android客户端学习-RelativeLayout布局动态在四个角的位置增加标签

目前公司有一个商品图片动态增加标签的功能，标签为四张图片，根据不同的设置放在RelativeLayout四个角上

布局样式：

<RelativeLayout    android:id="@+id/img_rel"    android:layout_width="90dp"    android:layout_height="90dp"    android:layout_alignParentLeft="true"    android:layout_marginLeft="10dp"    android:layout_marginTop="5dp"    android:layout_marginBottom="5dp">    <ImageView        android:id="@+id/img"        android:layout_width="90dp"        android:layout_height="90dp"        android:scaleType="fitXY"        /></RelativeLayout>

页面调用：

if (promoListVo.getTags()!=null&&promoListVo.getTags().size()>0){    ViewHelperUtils.addProductTags(90,90,promoListVo.getTags(),context,bitmapUtils,viewHolder.img_rel);}
共用类及方法：
public class ViewHelperUtils {    /**     * 给商品添加标签     * @param parentWidth 增加标签布局的宽度     * @param parentHeight 增加标签布局的高度     * @param tagsVoList 标签列表     * @param context     * @param bitmapUtils     * @param relativeLayout 增加标签的布局对象     */    public static void addProductTags(int parentWidth, int parentHeight, List<EMLayoutModulesTagsVo> tagsVoList, Context context, BitmapUtils bitmapUtils,RelativeLayout relativeLayout){        for (LayoutModulesTagsVo tagsVo : tagsVoList){            int tagwidth = (int) (tagsVo.getWidthProportion()*(parentWidth/100.00));// 宽度            int tagheight = (int) (tagsVo.getHeightProportion()*(parentHeight/100.00));// 高度            // 两者取最小保持一致            if (tagwidth>tagheight){                tagwidth = tagheight;            }            if (tagsVo.getPositionType().equals("LeftTop")){// 左上角                RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(                        tagwidth,                        tagheight                );                ImageView img = new ImageView(context);                img.setLayoutParams(p);                bitmapUtils.display(img,tagsVo.getTagImageUrl());                relativeLayout.addView(img);            }else if(tagsVo.getPositionType().equals("RightTop")){// 右上角                RelativeLayout.LayoutParams p2 = new RelativeLayout.LayoutParams(                        tagwidth,                        tagheight                );                p2.addRule(RelativeLayout.ALIGN_PARENT_TOP);                p2.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);                ImageView img2 = new ImageView(context);                //设置图片的位置                img2.setLayoutParams(p2);                bitmapUtils.display(img2,tagsVo.getTagImageUrl());                relativeLayout.addView(img2);            }else if(tagsVo.getPositionType().equals("LeftBottom")){// 左下角                RelativeLayout.LayoutParams p3 = new RelativeLayout.LayoutParams(                        tagwidth,                        tagheight                );                p3.addRule(RelativeLayout.ALIGN_PARENT_LEFT);                p3.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);                ImageView img3 = new ImageView(context);                //设置图片的位置                img3.setLayoutParams(p3);                bitmapUtils.display(img3,tagsVo.getTagImageUrl());                relativeLayout.addView(img3);            }else if(tagsVo.getPositionType().equals("RightBottom")){// 右下角                RelativeLayout.LayoutParams p4 = new RelativeLayout.LayoutParams(                        tagwidth,                        tagwidth                );                p4.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);                p4.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);                ImageView img4= new ImageView(context);                //设置图片的位置                img4.setLayoutParams(p4);                bitmapUtils.display(img4,tagsVo.getTagImageUrl());                relativeLayout.addView(img4);            }        }    }}
