摘要: 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));
