android 实现Listview 动态删除

 ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,list);
 listView.setAdapter(adapter);
 listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    public void onItemClick(AdapterView parent, View view, int position, long id) {
    String item = adapter.getItem(position);
    adapter.remove(item);
    adapter.add("添加一个");
    }
});
