Question

我已经在youtube上搜了好几个小时，我似乎无法找到一个有效的。到目前为止，我在我的代码中有这个，但它不会让我开始一个新的活动。

public class MainActivity extends ActionBarActivity {
ArrayList<PerMoney> PeepList = new ArrayList<PerMoney>();
int pos = -1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ListView people = (ListView)findViewById(R.id.peopleList);
    setContentView(R.layout.activity_main);
    if(PeepList.size() != 0)
        UpdateList();
    people.setOnItemClickListener(onListClick);
}

然后是onitemclick部分

private AdapterView.OnClickListener onListClick=new AdapterView.OnItemClickListener()
{
        ListView people = (ListView) findViewById(R.id.peopleList);
        int res;
        people.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override

             public void onItemClick(AdapterView<?> parent, View view, int position, long id) 
             {
                   pos = position;
                   Intent intent = new Intent(this,SecondActivity.class);
                   startActivityForResult(intent, 0);
             }
        };
}

Answer 1

不应该是：

Intent intent = new Intent(MainActivity.this,SecondActivity.class);

如何按项目ListView进行可点击以启动新活动
