我试图从一个片段移动到另一个片段.它在片段事务期间显示以下错误 -

Answer 1

使用fragmentTransaction.replace(R.id.container,fragment)它时,将删除容器中已有的任何碎片,并将新的碎片添加到同一容器中.

现在我可以建议你2件事.首先,如果你想使用fragmentTransaction.replace(android.R.id.content, fragment);你现在正在做的事情,那么就不要为你的Activity使用设置内容setContentView.这应该可以正常工作.要知道究竟android.R.id.content是什么,你可以参考这个stackoverflow问题和回答

还是其次,在布局你Activity有一个FrameLayoutid为content.然后使用

fragmentTransaction.replace(R.id.content, fragment);  
fragmentTransaction.addToBackStack(null);//add the transaction to the back stack so the user can navigate back
// Commit the transaction
fragmentTransaction.commit();  

希望这可以帮助.

更多信息:

从你的评论看来,你在使用FrameLayout你Activity的布局(不是任何Fragment布局)的想法中遇到了一些问题.从文件中

FrameLayout旨在阻止屏幕上的某个区域显示单个项目.通常,FrameLayout应该用于保存单个子视图,因为很难以可扩展到不同屏幕大小而儿童不会相互重叠的方式组织子视图.

因此,主要目的FrameLayout是阻止适合最大子视图所需的区域.如果使用FrameLayoutas作为Fragment容器,则可以确保始终具有可用空间以容纳最大Fragment的布局.

所以你可以FrameLayout在你Activity的布局xml文件中得到这样的东西

<FrameLayout
    android:id="@+id/content"
    android:layout_height="match_parent"
    android:layout_width="match_parent">
 <!--you can put your existing views of your current xml here, so yes your entire xml is now inside this FrameLayout -->
</FrameLayout>

Answer 2

我不用getSupportFragmentManager().我用getChildFragmentManager(),它对我有用.你可以尝试一下.

Answer 3

如果你正试图把Fragment进入Fragment,使用getChildFragmentManager()

Answer 4

您必须在“活动”中设置附加了PhotosFragment的内容视图。

protected void onCreate(Bundle bundle) {
    super.onCreate(bundle);
    setContentView(R.layout.activity_main);

    //...
}

Answer 5

如果您使用的是ViewPager,请使用getChildFragmentManager()作为寻呼机适配器

viewPager.setAdapter(new ItemsAdapter(getChildFragmentManager()));
