Animate ImageView from alpha 0 to 1

Question

I have an imageView that I want to start as invisible. After a certain button is clicked, I want to animate the Image into view and then I want it to remain at alpha 1. How do I

Answer 1

In MainActivity.java add

public void blink(View view) {
        ImageView image = (ImageView) findViewById(R.id.imageView);
        Animation animation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.blink);
        image.startAnimation(animation1);
    }

Create file named blink.xml in res>anim folder and add this code

And make sure that onClick function on button is named blink
