Java 如何访问linearLayout的所有子级？

我在线性布局中有图像视图。我试图在单击其父对象（linearlayout）时获取所有ImageView（子对象）。您能告诉我单击linearlayout时如何访问linearlayout的所有子项吗

试试这段代码

       LinearLayout ll =findViewById(R.id.linear);
    final int childCount = ll.getChildCount();
    for (int i = 0; i < childCount; i++) {
        View v = ll.getChildAt(i);
    }

LinearLayout ll=findviewbyd（R.id.linear）；
final int childCount=ll.getChildCount（）；
for（int i=0；i

请详细说明您想要实现的目标。看起来您在询问之前并没有搜索过，但您必须这样做。
