代码说明：
2.1.1 第一个RelativeLayout为图一上的实现代码。注意使用了一个View，也就是一条横线，令其居中布局；"地址："的TextView通过layout_alignParentLeft和layout_alignParentTop令其在整个RelativeLayout顶左顶上；"账号信息："的TextView通过layout_below令其位于横线下方，layout_alignLeft令其与"地址："的TextView左边对齐，然后用layout_alignParentBottom让其居于容器底部。
2.1.2 第二个RelativeLayout为图一下的实现代码。关键是vVDivider1和vVDivider2，与3.1.1类似，画出了一个十字架的布局，然后分别用居左、居上、居下、居右等方式实现了该布局效果。
2.2 实现 图二 效果代码
<
RelativeLayout
android:id
="@+id/rlpb"
android:layout_width ="fill_parent" android:background ="#ffeff0f4"
android:visibility ="gone" android:layout_height ="fill_parent"
android:layout_weight ="1.0" >
< LinearLayout android:layout_centerInParent ="true"
android:layout_width ="wrap_content" android:layout_height ="wrap_content" >
< ProgressBar android:id ="@+id/prb"
style ="?android:attr/progressBarStyleSmallTitle"
android:layout_width ="wrap_content" android:layout_height ="wrap_content" />
< TextView android:text ="@string/loadinfo"
android:layout_width ="wrap_content" android:layout_height ="wrap_content" />
</ LinearLayout >
</ RelativeLayout >
android:layout_width ="fill_parent" android:background ="#ffeff0f4"
android:visibility ="gone" android:layout_height ="fill_parent"
android:layout_weight ="1.0" >
< LinearLayout android:layout_centerInParent ="true"
android:layout_width ="wrap_content" android:layout_height ="wrap_content" >
< ProgressBar android:id ="@+id/prb"
style ="?android:attr/progressBarStyleSmallTitle"
android:layout_width ="wrap_content" android:layout_height ="wrap_content" />
< TextView android:text ="@string/loadinfo"
android:layout_width ="wrap_content" android:layout_height ="wrap_content" />
</ LinearLayout >
</ RelativeLayout >
代码说明：
主要是layout_centerInParent属性的应用，令其居于RelativeLayout的中间。使用的时候领ListView先隐藏，然后让这个布局显示并填充，用完在设置Visible为GONE即可。
三、总结
熟练掌握以下重要属性，并灵活运用：
android:layout_centerInParent 居中布局
android:layout_centerVertical 水平居中布局
android:layout_centerHorizontal 垂直居中布局
android:layout_centerVertical 水平居中布局
android:layout_centerHorizontal 垂直居中布局
android:layout_alignParentTop 居于容器内顶部
android:layout_alignParentBottom 居于容器内底部
android:layout_alignParentLeft 居于容器内左边
android:layout_alignParentRight 居于容器内右边
android:layout_above 居于指定View的上方
android:layout_below 居于指定View的下方
android:layout_toRightOf 在指定View的右边
android:layout_toLeftOf 在指定View的左边
android:layout_alignTop 与指定View的Top一致
android:layout_alignParentBottom 居于容器内底部
android:layout_alignParentLeft 居于容器内左边
android:layout_alignParentRight 居于容器内右边
android:layout_above 居于指定View的上方
android:layout_below 居于指定View的下方
android:layout_toRightOf 在指定View的右边
android:layout_toLeftOf 在指定View的左边
android:layout_alignTop 与指定View的Top一致
