Java 在片段列表视图中显示字符串列表

我想在一个片段的ListView中显示一个字符串列表，我的问题是，只有当我设置适配器时，它才会在打开时崩溃

public class MessengerUtil extends Content
{
    private final static String[] CONTENT ={"Joe", "Dv", "Nola", "Jimmy"};
    public MessengerUtil(LayoutInflater inflater, ViewGroup container) {
        super(inflater, container);
    }

    @Override
    public View displayContent() {
        View view = inflater.inflate(R.layout.messenger_frag, container, false);
        ArrayAdapter<String> adapterA = new ArrayAdapter<String>(HomeActivity.getInstance().getApplicationContext(),R.layout.messenger_frag,CONTENT);
        ListView lv = (ListView) view;
        lv.setAdapter(adapterA);
        return view;
    }
}

---

您可以发布崩溃吗？添加到末尾的日志Cat不确定这是否会解决您的问题，但您没有将

ListView

设置为xml中声明的

ListView

。这应该类似于

ListView lv=（ListView）view.findViewById（R.id.MessagesList）

。他在这行中这样做：''ListView lv=（ListView）view；因为整个视图是ListView。我想您需要将方向属性设置为ListViewNope同样的问题，我甚至将上下文更改为视图上下文，但仍然没有任何更改

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="match_parent"
    android:layout_width="wrap_content"
    android:id="@+id/MessagesList"
    />
