九宫格菜单布局

这里要介绍一下制作九宫格菜单的两种方法：

第一种就是直接使用布局文件。在ScrollView中嵌套Button即可，这种做法适用于按钮位置不变，功能固定的情况。

第二种使用的是GridView，通过设置数据源来动态生成布局，这种做法灵活性比较大，适用于功能不固定的情况，比如用户的权限不够的时候，设置某些按钮不可见等。

我将这两种做法整理到一个Demo中。下面是效果图：

下面先介绍第一种做法 （使用布局文件）的主要代码：

布局文件activity_common.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

        android:background="@drawable/bg_title_bar"

使用GridView的做法：

        android:background="@drawable/bg_title_bar"
        android:gravity="center_vertical" >

        <Button
            android:id="@+id/btn_logout"
            android:layout_width="70dip"
            android:layout_height="wrap_content"

            android:text="@string/more"
            android:textColor="@color/title_button_color_gray" />
    </RelativeLayout>

    <TextView
        android:id="@+id/tv_add"
        android:layout_width="fill_parent"
