JCVideoPlayerStandard是一个使用很简单的视频开源库，而且功能很强大,3行代码实现简单的视频播放
特征：
- 视频全屏和浮动小窗口
- 完全定制ui
- 在
ListView，ViewPager和ListView，ViewPager和Fragment其他嵌套片段和视图的情况下，它工作得很好 - Gestrues修改进度和音量
- 适应屏幕尺寸，其中至少视频的宽度或长度是自适应的，而另一个在屏幕上居中
- 进入或退出全屏时不会打扰或改变播放状态
- 重力传感器全自动全屏
- 具有本地视频控制的WebView
- 支持https和rtsp
- 小于100kb

效果图（在Listview显示每个视频）： 结构图：
还是相同的套路，先使用okhttp获取到json数据，然后解析json数据显示到listview上，这里会使用到okhttp（网络请求库）、Picasso（图片缓存库）和jiecaovideoplayer（视频播放库）
1、导入相应的库
okhttp
Picasso
jiecaovideoplayer
2、activity_main布局添加listview
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.wdl.video_demo.MainActivity">
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/lv" />
</LinearLayout>
3、创建listview的item布局lv_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard
android:layout_marginTop="5dp"
android:id="@+id/videoplayer"
android:layout_width="match_parent"
android:layout_height="200dp"/>
</LinearLayout>4、MainActivity.java
public class MainActivity extends AppCompatActivity {
public ListView lv;
String date;
public video_item video;
public ArrayList<Map<String, Object>> list = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//listview控件
lv = (ListView) findViewById(R.id.lv);
//获取到json数据
initdate();
}
private void initdate() {
list.clear();
//线程
new Thread(new Runnable() {
@Override
public void run() {
OkHttpClient okHttpClient=new OkHttpClient();
//服务器返回的地址
Request request=new Request.Builder()
.url("http://192.168.1.6:8080/date.json").build();
try {
Response response=okHttpClient.newCall(request).execute();
//得到数据
date=response.body().string();
//打印出是否得到数据，因为线程中无法执行主线程操作所以我们使用handler
Message mes=new Message();
mes.what=2;
handler.sendMessage(mes);
//解析json数据
JsonJX(date);
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();
}
public void JsonJX(String date) {
//数据是否为空
if (date != null) {
try {
//数据的解析
JSONObject video_object = new JSONObject(date);
String flag = video_object.getString("flag");
if (flag.equals("success")) {
JSONArray array = video_object.getJSONArray("activity");
for (int i = 0; i < array.length(); i++) {
JSONObject object = array.getJSONObject(i);
String video_titie=object.getString("video_title");
String video_url=object.getString("video_url");
String video_pic=object.getString("video_pic");
//存入Map
Map<String,Object> map=new HashMap<>();
map.put("title",video_titie);
map.put("url",video_url);
map.put("pic",video_pic);
list.add(map);
}
}
//调用适配器
Message mes=new Message();
mes.what=1;
handler.sendMessage(mes);
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Message mes=new Message();
mes.what=3;
handler.sendMessage(mes);
}
}
public Handler handler=new Handler(){
@Override
public void handleMessage(Message msg) {
switch (msg.what){
case 1:
video=new video_item(MainActivity.this,list);
lv.setAdapter(video);
break;
case 2:
Log.i("TAG","-------------"+date);
break;
case 3:
Toast.makeText(MainActivity.this,"数据是空的！",Toast.LENGTH_LONG).show();
break;
}
}
};
//监听返回键如果不写视频播放在全屏时点击返回则直接退出.
@Override
public void onBackPressed() {
if (JCVideoPlayer.backPress()) {
return;
}
super.onBackPressed();
}
@Override
protected void onPause() {
super.onPause();
JCVideoPlayer.releaseAllVideos();
}
}5、创建适配器video_item
public class video_item extends BaseAdapter {
public Context con;
public ArrayList<Map<String,Object>> list;
public LayoutInflater inflater;
public video_item(Context context, ArrayList<Map<String,Object>> list){
this.con=context;
this.list=list;
this.inflater=LayoutInflater.from(con);
}
@Override
public int getCount() {
return list.size();
}
@Override
public Object getItem(int position) {
return list.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView==null){
holder=new ViewHolder();
convertView=inflater.inflate(R.layout.lv_item,null);
holder.jcVideoPlayerStandard= (JCVideoPlayerStandard) convertView.findViewById(R.id.videoplayer);
convertView.setTag(holder);
}else{
holder= (ViewHolder) convertView.getTag();
}
//加载视频
holder.jcVideoPlayerStandard.setUp(list.get(position).get("url").toString(),
JCVideoPlayerStandard.SCREEN_LAYOUT_NORMAL,
list.get(position).get("title").toString());
//判断获取的图片是否为空
if (TextUtils.isEmpty(list.get(position).get("pic").toString())){
//空时
Picasso
.with(con)
.cancelRequest(holder.jcVideoPlayerStandard.thumbImageView);
holder.jcVideoPlayerStandard.thumbImageView.
setImageDrawable(con.getResources().
getDrawable(R.mipmap.f));//当图片为空时显示的图片
}else {
//这需要的图片是显示在视频没播放的情况下显示的图片
Picasso
.with(con)
.load(list.get(position).get("pic").toString())
.placeholder(con.getResources().getDrawable(R.mipmap.timg))//图片加载中显示
.into(holder.jcVideoPlayerStandard.thumbImageView);
}
return convertView;
}
class ViewHolder{
JCVideoPlayerStandard jcVideoPlayerStandard;
}
}
最后一步网络权限添加：
<uses-permission android:name="android.permission.INTERNET" />
