Question

我正在开发一个应用程序，显示歌曲的所有专辑封面图像。所以我使用滑动来加载和缓存图像并避免使用OutofMemoryError。

这是我在AlbumAdapter中的getView方法：

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    RelativeLayout albumsLay = (RelativeLayout)songInf.inflate
            (R.layout.album_layout, parent, false);
    ImageView coverView = (ImageView)albumsLay.findViewById(R.id.song_cover);

    //get song using position
    Song currSong = songs.get(position);

    if (Drawable.createFromPath(currSong.getCover()) != null) {
        Drawable img = Drawable.createFromPath(currSong.getCover());
                    Glide.with(this).load(img).into(coverView);

    }

    albumsLay.setTag(position);
    return albumsLay;
}

这是我得到的错误：

Error:(77, 18) error: no suitable method found for with(AlbumAdapter)
method Glide.with(android.support.v4.app.Fragment) is not applicable

Answer 1

您需要使用Glide

传递上下文

Glide.with(this) // will not work

将上下文从Activity/Fragment传递到AlbumAdapter

Context mContext;
public AlbumAdapter(Context context){
    mContext = context;
}

并将该上下文与Glide

一起使用

Glide.with(mContext)

如果您有Activity，那么您需要使用new AlbumAdapter(ActivityName.this)，而对于Fragment则需要使用new AlbumAdapter(getActivity())

Answer 2

对于glide的更新版本，

RequestManager manager = Glide.with(imageView);

manager.load(imageUrl).into(imageView);

滑翔不起作用？这是错误：
