If Random Equals a Number, do this

It's me again.... >.<

I'm having troubles with an if statement to do something if the current string in a TextView is "Heads."

This is my current code:

 if (myCoin = "Heads") {

                 ImageView img = (ImageView) findViewById(R.id.imageView);
                 img.setImageResource(R.mipmap.heads);

             }

"myCoin" is the name of a string that contains the words "Heads" and "Tails."

final String[] myCoin= {"Heads", "Tails"};

When a random number is generated, the TextView displays one of those words depending on the number. However, I am not able to run the code due to the squiggly red-line under (myCoin = "Heads") that reads:

Incompatible Types.

Required: Java.Lang.String[]

Found: Java.Lang.String

As you can see, my string DOES have the square brackets, so I'm wondering if I can even use myCoin in an if statement.
