如何在android内部搜索控件下的子控件

Answer 1

* 遍历所有view
*
* @param viewGroup
*/
public void traversalView(ViewGroup viewGroup) {
int count = viewGroup.getChildCount();
for (int i = 0; i < count; i++) {
View view = viewGroup.getChildAt(i);
if (view instanceof ViewGroup) {
traversalView((ViewGroup) view);
} else {
doView(view);
}
}
}

/**
* 处理view
*
* @param view
*/
private void doView(View view) {
}

Answer 2

先通过getChildAt(int index)获取到子控件，再通过lp = getLayoutParams()获取到子控件的参数，lp.leftMargin就是你想要的数值

View child = getChildAt(0);

MarginLayoutParams lp = (MarginLayoutParams) child.getLayoutParams();

int leftMargin = lp.leftMargin
