在Android開(kāi)發(fā)過(guò)程中，網(wǎng)頁(yè)代碼的實(shí)現(xiàn)方法是多種多樣的，而當(dāng)普通代碼不能滿足我們的要求時(shí)，通常需要定制另外一個(gè)代碼來(lái)實(shí)現(xiàn)，下面是武林技術(shù)頻道小編為大家介紹的為你展示微博content的封裝和實(shí)現(xiàn)方法的代碼展示，一起進(jìn)入下文了解一下吧！

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：

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

具體的封裝如下：
