从重建prevent任务管理器在任务最后显示的活动 [英] prevent task manager from recreating last displayed activity in a task
问题描述
该方案是:
启动应用程序,启动活动A,定位到B,然后到C preSS home键。 Ç被破坏。调出任务管理器,preSS在我的应用程序的图标。活动C的再创造。我怎样才能让这种行为停止?我想会回去活性的。
launch app, start activity A, navigate to B, then to C press home button. C gets destroyed. Bring up task manager, press on my app's icon. Activity C is being recreated. How can I make this behaviour cease ? What I would like would be to go back to activity A.
我能得到这个最接近的是通过开展活动B,C与Intent.FLAG_ACTIVITY_NO_HISTORY。但有了这个标志的问题是,它prevents活动B,C从整个应用程序的生命不断被重新创建(它们应该是可创建一次任务管理器导致用户A)。
The closest I could get to this was by launching activities B,C with Intent.FLAG_ACTIVITY_NO_HISTORY. But the problem with this flag is that it prevents activities B,C from ever being re-created throughout the app's life (they should be creatable once task manager leads user to A).
编辑:观察在Intent.FLAG_ACTIVITY_NO_HISTORY情况下,如果我用这个方法,而不是相同的行为:
same behaviour observed as in Intent.FLAG_ACTIVITY_NO_HISTORY case if I use this approach instead:
class C extends Activity
{
...
@Override
protected void onDestroy()
{
// last resort
finish();
super.onDestroy();
//finish();
}
}
我无法导航回活动ç一旦它的onDestroy()被调用一次:(
I can not navigate back to activity C once it its onDestroy() has been called once :(

推荐答案
编辑Manifest.xml文件,并在您不希望指定的活动得到重建这样的:
Edit your Manifest.xml file and specify in the activity you don't want to get recreated this:
android:launchMode="singleTask"
或者根据您的需要使用其他属性。去 这里详细交代。
