如何在片段内设置ViewPager [英] How to set a ViewPager inside a Fragment

问题描述

我需要在一个片段内放置一个ViewPager，但是我有两个片段，片段1是我的MENU，片段2我想用作ViewPagerIndicator。

I need to place a ViewPager inside of a fragment, but I have two fragments, Fragment 1 is my MENU, and Fragment 2 I want to use as a ViewPagerIndicator.

但是一个片段不能再有另一个片段……我该怎么办？

But a fragment can't have another fragment... what do I need to do for that?

推荐答案

从Android 4.2开始，存在嵌套的片段。 http：// developer。 android.com/about/versions/android-4.2.html#NestedFragments 支持库现在还包含了对较早的Android版本的支持。

Starting in Android 4.2, there are nested fragments.http://developer.android.com/about/versions/android-4.2.html#NestedFragments The support library now also includes support for this for older Android versions.

可以做这样的事情：

@Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    ViewPager mViewPager = (ViewPager) view.findViewById(R.id.viewPager);
    mViewPager.setAdapter(new MyAdapter(getChildFragmentManager()));
    }
