适用于Android的Google Places API-为城市获取0张照片

Question

I am using Google places API for android to let the user select cities in the world. Then I use the placeId to get an image to something similar to google maps.

Picture example

Every single time I'm getting the photos bundle successfully but it contains no images. It works just fine if I use the placeId of any restaurant or cafe or any other single spot but not for a whole city.

Here's the method I'm using to get the images.

public void loadPlaceImage(final ImageView imageView, String placeId) {

    /**
     * Load a bitmap from the photos API asynchronously
     * by using buffers and result callbacks.
     */

    Places.GeoDataApi.getPlacePhotos(mGoogleApiClient, placeId)
            .setResultCallback(new ResultCallback<PlacePhotoMetadataResult>() {


                @Override
                public void onResult(PlacePhotoMetadataResult photos) {
                    if (!photos.getStatus().isSuccess()) {
                        Log.d(TAG, "Couldn\'t receive photos bundle successfully.");
                        return;
                    }

                    Log.d(TAG, "Photo bundle received successfully");

                    PlacePhotoMetadataBuffer photoMetadataBuffer = photos.getPhotoMetadata();
                    if (photoMetadataBuffer.getCount() > 0) {
                        // Display the first bitmap in an ImageView in the size of the view
                        photoMetadataBuffer.get(0)
                                .getScaledPhoto(mGoogleApiClient, imageView.getWidth(),
                                        imageView.getHeight())
                                .setResultCallback(new ResultCallback<PlacePhotoResult>() {
                                    @Override
                                    public void onResult(PlacePhotoResult placePhotoResult) {
                                        if (!placePhotoResult.getStatus().isSuccess()) {
                                            Log.d(TAG, "Couldn\'t retrieve the photo successfully.");
                                            return;
                                        }

                                        Log.d(TAG, "Successfully retrieved photo from photo bundle.");

                                        imageView.setImageBitmap(placePhotoResult.getBitmap());
                                    }
                                });
                    } else {
                        Log.d(TAG, "0 images in the buffer.");
                    }
                    photoMetadataBuffer.release();
                }
            });

}

I used your code in my android studio, it hadn't problem in your code.

I guess you forgot to add meta-data in Manifest.

  <application
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>

    <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="YOURKEY"/>
</application>

it is for reference to set up your "Android KEY"
https://developers.google.com/places/android-api/signup

https://console.developers.google.com/apis (this Link can set your key)

By the way, you can use:

Log.d(TAG,"result getStatus "+result.getStatus().getStatus());

to check your error message, hope it will help you
