publicclass Activity01 extends Activity
{
publicvoid 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);
}
}

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

Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +"="+ ContactId, null, null);

Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +"="+ ContactId +" AND "+ ContactsContract.CommonDataKinds.Phone.TYPE +"="+ ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE, null, null);
