android:获取手机号码和姓名实现通讯录

首先是运行结果

由于通讯录在手机里是以数据库贮存的 所以我们可以通过一个方法

 context.getContentResolver().query(Phone.CONTENT_URI,null, null, null, null);

来获得通讯录 ,这个方法返回一个游标的数据类型，通过moveToNext()方法来获取所有的手机号码信息

当然读取手机通讯录需要权限 在adnroidManifest文件中声明即可

由于我也实现了打电话的功能 所以也要声明权限

<uses-permission android:name="android.permission.READ_CONTACTS" /><uses-permission android:name="android.permission.CALL_PHONE"/>

布局文件

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/listView1"        android:layout_width="match_parent"        android:layout_height="wrap_content" >    </ListView></RelativeLayout>

listview的布局文件：item.xml，在这里我设置的头像为默认的 当然也可以在手机数据库中读取联系人的icon

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <ImageView        android:id="@+id/image"        android:layout_width="60dp"        android:layout_height="60dp"        android:padding="10dp"        android:src="@drawable/ic_launcher" />    <TextView        android:id="@+id/name"        android:paddingTop="10dp"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_toRightOf="@id/image"        android:text="name" />    <TextView        android:id="@+id/number"        android:paddingTop="5dp"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_below="@id/name"        android:layout_toRightOf="@id/image"        android:text="number" /></RelativeLayout>

自己封装一个联系人信息的类 有两个变量

package com.example.getphonenumber;public class PhoneInfo {private String name;private String number;public PhoneInfo(String name, String number) {this.name = name;this.number = number;}public String getName() {return name;}public String getNumber() {return number;}}

读取手机数据库中的通讯录

GetPhoneNumberFromMobile.class

package com.example.getphonenumber;import java.util.ArrayList;import java.util.List;import android.content.Context;import android.database.Cursor;import android.provider.ContactsContract.CommonDataKinds.Phone;public class GetPhoneNumberFromMobile {private List<PhoneInfo> list;public List<PhoneInfo> getPhoneNumberFromMobile(Context context) {// TODO Auto-generated constructor stublist = new ArrayList<PhoneInfo>();Cursor cursor = context.getContentResolver().query(Phone.CONTENT_URI,null, null, null, null);//moveToNext方法返回的是一个boolean类型的数据 while (cursor.moveToNext()) {//读取通讯录的姓名String name = cursor.getString(cursor.getColumnIndex(Phone.DISPLAY_NAME));//读取通讯录的号码String number = cursor.getString(cursor.getColumnIndex(Phone.NUMBER));PhoneInfo phoneInfo = new PhoneInfo(name, number);list.add(phoneInfo);}return list;}}

自定义adapter

package com.example.getphonenumber;import java.util.ArrayList;import java.util.List;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;public class MyAdapter extends BaseAdapter{private List<PhoneInfo> list;private Context context;public MyAdapter(List<PhoneInfo> list, Context context) {this.list = list;this.context = context;}@Overridepublic int getCount() {// TODO Auto-generated method stubreturn list.size();}@Overridepublic Object getItem(int position) {// TODO Auto-generated method stubreturn list.get(position);}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubif(convertView==null){ViewHolder viewHolder=new ViewHolder();LayoutInflater inflater=LayoutInflater.from(context);convertView=inflater.inflate(R.layout.item, null);viewHolder.name=(TextView) convertView.findViewById(R.id.name);viewHolder.number=(TextView) convertView.findViewById(R.id.number);viewHolder.name.setText(list.get(position).getName());viewHolder.number.setText(list.get(position).getNumber());}return convertView;}public class ViewHolder{TextView name;TextView number;}}

MainActivity中listview加载适配器 并为其添加点击监听事件

package com.example.getphonenumber;import java.util.ArrayList;import java.util.List;import android.net.Uri;import android.os.Bundle;import android.app.Activity;import android.content.Intent;import android.view.Menu;import android.view.View;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.ListView;import android.widget.Toast;public class MainActivity extends Activity implements OnItemClickListener {private ListView lv;private MyAdapter adapter;private GetPhoneNumberFromMobile getPhoneNumberFromMobile;private List<PhoneInfo> list = new ArrayList<PhoneInfo>();protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);lv = (ListView) findViewById(R.id.listView1);getPhoneNumberFromMobile = new GetPhoneNumberFromMobile();list = getPhoneNumberFromMobile.getPhoneNumberFromMobile(this);adapter = new MyAdapter(list, this);lv.setAdapter(adapter);lv.setOnItemClickListener(this);}@Overridepublic void onItemClick(AdapterView<?> parent, View view, int position,long id) {// TODO Auto-generated method stubString number = list.get(position).getNumber();Intent intent = new Intent();intent.setAction("android.intent.action.CALL");intent.addCategory(Intent.CATEGORY_DEFAULT);intent.setData(Uri.parse("tel:"+number));startActivity(intent);}}
