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"

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
}

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。
