代码如下:

public class AndroidDemoActivity extends Activity{

public void onCreate(Bundle savedInstanceState) {
TextView tv = new TextView(this);
String string = "";
super.onCreate(savedInstanceState);
//得到ContentResolver对象
ContentResolver cr = getContentResolver();
//取得电话本中开始一项的光标
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
//向下移动光标
while(cursor.moveToNext()){
//取得联系人名字
int nameFieldColumnIndex = cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = cursor.getString(nameFieldColumnIndex);
//取得电话号码
String ContactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactId, null, null);
while(phone.moveToNext()){
String PhoneNumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
string += (contact + ":" + PhoneNumber + "/n");
}
}
cursor.close();
//设置TextView显示的内容
tv.setText(string);
//显示到屏幕
setContentView(tv);
}

}

注意的是：这个获取的时间有点长，所以这个过程最好放到子线程中执行！
