Android展示Html富文本

1、展示富文本并可展示图片,点击图片可以进行预览。

                        <TextView
                            android:id="@+id/html_tv"
                            android:layout_width="match_parent"
                            android:layout_height="match_parent"
                            android:layout_marginTop="30dp"
                            />  

htmlTv = findViewById(R.id.html_tv);

htmlTv.setMovementMethod(LinkMovementMethod.getInstance());

HtmlText.from(data.remarks).setImageLoader(new HtmlImageLoader() {
                @Override
                public void loadImage(String s, Callback callback) {
                    Glide.with(PreferDetailNewActivity.this)
                            .asBitmap()
                            .load(s)
                            .into(new SimpleTarget<Bitmap>() {
                                @Override
                                public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                                    callback.onLoadComplete(resource);
                                }

                                @Override
                                public void onLoadFailed(@Nullable Drawable errorDrawable) {
                                    super.onLoadFailed(errorDrawable);
                                    callback.onLoadFailed();
                                }
                            });
                }

                @Override
                public Drawable getDefaultDrawable() {
                    return (Drawable) ContextCompat.getDrawable(PreferDetailNewActivity.this, R.drawable.image_placeholder_loading);
                }

                @Override
                public Drawable getErrorDrawable() {
                    return (Drawable) ContextCompat.getDrawable(PreferDetailNewActivity.this, R.drawable.image_placeholder_fail);
                }

                @Override
                public int getMaxWidth() {
                    return htmlTv.getWidth();
                }

                @Override
                public boolean fitWidth() {
                    return false;
                }
            }).setOnTagClickListener(new OnTagClickListener() {
                @Override
                public void onImageClick(Context context, List<String> list, int i) {
                    if (list != null) {
                        jup(i, list);
                    }
                    Log.e("详情图片点击调试", "已点击");
                }

                @Override
                public void onLinkClick(Context context, String s) {

                }
            }).into(htmlTv);

    private void jup(int position, List<String> list) {
        PictureConfig.Builder builder = new PictureConfig.Builder();
        PictureConfig picture = builder.setListData((ArrayList<String>) list)
                .setPosition(position)
                .setDownloadPath("PIC")
                .needDownload(true) //是否支持下载
                .setPlacrHolder(R.drawable.image_placeholder_loading) //占位符
                .build();
        ImagePagerActivity.startActivity(this, picture);
    }

2、可以展示图片，以及大部分的html标签，但是图片不能预览

引入依赖：https://github.com/SufficientlySecure/html-textview

implementation 'org.sufficientlysecure:html-textview:4.0'

    <org.sufficientlysecure.htmltextview.HtmlTextView
        android:id="@+id/tv_rich_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="50dp"
        android:layout_marginRight="20dp"
        android:textColor="#7F7F7F"
        />

htmlTv = findViewById(R.id.tv_rich_text);

htmlTv.setHtml(entity.getTitle(), new HtmlHttpImageGetter(htmlTv));

3、出现富文本无法展示的问题，还可以使用WebView进行显示富文本

webView如果使用xml布局方式实现，会出现高度无法自适应的情况，所有改用代码实现。
参考：https://www.jianshu.com/p/3b892cacd1c5
使用：

wv = WebView(me)
wv.loadDataWithBaseURL(null, data.ruleWords, "text/html", "utf-8", null) //data.ruleWords是你的富文本
sllHtml.addView(wv) //添加到一个LinearLayout布局
