android - 从资源中设置壁纸

Question

当我尝试从资源中设置壁纸时，完成工作需要时间，所以也许有更简单的方法而不是我的硬编码

public void Setwallpaper(int position , Context context) throws IOException{    
    AssetManager am = mContext.getAssets();
    nlist = am.list("Gallary");
     BufferedInputStream buf = new BufferedInputStream(am.open(nlist[position]));
     bitmap = BitmapFactory.decodeStream(buf);

     buf.close();
    WallpaperManager myWallpaperManager = WallpaperManager
            .getInstance(context);
    try {
        myWallpaperManager.setBitmap(bitmap);
        Toast.makeText(context, "Wallpaper set",
                0).show();
    } catch (IOException e) {
        Toast.makeText(context,
                "Error setting wallpaper", Toast.LENGTH_SHORT)
                .show();
    }
}

大约需要 3 秒才能完成此操作，而我看到其他应用程序能够在不到一秒的时间内完成此操作，如有任何建议，我将不胜感激，谢谢

试试这个

   WallpaperManager myWallpaperManager =WallpaperManager.getInstance(getApplicationContext());
    InputStream ims = getAssets().open("yourimage.jpg");
    myWallpapaerManager.setStream(ims)
