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?

你可以通过一个简单的/愚蠢的错误得到这个异常，通过(例如)在显示AlertDialog后不小心调用finish()，如果你错过了switch语句中的break call语句……

   @Override
   public void onClick(View v) {
    switch (v.getId()) {
        case R.id.new_button:
            openMyAlertDialog();
            break; <-- If you forget this the finish() method below 
                       will be called while the dialog is showing!
        case R.id.exit_button:
            finish();
            break;
        }
    }

finish()方法将关闭Activity，但AlertDialog仍然显示!

因此，当您专注地盯着代码，寻找糟糕的线程问题或复杂的编码等时，不要只见树不见林。有时它可能只是一些简单而愚蠢的事情，如缺少break语句。：）

我正在使用一个视频播放器的对话框错误，而不是发疯(我已经测试了所有这些解决方案)

我选择了DialogFragment http://developer.android.com/reference/android/app/DialogFragment.html。

你可以在内部的DialogFragment类中返回构建器创建，只需要重写onCreateDialog

不仅尝试显示警报，而且当您完成一个特定的活动实例并尝试启动新的活动/服务或尝试停止它时，还可以调用它。

例子:

OldActivity instance;

    oncreate() {
       instance=this;
    }
    instance.finish();
    instance.startActivity(new Intent(ACTION_MAIN).setClass(instance, NewActivity.class));

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();
}
}

这可能会有所帮助。

if (! isFinishing()) {

    dialog.show();

    }
