[移动开发]JZVideo之非自定义，直接修改UI

一、环境搭建

? ? ? ? 1、JZ主依赖，版本7.7

implementation 'cn.jzvd:jiaozivideoplayer:7.7.0'

?2、如果需要切换解码内核则需导入别的依赖

   //阿里内核
    implementation 'com.aliyun.sdk.android:AliyunPlayer:4.5.0-full'
    implementation 'com.alivc.conan:AlivcConan:0.9.5'
    //IJKPlayer解析
    implementation 'tv.danmaku.ijk.media:ijkplayer-java:0.8.8'
    implementation 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.4'
    //EXo内核
    implementation 'com.google.android.exoplayer:exoplayer:2.12.1'

注意：阿里内核必须依赖AlivcConan否则会报如下错误

 java.lang.UnsatisfiedLinkError: dlopen failed: library "libalivc_conan.so" not found

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:967)

二、常用一些设置

1、设置切换内核，我这里是阿里云的内核

mJzvdStd.setMediaInterface(JZMediaAliyun::class.java)

2、设置视频封面，这里源代码已经直接提供了控件，直接加载图片地址就好

 mJzvdStd.posterImageView

3、修改进度条，修改UI尽量在changeUiToNormal中完成，但有的多状态的可能不行

    override fun changeUiToNormal() {
        super.changeUiToNormal()
        LogUtil.d("changeUiToNormal")
        //修改进度条
        progressBar.thumb=context.getDrawable(R.drawable.seek_bar_thumb)
    }

? ? 4、修改播放、暂停、重播样式

   override fun updateStartImage() {
        if (state == STATE_PLAYING) {
            startButton.visibility = VISIBLE
            //暂停样式
            startButton.setImageResource(R.drawable.jz_click_pause_selector)
            replayTextView.visibility = GONE
        } else if (state == STATE_ERROR) {
            startButton.visibility = INVISIBLE
            replayTextView.visibility = GONE
        } else if (state == STATE_AUTO_COMPLETE) {
            startButton.visibility = VISIBLE
            //重新播放样式
            startButton.setImageResource(R.drawable.jz_click_replay_selector)
            replayTextView.visibility = VISIBLE
        } else {
            //播放样式
            startButton.setImageResource(R.mipmap.qq)
            replayTextView.visibility = GONE

        }
    }

5、修改全屏按钮和非全屏按钮

 override fun setScreenNormal() {
        super.setScreenNormal()
        //非全屏展示按钮
        fullscreenButton.setImageResource(R.mipmap.qq)
    }

    override fun setScreenFullscreen() {
        //全屏展示按钮
        super.setScreenFullscreen()
    }

6、如果要监听准确开始则需要startvideo方法

    override fun startVideo() {
        super.startVideo()
        LogUtil.d("开始播放-这里可以做一些播放量统计之类的工作")
    }

三、注意

1、修改UI时候尽量新建一个类继承JzvdStd方法，在其中重写对应的方法

2、修改内核的时候对应的类，需要从饺子源码中复制过去
