Android 中的电话选择器 api

我正在尝试使用电话选择器 API 获取电话号码，但得到空响应，这是我的代码。

GoogleApiClient googleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Auth.CREDENTIALS_API)
            .addConnectionCallbacks(this) 
            .addOnConnectionFailedListener(this) 
            .build();
    googleApiClient.connect();

HintRequest hintRequest = new HintRequest.Builder()
            .setPhoneNumberIdentifierSupported(true)
            .build();

    PendingIntent intent = Auth.CredentialsApi.getHintPickerIntent(
            googleApiClient, hintRequest);
    try {
        startIntentSenderForResult(intent.getIntentSender(),
                RESOLVE_HINT, null, 0, 0, 0);
    } catch (IntentSender.SendIntentException e) {
        e.printStackTrace();
    }

 @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RESOLVE_HINT) {
        if (resultCode == RESULT_OK) {
            Credential credential = data.getParcelableExtra(Credential.EXTRA_KEY);
            // credential.getId();  <-- will need to process phone number string

        }
    }
}

上面的 resultCode 总是返回 0。

这是我为获取号码所做的事情：

Note:我正在获取里面的数字Fragment.

1）获取GoogleApiClient

private void getCreadenticalApiClient() {
        mCredentialsApiClient = new GoogleApiClient.Builder(getBaseContext())
                .addConnectionCallbacks(this)
                .enableAutoManage(getBaseContext(), this)
                .addApi(Auth.CREDENTIALS_API)
                .build();
    }

2）showHint方法将显示弹出的数字：

private void showHint() {
        HintRequest hintRequest = new HintRequest.Builder()
                .setHintPickerConfig(new CredentialPickerConfig.Builder()
                        .setShowCancelButton(true)
                        .build())
                .setPhoneNumberIdentifierSupported(true)
                .build();

        PendingIntent intent =
                Auth.CredentialsApi.getHintPickerIntent(mCredentialsApiClient, hintRequest);
        try {
            startIntentSenderForResult(intent.getIntentSender(), RC_HINT, null, 0, 0, 0,new Bundle());
        } catch (IntentSender.SendIntentException e) {
            Log.e("Login", "Could not start hint picker Intent", e);
        }
    }

3）这是您为View分配编号的地方

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RC_HINT) {
            if (resultCode == RESULT_OK) {
                Credential cred = data.getParcelableExtra(Credential.EXTRA_KEY);
                etMobile.setText(cred.getId().substring(3));
            }
        }
    }

最后不要忘记在片段中实现这两个接口：

GoogleApiClient.ConnectionCallbacks
GoogleApiClient.OnConnectionFailedListener

依赖项：
