Question

按Back时出现错误“ java.lang.IndexOutOfBoundsException: setSpan (5 ... 5) ends beyond length 0”，我不明白在哪里出现此错误。当我通过“设备后退”按钮并进入片段页面（FragmentPageA）时，会发生此错误。如果我通过点击菜单进入同一页面（FragmentPageA），我不会得到相同的错误。

这是“活动”页面上的我的后按代码，

@Override
public void onBackPressed() {
    if (drawerLayout.isDrawerOpen(menuLayout))
        drawerLayout.closeDrawer(menuLayout);
    else {
        if (getFragmentManager() != null && getFragmentManager().getBackStackEntryCount() != 0) {
            getFragmentManager().popBackStack();
        } else
            showExitConfirmationDialog();
    }
}

好像其他人遇到了同样的问题here

NumberPicker.setSaveFromParentEnabled(false);       
NumberPicker.setSaveEnabled(false);
