java-Places.GeoDataApi.getAutocompletePredictions

我在使用Android Google Places API时遇到问题-自动完成功能.

我正在尝试使用Places.GeoDataApi.getAutocompletePredictions()方法获取placeId,但是,它不起作用.(输出甚至不显示“无法获取值”)
有人可以帮我吗？

这是我的Java代码：

 PendingResult<AutocompletePredictionBuffer> result =
            Places.GeoDataApi.getAutocompletePredictions(mGoogleApiClient, query,
                    mLatLonBounds, null);

    result.setResultCallback(new ResultCallback<AutocompletePredictionBuffer>() {
        @Override
        public void onResult(@NonNull AutocompletePredictionBuffer autocompletePredictions) {

            if (autocompletePredictions.getStatus().isSuccess()) { //如果回傳SUCCESS

                Iterator<AutocompletePrediction> iterator = autocompletePredictions.iterator();
                resultList = new ArrayList<>(autocompletePredictions.getCount());

                while (iterator.hasNext()) {
                    AutocompletePrediction prediction = iterator.next();
                    resultList.add(prediction.getPlaceId().toString());
                }
            }
           else {
                resultList.add("can't get the vaule");
            }
            autocompletePredictions.release();
        }

    });

 textView.setText(resultList.get(0).toString());

谢谢.

解决方法:

我遇到了同样的问题,请按照以下步骤操作

>在开发人员控制台中启用Android版Google Places API,并
在凭证页面上检查您的密钥仍然存在.
>将所需的库添加到模块(play-services-places：11.2.0).
>使用以下代码获取预测

Task<AutocompletePredictionBufferResponse> results = mGeoDataClient.getAutocompletePredictions(yourInputString, yourLatLngBounds, yourTypeFilter);

>添加成功侦听器以进行以下预测

results.addOnSuccessListener(new OnSuccessListener<AutocompletePredictionBufferResponse>() {

@Override
public void onSuccess(AutocompletePredictionBufferResponse autocompletePredictions) {
    Iterator<AutocompletePrediction> iterator = autocompletePredictions.iterator();
    suggesstions = new ArrayList<String>(autocompletePredictions.getCount());
    if (iterator.hasNext()) {
        while (iterator.hasNext()) {
            AutocompletePrediction prediction = iterator.next();
            //do your stuff with prediction here
        }
    }else {
      //Nothing matches...
    }
    autocompletePredictions.release();
}
});

>添加故障侦听器以进行以下预测

results.addOnFailureListener(new OnFailureListener() {
  @Override
  public void onFailure(@NonNull Exception e) {
          Toast.makeText(MapsActivity.this,"Error while fetching suggessions : "+e.getLocalizedMessage(),Toast.LENGTH_SHORT).show();
  }

});

如果以上所有代码段均已正确放置,则您可能需要检查Internet连接.

希望以上代码对您有所帮助.

谢谢.
