设置ListView无数据的时候显示TextView暂无数据

在ListView列表中，如果没有数据的时候进行友好的文字提示。

package com.example.lixiangjian.myapplication; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.AdapterView; import android.widget.ListView; import android.widget.TextView; import java.util.ArrayList; import java.util.List; public class MainActivity extends AppCompatActivity { private ListView listView; private TextView text_tip; private List<Bean> list; private MyAdapter adapter; @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); text_tip = (TextView) findViewById(R.id.text_tip); } private void initData() { list = new ArrayList<>(); for (int i = 0; i < 20; i++) { list.add(new Bean("张三" + i, "账号：" + i)); } } }

当点击删除item的删除完所有数据后会显示“暂无数据”
