Android实现朋友圈有图片和视频
2016-12-08 10:57

最近开发比较烦，这个作为我第一篇博客吧。
效果就是图上的样子。
首先是布局文件，没什么就是一个RecycleView
然后是item的布局文件，item布局文件是一个cardview。我这个比较乱，因为有圆角图片作为头像，有标题，有内容，然后是一个自定义九宫格的控件，下面是个ImageView作为视频的封面，开始都让他们隐藏，在适配器里判断，让对应的显示出来。
下面我们来看适配器 我适配器更乱 。我先把整体代码贴出来.
其余的也没什么好说的 我主要说说设置封面经历，我要获取网络视频的第一帧作为相册封面，开始写完特别卡，因为每次都要请求，我就想我建一个bitmap的集合把图片存里，然后用position作为key每次我都去我的集合里找一遍，有就从集合取，没有就请求，然后发现还是卡，后来我想那干脆开个线程让她加载，然后发现，加载完以后， 我在切换别的fragment都是空白的 ，后来发现我没写handler通知更新UI。
首先 后台返回的数据有两个集合一个是图片集合一个是视频集合，但视频只有一个所以我判断了视频集合不等于0的时候显示ImageView。
然后点击视频要能播放 所以我把点击事件写在了这里：
然后下面是这设置图片的九宫格控件
NineGridLayout的代码
NineGridTestLayout的代码
然后就是fragment了 这里也没什么好说的。我用了SwipyRefreshLayout作为下拉刷新和上拉加载，我这里面有两个popupwindow 一个是这个fragment的Activity传的拍摄button，一个是item的删除button。
我是Android小渣渣，代码写的一团乱麻。demo是没有的因为项目比较大，没有单独奥，不过哪里缺什么文件，都可以找我。
compile ‘com.android.support:cardview-v7:23.2.0’
compile files(‘libs/universal-image-loader-1.9.5.jar’)图片加载的imageloader
compile ‘com.github.orangegangsters:swipy:1.2.2@aar’
(^__^) 嘻嘻……
效果就是图上的样子。
首先是布局文件，没什么就是一个RecycleView
<android.support.v7.widget.RecyclerView android:id="@+id/dis_rv" android:layout_width="match_parent" android:layout_height="wrap_content"> </android.support.v7.widget.RecyclerView>
然后是item的布局文件，item布局文件是一个cardview。我这个比较乱，因为有圆角图片作为头像，有标题，有内容，然后是一个自定义九宫格的控件，下面是个ImageView作为视频的封面，开始都让他们隐藏，在适配器里判断，让对应的显示出来。

}我是Android小渣渣，代码写的一团乱麻。demo是没有的因为项目比较大，没有单独奥，不过哪里缺什么文件，都可以找我。
compile ‘com.android.support:cardview-v7:23.2.0’
compile files(‘libs/universal-image-loader-1.9.5.jar’)图片加载的imageloader
compile ‘com.github.orangegangsters:swipy:1.2.2@aar’
(^__^) 嘻嘻……
