Dynamically Set ID to a Button in Android
12,823
Solution 1
In your res/values folder you can keep an ids.xml file, where you can define:
<resources>
<item type="id" name="your_button_id"/>
...
</resources>
Then, you can use it in your code:
changeButton.setId(R.id.your_button_id);
Solution 2
If your goal is to track it, you could try setTag:
changeButton.setTag("any_tag");
Notice that the tag is of type Object, meaning it could be any object you want (String, int, Date, CustomeObject, ...etc).
