请用一个外形用params关键词构造,类名是MultiShape,VIewGroup形参名是v，child是要插入的子视图,insets是其四个边缘插入的值{t(上)，l（左）,b（下）,r(右）}}的java构造方法
user
```java
public MultiShape(ViewGroup v, View child, int[] insets) {
    this.viewGroup = v;
    this.childView = child;
    this.topInsets = insets[0];
    this.leftInsets = insets[1];
    this.bottomInsets = insets[2];
    this.rightInsets = insets[3];
}
