Is it possible to make a checkbox/radio button uncheckable?
提问by JuiCe
The program I am making has several views in which the user is trying to basically figure out a lot of boolean values. Sounds strange, but what I mean is that my device will connect to another device via bluetooth, and then read the status of that device. I basically display a checklist of the current status of that device. So depending on what that device is doing, different checkboxes are checked. Is there a way to make all of the checkboxes unselectable?
我正在制作的程序有几个视图,用户试图在这些视图中基本上找出很多布尔值。听起来很奇怪,但我的意思是我的设备将通过蓝牙连接到另一个设备,然后读取该设备的状态。我基本上显示了该设备当前状态的清单。因此,根据该设备正在执行的操作,会选中不同的复选框。有没有办法使所有复选框都不可选择?
Even better, is there a way to hardcode this into the XML file?
更好的是,有没有办法将其硬编码到 XML 文件中?

Have you considered using android:clickable
for an xml attribute for your checkboxes?
您是否考虑过android:clickable
为复选框使用xml 属性?
From the documentation:
从文档:
Defines whether this view reacts to click events.
定义此视图是否对单击事件作出反应。
If it cannot react to click events, then it effectively becomes uncheckable.
如果它不能对点击事件做出反应,那么它实际上变得不可检查。

<CheckBox
android:id="@+id/blahblah"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:enabled="false" />
and in your code you can call cbox.setChecked(boolean)
在你的代码中你可以调用 cbox.setChecked(boolean)

Check this out: http://developer.android.com/reference/android/widget/CheckBox.html
看看这个:http: //developer.android.com/reference/android/widget/CheckBox.html
You can use checkbox.setEnabled(false)
to make it unselectable.
您可以使用checkbox.setEnabled(false)
使其无法选择。
Try this in your XML: android:enabled="false"
在你的 XML 中试试这个: android:enabled="false"
It's supposedly deprecated, but may work depending on your traget SDK.
它应该已被弃用,但可能会根据您的 traget SDK 工作。
Hope that helps!
希望有帮助!

to expand on what crocboy and nicholas.hauschild said.
扩展 crocboy 和 nicholas.hauschild 所说的内容。
Setting this in you XML
在你的 XML 中设置这个
android:enabled="false"
will make the button/checkbox be grayed-out, to show it is disabled
将使按钮/复选框变灰,以显示它已被禁用
Another way to do this is to set it to:
另一种方法是将其设置为:
android:clickable="false"
Here is the code to make a RadioButton that is red, that turns green when checked (in your code), but can not be checked by the user.
这是使 RadioButton 为红色的代码,选中时(在您的代码中)变为绿色,但用户无法检查。
android:checked="false"
android:textColor="#d1d2d4"
android:buttonTint="#d1202d"
android:textColorHighlight="#248d51"
android:clickable="false"
AND here is the code to check it (this is using JSON: so it is checking if english=="yes")
这是检查它的代码(这是使用 JSON:所以它正在检查 english=="yes")
String yes = "yes";
if(yourObject.english.equals(yes)) {
if (m_english.isChecked()) {/*do nothing */}
else m_english.toggle();
}
