Android：通过滑动下载drawable

Question

我正在尝试更改我的适配器内的radiobutton.buttonDrawable。从我的可绘制文件夹中选择静态可绘制对象有效。我现在想要的是从我的 cloud-firestore-storage 下载可绘制对象（.svg 文件），将它们转换为可绘制对象并将它们设置为单选按钮。

我当前的实现不起作用，因为它什么都不做（不会改变任何东西）。我已经检查了网址 (getItem(position).icon)，它们看起来是正确的。

目前的做法

class ShopFilterItemAdapter @Inject constructor(
    // @ApplicationContext private val context: Context
) : ListAdapter<ShopFilterCategory, ShopFilterItemAdapter.ShopFilterViewHolder>(Companion) {
    private var checkedRadioButton: CompoundButton? = null
    var defaultCheckedId: Int = 0
    private lateinit var listener: OnItemSelectedListener

    companion object: DiffUtil.ItemCallback<ShopFilterCategory>() {
        override fun areItemsTheSame(oldItem: ShopFilterCategory, newItem: ShopFilterCategory): Boolean = oldItem === newItem
        override fun areContentsTheSame(oldItem: ShopFilterCategory, newItem: ShopFilterCategory): Boolean = oldItem == newItem
    }

    inner class ShopFilterViewHolder(val binding: ShopFilterListItemBinding) : RecyclerView.ViewHolder(binding.root)

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ShopFilterViewHolder {
        val layoutInflater = LayoutInflater.from(parent.context)
        val binding = ShopFilterListItemBinding.inflate(layoutInflater, parent, false)
        return ShopFilterViewHolder(binding)
    }

    override fun onBindViewHolder(holder: ShopFilterViewHolder, position: Int) {
        holder.binding.filterItem = getItem(position)

        if (checkedRadioButton == null && defaultCheckedId == position) holder.binding.rbItem.isChecked = true
        
        if (holder.binding.rbItem.isChecked) checkedRadioButton = holder.binding.rbItem

        // Trying to load the images here
        Glide.with(holder.binding.root)
            .asDrawable()
            .load(getItem(position).icon)
            .into(object : CustomTarget<Drawable>() {
                override fun onResourceReady(resource: Drawable, transition: Transition<in Drawable>?) {
                    holder.binding.rbItem.buttonDrawable = resource
                }

                override fun onLoadCleared(placeholder: Drawable?) {
                    TODO("Not yet implemented")
                }

            })

        holder.binding.executePendingBindings()
    }

编辑

我错了，它抛出了一个错误：

Answer 1

我已经设法解决了这个问题，不幸的是，滑翔不可能，而是线圈。

1。添加必要的依赖项

implementation "io.coil-kt:coil-base:1.1.0" // or "io.coil-kt:coil-1.1.0" if you don't want to use dependency Injection
implementation "io.coil-kt:coil-svg:1.1.0"

2。构造 ImageLoader Singleton 并添加 SVGEndoder

@Provides
@Singleton
fun provideImageLoader(@ApplicationContext context: Context) = ImageLoader.Builder(context)
    .componentRegistry { add(SvgDecoder(context)) }
    .build()

3.构建请求

fun buildRequest(context: Context, data: Any, target: RadioButton) = ImageRequest.Builder(context)
    .data(data)
    .target { drawable -> target.buttonDrawable = drawable }
    .size(64, 60) // unfortunately I was not able to get the default radiobutton.drawable size here
    .build()

4。适配器内部

override fun onBindViewHolder(holder: YourHolder, position: Int) {

   val newRequest = shopFilterValidator.buildRequest(
       context = holder.binding.rbItem.context,
       data = getItem(position).icon, // here a url from firebase
       target = holder.binding.rbItem
   )

   imageLoader.enqueue(newRequest)
}

这会将svg图像加载为drawables并将它们作为radiobutton.drawable
