現在的APP大部分首頁打開時的歡迎界面都有廣告，倒計時結束進入主界面，以及點擊跳過廣告直接進入，以前小小實現了一下，趁今天有時間，傳上來給大家分享，歡迎大家一起學習，主要用到有： Intent：意圖，實現頁面跳轉 CountDownTimer：倒計時器，首先咱看圖： 111

倒計時完自動跳指定Activity，也可以跳過廣告，下面直接上完整代碼 首先布局文件：

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" > <ImageView android:layout_width="match_parent" android:layout_height="match_parent" android:src="@drawable/aa" android:id="@+id/image_ss" android:scaleType="fitXY" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="right" android:id="@+id/text_time" android:textSize="20sp" /></FrameLayout>

下面SplashActivity:
