我正在使用Tabbed Activity。 在每日提醒/特别提醒中，保存按钮不起作用。 我给了正确的id，链接和OnClickListener。但它只是不起作用。
Reminders Activity is a simple activity with List ReminderTabActivity s Tabbed Activity 这里是onCreateView of ReminderTabActivity，其中正在调用片段。
public class ReminderTabActivity extends AppCompatActivity implements DailyReminderFragment.OnMessageSetListener {
/**
* The {@link android.support.v4.view.PagerAdapter} that will provide
* fragments for each of the sections. We use a
* {@link FragmentPagerAdapter} derivative, which will keep every
* loaded fragment in memory. If this becomes too memory intensive, it
* may be best to switch to a
* {@link android.support.v4.app.FragmentStatePagerAdapter}.

// primary sections of the activity.

这是布局 - `
<!-- TODO: Update blank fragment layout -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_height="wrap_content"

<TimePicker

android:layout_height="wrap_content"
android:layout_below="@+id/etTitle"
android:id="@+id/timePicker"

我可以看到布局，但它没有在控制台中显示Log.d消息，也没有按钮onClickListener正在运行。
你们有什么人认为我在这里做错了？
答案 0 :(得分：1)
哪个片段有你在帖子的最后添加的oncreateview方法？我认为你应该将onclicklistener和其他视图创建移动到oncreateView of placeholderfragment相应的视图，以便工作，如果不是
