本文介绍如何在Android应用中使用ListView组件。通过示例展示了如何创建一个包含大量条目的ListView，并为每个条目设置点击事件来显示对应的数据。

ListView:先在XML写一个高级控件ListView

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ListView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/lv_list_names"
        ></ListView>


</LinearLayout>

然后去Activity写如下代码:

package com.zking.g160628_android07_widgetplus;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

import java.util.ArrayList;
import java.util.List;

public class ListActivity extends AppCompatActivity {

    private ListView lv_list_names;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_list);
        lv_list_names = (ListView) findViewById(R.id.lv_list_names);

        final List<String> names=new ArrayList<>();
        for (int i = 0; i <100; i++) {
            names.add("张"+i);
        }

        ArrayAdapter adapter=new ArrayAdapter(this,android.R.layout.simple_list_item_1,names);

        lv_list_names.setAdapter(adapter);

        //给ListView设置点击事件
        lv_list_names.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                Toast.makeText(ListActivity.this, names.get(i), Toast.LENGTH_SHORT).show();
            }
        });
    }
}
