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;/** * @author Zking-Snail * @time 2017/6/8 11:18 * @Version ${REV} */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();            }        });    }}
