ExoPlayer简单使用

ExoPlayer非最新版使用

添加依赖

api 'com.google.android.exoplayer:exoplayer:2.12.1'

//初始化播放器

    fun initPlayer() {

xml布局文件：

<com.google.android.exoplayer2.ui.PlayerView
    android:id="@+id/player_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:controller_layout_id="@layout/playbackcontrol_view"
  />

自定义UI：playbackcontrol_view.xml

控件id不可更改 其余属性随便更改
