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
>
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_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
