赵雅智_名片夹(6)_仿微信底导航栏,赵雅智导航栏

效果图如下

使用TabHost布局,并使用单选按钮组和FrameLayout相结合

布局文件代码:

<RelativeLayout xmlns:凤凰娱乐网址android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TabHost
        android:id="@android:id/tabhost"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

        <LinearLayout
            android:layout_width="fill_parent"

Acyivity代码:

		super.onCreate(savedInstanceState);

		super.onDestroy();
	}
}

按钮按下效果:

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

    <item android:drawable="@drawable/daohang_cards" android:state_checked="false"/>
    <item android:drawable="@drawable/daohang_cards_put" android:state_checked="true"/>

</selector>

背景按下效果
