Question

我使用Place API for Android尝试使用Places.PlaceDetectionApi.getCurrentPlace（）来附近的地方。

然而，当我运行应用程序并尝试到附近的地方时，我总是没有结果。

我确信我已设置了“ACCESS_FINE_LOCATION”权限，并启用了“Google Place API”，并设置了相应的API_KEY。

以下是我使用的活动。

public class PlaceLikelihoodActivity extends Activity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {

private GoogleApiClient mGoogleApiClient;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_place_likelihood);

    mGoogleApiClient = new GoogleApiClient
            .Builder(this)
            .addApi(LocationServices.API)
            .addApi(Places.GEO_DATA_API)
            .addApi(Places.PLACE_DETECTION_API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();
}

//function triggered by a button to get nearby places
public void onPlaceLikelihood(View view) {
    Log.i("Place", "onPlaceLikelihood");
    if (mGoogleApiClient != null) {

        PendingResult<PlaceLikelihoodBuffer> result = Places.PlaceDetectionApi
                .getCurrentPlace(mGoogleApiClient, null);

        result.setResultCallback(new ResultCallback<PlaceLikelihoodBuffer>() {
            @Override
            public void onResult(PlaceLikelihoodBuffer likelyPlaces) {
                Log.i("Place", "onResult");
                if (likelyPlaces.getCount() <= 0) {
                    Toast.makeText(PlaceLikelihoodActivity.this, "No place found", Toast.LENGTH_SHORT).show();
                }
                for (PlaceLikelihood placeLikelihood : likelyPlaces) {
                    Log.i("Place", String.format("Place '%s' has likelihood: %g",
                            placeLikelihood.getPlace().getName(),
                            placeLikelihood.getLikelihood()));
                }
                likelyPlaces.release();
            }
        });
    }
    else{
        Toast.makeText(PlaceLikelihoodActivity.this, "No GoogleApiClient", Toast.LENGTH_SHORT).show();
    }

}


@Override
protected void onStart() {
    super.onStart();
    mGoogleApiClient.connect();
}

@Override
protected void onStop() {
    mGoogleApiClient.disconnect();
    super.onStop();
}

@Override
public void onConnected(Bundle bundle) {
    Toast.makeText(this, "onConnected", Toast.LENGTH_LONG).show();

}

@Override
public void onConnectionSuspended(int i) {
    Toast.makeText(this, "onConnectionSuspended", Toast.LENGTH_LONG).show();
}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
    Toast.makeText(this, "onConnectionFailed", Toast.LENGTH_LONG).show();
}
}

Answer 1

Try calling mGoogleApiClient.connect(); in the onCreate method. and maybe check mGoogleApiClient.isConnected() in addition to mGoogleApiClient != null in onPlaceLikelihood.

Answer 2

您是否启用了API＆＃34; Google Places API for Android＆＃34;来自Google Developer Console？侨

Answer 3

我想我知道答案，在模拟器或手机上，保护隐私和安全，并打开位置高精度模式。

Android Place API：PlaceDetectionApi.getCurrentPlace（）始终不返回任何结果
