How to set integer tag to a widget in xml layout file?

Question

I have simple layout, but I can only set string tag. How to set integer tag?

<ImageView   android:layout_width="wrap_content"   android:layout_height="wrap_content"   android:tag="1"   android:src="@drawable/image" /> 

---

UPDATE

I found out how to set Integer tags in xml layout. We need to specify an integer variable in any xml resource file. That should look like that:

res/values/value.xml:

<?xml version="1.0" encoding="UTF-8"?> <resources> <integer name="int1">15</integer> <integer name="int2">1</integer> </resources> 

And now we are free to use "@integer/int1" or "@integer/int2" as tags for our xml widgets, for example:

<ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:tag="@integer/int2" android:src="@drawable/image" /> 

However, in my case I preferred to set tag programmatically :)

Answer 1

In xml you can only set String. But in code you can use View.setTag(int value); because it takes Object. To read a value you need to cast it to Integer int value = (Integer)view.getTag();

Answer 2

From the author's edit I attempted to use @integer/int2 to set the tag as an integer, but it still seems that getTag() is returning the tag as a String (at least in Jellybean). Integer.parseInt(String) can convert a String to an Integer and @integer/int2 can validate that your tag is a proper Integer. So if you want to put an Integer in a tag through XML that is probably the best route. Downside, since it uses parseInt it likely takes a little more time than having it stored as a int the whole time.
