滑行不起作用？這是錯誤：

Question

我正在開發一個應用程序，顯示歌曲的所有專輯封面圖片。 所以我使用glide來加載和緩存圖像，並避免OutofMemoryError。

這是AlbumAdapter我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; 
} 

這是錯誤我得到：

Error:(77, 18) error: no suitable method found for with(AlbumAdapter)

(actual argument AlbumAdapter cannot be converted to android.support.v4.app.Fragment by method invocation conversion)

Answer 1

你需要通過上下文與Glide

Glide.with(this) // will not work 

通行證上下文從您的Activity/Fragment到AlbumAdapter

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

，並且使用帶有Glide

Glide.with(mContext) 

這種情況下，如果你有Activity，那麼你需要使用new AlbumAdapter(ActivityName.this)和Fragment你需要使用new AlbumAdapter(getActivity())
