ScaleAnimationHelper

HomeRelativeLayout

用法：

布局中使用

      <school.zn.publib.view.RelativeLayout.HomeRelativeLayout                android:layout_width="0dp"                android:layout_height="match_parent"                android:layout_marginLeft="1dp"                android:layout_marginRight="1dp"                android:layout_weight="1.0"                android:background="@drawable/red_corners_big"                scale:scale_size="0.95" >                <TextView                    android:layout_marginTop="20dp"                    android:layout_centerHorizontal="true"                    android:layout_width="wrap_content"                    android:layout_height="wrap_content"                    android:text="考 勤"                    style="@style/Tab_Text"                 />                <ImageView                    android:layout_width="match_parent"                    android:layout_height="match_parent"                     android:src="@mipmap/common_btn_homepage_hotel"/>            </school.zn.publib.view.RelativeLayout.HomeRelativeLayout>
