例外資訊，小白只能看明白越界了，但不知道哪里影響的

getChildView方法
@Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
int type = getChildType(groupPosition, childPosition);
switch (type) {
case TYPE_1:
ViewHolderItem itemHolder;
if (convertView == null) {
convertView = LayoutInflater.from(mcontext).inflate(R.layout.item_formentry_view, parent, false);
itemHolder = new ViewHolderItem();
itemHolder.tv_view_name = convertView.findViewById(R.id.tv_view_name);
convertView.setTag(itemHolder);
} else {
itemHolder = (ViewHolderItem) convertView.getTag();
}
itemHolder.tv_view_name.setText(miData.get(groupPosition).get(childPosition).getRecordItem());
View finalConvertView = convertView;
convertView.setOnClickListener(v -> mlistener.onItemClick(finalConvertView, groupPosition, childPosition));
break;
case TYPE_2:
ViewHolderItem2 itemHolder2;
if (convertView == null) {
convertView = LayoutInflater.from(mcontext).inflate(R.layout.item_view_radiobtn, parent, false);
itemHolder2 = new ViewHolderItem2();
itemHolder2.tv_radiobtn_name = convertView.findViewById(R.id.tv_radiobtn_name);
itemHolder2.rbtn_N = convertView.findViewById(R.id.rbtn_N);
itemHolder2.rbtn_Y = convertView.findViewById(R.id.rbtn_Y);
convertView.setTag(itemHolder2);
} else {
itemHolder2 = (ViewHolderItem2) convertView.getTag();
}
itemHolder2.rbtn_Y.setChecked(true);
itemHolder2.tv_radiobtn_name.setText(miData.get(groupPosition).get(childPosition).getRecordItem());
View finalConvertView2 = convertView;
convertView.setOnClickListener(v -> mlistener.onItemClick(finalConvertView2, groupPosition, childPosition));
itemHolder2.rbtn_N.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(mcontext, "不合格", Toast.LENGTH_SHORT).show();
}
});
break;
}
return convertView;
}
getChildType和getGroupTypeCount方法，不理解getGroupTypeCount應回傳什么，每次例外越界的index總是該方法回傳的值 +1
@Override
public int getChildType(int groupPosition, int childPosition) {
try {
if (mgData.get(groupPosition).getgName().equals("基本資訊")) {
return TYPE_1;
} else if (mgData.get(groupPosition).getgName().equals("產品外觀")) {
return TYPE_2;
} else {
return TYPE_2;
}
} catch (Exception e) {
Log.e("例外", e.toString());
return TYPE_1;
}
}
@Override
public int getGroupTypeCount() {
return 2;
}
uj5u.com熱心網友回復：
這是陣列下標越界，你的陣列只有三個，那么最大的下標為2，你出現了3uj5u.com熱心網友回復：
小白重寫錯方法了，導致回傳的getGroudTypeCount為2應呼叫getChildTypeCountuj5u.com熱心網友回復：
我搞錯了，陣列并沒有越界。。。重新方法錯了，我給你子項增加的布局，結果重寫這個getGroudTypeCount了，導致越界轉載請註明出處，本文鏈接：https://www.uj5u.com/yidong/283465.html
