Android 如何用片段替换ViewPager
我有下面的布局Android 如何用片段替换ViewPager,android,android-fragments,android-viewpager,fragmenttransaction,Android,Android Fragments,Android Viewpager,Fragmenttransaction,我有下面的布局 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_verti
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<android.support.v4.view.ViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</android.support.v4.view.ViewPager>
这不是重新绘制ViewPager我该怎么办?您可以创建一个包含ViewPager的片段,然后替换该片段
public class ViewPagerContainerFragment extends Fragment {
private ViewPager mViewPager;
public ViewPagerContainerFragment() { }
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.view_pager_container_fragment, container, false);
// Set up the ViewPager, attaching the adapter and ...
mViewPager = (ViewPager) root.findViewById(R.id.viewPager);
// do other stuff...
return root;
}
}
查看\u pager\u container\u fragment.xml
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/rlMain"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<android.support.v4.view.ViewPager
android:id="@+id/viewPager"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</RelativeLayout>
代码后面的某个地方:(如果您想-用另一个片段替换ViewPagerFragment)
请确保没有造成任何内存泄漏,并正确设置适配器。文档说明-
替换添加到容器中的现有片段。这本质上与为所有当前添加的片段调用remove(Fragment)相同,这些片段是使用相同的containerWebID添加的,然后再添加(int、Fragment、String)使用此处给出的相同参数。
因此我假设您只能替换片段,而不能替换其他视图。如果尝试此解决方案,请注意导航返回行为。退房
