Android开发读取通讯录信息

需求
通过搜索联系人的姓名获取相应的详细人信息，也可通过右侧字母条搜索相应的联系人信息。
主要代码如下：
MainActivity

public class MainActivity extends AppCompatActivity {private ListView sortListView;private SideLetterUtil sideLetterUtil;private TextView dialog;private SortAdapter adapter;private ClearEditText mClearEditText;private String mobile,//被授权人电话号码name;//被授权人姓名/*** 查询通讯录名字*/private Uri contactsUrl = ContactsContract.Contacts.CONTENT_URI;private ContentResolver resolver;private List<ContactsBean> nameList;/*** 汉字转换成拼音的类*/private CharacterParser characterParser;private List<ContactsBean> SourceDateList;/*** 根据拼音来排列ListView里面的数据类*/private ContactsPinyinComparator pinyinComparator;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);getPersimmionInfo();}private void getPersimmionInfo() {if (Build.VERSION.SDK_INT >= 23) {//1. 检测是否添加权限   PERMISSION_GRANTED  表示已经授权并可以使用if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {//手机为Android6.0的版本,权限未授权去i请授权//2. 申请请求授权权限//1.
