Question

actionBar.setHome函数调用Application Home Activity。在它打电话时，就像重新打开应用程序一样。我的意思是我必须等待加载Home Activity。我认为可能有一种方法是不重新加载，重新加载Home Activity但隐藏Home Activity或存储Home Activity的内存。 Home Activity嵌入了字体，两个选项卡和按钮。当来自Home Activity的按钮时，活动转到另一个活动，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;
  }

从其他活动调用Home Activity后的Logcat：

Home Activity Class需要哪些附加代码 - ＆gt; OnCreate（）或任何方法如果已经加载，不尝试重新加载？或者如果函数调用另一个活动，如何让Home Activity隐藏？

我自己解决问题。无论如何感谢所有观众的这些问题。

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
