Android开发长按录音

一、前言：长按录音不算太常见功能，万一你刚好需要呢。

二、效果图：

三、解决思路

主要用的是MediaRecorder，可能你百度MediaRecorder，就知道怎么做了，不过有些细节需要自己处理。

四、给长按的全部代码

private val mOnVoiceBtnTouchListener =
    OnTouchListener { v, event ->
        if (mBinding.tvClickPlay.visibility == View.VISIBLE){
            return@OnTouchListener false
        }
        val mOffsetLimit = 70 * v.context.resources.displayMetrics.density
        //val permissions = arrayOf(Manifest.permission.RECORD_AUDIO)
        if (!PermissionCheckUtil.checkPermissions(v.context, PermissionAppUtils.Group.RECORD_AUDIO_STORAGE)
            && event.action == MotionEvent.ACTION_DOWN
        ) {
            DialogUtils.okAndCancel(mContext, getString(R.string.record_audio_permission_tip) , ok = getString(R.string.go_open), okListener = {
                    PermissionAppUtils.requestCombinedPermission(mContext,
                        PermissionAppUtils.Group.RECORD_AUDIO_STORAGE) {
                        if (it.granted){

                        } else  {
                            if (it.shouldShowRequestPermissionRationale){
