Question

我在片段视图中管理onItemClickListener时遇到了一些困难。当我按下列表中的项目时，没有任何反应。请检查我的代码，如果我做得对，或者我的代码有什么问题，请告诉我。

public class People extends BaseFragment implements OnClickListener {
    static String name;
    ListView listview;
    TextView et;
    static public List<SuccessStoreyItem> success_list3 = new ArrayList<SuccessStoreyItem>();
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
        // TODO Auto-generated method stub

        View view= inflater.inflate(R.layout.home,null);
        ParserResult pr = new ParserResult();
        Button b=(Button) view.findViewById(R.id.home1);
        listview = (ListView)view.findViewById(R.id.lv_home);
        listview.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                // TODO Auto-generated method stub
                Toast.makeText(getActivity(), "ullu ka patha", Toast.LENGTH_LONG).show();
                /*Profile frg3 = new Profile();
                Bundle b3 = new Bundle();
                String username = success_list3.get(position).getStorey_id();
                b3.putString("username", username);
                frg3.setArguments(b3);
                ((MainActivity)getActivity()).launchNewFragment(frg3, R.id.tab2);
                Toast.makeText(getActivity(), "Name :"+name ,1).show();*/
            }
        });

        et=(TextView) view.findViewById(R.id.editText1);
        b.setOnClickListener(this);

        if(ParserResult.success_list2.size() != 0){
            success_list3 = ParserResult.success_list2;
        }
        listview.setAdapter(new Adapters(success_list3 ,MainActivity.mainactivity_context));
        ParserResult.success_list2 = new ArrayList<SuccessStoreyItem>();
        return view;
    }

    @Override
    public void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
        setTitle(R.string.Home);
    }
    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub
        name=et.getText().toString();
        Bundle bundle = new Bundle();
        bundle.putString("Name", name);

    Toast.makeText(getActivity(), "Name :"+name ,1).show();


        //((MainActivity)getActivity()).launchNewFragment(new Home2(),R.id.tab1);
    }


}

更新：添加了列表视图结构

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ImageView
        android:id="@+id/view_imageview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:src="@drawable/ic_launcher" />

    <TextView
        android:id="@+id/view_tv_username"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/view_imageview"
        android:layout_alignLeft="@+id/view_tv_age"
        android:layout_marginBottom="5sp"
        android:text="TextView" />

    <TextView
        android:id="@+id/view_tv_age"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@+id/view_tv_username"
        android:layout_marginLeft="26dp"
        android:layout_toRightOf="@+id/view_imageview"
        android:text="TextView" />

    <ImageButton
        android:id="@+id/ib_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_marginRight="29dp"
        android:layout_marginTop="18dp"
        android:background="#fff"
        android:src="@drawable/chevron" />

</RelativeLayout>

Answer 1

解决方案

将android:descendantFocusability="blocksDescendants"添加到ListView项目布局中的<RelativeLayout..。

可能的解释

查看listview项目布局，我看到你有一个ImageButton。碰巧ImageButton 从其所在的视图组（列表行）窃取焦点。这意味着当您单击列表行时，它始终是ImageButton捕获事件。

通过添加android:descendantFocusability="blocksDescendants"，我们阻止列表行后代窃取可聚焦性。

您可以详细了解here。

Answer 2

我认为你的listview.setadapter（）行和与之关联的数据应该在你将onclickitemlistener（）设置为listview之前出现..

ListView上的setOnItemClickListener不起作用
