用于视频播放的第三方插件，效果如图：

2.application

/**
 * @author : wangtt
 * @time : 16/9/5
 */
public class VPApplication extends Application {
    public static VPApplication instance;
    public JCVideoPlayerStandard VideoPlaying;

    @Override
    public void onCreate() {
        super.onCreate();
        instance = this;
    }
}

3.在MainActivity里，如果项目没有actionbar和toolbar的话要设置：

 JCVideoPlayer.ACTION_BAR_EXIST = false;
 JCVideoPlayer.TOOL_BAR_EXIST = false;

否则会出异常。

@Override
    protected void onPause() {
        super.onPause();
        if(VPApplication.instance.VideoPlaying!=null)
        {
            if(VPApplication.instance.VideoPlaying.currentState== JCVideoPlayer.CURRENT_STATE_PLAYING)
            {
                VPApplication.instance.VideoPlaying.startButton.performClick();
            }else if (VPApplication.instance.VideoPlaying.currentState== JCVideoPlayer.CURRENT_STATE_PREPAREING)
            {
                JCVideoPlayer.releaseAllVideos();
            }
        }
    }

4.适配器item

  <fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard
        android:id="@+id/videoplayer"
        android:layout_width="match_parent"
        android:layout_height="260dp"/>

5.视频列表，如果有可见时播放视频的需求，实现方式如下：

 videoList.setOnScrollListener(new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) {
                switch (scrollState) {
                    case AbsListView.OnScrollListener.SCROLL_STATE_FLING:
                        Log.e("videoTest", "SCROLL_STATE_FLING");
                        break;
                    case AbsListView.OnScrollListener.SCROLL_STATE_IDLE:
                        Log.e("videoTest", "SCROLL_STATE_IDLE");
                        autoPlayVideo(view);//可见时播放视频
                        break;
                    case AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL:
                        Log.e("videoTest", "SCROLL_STATE_TOUCH_SCROLL");
                        break;
                    default:
                        break;
                }
            }

            @Override
            public void onScroll(AbsListView view, int firstVisibleItem,
                                 int visibleItemCount, int totalItemCount) {
                // firstVisibleItem   当前第一个可见的item
                // visibleItemCount   当前可见的item个数
                if (firstVisible == firstVisibleItem) {
                    return;
                }
                firstVisible = firstVisibleItem;
                visibleCount = visibleItemCount;
                totalCount = totalItemCount;
            }
        });
    }

    void autoPlayVideo(AbsListView view) {
        for (int i = 0; i < visibleCount; i++) {
            if (view != null && view.getChildAt(i) != null && view.getChildAt(i).findViewById(R.id.videoplayer) != null) {
                JCVideoPlayerStandard videoPlayerStandard1 = (JCVideoPlayerStandard) view.getChildAt(i).findViewById(R.id.videoplayer);
                Rect rect = new Rect();
                videoPlayerStandard1.getLocalVisibleRect(rect);
                int videoheight3 = videoPlayerStandard1.getHeight();
                if (rect.top == 0 && rect.bottom == videoheight3) {
                    if (videoPlayerStandard1.currentState == JCVideoPlayer.CURRENT_STATE_NORMAL || videoPlayerStandard1.currentState == JCVideoPlayer.CURRENT_STATE_ERROR) {
                        videoPlayerStandard1.startButton.performClick();
                        VPApplication.instance.VideoPlaying = videoPlayerStandard1;
                    }
                    return;
                }

            }
        }
        JCVideoPlayer.releaseAllVideos();
        VPApplication.instance.VideoPlaying = null;
    }

6.适配器getView方法中

//列表滑动时，及时释放资源
 if (convertView != null && convertView.getTag() != null && convertView.getTag() instanceof VideoHolder) {
                ((VideoHolder) convertView.getTag()).jcVideoPlayer.release();
  }


  boolean setUp = viewHolder.jcVideoPlayer.setUp(
                        "http://gslb.miaopai.com/stream/ed5HCfnhovu3tyIQAiv60Q__.mp4", JCVideoPlayer.SCREEN_LAYOUT_LIST,
                        "");
 if (setUp) {     
   //设置视频缩略图
       Glide.with(getActivity()).load("http://a4.att.hudong.com/05/71/01300000057455120185716259013.jpg").into(viewHolder.jcVideoPlayer.thumbImageView);
      }

7.播放视频
videoPlayer.startPlayLocic();
8.退出Activity时，要销毁player，否则会出现退出了还继续播放的情况

  @Override
    public void onDestroy() {
        super.onDestroy();
        try {
            JCVideoPlayer.releaseAllVideos();
        } catch (Exception e) {
        }
    }
        

8.遇到的问题
播放视频时，出现seekbar的thumb圆点被覆盖情况或者使用其他地方使用seekbar时thumb圆点被覆盖情况，如图：

这个问题出现的原因是因为manifest.xml里application节点使用了自定义的theme。
解决办法：在使用了的seekbar的类节点里，加上theme如下：
AndroidManifest.xml

 <activity
            android:name="com.nongji.ah.activity.VideoPlayAct"
            android:screenOrientation="portrait"
            android:theme="@style/AppTheme"></activity>

styles.xml

  <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
