗口

这个错误是什么，为什么会发生?

尝试下面的代码，它将在任何时候工作，你将解散进度对话框，它将看到它的实例是否可用。

try {
        if (null != progressDialog && progressDialog.isShowing()) {
            progressDialog.dismiss();
            progressDialog = null;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

其他回答

我也曾面临过这个问题，但我意识到这并不是因为我的对话框，而是因为ActionMode。所以如果你试图在ActionMode打开时完成活动，就会导致这个问题。在你的活动的onPause完成动作模式。

 private ActionMode actionMode;

 @Override
 public void onActionModeStarted(ActionMode mode) {
    super.onActionModeStarted(mode);
    actionMode = mode;
 }

 @Override
 protected void onPause() {
    super.onPause();
    if (actionMode != null) actionMode.finish();
 }

窗口泄漏异常有两个原因:

1)当Activity上下文不存在时显示对话框，为了解决这个问题，你应该只显示你确定Activity存在的对话框:

if(getActivity()!= null && !getActivity().isFinishing()){
        Dialog.show();
}

2)对话框不适当解散，解决使用以下代码:

@Override
public void onDestroy(){
    super.onDestroy();
    if ( Dialog!=null && Dialog.isShowing() ){
        Dialog.dismiss();
}
}

  if (mActivity != null && !mActivity.isFinishing() && mProgressDialog != null && mProgressDialog.isShowing()) {
        mProgressDialog.dismiss();
    }

我收到了同样模糊的错误信息，不知道为什么。根据前面的答案给出的线索，我将对mDialog.finish()的非gui调用更改为mDialog.dismiss()，错误消失了。这并没有影响我的小部件的行为，但它令人不安，很可能标志着一个重要的内存泄漏。

我也有同样的问题。错误不在对话框中，而是在编辑文本中。我试图改变一个异步任务内的编辑文本的值。我唯一能解决的问题就是创造一个新的可运行对象。

runOnUiThread(new Runnable(){
      @Override
      public void run() {
       ...        
      }
    });
