调用Handler()方法的Deprecated warning

问题

使用Hnadler()时报Deprecated warning

 Handler().postDelayed({
        context?.let {
           //code
        }
    }, 3000)

解决

Java

new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {
        @Override
        public void run() {
            // Your Code
        }
    }, 3000);

Kotlin

Handler(Looper.getMainLooper()).postDelayed({
            {
                //Your Code
            }
        }, 3000)
