android-整体UI设计-（滑动导航栏+滚动页面）

看到CSDN有这样一篇关于横滑屏的界面，是通过打包以后的组件实现的。下面是正文

很多朋友对RollNavigationBar+SlidePageView如何设计业务界面感到疑惑，今天我专门写了Demo共大家参考。效果图如下：


页面A

页面A滑向页面B中

页面B

做了个简单的动态效果图

实现源码如下：

[java] view
plaincopy

package cn.w.song.ui;



import java.util.HashMap;

import java.util.LinkedList;

import java.util.List;

import java.util.Map;



import android.app.Activity;

import android.os.Bundle;

import android.view.LayoutInflater;

import android.view.MotionEvent;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ImageView;

import android.widget.TextView;

import cn.w.song.widget.navigation.RollNavigationBar;

import cn.w.song.widget.navigation.adapter.RollNavigationBarAdapter;

import cn.w.song.widget.scroll.SlidePageView;

import cn.w.song.widget.scroll.SlidePageView.OnPageViewChangedListener;

注意demo项目务必导入w.song.android.widget-1.0.4.jar包。

w.song.android.widget.jar有了1.0.4版本，该版本没有新增组件，但对现有组件做了良好的优化。
