1.在AndroidManifest.xml设置访问通讯的权限：

//添加访问通讯录的权限

2.模拟获取通讯录的名称与电话号码，然后用ListView进行显示，现在xml文件中添加ListView，

android:id="@+id/contact_listview"

android:layout_width="match_parent"

android:layout_height="match_parent"

>

3.在Activity中，配置ListView(核心代码)

private ListView listView;

private ArrayAdapter adapter; //适配器

List contactList = new ArrayList(); //通讯获取的数据

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

listView = (ListView)findViewById(R.id.contact_listview);

adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, contactList);

listView.setAdapter(adapter);

/*获取通讯录数据

* 1.先判断是否已经有读取通讯录的权限

* 2.如果没有的话，询问用户，如果有的话，直接读取通讯录的数据*/

//1

if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED ) {

//未获得权限，询问用户

ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CONTACTS}, 1);

} else {

//已经权限

readContacts();

}

}

//读取通讯录数据

public void readContacts() {

Cursor contactCursor = null;

try {

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

if ( contactCursor != null ) {

while (contactCursor.moveToNext()) {

//读取通讯录数据

String name = contactCursor.getString(contactCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));

String phoneNumber = contactCursor.getString(contactCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

contactList.add(name + "

" + phoneNumber);

}

adapter.notifyDataSetChanged(); //刷新ListView

}

}catch ( SecurityException e) {

e.printStackTrace();

}

}

//权限选择结果回调

@Override

public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

switch (requestCode) {

case 1:

{

if ( grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED ) {

readContacts();

} else {

Toast.makeText(this, "你不能读取用户通讯录", Toast.LENGTH_SHORT).show();

}

}

break;

default:

break;

}

}

ok
