一、前言

類似微信視頻通話中點(diǎn)擊小窗口時企巢，本地視頻和遠(yuǎn)端視頻切換枫慷。可惜這簡單的功能聲網(wǎng)SDK也是沒有提供包斑，得自己做流礁，好在也不難。

二罗丰、先看下設(shè)計(jì)圖

三神帅、解決思路

本地視頻和遠(yuǎn)端視頻各聲明一個SurfaceView，互換時就把它們add到對應(yīng)的FrameLayout里面萌抵。

四找御、示例代碼

private fun setupLocalVideo(isCloseCamera:Boolean,fl:FrameLayout? = mBinding.flVideoCallLocalVideo) {
    LogUtils.i("setupLocalVideo","setupLocalVideo")
    if (isMBindingViewInitialised()){
        fl?.let {
            if (isCloseCamera){
                it.removeAllViews()
                it.addView(LayoutInflater.from(mContext).inflate(R.layout.layout_close_local_video,it,false))
            } else {
                it.removeAllViews()
                surfaceViewLocal = null
                surfaceViewLocal = RtcEngine.CreateTextureView(mContext)
                mVideoManager?.setLocalPreview(surfaceViewLocal)
                //surfaceViewLocal!!.setZOrderMediaOverlay(true)
                it.addView(surfaceViewLocal)
                // Initializes the local video view.
                // RENDER_MODE_FIT: Uniformly scale the video until one of its dimension fits the boundary. Areas that are not filled due to the disparity in the aspect ratio are filled with black.
                //rtcEngine?.setupLocalVideo(VideoCanvas(surfaceViewLocal, VideoCanvas.RENDER_MODE_HIDDEN, SPUtil.getUserId()))
                surfaceViewLocal?.tag = SPUtil.getUserId()

            }
        }

        
    }
}



private fun setupRemoteVideo(uid: Int,fl: FrameLayout? = mBinding.flVideoCallRemoteVideo,surfaceViewRemote1:SurfaceView? = null) {
    if (isMBindingViewInitialised()){
        fl?.let {
            if (it.childCount >= 1) {
                return
            }
            it.removeAllViews()
            if (surfaceViewRemote1 == null){
                surfaceViewRemote = RtcEngine.CreateRendererView(mContext)
                it.addView(surfaceViewRemote)
                // Initializes the video view of a remote user.
                rtcEngine?.setupRemoteVideo(VideoCanvas(surfaceViewRemote, VideoCanvas.RENDER_MODE_HIDDEN, uid))
                surfaceViewRemote!!.tag = uid // for mark purpose
            } else {
                surfaceViewRemote = surfaceViewRemote1
                it.addView(surfaceViewRemote)
                surfaceViewRemote!!.tag = uid
            }
        }
    }
}

mBinding.flVideoCallLocalVideo.setOnClickListener {
        if (!mBinding.tvChatVideoAcceptingCameraClose.isSelected && surfaceViewLocal != null && surfaceViewRemote != null) {

            if (localViewSmall) {
                mBinding.flVideoCallRemoteVideo.removeView(surfaceViewRemote)
                mBinding.flVideoCallLocalVideo.removeView(surfaceViewLocal)

                mBinding.flVideoCallRemoteVideo.removeAllViews()
                mBinding.flVideoCallRemoteVideo.addView(surfaceViewLocal)
                mVideoManager?.setLocalPreview(surfaceViewLocal) //每次給了其他控件，需要調(diào)這個方法
                mBinding.flVideoCallLocalVideo.removeAllViews()
                mBinding.flVideoCallLocalVideo.addView(surfaceViewRemote)
                localViewSmall = false
            } else {
                mBinding.flVideoCallRemoteVideo.removeView(surfaceViewLocal)
                mBinding.flVideoCallLocalVideo.removeView(surfaceViewRemote)

                mBinding.flVideoCallRemoteVideo.removeAllViews()
