NumberFormatException in setTag(int key, Object tag) method

Question

I'm trying to set a tag to an ImageView. But I got this exception:

NumberFormatException:Invalid int: "TAGTEST"

this is my code:

public static final String FIRST_TAG = "TAGTEST";
imageView.setTag(Integer.parseInt(FIRST_TAG.toString()), myIndex);

Why this code doesn't work???

Integer.parseInt(FIRST_TAG.toString())

Key has to be an Android ID.

You can use a R.id.somethingfromyourviews

Or

Create an ID in an xml file, usually called ids.xml located at res\values

 <resources>
    <item type="id" value="integer" name="your_id_name"/>
 </resources>

So you use it in code R.id.your_id_name
