首先给大家展示下运行效果图：

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"></uses-permission></uses-permission>

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


<!--{cke_protected}{C}%3C!%2D%2D%3Fxml%20version%3D%221.0%22%20encoding%3D%22utf-8%22%3F%2D%2D%3E-->
<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">
</textview></textview></imageview></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 stub
list = 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;
}
}</phoneinfo></phoneinfo></phoneinfo>

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;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return list.get(position);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
if(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;
}
}</phoneinfo></phoneinfo>

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);
}
@Override
public void onItemClick(AdapterView<!--?--> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
String 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);
}
}</phoneinfo></phoneinfo>
