Android 模仿發說說

本片博客的事例是根據我自己項目中的部分需求來的，所以有些和這個不相關的內容和源碼，大家可以忽略不計。這種發說說的功能，我也是折騰了很久，今日才得知道，大神請不要見笑，,l裡面的圖片自己找好了，好了，先看效果：

 

property_repair,xml

 

griditem_addpic.xml

 

 

editview_shape.xml //這個是設置圓角的，因為我有這個需求，大家不要可以選擇略過

 

 

tijiao_pingjia.xml 這個是彈窗的布局，也和上面一樣 是我的需求 大家可以不要

 

 

 

下面是程序 我因為項目需求，所有我的不是MainActivity,而是我需求的一個類，大家根據情況自己定義

Property_repair.java
