问题描述

谁能告诉我在Android Fragment中onAttach()和i☎联系人的使用有何不同?

Can anyone tell me what are the different of use of onAttach() and isAdded in Android Fragment?

在创建新片段的onAttach()方法时，会创建默认片段.

When create a new fragment onAttach() method creating default.

我检查了这个问题，询问有关！onDetech()和iwego()的问题，也是那里的一个答案，但我不清楚.谢谢

I checked this question, the question is asked about !onDetech() and isAdded() , also one answer there, but I am not clear with that.. Thanks

推荐答案

只需阅读javadocs即可回答:

This could be answered simply reading javadocs:

    /**
     * Called when a fragment is first attached to its context.
     * {@link #onCreate(Bundle)} will be called after this.
     */
    public void onAttach(Context context) 

和

    /**
     * Return true if the fragment is currently added to its activity.
     */
    final public boolean isAdded()
