我想动态生成Spinners。我想要生成的最大旋转器数量是7.但我想根据我从json响应得到的数据集生成Spinners。
目前，我在下面显示了代码，用于确定要生成多少个微调器。根据以下代码MealDealCatCode包含L1，L2。所以我希望将值设为2并且仅显示7个中的2个Spinners（隐藏剩余的5个Spinners）。
如何才能完成我的任务。任何帮助将不胜感激。

答案 0 :(得分：1)
我能够通过以下答案实现我想要的目标，
for (int a = 0; a < uniqueItemIdCount; a++) {
if (uniqueItemIdCount == 1) {
item1SP.setVisibility(View.VISIBLE);
}
if (uniqueItemIdCount == 2) {
item1SP.setVisibility(View.VISIBLE);
item2SP.setVisibility(View.VISIBLE);
}
if (uniqueItemIdCount == 3) {
item1SP.setVisibility(View.VISIBLE);
item2SP.setVisibility(View.VISIBLE);
item3SP.setVisibility(View.VISIBLE);
}
if (uniqueItemIdCount == 4) {
item1SP.setVisibility(View.VISIBLE);
item2SP.setVisibility(View.VISIBLE);
item3SP.setVisibility(View.VISIBLE);
item4SP.setVisibility(View.VISIBLE);
}
if (uniqueItemIdCount == 5) {
item1SP.setVisibility(View.VISIBLE);
item2SP.setVisibility(View.VISIBLE);
item3SP.setVisibility(View.VISIBLE);
