自定义view实现如下效果
衣服图与设计图叠加，显示在列表中
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec,heightMeasureSpec);
int widthSize = MeasureSpec.getSize(widthMeasureSpec);
int widthMode = MeasureSpec.getMode(widthMeasureSpec);
int heightSize = MeasureSpec.getSize(heightMeasureSpec);
int heightMode = MeasureSpec.getMode(heightMeasureSpec);

    if (widthMode == MeasureSpec.EXACTLY && heightMode == MeasureSpec.AT_MOST){        heightSize = widthSize *5 / 4;        setMeasuredDimension(widthSize,heightSize);    }else if (widthMode == MeasureSpec.AT_MOST && heightMode == MeasureSpec.EXACTLY){        widthSize = heightSize *4 /5;        setMeasuredDimension(widthSize,heightSize);    }else{        widthSize = getMeasuredWidth();        heightSize = widthSize *5 / 4;    }    setDesignPosition(widthSize,heightSize,type);}public void setDesignPosition(int w,int h,int type){    ViewGroup.LayoutParams params = simpleDraweeView_clothes.getLayoutParams();    params.width = w;    params.height = h;    simpleDraweeView_clothes.setLayoutParams(params);    if(type == CommonConstants.TShit){        //T恤        LayoutParams param = (LayoutParams) simpleDraweeView_design.getLayoutParams();        int l = (int) ((w - 0.371 * w)/2);        int t = (int) ((h - 0.414 * h)/2);        int width = (int) (0.371 * w);        int height = (int) (0.414 * h);        param.setMargins(l, t, 0, 0);        param.height = height;        param.width = width;        simpleDraweeView_design.setLayoutParams(param);    }}
