二、思路分析

叠加肯定用到FrameLayout,因为数量不一定，就需要动态addView。然后

headParams.leftMargin来设置偏移量

三、案例关键代码：

xml

android:layout_width="match_parent"

android:layout_height="match_parent"

android:background="@drawable/white_circle"

>

android:id="@+id/iv_head_small"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:layout_margin="1dp"

android:scaleType="centerCrop" />

java代码：

for (i in dataBean.user_items.indices) {

val headParams = FrameLayout.LayoutParams(UtilHelper.dip2px(mActivity, 26f), UtilHelper.dip2px(mActivity, 26f))

val headGroupView = UtilHelper.inflate(mActivity!!, R.layout.layout_ceo_data_head)

headParams.leftMargin = (dataBean.user_items.size - i - 1) * UtilHelper.dip2px(mActivity, 20f)

headGroupView.layoutParams = headParams

val headView = headGroupView.findViewById(R.id.iv_head_small)

GlideHelper.load(mActivity!!, dataBean.user_items[i].img!!, headView, 7)

fl_user_heads?.addView(headGroupView)

}

关键是headParams.leftMargin思路
