ListView控件getCheckedItemPositions通话问题 [英] ListView getCheckedItemPositions call issue

问题描述

我有与getCheckedItemPositions呼吁ListView的问题。第一次调用工作，但后续调用返回相同的结果，即使previous检查项目是听之任之。

I am having issues with the getCheckedItemPositions call for ListView. The first call works but subsequent calls returned the same results even if the previous checked items were unchecked.

如：

第一次调用：位置0安培; 1检查，结果表明0安培; 1检查
第二个呼叫：位置0安培; 1未被选中，结果仍显示0安培; 1被检查。

first call: positions 0 & 1 are checked, result shows 0 & 1 are checked 2nd call: position 0 & 1 are unchecked, result still shows 0 & 1 are checked.

这是一个错误或getCheckedItemPositions不起作用这种方式？有人可以澄清吗？谢谢！

Is this a bug or getCheckedItemPositions doesn't work this way? Can someone clarify please? Thanks!

推荐答案

使用valueAt（）而不是get（）方法，然后使用keyAt（）来找到合适的索引到检查itmes为我工作。

Use valueAt() instead of get(), then use keyAt() to find the right index to the checked itmes works for me.

SparseBooleanArray checkedItems = lview.getCheckedItemPositions();
if (checkedItems.size() > 0) {
 for (int i=0; i<checkedItems.size(); i++) {
  if (checkedItems.valueAt(i)) {
    Log.d("checked item: " + lview.getItemAtPosition(checkedItems.keyAt(i)));
  }
 }
}
