我需要获取最近24小时内最近使用且最常用的联系人列表。
我进行了很多搜索,但没有找到任何方法。我还知道Google已撤销URI以获取经常使用的联系人:https://developer.android.com/reference/android/provider/ContactsContract.Contacts#CONTENT_FREQUENT_URI
但是没有给出该URI的替代品吗? 请让我知道实现的方法:

public class MainActivity extends AppCompatActivity {
ListView listView ;
ArrayList<String> StoreContacts ;
ArrayAdapter<String> arrayAdapter ;
Cursor cursor ;
String name, phonenumber ;
public static final int RequestPermissionCode = 1 ;
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView)findViewById(R.id.listview1);
button = (Button)findViewById(R.id.button1);
StoreContacts = new ArrayList<String>();
EnableRuntimePermission();
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
GetContactsIntoArrayList();
arrayAdapter = new ArrayAdapter<String>(
MainActivity.this,
R.layout.contact_items_listview,
R.id.textView, StoreContacts

listView.setAdapter(arrayAdapter);

getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,null, null, null);
while (cursor.moveToNext()) {
name =
cursor.getString(cursor.getColumnIndex

E));
phonenumber =
cursor.getString(cursor.getColumnIndex
(ContactsContract.CommonDataKinds.Phone.NUMBER));
StoreContacts.add(name + " " + ":" + " " + phonenumber);
}
cursor.close();
}
public void EnableRuntimePermission(){
if (ActivityCompat.shouldShowRequestPermissionRationale(
MainActivity.this,
Manifest.permission.READ_CONTACTS))
{
Toast.makeText(MainActivity.this,"CONTACTS permission allows us to Access
CONTACTS app", Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(MainActivity.this,new String[]{
Manifest.permission.READ_CONTACTS}, RequestPermissionCode);
}
}
@Override
public void onRequestPermissionsResult(int RC, String per[], int[] PResult) {
switch (RC) {
case RequestPermissionCode:
if (PResult.length > 0 && PResult[0] ==
PackageManager.PERMISSION_GRANTED) {

application can access CONTACTS.", Toast.LENGTH_LONG).show();
} else {

不推荐使用Contacts表中的CONTENT_FREQUENT_URI
以及TIMES_CONTACTED
和LAST_TIME_CONTACTED
字段的全部目的是防止访问您所用的信息正在寻找。
Google现在将此信息视为敏感的用户信息,并且不允许应用程序继续获取该信息。
但是,根据我的经验,似乎我所知道的或我们的用户使用的所有设备仍然允许访问已弃用的API,因此,如果您需要在明年或大多数时间内可以满足大多数用户的需求,因此,您仍然可以使用它。
代码应类似于:
String[] projection = new String[] { Contacts._ID, Contacts.DISPLAY_NAME, Contacts.LAST_TIME_CONTACTED };
Cursor lastContacted = getContentResolver().query(Contacts.CONTENT_URI, projection, Contacts.LAST_TIME_CONTACTED + " < " + lastDayTimestamp, null, Contacts.LAST_TIME_CONTACTED + " DESC");
DatabaseUtils.dumpCursor(lastContacted);
Cursor mostContacted = getContentResolver().query(Contacts.CONTENT_URI, projection, null, null, Contacts.TIMES_CONTACTED + " DESC");
DatabaseUtils.dumpCursor(mostContacted); // might want to limit this to 3
