前段时间由于项目需要用到类似于今日头条的视频播放器，实现在线播放，边缓存边播放，当然也可以播放本地文件，如下图：
这里我推荐大家使用的是jiecaovideoplayer开源库，这个库的播放引擎是ijkplayer，它调用ffmpeg， 原项目GitHub地址：https://github.com/lipangit/JieCaoVideoPlayer
一、项目引入：
1、添加类库
|
1
2
|
compile
'fm.jiecao:jiecaovideoplayer:4.8.3'
compile
'com.github.bumptech.glide:glide:3.7.0'
|
2、添加布局
|
1
|
<fm.jiecao.jcvideoplayer_lib.jcvideoplayerstandard android:id=
"@+id/player_list_video"
android:layout_width=
"match_parent"
android:layout_height=
"220dp"
></fm.jiecao.jcvideoplayer_lib.jcvideoplayerstandard>
|
3、下面就是我所说的通过设置视频地址、缩略图地址、标题等几行代码快速实现视频的播放啦
|

|
JCVideoPlayerStandard player = (JCVideoPlayerStandard) findViewById(R.id.player_list_video);
boolean
setUp = player.setUp(
"https://gslb.miaopai.com/stream/ed5HCfnhovu3tyIQAiv60Q__.mp4"
, JCVideoPlayer.SCREEN_LAYOUT_LIST,
""
);
if
(setUp) {
Glide.with(MainActivity.
this
).load(
"https://a4.att.hudong.com/05/71/01300000057455120185716259013.jpg"
).into(player.thumbImageView);
}
|
4、在Activity中
|
1

5
6

9
10
11
12
13
|
@Override
public
void
onBackPressed() {
if
(JCVideoPlayer.backPress()) {
return
;
}
super
.onBackPressed();
}
@Override
protected
void
onPause() {
super
.onPause();
JCVideoPlayer.releaseAllVideos();
}
|
5、还有一点不要忘记哦，要添加权限滴：
|
1
2
|
<!--联网权限-->
<uses-permission android:name=
"android.permission.INTERNET"
></uses-permission>
|
下面我们来看看我们运行效果：
二、如何使用jiecaovideoplayer播放本地视频
注意：jiecaovideoplayer支持file:///开头的文件播放，但是不支持assets或者raw目录下的视频，assets下的视频要先复制到本地路径才能播放，至于怎么监听播放完全呢，要继承JCvideoPlayerStandard 复写onAutoCOmplete函数
三、模拟用户点击开始按钮，直接进入全屏
|
1
2
3
4
|
//直接进入全屏
player.startFullscreen(
this
, JCVideoPlayerStandard.
class
, videoUrl,
""
);
//模拟用户点击开始按钮，NORMAL状态下点击开始播放视频，播放中点击暂停视频
player.startButton.performClick();
|
我把代码都贴出来吧：

在我们滑动的时候，jiecaovideoplayer会自动停止正在播放的视频，这里面我还添加了一个功能，就是监听当滑动停止的时候自动播放下一个视频

这里的适配器，我继承了鸿洋大神写的万能的Adapter，所以我们还需添加这个库的引用

下面我们看看最终的效果
好了，本篇文章已经全部写完但是当在fragment中加载视屏时无法全屏播放，不知道为啥
