本文主要是介绍高仿秘密初次安装启动引导界面，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
今天闲来无事，就把无秘的app给反编译了，然后简单的模仿了一下开机引导界面，废话不多说了，直接开始吧。
首先，先看一下布局文件，这里没有使用比较火的Android-ViewPagerIndicator,直接使用viewpager+四个圆圈图标来实现。布局如下：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:vpi="http://schemas.android.com/apk/res-auto"android:layout_width="fill_parent"android:layout_height="fill_parent"android:background="@drawable/account_guidance_bg" ><android.support.v4.view.ViewPagerandroid:id="@+id/view_pager"android:layout_width="fill_parent"android:layout_height="fill_parent" /><LinearLayoutandroid:id="@+id/layout_button"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_alignParentBottom="true"android:paddingBottom="30.0dip"android:paddingLeft="20.0dip"android:paddingRight="20.0dip" ><Buttonandroid:id="@+id/bt_register"style="?android:attr/buttonBarButtonStyle"android:layout_width="0.0dip"android:layout_height="wrap_content"android:layout_marginRight="15.0dip"android:layout_weight="1.0"android:background="@drawable/green_btn_bg"android:text="立即加入"android:textColor="@android:color/white" /><Buttonandroid:id="@+id/bt_login"style="?android:attr/buttonBarButtonStyle"android:layout_width="0.0dip"android:layout_height="wrap_content"android:layout_weight="1.0"android:background="@drawable/white_translucent_btn_bg"android:text="登录"android:textColor="@android:color/white" /></LinearLayout><LinearLayoutandroid:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_above="@id/layout_button"android:layout_gravity="bottom"android:layout_marginBottom="40dp"android:gravity="center"android:orientation="horizontal" ><ImageViewandroid:id="@+id/miv_01"android:layout_width="12dp"android:layout_height="12dp"android:layout_margin="4dp"android:src="@drawable/tuitional_carousel_btn" /><ImageViewandroid:id="@+id/miv_02"android:layout_width="12dp"android:layout_height="12dp"android:layout_margin="4dp"android:src="@drawable/tuitional_carousel_active_btn" /><ImageViewandroid:id="@+id/miv_03"android:layout_width="12dp"android:layout_height="12dp"android:layout_margin="4dp"android:src="@drawable/tuitional_carousel_active_btn" /><ImageViewandroid:id="@+id/miv_04"android:layout_width="12dp"android:layout_height="12dp"android:layout_margin="4dp"android:src="@drawable/tuitional_carousel_active_btn" /></LinearLayout></RelativeLayout>package com.happy.guide;import java.util.ArrayList;

是不是挺简单呢，肯定还有比这更好的写法，简单先这么实现吧，后续再进行优化
