ListViewの各エントリはどのようにして別のActivityにジャンプしますか?

<span style="font-size:18px;"><span style="color:#33cc00;"> </span>public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.group);
         
        listView=(ListView)findViewById(R.id.group1_list);
        listItems=getlistItems();
        listViewAdapter=new ListViewAdapter(this, listItems);
        listView.setAdapter(listViewAdapter);
        listView.setTextFilterEnabled(true);
         
        listView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,long id) {
                Log.i("mm", " onItemClick ");
                Intent intent=new Intent();
                switch(position){
                case 0:
                    intent.setClass(getApplicationContext(), ListViewGroup.class);
                    GroupActivity.this.startActivity(intent);
                    break;
                case 1:
                    intent.setClass(getApplicationContext(), ListViewGroup.class);
                    GroupActivity.this.startActivity(intent);
                    break;
                case 2:
                    intent.setClass(getApplicationContext(), ListViewGroup.class);
                    GroupActivity.this.startActivity(intent);
                    break;
}
}
});
}</span>
