一、添加权限：
<uses-permission android:name="android.permission.READ_CONTACTS" /> 二、item.xml（创建ListView）：
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <LinearLayout android:layout_width="match_parent" android:layout_height="60sp" android:orientation="horizontal" > <TextView android:id="@+id/tv_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:text="1111" android:textSize="35sp" /> <TextView android:id="@+id/tv_number" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom" android:text="2222" android:textSize="25sp" /> LinearLayout>LinearLayout>三、activity_main.xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <ListView android:id="@+id/lv" android:layout_width="match_parent" android:layout_height="match_parent" > ListView>RelativeLayout>四、ListViewAdapter.java(ListView的适配器):
package com.example.listviewshowlianxipeople;import java.util.List;import android.annotation.SuppressLint;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;@SuppressLint("InflateParams")public class ListViewAdapter extends BaseAdapter { List names, phones; LayoutInflater inflater; @SuppressWarnings("static-access") public ListViewAdapter(Context context, List names, List phones) { inflater = inflater.from(context); this.names = names; this.phones = phones; } @Override public int getCount() { return names.size(); } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { View view; if (convertView == null) { view = inflater.inflate(R.layout.item, null); TextView tv_name = (TextView) view.findViewById(R.id.tv_name); TextView tv_phone = (TextView) view.findViewById(R.id.tv_number); tv_name.setText(names.get(position)); tv_phone.setText(phones.get(position)); } else { view = convertView; } return view; }} 五、MainActivity.java:
package com.example.listviewshowlianxipeople;import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.database.Cursor;import android.os.Bundle;import android.provider.ContactsContract;import android.widget.ListView;public class MainActivity extends Activity { ListView lv; List list_phone, list_name; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); lv = (ListView) findViewById(R.id.lv); list_name = new ArrayList(); list_phone = new ArrayList(); Cursor c = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null); //获取通讯录的信息 startManagingCursor(c); int phoneIndex = 0, nameIndex = 0; if (c.getCount() > 0) { phoneIndex = c .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER); // 获取手机号码的列名 nameIndex = c .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME); // 获取用户名的列名 } while (c.moveToNext()) { String phone = c.getString(phoneIndex); // 获取手机号码 list_phone.add(phone); String name = c.getString(nameIndex); // 获取用户名 list_name.add(name); } ListViewAdapter adapter = new ListViewAdapter(this, list_name, list_phone); lv.setAdapter(adapter); }} 代码下载地址：
