下図のように、インターフェース上のどの要素が選択されているかを収集する必要があります。また、選択された項目の完全な情報を返す必要があります。選択されていない場合は空を返す必要がありますが、タイトル: 処理速度などの行の他の情報を返す必要があります。
従来の方法は 2 つあり、
まず、クリックして選択し、現在の項目 isSelected を true としてマークします。「送信」をクリックすると、すべての要素が走査され、isSelected が true であるデータが検索されます。
第 2 に、要素が選択されるたびに、選択結果が自動的に更新され、選択アクションが発生したときに現在の結果が計算されます。外部アクセス (データの送信など) は、最終結果に直接アクセスするだけで済みます。
キーコード：
//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()
