Java Android ListView-打开每个项目的新活动

嗨，我正在尝试让我的listview打开每个部分的不同活动。到目前为止，我可以打开一个活动，但是它们都打开相同的活动。我需要知道如何改变这一点，例如：

item1将打开activity1 item2将打开activity2等等

任何帮助都将不胜感激，以下是我的代码（一些评论来自我遵循的教程，非常抱歉我缺乏经验）：

ListView-ListView；
@凌驾
创建时受保护的void（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）；
setContentView（R.layout.activity_about）；
//从xml获取listview
listView=（listView）findViewById（R.id.listView）；
//要在listview中显示的已定义数组
字符串[]值=新字符串[]{“关于应用”，
“如何使用”，
“生成日志”，
};
//定义新的上下文
//第一个参数-上下文
//第二个参数-行的布局
//第三个参数-写入数据的TextView的ID
//第四，数据数组
ArrayAdapteradapter=新的ArrayAdapter（此，
android.R.layout.simple_list_item_1，android.R.id.text1，值）；
//将适配器分配给listview
setAdapter（适配器）；
//ListView项目单击侦听器
setOnItemClickListener（新的AdapterView.OnItemClickListener（）{
@凌驾
public void onItemClick（AdapterView父对象、视图、整型位置、长id）{
/*//listview单击的项目索引
int itemPosition=位置；
//Listview单击的项目值
String itemValue=（String）listView.getItemAtPosition（position）；
//显示警惕
Toast.makeText（getApplicationContext（），
位置：“+itemPosition+”列表项：“+itemValue，Toast.LENGTH_LONG）.show（）*/
Intent appInfo=新Intent（About.this，About_app.class）；
星触觉（appInfo）；
}
});
}

对于这一点，您必须提到：

if (position == 1) {
Intent appInfo = new Intent(About.this, about_app.class);
startActivity(appInfo);
}
else if (position == 2) {
Intent appInfo1 = new Intent(About.this, Test.class);
startActivity(appInfo1);
}

listView.setOnItemClickListener（新的AdapterView.OnItemClickListener（）{
@凌驾
public void onItemClick（AdapterView父对象、视图、整型位置、长id）{
/*//listview单击的项目索引
int itemPosition=位置；
//Listview单击的项目值
String itemValue=（String）listView.getItemAtPosition（position）；
//显示警惕
Toast.makeText（getApplicationContext（），
位置：“+itemPosition+”列表项：“+itemValue，Toast.LENGTH_LONG）.show（）*/
开关（位置）
案例0:Intent appInfo=新Intent（About.this，About_app.class）；
星触觉（appInfo）；
打破
案例1:Intent appInfo=新Intent（About.this，Activity1.class）；
星触觉（appInfo）；
打破
案例2:Intent appInfo=新Intent（About.this，Activity2.class）；
星触觉（appInfo）；
打破
}
});
