问题"已泄漏窗QUOT;在对话 [英] Problem with "has leaked window" on dialog
问题描述
我写一个Android应用程序给用户打电话基于他试图拨打该号码不同的替代数量的选项。
要做到这一点我有被称为广播接收器,获取的数量,检查是否有替代品,然后显示对话框启动一个新的活动来做到这一点,因为它不能对自己做的。
一切都只是活动确定出现的对话框之前关闭掉,所以我得到一个窗口泄露的例外,但我不知道怎样才能让它工作,等待对话的结果(注释在NumberDialog类环路)的结果也不例外,但没有对话框。

看来我无法激活其他活动同时在打电话的过程。
但是,这是不是我是想,停止显示一个对话框,当前呼叫,然后开始一个新的不同的数字。
所以,解决办法是为在主叫方类改变为简单:数= NULL;
对于 setResultData(NULL);
这的确结束通话,并让我的新的活动,以显示其对话框。
I am writing an android app to give the user the option to call a different alternative number based on the number he tried to call. To do that I have BroadCastReceiver that gets the number being called, checks if there are alternatives and then to show the dialog it starts a new activity to do that as it can not do on its own. Everything is ok except the activity get closed before the dialog appears, so I get a window leaked exception but I can not see how I can make it works, waiting for the result of the dialog (uncomment the loop in the NumberDialog class) results in no exception but no dialog.

It seems that I can not activate other Activity while in the phone call process.
But that was not what I was trying, stopping the current call showing a dialog and then starting a new one with different number.
So the fix is as simple as changing on the Caller class:
number = null;
for
setResultData(null);
which indeed ends the calls and allow my new activity to show its dialog.
