xamarin.android - 放置自动完成预测

Question

我没有得到任何回应。我错过了什么？谁能给我一个想法。有错误。

        IPlacesClient placesClient = PlacesApi.CreateClient(CrossCurrentActivity.Current.Activity);
        PlacesApi.Initialize(CrossCurrentActivity.Current.Activity, "********API KEY***************");  
        var token = AutocompleteSessionToken.NewInstance();
        var request = FindAutocompletePredictionsRequest.InvokeBuilder()
            .SetSessionToken(token)
            .SetTypeFilter(TypeFilter.Establishment)
            .SetCountry("US")
            .SetQuery("Ind")
            .Build();
        Task<FindAutocompletePredictionsResponse> task = placesClient.FindAutocompletePredictions(request);

可以参考https://github.com/xamarin/XamarinComponents/blob/master/Android/GooglePlaces/samples/PlacesSample/MainActivity.cs

你是在正确的方式。您必须将操作添加到您的任务中。

task.AddOnSuccessListener(CrossCurrentActivity.Current.Activity, this);
task.AddOnFailureListener(CrossCurrentActivity.Current.Activity, this);

然后，将代码添加到每个操作

public void OnSuccess(Java.Lang.Object result)
{
  //Do something
}
public void OnFailure(Java.Lang.Exception e)
{
  //Failed
}

记得实现 IOnSuccessListener、 IOnFailureListener 和 IOnCompleteListener
