Question

我的onItemClickListener有问题。它不起作用，甚至没有检测listview中的click元素。我有几乎相同的片段相关这里是片段中的调用：

   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">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:textColor="@color/lightgraylampica"
        android:textSize="20dp"
        android:layout_marginLeft="10dp"
        android:textStyle="bold" />
</RelativeLayout>
<com.orangegangsters.github.swipyrefreshlayout.library.SwipyRefreshLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/swipe_section_swipe"
    app:srl_direction="bottom"
    android:layout_below="@+id/rewards_section_header">

    android:layout_alignParentStart="true"

// either dynamically or via XML layout inflation.

Answer 1

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

    <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
}

Answer 2

尝试在onCreateView而不是onViewCreated中粘贴此代码：

class TestModel(models.Model):
    cover = models.ImageField(upload_to='covers')

理想情况下，您应该在onCreateView中引用所有视图和小部件以获取片段和片段。 onCreate活动。试试这个代码，我希望这能解决你的问题。

在onCreate之后立即调用onViewCreated，因此应该调用showlist（）方法。

listview.setOnItemClickListener不工作
