列表视图onitemclick监听器不工作 [英] Listview onitemclick listener is not working

问题描述

我在一个Android应用程序，我需要创建 onItemClick 方法工作，但我不能这样做。下面是code其中的 onItemClick 方法不起作用。有没有人有想法，为什么它不工作？

I am working in an Android app where I need to create onItemClick method,but I fail to do so. Below is the code where the onItemClick method does not work. Does anyone have idea why it does not work?

public class sample extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.live_chat_screen);

        mListview = (ListView) findViewById(R.id.mLiveview);
        mListview.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapters, View childView,int position, long arg3) {
                // TODO Auto-generated method stub
                Toast.makeText(sample.this,"Item number : " + position + " clicked",Toast.LENGTH_LONG).show();
            }
        });

下面是XML：

<ListView
     android:id="@+id/mLiveview"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"    
     android:fastScrollEnabled="true"           

     android:scrollbars="vertical" >
</ListView>

其实我已经第一次使用两种观点在我的应用程序是当应用程序打开，另一种观点认为是开放的，而列表视图越来越负载。

Actually I have used two views in my app first is when the app is open and the another view is open while the listview is getting load.

有人能帮助我。

推荐答案

您没有在您的活动设置布局。首先使用设置你的XML 的setContentView（）是这样的：

You are not setting your layout in your activity. First set your xml using setContentView() like this:

setContentView(R.layout.your_xml);

然后继续

mListview = (ListView) findViewById(R.id.mLiveview);
