Answer 1

更改此文件： list_fragment.xml

    <ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

您的Fragment从ListFragement扩展。这意味着您的片段布局必须具有ID为android.R.id.list的ListView（之前它只是一个FrameLayout），所以现在它变成了ListFragment。 Android需要调用函数，因此它需要listview上的正确id，默认情况下是android.R.id.list
