如何从滑行中获得可绘制的？ 实际上我想从滑动中返回drawable，加载图像并放入imageview

Question

这是我的代码：

d.setBounds(15, 8, d.getIntrinsicWidth(), d.getIntrinsicHeight());
ImageSpan span = new ImageSpan(d,ImageSpan.ALIGN_BOTTOM) {}

使用最新版本的Glide

implementation 'com.github.bumptech.glide:glide:4.9.0'

科特林：

Glide.with(this)
        .asBitmap()
        .load(imagePath)
        .into(object : CustomTarget<Bitmap>(){
            override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
                imageView.setImageBitmap(resource)
            }
            override fun onLoadCleared(placeholder: Drawable?) {
                // this is called when imageView is cleared on lifecycle call or for
                // some other reason.
                // if you are referencing the bitmap somewhere else too other than this imageView
                // clear it here as you can no longer have the bitmap
            }
        })

位图大小：

如果要使用图像的原始大小，请使用上面的默认构造函数，否则可以传递所需的位图大小

into(object : CustomTarget<Bitmap>(1980, 1080)

Java的：

Glide.with(this)
        .asBitmap()
        .load(path)
        .into(new CustomTarget<Bitmap>() {
            @Override
            public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                imageView.setImageBitmap(resource);
            }

            @Override
            public void onLoadCleared(@Nullable Drawable placeholder) {
            }
        });
