如何從子活動中更快地加載父活動？

Question

actionBar.setHome函數調用“應用程序本地活動”。 通話時，就像重新打開應用程序一樣。 我的意思是我必須等待加載“家庭活動”。 我認為可能有一種方法不重新加載，重新加載家庭活動，而是隱藏家庭活動或為家庭活動存儲內存。 家庭活動嵌入了字體，兩個選項卡和按鈕。 當從“主頁活動”中單擊按鈕時，該活動將轉到另一個活動，在該活動中，actionBar.setHome函數將重定向“主頁活動”，就像重新加載它一樣。
子活動代碼：

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;
  }

從另一個活動調用家庭活動后，Logcat：

家庭活動類-> OnCreate（）中還需要哪些其他代碼，或者一旦已經加載就不要嘗試重新加載的任何方法？ 或者，如果函數調用另一個活動，如何隱藏Home Activity？

Answer 1

該死，我自己解決問題。 謝謝所有對此問題的觀眾。

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;
  }

更改為：FLAG_ACTIVITY_REORDER_TO_FRONT
