Android ListView - Unclickable Checkbox
我希望以前有人见过这个问题。我有一个列表视图，其中所有元素都有一个复选框。除了有一个不可选择的复选框（无法检查和取消选中）之外，这一切都运行良好。它不是列表中的第一项，并且所有设备上都没有问题。适用于三星S3，但在Nexus 6P上有问题。
经过一番调查后，我打开了“显示布局界限”。在开发人员选项中。这是我看到一些非常有趣的东西，无法点击的元素没有画出任何界限。在下面的示例中，＆＃39; Bar Tunes＆＃39;是不可选择的。
有没有人知道为什么会这样。这是布局文件。

这些是相关功能。列表视图是一个ExpandableListView，如果有帮助的话。
此问题似乎只发生在Android 7.0及更高版本上。我也在Android 8上证实了这一点。
2 个答案:
答案 0 :(得分：0)
因为您有一些物品没有使用convertView给您的ListView。下次您获得该视图并使用它时，它将是这样。
当您使用其他视图工具时，建议使用getViewTypeCount()和getItemViewType()。
答案 1 :(得分：0)
所以我找到了解决此问题的方法。单元格的位置设置为0,0。 我已经重写了ListView的dispatchTouchEvent，部分代码如下。
case ACTION_UP:
// HACK: This is a fix for Android setting some views position to 0,0
if (mPassOnTouch)
{
View view = getChild(aMotionEvent);
if (view != null && isBadView(view))
{
int[] location = new int[2];
getLocationInWindow(location);
List<View> views = findClickableViews(view, new Vector<View>());
for (View subView: views)
{
int[] position = calculatePosition(subView, view, location);
if (isWithIn(subView, position, (int)aMotionEvent.getRawX(), (int)aMotionEvent.getRawY()))
{
subView.performClick();
break;
}
}
}
}
break;
代码检查运动事件位置下的视图。 （获取视图位置所需的所有数据均可用，但是函数getLocationInWindow或getLocationOnScreen错误）。然后，我检查视图位置是否为0,0。然后找到所有可单击的子视图，并手动调整其位置。
需要执行点击，因为onTouchEvent需要一个“正确”的位置。
