RelativeLayout :相对布局,这是最自由的布局,开发者可以自己配置控件的位置。 RelativeLayout 有几个重要的属性: 第一类 : 属性值为 true 或 false android:layout_centerHrizontal 水平居中 android:layout_centerVertical 垂直居中 android:layout_centerInparent 相对于父元素完全居中 android:layout_alignParentBottom 贴紧父元素的下边缘 android:layout_alignParentLeft 贴紧父元素的左边缘 android:layout_alignParentRight 贴紧父元素的右边缘 android:layout_alignParentTop 贴紧父元素的上边缘 android:layout_alignWithParentIfMissing 如果对应的兄弟元素找不到的话就以父元素做参照物 第二类:属性值必须为 id 的引用名 “@id/id-name” android:layout_below 将该控件的顶部至于给定 ID 的控件之下 android:layout_above 将该控件的底部至于给定 ID 的控件之上 android:layout_toLeftOf 在某元素的左边 android:layout
