我是Android应用程序的新手。我创建了一个关于医疗目的的应用程序。早期它工作正常。但是当我添加一些验证时，数据没有插入数据库中。无法找到任何错误。当我正在尝试调试代码，它正在之后逃避验证码！BloodGlucose.equals（“”）。无法找到解决方案 请帮忙......

但是当我尝试使用以下验证时，数据没有插入到表中。我没有在logcat中收到任何错误。
else if (!BloodGlucose.equals("")) {
int_glucose = Integer.parseInt(BloodGlucose);
if (!(int_glucose >= 80 && int_glucose <= 160)) {
invalid = true;
System.out.println("in address2");
Toast.makeText(getApplicationContext(), "Please valid reading", Toast.LENGTH_SHORT) .show();
}
/*invalid = true;
Toast.makeText(getApplicationContext(),
"Please valid reading", Toast.LENGTH_SHORT)
.show();*/
}
答案 0 :(得分：0)
有趣！
您创建了 if-else链。您必须在条件之前制定单独的条件，如同（无效== false），即删除其他。它会起作用。
