Android获取电话号码提示

Question

我一直在引用我的教程链接以获取电话号码提示，但是使用的代码已被弃用。

val hintRequest = HintRequest.Builder()
            .setPhoneNumberIdentifierSupported(true)
            .build()

这是我现在正在关注的那个。

ActivityResultLauncher phoneNumberHintIntentResultLauncher =
  registerForActivityResult(
      new ActivityResultContracts.StartActivityForResult(),
      new ActivityResultCallback() {
          @Override
          public void onActivityResult(ActivityResult result) {
              try {
                  String phoneNumber = Identity.getSignInClient(activity).getPhoneNumberFromIntent(result.getData());
              } catch {
                  Log.e(TAG, “Phone Number Hint failed”, e);
              }
          }
  });

对于上述代码，我在Android Studio中获得错误，

Class 'Anonymous class derived from ActivityResultCallback' must either be declared abstract or implement abstract method 'onActivityResult(O)' in 'ActivityResultCallback'

什么是实现电话号码提示的正确方法？

如果使用Java，可以使用此代码，
首先制作一个类似的ActivityResultLauncher：

    ActivityResultLauncher<IntentSenderRequest> phoneNumberHintIntentResultLauncher =
        registerForActivityResult(
                new ActivityResultContracts.StartIntentSenderForResult(), new ActivityResultCallback<ActivityResult>() {
                    @Override
                    public void onActivityResult(ActivityResult result) {
                            try {
                                String phoneNumber = Identity.getSignInClient(getApplicationContext()).getPhoneNumberFromIntent(result.getData());
                                showPhoneNum.setText(phoneNumber);
                            } catch (Exception e) {
                                e.printStackTrace();
                            }
                    }
                });

然后制作一个GetPhoneNumberHintEntEntentRequest对象并遵循此代码：

    GetPhoneNumberHintIntentRequest request = GetPhoneNumberHintIntentRequest.builder().build();

        Identity.getSignInClient(MainActivity.this)
                .getPhoneNumberHintIntent(request)
                .addOnSuccessListener(result -> {
                    try {
                        IntentSender intentSender = result.getIntentSender();
                        phoneNumberHintIntentResultLauncher.launch(new IntentSenderRequest.Builder(intentSender).build());
                    } catch (Exception e) {
                        Log.i("Error launching", "error occurred in launching Activity result");
                    }
                })
                .addOnFailureListener(e -> Log.i("Failure occurred", "Failure getting phone number"));

希望它能有所帮助。
