java - listview.setOnItemClickListener 不起作用

Question

我的 onItemClickListener 有问题。它不起作用，甚至没有检测到 ListView 中元素的点击。我有几乎相同的片段相关这是片段中的调用:

   public void onViewCreated(View view, Bundle savedInstanceState) {
    list = (ListView) view.findViewById(R.id.listAwards);
    list.setItemsCanFocus(false);
    list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            FragmentManager fm = getFragmentManager();
            FragmentTransaction ft = fm.beginTransaction();
            Fragment fragment = new AwardDetailFragment();
            ft.replace(R.id.fragmentlayout, fragment);
            ft.commit();
            Toast.makeText(getContext(),"Test",Toast.LENGTH_LONG).show();
        }
    });

这是 xml 文件:

<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"
xmlns:app="http://schemas.android.com/apk/res-auto">


<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="56dp"
    android:background="@color/neonGreen"
    android:id="@+id/rewards_section_header"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true">

        android:layout_marginLeft="10dp"
        android:textStyle="bold" />
</RelativeLayout>

    app:srl_direction="bottom"

完整 Activity 代码:

// The onCreateView method is called when Fragment should create its View object hierarchy,
// either dynamically or via XML layout inflation.
int offset = 0;
int size = 8;
private SwipyRefreshLayout swipyRefreshLayout;

private  ListView list;

                showlist();

            }
        }

    });
    return rootView;

// This event is triggered soon after onCreateView().

为什么不在片段 ListView xml 条目中添加 android:onClick="clickFunction" 并尝试如下:

    <ListView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/listAwards"
    android:layout_below="@+id/rewards_section_header"
    android:layout_alignParentLeft="true"
    android:focusable="false"
    android:clickable="true"
    android:focusableInTouchMode="false"
    android:layout_alignParentStart="true"
    android:onClick="clickFunction"
    android:contextClickable="true" />

然后在你的片段中:

public void clickFunction(View v) {
    // Do something
}
