Comparing a view's tag to an integer

Question

I'm trying to compare an array of integers to the tags of imageviews I have uniquely made.

using this line:

if(grid[i][j] == buttons[k].getTag()){

I know im on the right tracks, but I can't figure out if i need to cast it or use a method. I know its a simple question, but any help would be greatly appreciated, thanks.

Solution 1

I think your Tag is rather a String than an Integer.

If that's the case convert your Integer toString() and check if it equals().

Solution 2

Tag is an Object, so put an Integer:

/*
 * UseValueOf
 * ----------
 * Priority: 4 / 10
 * Severity: Warning
 * Category: Performance
 * 
 * You should not call the constructor for wrapper classes directly, such as`new
 * Integer(42)`. Instead, call the valueOf factory method, such as
 * Integer.valueOf(42). This will typically use less memory because common
 * integers such as 0 and 1 will share a single instance.
 */
//MyView.setTag(new Integer(42));
MyView.setTag(Integer.valueOf(42));

Then retrieve the value like this:

int tagValue = (Integer)MyView.getTag();

Solution 3

You have to convert buttons[k].getTag() in integer.

Do this:

if(grid[i][j] == Integer.parseInt(buttons[k].getTag().toString())){

Solution 4

You pass in an integer and get in an index variable. Here is the code snippet

int Index = Integer.parseInt(v.getTag().toString());
System.out.println(Index);
