ProgressDialog:如何防止泄漏窗口 [英] ProgressDialog : how to prevent Leaked Window
问题描述
我正在使用 ProgressDialog 来防止用户在设备从互联网下载内容时进行交互.
I'm using ProgressDialog to prevent the user from interacting while the device is downloading stuff from internet.
一切正常，直到我的客户设法产生这个错误:
everything was working fine until my client managed to produce this bug :

我不知道如何解决这个问题.
and I have no idea how to fix this.
任何想法是什么导致了这个以及如何解决它?
any ideas what causes this and how to solve it ?
日志将错误追溯到这一行:
The log traces back the error to this line :
progressDialog = ProgressDialog.show(PixelRainActivity.staticThis, "",PixelRainActivity.staticThis.getResources().getString( R.string.draftProgressMessage), true);
改成这样能解决问题吗:
would it solve the problem if I changed it to this :
this.runOnUiThread(new Runnable() {
public void run() {
progressDialog = ProgressDialog.show(PixelRainActivity.staticThis, "",PixelRainActivity.staticThis.getResources().getString( R.string.draftProgressMessage), true);
}
});
推荐答案
泄漏可能来自您的 PixelRainActivity.staticThis 属性.如果您保留对活动的引用，即使在此活动已被销毁之后，您也会发生内存泄漏.
The leak comes probably from your PixelRainActivity.staticThis attribute. If you’re keeping a reference to an activity, even after that this activity has been destroyed, you have a memory leak.
最简单的修复方法是改用应用程序的Context.将方法 onCreate() 中的 staticThis = this 行更改为 staticThis = this.getApplicationContext() 并且它应该可以工作(并更改类型staticThis 到 Context 如果还不是这样)
The easiest way to fix is to use the application’s Context instead. Change your staticThis = this line in the method onCreate() to staticThis = this.getApplicationContext() and it should work (and change the type of staticThis to Context if this is not already the case)
