饺子播放器RecyclerView自动播放
项目地址:https://github.com/AndroidLMY/JzPlayer
效果图如下
添加相关依赖
implementation 'com.google.android.material:material:1.0.0'
implementation 'androidx.recyclerview:recyclerview:1.0.0'
implementation 'cn.jzvd:jiaozivideoplayer:7.0.5'
implementation 'com.github.bumptech.glide:glide:4.8.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'
如果添加以上依赖报下面的错误
请在build中android节点下添加
compileOptions {
targetCompatibility 1.8
sourceCompatibility 1.8
}
清单文件添加网络权限
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
