如何获取联系人列表

 
 首先先加上权限!
<uses-permission android:name="android.permission.READ_CONTACTS" />

使用代码示例:

 private ListView contactListView;
 private ContactsAdapter adapter;
 private List<Contacts> contactsList = new ArrayList<>();

 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    contactListView = (ListView) findViewById(R.id.listview);
    
      getContacts();
    adapter = new ContactsAdapter(this, contactsList);    contactListView.setAdapter(adapter);  } 

/**  * 获取联系人列表  */

 private void getContacts() {    

Cursor cursor = null;   

 try {        

cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null); 

  while (cursor.moveToNext()) {           

       String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));     

       String number = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));         

       Contacts contacts = new Contacts(displayName, number);        

       contactsList.add(contacts);      

   }  

  } catch (Exception e) {        e.printStackTrace();    

 } finally {       

 if (cursor != null) {           

     cursor.close();     

   }   

 } 

}
