有人可以给我一个删除所有ListView项目并替换为新项目的示例代码吗？

我尝试更换适配器项而没有成功.我的代码是

populateList(){

 results //populated arraylist with strings

 ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, results);

 listview.setAdapter(adapter);
 adapter.notifyDataSetChanged();
 listview.setOnItemClickListener(this);

}

// now populating list again

repopulateList(){

 results1 //populated arraylist with strings

 ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, results1);

 listview.setAdapter(adapter1);
 adapter1.notifyDataSetChanged();
 listview.setOnItemClickListener(this);
}

这里的repopulateList()方法将添加到ListView项,但它不会删除/替换所有ListView项.
