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：
这里写图片描述
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

compile 'fm.jiecao:jiecaovideoplayer:4.8.3'compile 'com.github.bumptech.glide:glide:3.7.0'

2、添加布局

 <fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard        android:id="@+id/player_list_video"        android:layout_width="match_parent"        android:layout_height="220dp" />

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("http://gslb.miaopai.com/stream/ed5HCfnhovu3tyIQAiv60Q__.mp4", JCVideoPlayer.SCREEN_LAYOUT_LIST, "");        if (setUp) {            Glide.with(MainActivity.this).load("http://a4.att.hudong.com/05/71/01300000057455120185716259013.jpg").into(player.thumbImageView);        }

4、在Activity中

@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：

<!--联网权限-->    <uses-permission android:name="android.permission.INTERNET" />

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

 //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：

package la.trytry.jiecaovideoplayer;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import com.bumptech.glide.Glide;import fm.jiecao.jcvideoplayer_lib.JCVideoPlayer;import fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard;public class MainActivity extends AppCompatActivity {    private String videoUrl = "http://gslb.miaopai.com/stream/ed5HCfnhovu3tyIQAiv60Q__.mp4";    private JCVideoPlayerStandard player;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        player = (JCVideoPlayerStandard) findViewById(R.id.player_list_video);        boolean setUp = player.setUp(videoUrl, JCVideoPlayer.SCREEN_LAYOUT_LIST, "");        if (setUp) {            Glide.with(MainActivity.this).load("http://a4.att.hudong.com/05/71/01300000057455120185716259013.jpg").into(player.thumbImageView);        }        //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();    }    @Override    public void onBackPressed() {        if (JCVideoPlayer.backPress()) {            return;        }        super.onBackPressed();    }    @Override    protected void onPause() {        super.onPause();        JCVideoPlayer.releaseAllVideos();    }}

四、下面回到我们的主题上，实现仿今日头条的视频播放
1、VideoActivity.Java

package la.trytry.jiecaovideoplayer;import android.graphics.Rect;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.widget.AbsListView;import android.widget.ListView;import java.util.ArrayList;import fm.jiecao.jcvideoplayer_lib.JCVideoPlayer;import fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard;public class VideoActivity extends AppCompatActivity {    private String videoUrl = "http://gslb.miaopai.com/stream/ed5HCfnhovu3tyIQAiv60Q__.mp4";    private ListView listView;    private ArrayList<String> datas;    private JCVideoPlayerStandard currPlayer;    private VideoAdapter adapter;    private AbsListView.OnScrollListener onScrollListener;    private int firstVisible;//当前第一个可见的item    private int visibleCount;//当前可见的item个数    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_video);        listView = (ListView) findViewById(R.id.listview);        initDatas();        initListener();    }    private void initDatas() {        datas = new ArrayList<String>();        for (int i = 0; i < 20; i++) {            datas.add(videoUrl);        }        adapter = new VideoAdapter(VideoActivity.this, datas, R.layout.item_video);        listView.setAdapter(adapter);    }    /**     * 滑动监听     */    private void initListener() {        onScrollListener = new AbsListView.OnScrollListener() {            @Override            public void onScrollStateChanged(AbsListView view, int scrollState) {                switch (scrollState) {                    case AbsListView.OnScrollListener.SCROLL_STATE_FLING:                        break;                    case AbsListView.OnScrollListener.SCROLL_STATE_IDLE:                        //滑动停止自动播放视频                        autoPlayVideo(view);                        break;                    case AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL:                        break;                }            }            @Override            public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {                if (firstVisible == firstVisibleItem) {                    return;                }                firstVisible = firstVisibleItem;                visibleCount = visibleItemCount;            }        };        listView.setOnScrollListener(onScrollListener);    }    /**     * 滑动停止自动播放视频     */    private void autoPlayVideo(AbsListView view) {        for (int i = 0; i < visibleCount; i++) {            if (view != null && view.getChildAt(i) != null && view.getChildAt(i).findViewById(R.id.player_list_video) != null) {                currPlayer = (JCVideoPlayerStandard) view.getChildAt(i).findViewById(R.id.player_list_video);                Rect rect = new Rect();                //获取当前view 的 位置                currPlayer.getLocalVisibleRect(rect);                int videoheight = currPlayer.getHeight();                if (rect.top == 0 && rect.bottom == videoheight) {                    if (currPlayer.currentState == JCVideoPlayer.CURRENT_STATE_NORMAL                            || currPlayer.currentState == JCVideoPlayer.CURRENT_STATE_ERROR) {                        currPlayer.startButton.performClick();                    }                    return;                }            }        }        //释放其他视频资源        JCVideoPlayer.releaseAllVideos();    }    @Override    public void onBackPressed() {        if (JCVideoPlayer.backPress()) {            return;        }        super.onBackPressed();    }    @Override    protected void onPause() {        super.onPause();        JCVideoPlayer.releaseAllVideos();    }}

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
2、VideoAdapter.java

package la.trytry.jiecaovideoplayer;import android.content.Context;import com.bumptech.glide.Glide;import com.zhy.adapter.abslistview.CommonAdapter;import com.zhy.adapter.abslistview.ViewHolder;import java.util.List;import fm.jiecao.jcvideoplayer_lib.JCVideoPlayer;import fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard;/** * @author: lijuan * @description: 适配器 * @date: 2016-12-04 * @time: 17:04 */public class VideoAdapter extends CommonAdapter<String> {    private Context mContext;    public VideoAdapter(Context context, List<String> datas, int layoutId) {        super(context, layoutId, datas);        this.mContext = context;    }    @Override    protected void convert(ViewHolder viewHolder, String url, int position) {        JCVideoPlayerStandard player = viewHolder.getView(R.id.player_list_video);        if (player != null) {            player.release();        }        boolean setUp = player.setUp(url, JCVideoPlayer.SCREEN_LAYOUT_LIST, "");        if (setUp) {            Glide.with(mContext).load("http://a4.att.hudong.com/05/71/01300000057455120185716259013.jpg").into(player.thumbImageView);        }    }}

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

compile 'com.zhy:base-adapter:3.0.3'1

3、item_video.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:orientation="vertical">    <fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard        android:id="@+id/player_list_video"        android:layout_width="match_parent"        android:layout_height="190dp" />    <RelativeLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:paddingBottom="8dp"        android:paddingTop="8dp">        <ImageView            android:id="@+id/img_video_icon"            android:layout_width="30dp"            android:layout_height="30dp"            android:layout_marginLeft="12dp"            android:src="@mipmap/icon_default_head" />        <TextView            android:id="@+id/tv_video_userName"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_centerVertical="true"            android:layout_marginLeft="12dp"            android:layout_toRightOf="@id/img_video_icon"            android:text="空城旧梦" />        <TextView            android:id="@+id/tv_video_comment"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_alignParentRight="true"            android:layout_centerVertical="true"            android:layout_marginRight="12dp"            android:drawablePadding="4dp"            android:drawableLeft="@mipmap/icon_comment"            android:text="21"            android:textSize="12sp" />        <TextView            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_centerVertical="true"            android:layout_marginRight="12dp"            android:layout_toLeftOf="@id/tv_video_comment"            android:text="3万次播放" />    </RelativeLayout></LinearLayout>

4、activity_video.xml

<?xml version="1.0" encoding="utf-8"?><ListView xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/listview"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" />1
