推荐答案

是的，您可以使用ActivityGroup并将其嵌入其中.

Yes, you can use an ActivityGroup and embedded it in there.

public class ActivityA extends ActivityGroup {

    ...
    Intent b = new Intent(this, ActivityB.class);
    Window bWindow = getLocalActivityManager().startActivity(ActivityB.class.getName(),b);
    activityFrame.addView(bWindow.getDecorView());  // activityFrame being your FrameLayout
    ....
