1，先上效果图：
2，介绍：
播放控件使用Android自带的 VideoView 控件。控制器为自定义View以及控制器： 主要代码：
主界面 分为 三个部分： 头部 底部 播放器部分：
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.daemon.viewlp.MainActivity"> <include android:id="@+id/title_view" layout="@layout/include_title_bar" /> <RelativeLayout android:id="@+id/player_parent" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#000000" android:gravity="center_vertical" android:paddingBottom="2dp" android:paddingTop="2dp"> <com.daemon.viewlp.view.widgets.VideoView android:id="@+id/paly_video" android:layout_width="fill_parent" android:layout_height="200dp" /> </RelativeLayout> <LinearLayout android:id="@+id/contentView" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:background="#ddf" > <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:text="otherContent" /> </LinearLayout></LinearLayout>博主的横竖屏适配 通过点击事件 请求横竖屏，横屏时隐藏掉头部底部，设置播放器布局参数为填充整个屏幕，竖屏时恢复原状。
自己封装了个 player 器 管理类 MmediaController：

mmediaController = new MmediaController(this) .setTitleBar(titleView) .setPlayerParent(playerParent) .setPlayer(player) .setContentView(contentView) .build();//下面是 横竖屏 切换 @SuppressLint("NewApi") @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); boolean tag = getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE ? false : true; mmediaController.switchOrientation(tag); fullScreen(!tag ? true : false); }横竖屏切换再配置文件添加代码：
android:configChanges="orientation|keyboardHidden|screenSize" android:label="@string/app_name">以及 添加权限：
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />简单实现播放器播放，不过博主的 进度条在拖动时 有些卡顿，有解决的朋友希望可以说下。
