我已经开始研究retrolambda 和rxjava。我自己转换了一些表达式，但其中一些我无法转换。我已将 retrolambda 添加到我的项目中。这里是示例

public Observable<ImmutableList<Repository>> getUsersRepositories() {
        return githubApiService.getUsersRepositories(user.login)
                .map(repositoryResponses -> {
                        final ImmutableList.Builder<Repository> listBuilder = ImmutableList.builder();
                        for (RepositoryResponse repositoryResponse : repositoryResponses) {
                            Repository repository = new Repository();
                            repository.id = repositoryResponse.id;
                            repository.name = repositoryResponse.name;
                            repository.url = repositoryResponse.url;
                            listBuilder.add(repository);
                        }
                        return listBuilder.build();
                })
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread());
    }

但我不知道如何转换这种代码的和平：

obs.subscribe(new Observer<List<Integer>>() {
        public void onCompleted() {
            System.out.println("completed");
        }

        public void onError(Throwable e) {
            System.out.println("failure");
        }

        public void onNext(List<Integer> value) {
            System.out.println("onnext=" + value);
        }
    });

我需要像这样裁剪图像

我需要从中心画出局部图像

我知道批量的draw()方法有很多参数,但没有关于所有这些参数的好文档,所以我无法弄清楚如何使用它.

这是我实施的:

public class TexturePart {

    Texture tex;
    Vector2 position;

// Target Dimension of image

    int targetWidth;
    int targetHeight;

// Src Dimensions of Image

    int srcWidth;
    int srcHeight;
    int srcX;
    int srcY;

// Ratio of dimension of target and source

    float srcTargetRatioX;
    float srcTargetRatioY;

// ImagePart variables with values between 0-100 to draw part of image

    int startPercentX;
    int endPercentX;
    int startPercentY;
    int endPercentY;

    int clipWidth;
    int clipHeight;

    int clipSrcWidth;
    int clipSrcHeight;

    public TexturePart(TextureRegion reg, float x, float …

无法在libgdx android上播放声音.

Sound sound = Gdx.audio.newSound(Gdx.files.internal("sound.wav"));
sound.play();

我把"sound.wav"放到了资源文件夹中.

我正在播放在线流媒体播放的媒体播放器:

mMediaPlayer = new MediaPlayer();
try {
    mMediaPlayer.setDataSource("http://online-radioroks.tavrmedia.ua/RadioROKS");
    mMediaPlayer.prepareAsync();

    mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

        public void onPrepared(MediaPlayer mp) {
            start();
        }
    });

    notifyCallbackListeners(PlayerCallbackEvent.PLAYER_SONG_CHANGE);
}
catch (IllegalArgumentException e) {
    e.printStackTrace();
}
catch (IOException e) {
    e.printStackTrace();
} catch (IllegalStateException ex){
    ex.printStackTrace();
}

它运行正常,但是我可以从流中获取数据,就像现在播放的歌曲和收音机的名称一样吗？
