因此,我尝试为自己的setOnClickListener
设置ListView
,但是由于某些原因,它导致我的程序崩溃...我对编程很陌生,因此在进行故障排除时我什么也做不了可悲的是:(我的代码在下面,所以任何关于可能出错的想法都将非常有帮助:
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<Alerts>();
//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
,它原来是我编写的代码,但是由于eclipse告诉我我的代码不对,所以它不起作用。 最佳答案
您需要使用setOnItemClickListener()
然后new android.widget.AdapterView.OnItemClickListener()
不是new View.OnItemClickListener()
