在之前的项目中用到了视频播放的功能，在网上看了看使用了大家用的比较多的一个开源项目JiaoZiVideo让我迅速的实现了视频播放的相关功能。
JiaoZiVideo的简单使用
代码语言：javascript复制JZVideoPlayerStandard jzVideoPlayerStandard = (JZVideoPlayerStandard) findViewById(R.id.jz_vedio);
//设置播放视频链接和视频标题
jzVideoPlayerStandard.setUp(VEDIO_URL
, JZVideoPlayer.SCREEN_WINDOW_NORMAL, "饺子在哪里");
//为播放视频设置封面图
jzVideoPlayerStandard.thumbImageView.setImageResource(R.mipmap.ic_launcher);Jz播放器的简单使用，只需要在布局文件中引入该文件，然后为其设置待播放视频的链接和播放视频的封面图即可。其它的播放相关的无需我们关心。
代码结构分析
JiaoZiVideo主要特点
- 可以完全自定义UI和任何功能
- 可以完全自定义UI和任何功能
- 一行代码切换播放引擎，支持的视频格式和协议取决于播放引擎，android.media.MediaPlayer ijkplayer
- 完美检测列表滑动
- 可实现全屏播放，小窗播放
- 能在ListView、ViewPager和ListView、ViewPager和Fragment等多重嵌套模式下全屏工作
- 可以在加载、暂停、播放等各种状态中正常进入全屏和退出全屏
- 多种视频适配屏幕的方式，可铺满全屏，可以全屏剪裁
- 重力感应自动进入全屏
- 全屏后手势修改进度和音量
- Home键退出界面暂停播放，返回界面继续播放
JiaoZiVideo的使用指南
1…添加类库
代码语言：javascript复制implementation 'cn.jzvd:jiaozivideoplayer:7.0.3'2.添加布局
代码语言：javascript复制<LinearLayout
android:layout_width="match_parent"
android:layout_height="200dp">
<cn.jzvd.demo.CustomJzvd.MyJzvdStd
android:id="@ id/jz_video"
android:layout_width="match_parent"
android:layout_height="200dp" />
</LinearLayout>3.设置视频地址、缩略图地址、标题
代码语言：javascript复制MyJzvdStd jzvdStd = (MyJzvdStd) findViewById(R.id.jz_video);
jzvdStd.setUp("http://jzvd.nathen.cn/c6e3dc12a1154626b3476d9bf3bd7266/6b56c5f0dc31428083757a45764763b0-5287d2089db37e62345123a1be272f8b.mp4"
, "饺子闭眼睛");
jzvdStd.thumbImageView.setImage("http://p.qpic.cn/videoyun/0/2449_43b6f696980311e59ed467f22794e792_1/640");4.在Activity中
代码语言：javascript复制@Override
public void onBackPressed() {
if (Jzvd.backPress()) {
return;
}
super.onBackPressed();
}
@Override
protected void onPause() {
super.onPause();
Jzvd.releaseAllVideos();
}5.在AndroidManifest.xml中
代码语言：javascript复制<activity
android:name=".MainActivity"
android:configChanges="orientation|screenSize|keyboardHidden"
android:screenOrientation="portrait" /> <!-- or android:screenOrientation="landscape"-->以上只是简单的播放视频功能，但是大家的项目需求里应该不仅仅只是需要播放视频就好了，所以下面写一下还有哪些常规使用方法 加缩略载图
代码语言：javascript复制Glide.with(this).load(Url).into(myJzvdStd.thumbImageView); //推荐使用Glide自动播放
代码语言：javascript复制 自动播放有两种 这里随便选择添加一个，
1. myJzvdStd.startButton.performClick();
2. myJzvdStd.startVideo();跳转制定位置播放
代码语言：javascript复制 //这里只有开始播放时才生效
mJzvdStd.seekToInAdvance = 20000;
//跳转制定位置播放
JZMediaManager.seekTo(30000);
2.播放sd卡下视频
public void cpAssertVideoToLocalPath() {
try {
InputStream myInput;
OutputStream myOutput = new FileOutputStream(Environment.getExternalStorageDirectory().getAbsolutePath() "/DCIM/Camera/local_video.mp4");
myInput = this.getAssets().open("local_video.mp4");
byte[] buffer = new byte[1024];
int length = myInput.read(buffer);
while (length > 0) {
myOutput.write(buffer, 0, length);
length = myInput.read(buffer);
}
myOutput.flush();
myInput.close();
myOutput.close();
} catch (IOException e) {
e.printStackTrace();
}
}
myJzvdStd.setUp(Environment.getExternalStorageDirectory().getAbsolutePath() "/DCIM/Camera/local_video.mp4", "饺子不信",Jzvd.SCREEN_WINDOW_NORMAL, );
这里很多人问为什么播不了，请认真怒url，播不了就是url没怒对播放assets目录下的视频
代码语言：javascript复制 复制Demo中CustomMediaPlayerAssertFolder类到你的项目下
----------------------------------------------------------------------------
JZDataSource jzDataSource = null;
try {
jzDataSource = new JZDataSource(getAssets().openFd("local_video.mp4"));
jzDataSource.title = "饺子快长大";
} catch (IOException e) {
e.printStackTrace();
}
jzvdStd.setUp(jzDataSource, JzvdStd.SCREEN_WINDOW_NORMAL);
Glide.with(this)
.load("http://jzvd-pic.nathen.cn/jzvd-pic/1bb2ebbe-140d-4e2e-abd2-9e7e564f71ac.png")
.into(jzvdStd.thumbImageView);
Jzvd.setMediaInterface(new CustomMediaPlayerAssertFolder());//进入此页面修改MediaInterface，让此页面的jzvd正常工作直接全屏播放
代码语言：javascript复制JzvdStd.startFullscreen(this, JzvdStd.class, VideoConstant.videoUrlList[6], "饺子辛苦了");开启小窗播放
代码语言：javascript复制mJzvdStd.startWindowTiny();列表Item划出开启小窗播放
代码语言：javascript复制 1.Listview
listView.setOnScrollListener(new AbsListView.OnScrollListener() {
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}
@Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
Jzvd.onScrollAutoTiny(view, firstVisibleItem, visibleItemCount, totalItemCount);
// Jzvd.onScrollReleaseAllVideos(view, firstVisibleItem, visibleItemCount, totalItemCount); 这是不开启列表划出小窗 同时也是画出屏幕释放JZ 划出暂停
}
});
2. RecyclerView 划出列表开启小窗
recyclerView.addOnChildAttachStateChangeListener(new RecyclerView.OnChildAttachStateChangeListener() {
@Override
public void onChildViewAttachedToWindow(View view) {
Jzvd.onChildViewAttachedToWindow(view, R.id.videoplayer);
}
@Override
public void onChildViewDetachedFromWindow(View view) {
Jzvd.onChildViewDetachedFromWindow(view);
}
});
2.1 RecyclerView划出屏幕释放JZ，同时也是不开启列表划出显示小窗
recyclerView.addOnChildAttachStateChangeListener(new RecyclerView.OnChildAttachStateChangeListener() {
@Override
public void onChildViewAttachedToWindow(View view) {
}
@Override
public void onChildViewDetachedFromWindow(View view) {
Jzvd jzvd = view.findViewById(R.id.videoplayer);
if (jzvd != null && jzvd.jzDataSource.containsTheUrl(JZMediaManager.getCurrentUrl())) {
Jzvd currentJzvd = JzvdMgr.getCurrentJzvd();
if (currentJzvd != null && currentJzvd.currentScreen != Jzvd.SCREEN_WINDOW_FULLSCREEN) {
Jzvd.releaseAllVideos();
}
}
}
});小屏播放无声音，全屏有声音
代码语言：javascript复制 创建一个类继承JzvdStd并在XML设置
public class JzvdStdVolumeAfterFullscreen extends JzvdStd {
public JzvdStdVolumeAfterFullscreen(Context context) {
super(context);
}
public JzvdStdVolumeAfterFullscreen(Context context, AttributeSet attrs) {

*/
@Override
public void playOnThisJzvd() {

}边播边缓存和清晰度切换
代码语言：javascript复制 1. 集成videocache implementation 'com.danikula:videocache:2.7.0'，并初始化

return app.proxy == null ? (app.proxy = app.newProxy()) : app.proxy;
}
private HttpProxyCacheServer newProxy() {
return new HttpProxyCacheServer(this);
}
}
2.引用
LinkedHashMap map = new LinkedHashMap();
String proxyUrl = ApplicationDemo.getProxy(this).getProxyUrl(VideoConstant.videoUrls[0][9]);
map.put("高清", proxyUrl);
map.put("标清", VideoConstant.videoUrls[0][6]);
map.put("普清", VideoConstant.videoUrlList[0]);
JZDataSource jzDataSource = new JZDataSource(map, "饺子不信");
jzDataSource.looping = true;
jzDataSource.currentUrlIndex = 2;
jzDataSource.headerMap.put("key", "value");//header
mJzvdStd.setUp(jzDataSource
, JzvdStd.SCREEN_WINDOW_NORMAL);
Glide.with(this).load(VideoConstant.videoThumbList[0]).into(mJzvdStd.thumbImageView);重复播放
代码语言：javascript复制 创建一个类集成JzvdStd并在XML设置

}
还有一种方法就是上面清晰度切换loop循环标志重力感应自动进入全屏

mSensorManager.registerListener(mSensorEventListener, accelerometerSensor, SensorManager.SENSOR_DELAY_NORMAL);
}
@Override
protected void onPause() {
super.onPause();
mSensorManager.unregisterListener(mSensorEventListener);
}重力感应
代码语言：javascript复制 Jzvd.FULLSCREEN_ORIENTATION=ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
Jzvd.NORMAL_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
两个变量控制全屏前后的屏幕方向不保存播放进度
代码语言：javascript复制Jzvd.SAVE_PROGRESS = false;取消播放时在非WIFIDialog提示
代码语言：javascript复制Jzvd.WIFI_TIP_DIALOG_SHOWED=true;清除某个URL进度
代码语言：javascript复制 Jzvd.clearSavedProgress(this, "url");切换播放内核

}相关函数回调，屏幕状态，播放器状态,事件
在继承JzvdStd之后，可以通过父类的mCurrentState，取得当前的播放状态。
- CURRENT_STATE_IDLE 未知状态，指控件被new出来之后什么都没做
- CURRENT_STATE_NORMAL 普通状态
- CURRENT_STATE_PREPARING 视频准备状态
- CURRENT_STATE_PREPARING_CHANGING_URL 播放中切换url的准备状态
- CURRENT_STATE_PLAYING 播放中状态
- CURRENT_STATE_PAUSE 暂停状态
- CURRENT_STATE_AUTO_COMPLETE 自动播放完成状态
- CURRENT_STATE_ERROR 错误状态
复写进入播放状态的函数，取得播放状态的回调
- onStateNormal 进入普通状态，通常指setUp之后
- onStatePreparing 进入准备中状态，就是loading状态
- onStatePlaying 进入播放状态
- onStatePause 进入暂停状态
- onStateError 进入错误状态
- onStateAutoComplete 进入自动播放完成状态
全屏、小窗、非全屏分别是不同的实例，在继承JzvdStd后，通过mCurrentScreen变量，取得当前屏幕类型
- SCREEN_WINDOW_NORMAL 普通窗口（进入全屏之前的）
- SCREEN_WINDOW_LIST 列表窗口（进入全屏之前）
- SCREEN_WINDOW_FULLSCREEN 全屏
- SCREEN_WINDOW_TINY 小窗
事件
- 复写onProgress函数，取得每次播放器设置底部seekBar的进度回调
- 调用changeUrl函数，切换url
- 复写onClick函数，取得各种按钮的点击事件
- 复写onTouch函数，取得全屏之后的手势操作
