TextView 支持 html 图片显示

引用:http://woshao.com/article/697693b8b65e11e0a18f000c29fa3b3a/

在TextView中显示HTML内容的方法如下所示:

1 TextView description=(TextView)findViewById(R.id.description);

2 description.setText(Html.fromHtml(item.getDescription()));

如果HTML中有图片的话,显示出来的图片会被一个小框取代,那么怎么样才能看到图片呢?查看了一下API,

android.text.Html还还有 另一个方法:

Html.fromHtml(String source,ImageGetter imageGetter,TagHandler tagHandler)


例:

ImageGetter imgGetter = new Html.ImageGetter() {
02         public Drawable getDrawable(String source) {
03             Drawable drawable = null;
04             Log.d("Image Path", source);
05             URL url;
06             try {
07                 url = new URL(source);
08                 drawable = Drawable.createFromStream(url.openStream(),"");
09             catch (Exception e) {
10                 return null;
11             }
12             drawable.setBounds(00, drawable.getIntrinsicWidth(), drawable
13                     .getIntrinsicHeight());
14             return drawable;
15         }
16     };
17 .........
18 TextView description=(TextView)findViewById(R.id.description);
19 description.setText(Html.fromHtml(item.getDescription(),imgGetter,null));
