之前有跟大家分享设置Tab风格和Item圆角的实现，希望能给有需要的朋友一点点帮助，今天再和大家分享一下用ViewPager实现设置分页，小米和OPPO就是这样的设置，先来看看效果图：
为了帮助大家更清晰的理解，我单独拿出一个小例子，有需要的朋友可以下载下来看看：
http://git.oschina.net/way/SettingTab/tree/master
其实要实现这样的风格并不难，只要能比较深入的理解PreferenceActivity.java就可以了。我们都知道Settings.java是继承自PreferenceActivity.java，所用的布局文件layout也是父类的，而且他的二级界面都是Fragment，都是依赖他这个Activity，如果在onCreate函数中通过setContentView()改变Settings.java的布局，岂不是也会影响他的二级界面？相信很多遇到困难的朋友就是这个原因。
答案是否定的！很明显，我们只需要在显示Settings的第一个界面的时候才setContentView()，也就是说在onCreate里面判断一下： if (this.getClass().equals(Settings.class))，为什么是这样呢？我们可以滚动到Settings.java文件末尾，会发现，其实二级菜单都是一些Fragment，但是它们也有虚拟的类名的，都是Settings的内部类，所以，进到二级菜单就不满足这个条件了。
如下所示：
if (this.getClass().equals(Settings.class)) {
setContentView(R.layout.tab_settings);
mTabCursor = (ImageView) findViewById(R.id.tab_cursor);
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
viewPager.setAdapter(new ViewPagerAdapter(getFragmentManager()));
viewPager.setOnPageChangeListener(mPageChangeListener);
mViewPager = viewPager;
mTabGeneral = (TextView) findViewById(R.id.tab_general);
mTabDisplay = (TextView) findViewById(R.id.tab_display);
mTabGeneral.setOnClickListener(mTabOnClickListener);
mTabDisplay.setOnClickListener(mTabOnClickListener);
mTabGeneral.setTextColor(COLOR_SELECTED);
mTabGeneral.setTextSize(TEXT_SIZE_SELECTED);
}
相信，看完上面这段代码，遇到困难的朋友应该会豁然开朗。下面都可以不用继续看下去了。
不过为了善始善终，我会继续贴下去。
接下来，我们看看tab_settings.xml的布局，由于PreferenceActivity的特性，布局中必须要有一个id为android:id/list的ListView，因为所有的xml目录下的preference解析出来都是显示在上面，虽然我们改变了布局，但还是不能改变他的代码嘛！就弄一个高度宽度为0的ListView骗一下它就可以了，呵呵：
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ListView
android:id="@android:id/list"
android:layout_width="0dp"
android:layout_height="0dp"
android:visibility="gone"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<FrameLayout
android:layout_width="match_parent"
android:layout_height="@dimen/tab_height"
android:background="@drawable/tab_background" >
<ImageView
android:id="@+id/tab_cursor"
android:layout_width="@dimen/tab_width"
android:layout_height="@dimen/tab_height"
android:background="@drawable/tab_cursor"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="@dimen/tab_height">
<TextView
android:id="@+id/tab_general"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_gravity="center_vertical"
android:gravity="center"
android:text="@string/tab_general"
android:singleLine="true"
android:textSize="@dimen/tab_text_size" />
<TextView
android:id="@+id/tab_display"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:layout_gravity="center_vertical"
android:text="@string/tab_display"
android:singleLine="true"
android:textSize="@dimen/tab_text_size" />
</LinearLayout>
</FrameLayout>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</FrameLayout>
接下来便是普通ViewPager的使用了，我这里就不多说了。
