在onCreate方法中创建对话框- Leak

Question

当我运行我的应用程序时，我似乎间歇性地收到以下错误。

“活动泄漏了最初添加到此处的window com.android.internal.policy.impl.PhoneWindow$DecorView@40521348”

我所要做的就是在onCreate()方法中创建对话框，如下所示：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

//Create splash-screen object and pass in width and height (width and height are defined and valid, I just removed them from this post to make it more readable)

    splash = new SplashScreen(MainActivity.this, width, height);

//Create dialog that will show splash-screen 
    loading_dialog = new Dialog(MainActivity.this,android.R.style.Theme_Black_NoTitleBar_Fullscreen);

//Set and display splash screen view
    loading_dialog.setContentView(splash);
    loading_dialog.show();
}

你知道问题出在哪里吗？

Answer 1

您可以在onCreate中创建对话框，但不能显示它，因为activity还不可见。谷歌它，有一个例子如何做正确的地方…

Answer 2

我认为您需要在显示对话框之前创建它。

您需要做的是：

loading_dialog.create().show();

相反，

loading_dialog.show();

我找到了类似的Q，你可以使用它们

Activity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@44f72ff0 that was originally added here

Activity has leaked window that was originally added

Activity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@46029dd0 that was originally added here

Answer 3

这可能是因为您在关闭Activity之前没有取消()对话框。尝试在onStop()方法中对对话框执行cancel()。这应该会有帮助。希望能有所帮助。
