actionBar.setHome 函数调用Application Home Activity。当它调用时，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可以不重新加载、重新加载 Home Activity，而是将 Home Activity 隐藏或为 Home Activity 存储内存。Home Activity 嵌入了字体、两个选项卡和按钮。当一个按钮来自 Home Activity 时，该 Activity 转到另一个 Activity，其中 actionBar.setHome 函数重定向 Home Activity，就像重新加载它一样。
儿童活动代码：

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 Home Activity 后的 Logcat：

Home Activity Class-> OnCreate() 中需要哪些额外的代码，或者如果已经加载，则不尝试重新加载的任何方法？或者如果函数调用另一个活动，如何让 Home Activity 隐藏？

妈的，我自己解决我的问题。不管怎样，谢谢所有这个问题的观众。

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
