Android 实现朋友圈有图片和视频

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 
<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。

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。

if (datas.get(position).getSpList().size() != ) {
            holder.frameLayout.setVisibility(View.VISIBLE);
            final String file = "http://124.193.178.222:1888/JwsdApp/" + datas.get(position).getSpList().get().getSpURL();
            Map<Integer, Bitmap> bitmapMap = new HashMap<>();//bitmap的集合
            if (bitmapMap.containsKey(position)) {
                 bitmap = bitmapMap.get(position);
                holder.pic_iv.setImageBitmap(bitmap);//集合要是存在就设置上
            } else {
                Thread t = new Thread(new Runnable(){
                    public void run(){//开启线程获取视频第一帧
                        MediaMetadataRetriever retriever = new MediaMetadataRetriever(); //获取网络视频
                        try {
                            retriever.setDataSource(file, new HashMap<String, String>());
                            bitmap = retriever.getFrameAtTime();
                            if (bitmap!=null){
                                Message message = handler.obtainMessage();//用handler发送通知
                                message.what = ;
                                message.obj = bitmap;
                                handler.sendMessage(message);

                            }

                        } catch (IllegalArgumentException e) {
                            e.printStackTrace();
                        } catch (RuntimeException e) {
                            e.printStackTrace();
                        } finally {
                            try {
                                retriever.release();
                            } catch (RuntimeException e) {
                                e.printStackTrace();
                            }
                        }
                    }});
                t.start();

            }

然后点击视频要能播放 所以我把点击事件写在了这里：

 holder.start_iv.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent intent = new Intent(fm.getActivity(), PlayMovieActivity.class);
                    Bundle bundle = new Bundle();
                    bundle.putString("text", file);
                    intent.putExtras(bundle);
                    fm.getActivity().startActivity(intent);
                }
            });

然后下面是这设置图片的九宫格控件

            imageList.clear();
            for (int i = ; i < datas.get(position).getTpList().size(); i++) {
                imageList.add("http://124.193.178.222:1888/JwsdApp/" + datas.get(position).getTpList().get(i).getTpURL());
            }
            holder.layout.setUrlList(imageList);

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。
