ViewFlipper viewFlipper viewflipper ViewFlow viewpager Viewpager ViewPager

开篇

        首页只是作为ViewPager，ViewFlipper，ViewFlow的入口，提供三个Button进行跳转。

              

1. ViewPager

        先看看官方文档怎么介绍ViewPager的：http://developer.android.com/reference/android/support/v4/view/ViewPager.html

        继承关系如下：

        java.lang.Object

             android.view.View

                   android.view.ViewGroup

                        android.support.v4.view.ViewPager

        ViewPager做为容器类，可以结合View（Layout）和Fragment（Android 3.0 才引入的），官方文档说ViewPager+Fragment配合使用更好。ViewPager不在android sdk 自带jar包中，来源google 的补充组件android-support-v4.jar，没有的话可以通过eclipse下载和自己下载再添加到相应的工程中，本例用的是android-support-v13.jar，完全兼容android-support-v4.jar，看看android-support-v13.jar的目录结构：

[android-support-v13.jar下载]

         切入正题，ViewPager用法如下：

配置文件：viewpager_layout.xml:

[java] view plain copy print ?

1. <?xml version="1.0" encoding="utf-8"?>  
2. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
3.     android:layout_width="match_parent"  
4.     android:layout_height="match_parent" >  
5.       
6.     <android.support.v4.view.ViewPager  
7.         android:id="@+id/viewpager"  
8.         android:layout_width="fill_parent"  
9.         android:layout_height="wrap_content" />  
10.   
11. </RelativeLayout>  

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    
    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

</RelativeLayout>

源文件如下ViewPagerActivity.java如下：

            private final Class<?> clazz;
            private final Bundle bundle;
            Fragment fragment;

            TabInfo(Class<?> clazz, Bundle bundle) {
                this.clazz = clazz;
                this.bundle = bundle;
            }
        }

    }

}

        里面用到的FirstFragment，SecondFragment，ThreeFragment，FourFragment分别继承Fragment，运行效果如下：

        第一个就弄里个TextView，复杂的界面开发者任由发挥了，第二个和第四个都是ListView，第三个ExpandableListView，ListView的使用难点就是写适配器咯，本例是继承BaseAdapter的。ExpandableListView需要一个继承BaseExpandableListAdapter的适配器[不会的请看：ExpandableListView用法]。

2.ViewFlipper

        ViewFilpper控件是系统自带控件之一，主要为在同一个屏幕间的切换及设置动画效果，且可以自动播放，用法如下：

配置文件：viewflipper_layout.xml

[java] view plain copy print ?

1. <?xml version="1.0" encoding="utf-8"?>  
2. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

13.         android:flipInterval="2000" >  
14.   
15.         <include layout="@layout/viewflipper_one_layout" />  
16.   
17.         <include layout="@layout/viewflipper_two_layout" />

20.   
21.         <include layout="@layout/viewflipper_four_layout" />  
22.   
23.         <include layout="@layout/viewflipper_five_layout" />  
24.     </ViewFlipper>  
25.

30.         android:layout_height="wrap_content"  
31.         android:layout_marginBottom="25dip"  
32.         android:gravity="center_horizontal"  
33.         android:layout_alignParentBottom="true"  
34.         xyz:cell_width="@dimen/indicator_width"  
35.         xyz:cell_height="@dimen/indicator_height" />  
36.     -->  
37.   
38. </RelativeLayout>  

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:xyz="http://schemas.android.com/apk/res/com.xyz.vvv"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ViewFlipper
        android:id="@+id/viewflipper"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:inAnimation="@anim/slide_in"
        android:outAnimation="@anim/slide_out"
        android:flipInterval="2000" >

        <include layout="@layout/viewflipper_one_layout" />

        <include layout="@layout/viewflipper_two_layout" />

        <include layout="@layout/viewflipper_three_layout" />

        <include layout="@layout/viewflipper_four_layout" />

        <include layout="@layout/viewflipper_five_layout" />
    </ViewFlipper>

    <!--  
    <com.xyz.vvv.PageControlView
        android:id="@+id/viewflipper_indicator"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="25dip"
        android:gravity="center_horizontal"
        android:layout_alignParentBottom="true"
        xyz:cell_width="@dimen/indicator_width"
        xyz:cell_height="@dimen/indicator_height" />
    -->

</RelativeLayout>

        被注释的部分是指示器，那五个layout里都是一个ImageView，本例图片中画有指示器，PageControlView就不需要啦。

       android:autoStart="true" <<==>> mViewFlipper.startFlipping();  //自动播放

       android:flipInterval="2000" <<==>>mViewFlipper.setFilpInterval(2000);  //设置View之间切换的时间间隔

       android:inAnimation="@anim/slide_in", android:outAnimation="@anim/slide_out" 对应方法：mViewFlipper.setInAnimation，

              mViewFlipper.setOutAnimation。

图片太宽了，还有一张没加进来（图片来自手机QQ）。

         这是ViewFlipper静态加载View，动态加载View请看：ViewFlipper动态加载View

 

3.ViewFlow

        Viewflow 是 Android 平台上一个视图切换的效果库，非标准的得自己下载。ViewFlow 相当于 Android UI 部件提供水平滚动的 ViewGroup，使用 Adapter 进行条目绑定。这个拿来主义 ^-^

           按图说话吧：  带圆点的指示器。

        ViewFlow还有其他几个例子，个人觉得用的不多，就不贴啦，感兴趣的可以下载下来研究下。
