启动页的
activity_splash.xml
我用了一张图片自己添加吧
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/activity_splash" tools:context=".SplashActivity" android:theme="@android:style/Theme.NoTitleBar.Fullscreen" android:background="@mipmap/diyi"> </RelativeLayout>
manifest 定义

//把那个MainActivity设置为栈底 意思就是防止你按返回键的时候返回到哪个启动欢迎界面
startActivity(intent);//载入主窗口

安卓studio 遇到的问题 ，eclipse下取消标题栏的问题再安卓studio下无法取消 ，以及点击返回按钮 会返回到启动页面的问题 例子中都已经解决
