android - ListView 的 setOnClickListener 不起作用

Question

所以我试图为我的 ListView 设置一个 setOnClickListener 但是当我尝试时由于某种原因它导致我的程序崩溃......我是对编程很陌生，所以当涉及到故障排除时，我真的无能为力:(我的代码在下面，所以任何关于可能出错的想法都会非常有帮助:

public class HomePageActivity extends Activity {
    //ListView that holds the items
    ListView lstTest;
    
    //Array Adapter that holds the ArrayList and displays the items on the ListView
    AlertsAdapter arrayAdapter;
    
    //List that hosts the items
    ArrayList<Alerts> alrts = null;
    
    /** Called when the activity is first created. */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.homepage);
        
        //Initialize the ListView
        lstTest = (ListView)findViewById(R.id.lstText);
        
        //Initialize the ArrayList
        alrts = new ArrayList&lt;Alerts&gt;();
        
        //Initialize the array adapter
        arrayAdapter = new AlertsAdapter(HomePageActivity.this, R.layout.listitems,alrts);
        
        //Set the above adapter as the adapter of choice for our list
        lstTest.setAdapter(arrayAdapter);
        
        lstTest.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Intent intent = new Intent(
                HomePageActivity.this,
                PromotionActivity.class
                );
                startActivity(intent);
            }
        });
        //... ... ...
    }
} 

有什么想法吗？我被卡住了:(

我看到它说我可能想要 setOnItemClickListener，这就是我最初编写的代码，但它无法正常工作，因为 eclipse 告诉我我的代码有问题。

Answer 1

你需要使用setOnItemClickListener()

然后new android.widget.AdapterView.OnItemClickListener()

不是new View.OnItemClickListener()
