如何从子活动中更快地加载父活动？

Question

actionBar.setHome函数调用“应用程序本地活动”。 通话时，就像重新打开应用程序一样。 我的意思是我必须等待加载“家庭活动”。 我认为可能有一种方法不重新加载，重新加载家庭活动，而是隐藏家庭活动或为家庭活动存储内存。 家庭活动嵌入了字体，两个选项卡和按钮。 当从“主页活动”中单击按钮时，该活动将转到另一个活动，在该活动中，actionBar.setHome函数将重定向“主页活动”，就像重新加载它一样。
子活动代码：

public void onCreate(Bundle savedInstanceState) {
.......................
.......................
actionBar.setHomeAction(new IntentAction(this, createIntent(this),
            R.drawable.ic_title_home_default));
  }
  //calling Parent Activity
   private static Intent createIntent(Context context) {
    Intent i = new Intent(context, CustomTabActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    return i;
  }

从另一个活动调用家庭活动后，Logcat：

家庭活动类-> OnCreate（）中还需要哪些其他代码，或者一旦已经加载就不要尝试重新加载的任何方法？ 或者，如果函数调用另一个活动，如何隐藏Home Activity？

Answer 1

该死，我自己解决问题。 谢谢所有对此问题的观众。

public void onCreate(Bundle savedInstanceState) {
.......................
.......................
actionBar.setHomeAction(new IntentAction(this, createIntent(this),
            R.drawable.ic_title_home_default));
  }
  //calling Parent Activity
   private static Intent createIntent(Context context) {
    Intent i = new Intent(context, CustomTabActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
    return i;
  }

更改为：FLAG_ACTIVITY_REORDER_TO_FRONT
