饺子播放器RecyclerView自动播放

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
