Question

如何到到ExpandableListView 的groupposition和childposition

Answer 1

getChildView方法有传入groupPosition和childPosition吧，如楼上所说，给button setTag保存两个position，在点击事件里getTag取出来，传给你的回调。类似：

getChildView(int groupPosition, int childPosition, ...) {
button.setTag(TAG_GROUP, groupPosition);
button.setTag(TAG_CHILD, childPosition);
button.setOnClickListener(new View.OnClickListener {
onClick(View view) {
int gp = view.getTag(TAG_GROUP)；
int cp = view.getTag(TAG_CHILD);
yourCallback.callBack(gp, cp, ...);
}
});
}
