第一種寫法
var mStartVideoHandler: Handler = Handler()
var mStartVideoRunnable: Runnable =object: Runnable {
override funrun() {
mStartVideoHandler.postDelayed(this,10000)
}
}
第二種：
private lateinit varrunnalble:Runnable
init{
runnalble=Runnable{
mStartVideoHandler.postDelayed(runnalble,10000)
}
}
第三種 自己賦值給自己
?? private fun mStartVideoRunnable() = mStartVideoRunnable
