我的代码有问题 iv 一直在尝试修复此错误，但仍然没有运气。我想在单击列表视图中的项目时开始一个新活动我找了一段时间发现了这个代码
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
switch( position )
{
case 0: Intent newActivity = new Intent(this, superleague.class);
startActivity(newActivity);
break;
case 1: Intent newActivity = new Intent(this, youtube.class);
startActivity(newActivity);
break;
case 2: Intent newActivity = new Intent(this, olympiakos.class);
startActivity(newActivity);
break;
case 3: Intent newActivity = new Intent(this, karaiskaki.class);
startActivity(newActivity);
break;
case 4: Intent newActivity = new Intent(this, reservetickets.class);
startActivity(newActivity);
break;
}
}
现在我把它放在我的项目中，问题出在哪里，但由于我是新手，所以需要一些时间来解决小问题，希望你能提供帮助？
