我如何將 kotlin 代碼轉換為 java [Android]

Question

這是我試圖轉換成 java 但我不明白的代碼，實際上我得到這個代碼作為答案，但他/她在 kotlin 中給了我

Glide.with(context)
            .load(url)
            .listener(object : RequestListener<Drawable> {
                override fun onLoadFailed(e: GlideException?, model: Any?, target: Target<Drawable>?, isFirstResource: Boolean): Boolean {
                    //TODO: something on exception
                }
                override fun onResourceReady(resource: Drawable?, model: Any?, target: Target<Drawable>?, dataSource: DataSource?, isFirstResource: Boolean): Boolean {
                    Log.d(TAG, "OnResourceReady")
                    dummyShimmerView.visibility = View.GONE
                    postImageView.visibility = View.VISIBLE
                    return false
                }
            })
            .into(imgView)

Answer 1

您可以使用：

     Glide
        .with(context)
        .load("url")
        .listener(new RequestListener<Drawable>() {
            @Override
            public boolean onLoadFailed(@Nullable @org.jetbrains.annotations.Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
                return false;
            }

            @Override
            public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
                dummyShimmerView.setVisibility(View.GONE);
                postImageView.setVisibility(View.VISIBLE);
                return false;
            }
        })
        .into(imageView);

我認為您感到困惑的是RequestListener部分。 Kotlin 使用object表示法來實現接口。 所以你的代碼將大致翻譯成這個

 Glide.with(context).load(...)
                .listener(new RequestListener<Drawable>() {
        @Override
        public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
          //TODO
          return false;
        }
        @Override
        public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
          // Todo
          return false;
        }
      })

                }).into(imgView);
