<span style="font-size:15px;">android布局的目的是为了实现不同屏幕比例适配而设计的，有五种布局类：FrameLayout、LinearLayout、AbsoluteLayout、RelativeLayout和TableLayout。五大布局类的继承关系如下（以FrameLayout为例）：</span> <p><a

style="font-family:Georgia;"><code>android:layout_gravity</code>来指定子类视图的位置。同一位置的子类视图处于层叠状，最上面的子类视图是最后添加的子类视图。</span></span></p> <p> 继承关系如下<span style="font-size:x-small;">：</span></p> <p><a
