转载自：http://blog.csdn.net/llixiangjian/article/details/71599590

用Android studio开发

在ListView列表中，如果没有数据的时候进行友好的文字提示。

    private TextView text_tip;

    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
  
        initView();  
        initData();  
        adapter = new MyAdapter(list, this);  
        listView.setAdapter(adapter);  
        listView.setEmptyView(text_tip);//设置当ListView为空的时候显示text_tip "暂无数据"  
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {  
            @Override  
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {  
                list.remove(position);  
                adapter.notifyDataSetChanged();//在list删除数据的时候 记得要刷新适配器（）  
            }  
        });  
    }  
  
    private void initView() {  
        listView = (ListView) findViewById(R.id.list);

        list = new ArrayList<>();  
        for (int i = 0; i < 20; i++) {  
            list.add(new Bean("张三" + i, "账号：" + i));
