方便使用的评论工具类，而且能监听到小键盘消失事件，能返回小键盘的高度，追踪评论位置。
只是评论功能，木有表情等其他的东东（表情目前都用VP+GV写的，正在尝试使用一个VIew来做分页）
具体文件中有注释，效果看下qq空间的评论就好。
工具使用方式
//第一种姿势@Overridepublic void onItemClick(AdapterView<?> parent, final View view, int posi, long id) {talkPopWindow = new TalkPopWindow(activity, new TalkPopWindow.OnSendMessage() {@Overridepublic void onSendMessage(String msg) {//发送消息哦}@Overridepublic void onRefreshlayout(int variation,int containerHeight) {//在这里获得小键盘活动的高度之后，计算控件需要滑动的距离talkPopWindow.calculateExternalOffset(dongtai_lv,view,variation,0);}}, 1);talkPopWindow.pop();}//第二种姿势View.OnClickListener onClickListener = new View.OnClickListener() {@Overridepublic void onClick(final View v) {// if(talkPopWindow == null){talkPopWindow = new TalkPopWindow(activity, new TalkPopWindow.OnSendMessage() {@Overridepublic void onSendMessage(String msg) {//发送你的消息}@Overridepublic void onRefreshlayout(int variation,int containerHeight) {//在这里获得小键盘活动的高度之后，计算控件需要滑动的距离//因为这里不是在onItemClick中，所以要拿到现在的item布局，需要按照层次获取父布局：我这里是两层//当然你也可以使用别的方法，这里只是需要拿到item来计算高度talkPopWindow.calculateExternalOffset(dongtai_lv,(View)(v.getParent().getParent()),variation,0);}}, 1);talkPopWindow.pop();}
