As shown in the figure below, it is necessary to collect which elements on the interface are selected. And it needs to return the complete information of the selected Item, if it is not selected, it needs to return empty, but other information of the row needs to be returned, such as title: Processing speed, etc.
There are two conventional methods.
First, click to select and mark the current Item isSelected as true. When submit is clicked, all elements are traversed to find the data whose isSelected is true.
Second, every time an element is selected, the selection result is automatically updated, and the current result is calculated when the selection action occurs. External access (such as submitting data) only needs to directly access the final result.
key code:
//ListView getView部分代码
// 结构化View初始化
if (viewHolder.scv_labels != null && itemData != null) {
boolean hasReviewLabelDTOList = itemData.reviewLabelDTOList != null && itemData.reviewLabelDTOList.size() > 0;
if (hasReviewLabelDTOList) {
// 设置数据
viewHolder.scv_labels.setData(itemData);
}
if (itemData.proDescEval > NO_STAR && hasReviewLabelDTOList) {
// 显示隐藏
viewHolder.scv_labels.setVisibility(View.VISIBLE);
} else {
viewHolder.scv_labels.setVisibility(View.GONE);
}
}
//点击Item，自动计算当前选择结果
inner class LabelItemClickImpl: ILabelItemClickListener {
override fun onItemClick() {
curViewData?.selectedLabelData = getStructuredLabelData()
}
}
fun getStructuredLabelData(): Any {
if (curViewData == null || curViewData?.reviewLabelDTOList == null || curViewData?.reviewLabelDTOList?.size == 0) {
return ""
}
curViewData?.reviewLabelDTOList?.let {
val selectedLabelData : ArrayList<StructuredLabelItem> = ArrayList()
for (i in it.indices) {
val itemData = adapterList[i]?.getSelectedItem()
selectedLabelData.add(StructuredLabelItem(it[i].labelId, it[i].labelName, itemData))
}
return JSONObject.toJSON(selectedLabelData)

return ""

if (currentSelectedIndex >= 0 && currentSelectedIndex < data.size) {
