Android ListView在单击项目时打开活动？

我正在尝试构建这个应用程序，它由一个ListView和其他不同的活动组成，当点击视图中的一个项目时，这些活动将被调用。但是，我无法在主活动中实现工作onclicklistener。使用下面的代码，我无法打开活动

代码如下：

public void setOnItemClickListener(AdapterView<?> parent, View view,
      int position, long id) {
    switch( position )
    {
       case 0:  Intent newActivity0 = new Intent(this, TempuraActivity.class);     
                startActivity(newActivity0);
                break;
       case 1:  Intent newActivity1 = new Intent(this, TempuraActivity.class);     
                startActivity(newActivity1);
                break;
       case 2:  Intent newActivity2 = new Intent(this, TempuraActivity.class);     
                startActivity(newActivity2);
                break;
       case 3:  Intent newActivity3 = new Intent(this, TempuraActivity.class);     
                startActivity(newActivity3);
                break;
       case 4:  Intent newActivity4 = new Intent(this, TempuraActivity.class);     
                startActivity(newActivity4);
                break;
    }
}

public void setOnItemClickListener（AdapterView父视图、视图、，
内部位置，长id）{
开关（位置）
{
案例0:Intent newActivity0=新Intent（这是TempuraActivity.class）；
startActivity（newActivity0）；
打破
案例1:Intent newActivity1=新Intent（this，TempuraActivity.class）；
startActivity（新活动1）；
打破
案例2:Intent newActivity2=新Intent（this，TempuraActivity.class）；
startActivity（新活动2）；
打破
案例3:Intent newActivity3=新Intent（this，TempuraActivity.class）；
startActivity（新活动3）；
打破
案例4:Intent newActivity4=新Intent（this，TempuraActivity.class）；
startActivity（新活动4）；
打破
}
}

任何帮助将不胜感激：）评论如果你需要看到完整的代码，我会在帖子中更新。谢谢

您的代码有点混乱，存在一个对象，但实际上需要将该方法传递给一个对象（或匿名类）

也许您正在ListActivity中寻找类似的内容

final ListView listView = getListView();
listView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> paramAdapterView, View paramView, int paramInt,
            long paramLong) {
        switch( position )
{
   case 0:  Intent newActivity0 = new Intent(YourActivity.this, TempuraActivity.class);     
            startActivity(newActivity0);
            break;
   case 1:  Intent newActivity1 = new Intent(YourActivity.this, TempuraActivity.class);     
            startActivity(newActivity1);
            break;
   case 2:  Intent newActivity2 = new Intent(YourActivity.this, TempuraActivity.class);     
            startActivity(newActivity2);
            break;
   case 3:  Intent newActivity3 = new Intent(YourActivity.this, TempuraActivity.class);     
            startActivity(newActivity3);
            break;
   case 4:  Intent newActivity4 = new Intent(YourActivity.this, TempuraActivity.class);     
            startActivity(newActivity4);
            break;
}              
    }
});

在列表活动中，取消对
getListView（）的额外调用
