我正在开展一个学校项目,其中我有一个带有两个片段的main_activity。其中一个片段包含listview。 listview通过适配器填充,这一切似乎工作正常。但是我尝试将OnItemClickListener添加到此列表视图中,我真的无法解决它。
这是listview(overview_fragment.xml)的片段:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
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"
//android:descendantFocusability="blocksDescendants"
>
<ListView
android:id="@+id/list_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout_editor_absoluteX="8dp"
tools:layout_editor_absoluteY="8dp" />
这是我在overviewFragment.java中添加监听器的地方:
public class OverviewFragment extends Fragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.overview_fragment, container, false);
final ListView listView = view.findViewById(R.id.list_view);
AdapterView.OnItemClickListener mMessageClickedHandler = new
AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long
id) {
Log.d(OverviewFragment.class.getSimpleName(), "listener in overviewFragment");
}
};
listView.setOnItemClickListener(mMessageClickedHandler);
return view;
}
这是我使用的列表项目:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:descendantFocusability="blocksDescendants">
<TextView
android:id="@+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_below="@id/name"
/>
答案 0 :(得分:0)
您应该为点击监听器添加项目和适配器。移除var SomeView = View.extend({
parentMethod: function() {
//some parent code
}
})
var MyView = SomeView.extend({
parentMethod: function() {
//keep parents statements and extend
}
})
,android:descendantFocusability="blocksDescendants"
会移除blockDescendants
