Android怎么实现网易新闻的图文混排？

刚开始以为是WebView，后来发现被坑了。不断在https://impress.pw寻找，找到http://stackoverflow.com/questions/25194549/using-picasso-with-image-getter

问题解决，贴一下源码：

public class PicassoImageGetter implements Html.ImageGetter {    private TextView textView = null;    public PicassoImageGetter(TextView target) {        textView = target;    }    @Override    public Drawable getDrawable(final String source) {        BitmapDrawablePlaceHolder drawable = new BitmapDrawablePlaceHolder();        Picasso.with(ShopApp.GLOBAL_CONTEXT)                .load(source)                .placeholder(R.drawable.item_defaut_img)//                .error(R.drawable.)                .into(drawable);        return drawable;    }    class BitmapDrawablePlaceHolder extends BitmapDrawable implements Target {        protected Drawable drawable;        @Override        public void draw(final Canvas canvas) {            if (drawable != null) {                drawable.draw(canvas);            }        }        public void setDrawable(Drawable drawable) {            this.drawable = drawable;            drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());            setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());            if (textView != null) {                textView.setText(textView.getText());            }        }        @Override        public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {            setDrawable(new BitmapDrawable(ShopApp.GLOBAL_CONTEXT.getResources(), bitmap));        }        @Override        public void onBitmapFailed(Drawable errorDrawable) {            setDrawable(errorDrawable);        }        @Override        public void onPrepareLoad(Drawable placeHolderDrawable) {        }    }}

调用非常简单：

 contentView.setText(Html.fromHtml(dto.content, new PicassoImageGetter(contentView), null));
