Como se muestra en la figura a continuación, es necesario recopilar qué elementos de la interfaz se seleccionan. Y necesita devolver la información completa del artículo seleccionado, si no está seleccionado, debe devolver vacío, pero debe devolver otra información de la fila, como título: velocidad de procesamiento, etc.
Existen dos métodos convencionales:
primero, haga clic para seleccionar y marcar el elemento actual isSelected como verdadero. Cuando se hace clic en enviar, se recorren todos los elementos para encontrar los datos cuyo isSelected es verdadero.
En segundo lugar, cada vez que se selecciona un elemento, el resultado de la selección se actualiza automáticamente y el resultado actual se calcula cuando se produce la acción de selección. El acceso externo (como el envío de datos) solo necesita acceder directamente al resultado final.
clave:
//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))
