Android 获取手机联系人信息

protected 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(ContactsContract.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 Number = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
string += (contact + ":" + Number + "\n");//每个联系人后均换行
}
}
cursor.close();
tv.setMovementMethod(new ScrollingMovementMethod());//设置滚动显示
//设置TextView显示的内容
tv.setText(string);
//显示到屏幕
setContentView(tv);
}
}
