很常见的一种成果，点击评论弹出输入框，点空白区域或点“发送”后输入框隐没并收起键盘，通常会遇到键盘遮挡输入框问题，应用Dialog的形式解决这个问题绝对简略点，更重要是能代码模块化减少复用性。
dialog_family_dynamic_comment.xml 评论布局文件

R.style.DialogFullScreen 让Dialog全屏。
<style name="DialogFullScreen"> <item name="android:windowFullscreen">true</item> <item name="android:windowNoTitle">true</item></style>应用
FamilyDynamicCommentDialog familyDynamicCommentPopup = new FamilyDynamicCommentDialog(this,this);familyDynamicCommentPopup.show();
