android 通过点击上下文菜单采用intent启动activity

编程小白一枚，如题，如何才能做到，我现在已经在app中添加了浮动的导航菜单，我希望在点击导航菜单的时候启动一个新的activity,但是下面的代码完成不了，请大神看一下。

protectedvoid onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_activity_view);
 
    dataSource = newDBDataSource(this);
 
    dataSource.open();
 
    values = dataSource.getAllMahasiswa();
 
    ArrayAdapter<mahasiswa> adapter = newArrayAdapter<mahasiswa>     (this, android.R.layout.simple_list_item_1, values);
 
    setListAdapter(adapter);
 
    listView=(ListView) findViewById(android.R.id.list);
    registerForContextMenu(listView);
 
 
 
}
publicvoid onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
        super.onCreateContextMenu(menu, v, menuInfo);
 
        menu.add(0,1000,0,"Edit");
        menu.add(0,1001,0,"Hapus");
 
}
 
publicboolean onContextMenuItemSelected(MenuItem item){
     switch(item.getItemId()) {
       case1000:
           Intent i = newIntent(ActivityView.this, Tes.class);
 
           startActivity(i);
       break;
       case1001:
          //not yet
       break;
       }
       returnsuper.onContextItemSelected(item);
 
 }</mahasiswa></mahasiswa>

处理方法

在android开发中共有两种方式完成，使用下面的2代码
代码一
@Override
public boolean onContextItemSelected(MenuItem item)
{
        switch (item.getItemId())
        {
        case R.id.pick_camera:

            break;
        }
    return super.onContextItemSelected(item);
}
代码二
@Override
    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)
    {

         getMenuInflater().inflate(R.menu.image_options, menu);
        super.onCreateContextMenu(menu, v, menuInfo);
    }

在菜单资源路径创建image_options.xml
create image_options.xml in menu folder of resource.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

</menu>
