android - ListView 项目不可点击

Question

我使用“ListFragment”来列出 ListView 中的项目。 ListView 的 xml 是:

<ListView
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:id="@android:id/list"
    android:layout_weight="1"
    android:dividerHeight="4dp" />

项目的 XML 布局是:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">

<TextView
    android:id="@+id/fromId"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="gone" />

<TextView
    android:id="@+id/fromName"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:singleLine="false"
    android:layout_weight="1" />

<TextView
    android:id="@+id/toId"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="gone" />

<TextView
    android:id="@+id/toName"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:singleLine="false"
    android:layout_weight="1"/>
</LinearLayout>

fragment 中还有以下内容:

@Override
public void onListItemClick(ListView l, View v, int position, long id) {
    MyItem item = (MyItem)l.getItemAtPosition(position);
}

但是，这些项目不可点击。

我错过了什么？

你试过吗

    ListView listView = getListView();
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Toast.makeText(getActivity().getBaseContext(), "Item clicked: " +  [position], Toast.LENGTH_LONG).show();
            // Your Staff
        }
    });

或者

 getListView().setOnItemClickListener(this); // onActivityCreated()


    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,
            long id) {

        Toast.makeText(getActivity(), "Item: " + position, Toast.LENGTH_SHORT)
                .show();

    }

已编辑

    @Override
    public void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    Toast.makeText(getActivity().getBaseContext(), "Item clicked: " +  [position], Toast.LENGTH_LONG).show();
        MyItem item = (MyItem)l.getItemAtPosition(position);
    }
