可以不用經(jīng)過(guò) Html.fromHtml 因?yàn)槲业臄?shù)據(jù)里面含有一點(diǎn) html的標(biāo)簽。所以經(jīng)過(guò)html轉(zhuǎn)換了。
實(shí)現(xiàn)方法：

復(fù)制代碼代碼如下:

 
TextView content = (TextView) convertView.findViewById(R.id.content); 
content.setText(Html.fromHtml("<html><head>"+temp.get(position).getContent()+"</html></head>")); 
CharSequence str = content.getText(); 
SpannableString spann = WeiboUtils.formatContentNoClick(str); 
content.setText(spann); 

具體的封裝如下：

復(fù)制代碼代碼如下:
