Android-尝试使用mGeoDataClient.getPlaceById（id）从任务获取PlaceBufferResponse，但失败

我试着用Android studio在Android中使用谷歌的GeoDataClient获取一个地方的信息。 具体地说，我已经设置了一个OnPoickListener，因此当单击一个关注点时，会显示一个标记，并显示一个信息窗口来显示详细信息。为了获得详细信息，我使用了GeoDataClient的getPlaceById（id）方法。如下图所示：

Task<PlaceBufferResponse> placeBufferResponseTask = mGeoDataClient.getPlaceById(mPlaceId);
placeBufferResponseTask.addOnCompleteListener(new OnCompleteListener<PlaceBufferResponse>() {
    @Override
    public void onComplete(@NonNull Task<PlaceBufferResponse> task) {
        try {
            PlaceBufferResponse bufferResponse = task.getResult();
            final Place resultPlace = bufferResponse.get(0);

            placeName.setText(resultPlace.getName());
            placeType.setText(resultPlace.getPlaceTypes().get(0));
            placeAddress.setText(resultPlace.getAddress());


            bufferResponse.release();
            } catch (RuntimeException e) {
                Log.e(TAG, "Place query did not complete.", e);
            }
        }

从代码中。有人能帮忙吗？非常感谢

您正在使用以下语句从后台线程修改UI：

placeName.setText(resultPlace.getName());
placeType.setText(resultPlace.getPlaceTypes().get(0));
placeAddress.setText(resultPlace.getAddress());

如果要执行此操作，需要使用处理程序将修改操作排队到UI线程，完整代码如下所示：

placeBufferResponseTask.addOnCompleteListener(new OnCompleteListener<PlaceBufferResponse>() {
        @Override
        public void onComplete(@NonNull Task<PlaceBufferResponse> task) {
            try {
                PlaceBufferResponse bufferResponse = task.getResult();
                final Place resultPlace = bufferResponse.get(0);

                Handler mainHandler = new Handler(Looper.getMainLooper());

                Runnable myRunnable = new Runnable() {
                    @Override
                    public void run() {
                        placeName.setText(resultPlace.getName());
                        placeType.setText(resultPlace.getPlaceTypes().get(0));
                        placeAddress.setText(resultPlace.getAddress());
                    }
                };
                mainHandler.post(myRunnable);

                bufferResponse.release();
            } catch (RuntimeException e) {
                Log.e(TAG, "Place query did not complete.", e);
            }

    }

placeBufferResponseTask.addOnCompleteListener（新的OnCompleteListener（）{
@凌驾
未完成的公共void（@NonNull任务）{
试一试{
PlaceBufferResponse=task.getResult（）；
最终位置resultPlace=bufferResponse.get（0）；
Handler mainHandler=新处理程序（Looper.getMainLooper（））；
Runnable myRunnable=新Runnable（）{
@凌驾
公开募捐{
placeName.setText（resultPlace.getName（））；
placeType.setText（resultPlace.getPlaceTypes（）.get（0））；
placeAddress.setText（resultPlace.getAddress（））；
}
};
mainHandler.post（myRunnable）；
bufferResponse.release（）；
}捕获（运行时异常e）{
Log.e（标记“位置查询未完成”，e）；
}
}

或者您可以使用的方法

runOnUiThread

of.

非常感谢，我刚刚用您的解决方案使它工作了！

placeBufferResponseTask.addOnCompleteListener(new OnCompleteListener<PlaceBufferResponse>() {
        @Override
        public void onComplete(@NonNull Task<PlaceBufferResponse> task) {
            try {
                PlaceBufferResponse bufferResponse = task.getResult();
                final Place resultPlace = bufferResponse.get(0);

                Handler mainHandler = new Handler(Looper.getMainLooper());

                Runnable myRunnable = new Runnable() {
                    @Override
                    public void run() {
                        placeName.setText(resultPlace.getName());
                        placeType.setText(resultPlace.getPlaceTypes().get(0));
                        placeAddress.setText(resultPlace.getAddress());
                    }
                };
                mainHandler.post(myRunnable);

                bufferResponse.release();
            } catch (RuntimeException e) {
                Log.e(TAG, "Place query did not complete.", e);
            }

    }
