Android倒计时控件 Splash界面5秒自动跳转

概述Android倒计时控件 Splash界面5秒自动跳转 现在很多app的首页都有一个倒计时控件,比如说3秒或者5秒自动跳转界面,或者点击控件直接跳过 首先,自定义控件CircleProgressbar(参考网上资料) package com.zhoujian.mykeep.view; import android.annotation.TargetApi; import android.content.Context; import android.content.res.ColorStateList; import android.content.
