在发布到Firestore时对radioButton使用相同的值 [英] using same value for radioButton when posting to firestore

问题描述

我的布局中有2个 radioButtons .当询问是否有保险时，一种用于是，另一种用于 no .当我单击我的 save 按钮并将数据发布到 firestore 时，它同时显示 NO INSURED 和 YES INSURED .我设置代码的方式就是为什么这样设置，但是我想做的是提供一个来源，如果该人单击 yes 或 no 然后在中单击firestore 我将有 Insured:是或 Insured:否.我将代码发布到

I have a 2 radioButtons in my layout. One is for yes and the other is for no when asked if insured or not. When I click my save button and the data posts to firestore, it shows both NO INSURED and YES INSURED. The way I have my code set up is why it's that way but what I want to do is have one source where if the person clicks yes or no then in firestore I will have Insured : Yes or Insured : No. I will post my code down below

推荐答案

第一件事，

当我单击我的 save 按钮并将数据发布到 firestore

根据您的代码，这没有发生.您应该使用 OnClickListener 方法来实现您的想法.我建议仔细阅读文档.

This is not happening according to your code. You should use OnClickListener method to implement your thought. I suggest going through this documentation.

希望，您正在为 RadioButton 使用 RadioGroup .这将不允许一次选择多个 RadioButton .此处是实现 RadioGroup 的方法

Hope, you are using RadioGroup for your RadioButton. That won't allow more than one RadioButton to be selected at a single time. Here is how you can implement RadioGroup.

使用单个键存储布尔值，而不是在 Firestore 中为 RadioButton 状态存储多个键值对.试试这个:

Use a single key to store a boolean value instead of storing multiple key-value pairs for RadioButton state in Firestore. Try this :

if (radioGroup.getCheckedRadioButtonId() == R.id.yesRadioButton){
    myMap.put("isInsured", true);
} else {
    myMap.put("isInsured", false);
}

代替此:

myMap.put(KEY_YES_INSURED, yes_button);
myMap.put(KEY_NO_INSURED, no_button);

如果正确执行了所有上述步骤，则数据库应为 RadioButton 状态存储一个值.尝试让我们知道是否可行.

If you do all the mentioned steps correctly your database should store one value for your RadioButton states. Try and let us know if this worked or not.
