TextView animation - fade in, wait, fade out

Question

I am making a picture gallery app. I current have a imageview with a text view at the bottom. Currently it is just semitransparent. I want to make it fade in, wait 3 second, then fade out 90%. Bringing focus to it or loading a new pic will make it repeat the cycle. I have read thru a dozen pages and have tried a few things, no success. All I get is a fade in and instant fade out

Answer 1

protected AlphaAnimation fadeIn = new AlphaAnimation(0.0f , 1.0f ) ;  protected AlphaAnimation fadeOut = new AlphaAnimation( 1.0f , 0.0f ) ;  txtView.startAnimation(fadeIn); txtView.startAnimation(fadeOut); fadeIn.setDuration(1200); fadeIn.setFillAfter(true); fadeOut.setDuration(1200); fadeOut.setFillAfter(true); fadeOut.setStartOffset(4200+fadeIn.getStartOffset()); 

Works perfectly for white backgrounds. Otherwise, you need to switch values when you instantiate AlphaAnimation class. Like this:

AlphaAnimation fadeIn = new AlphaAnimation( 1.0f , 0.0f );  AlphaAnimation fadeOut = new AlphaAnimation(0.0f , 1.0f );  

This works with black background and white text color.

Kotlin Extension functions for Guy Cothal's answer:

inline fun View.fadeIn(durationMillis: Long = 250) {     this.startAnimation(AlphaAnimation(0F, 1F).apply {         duration = durationMillis         fillAfter = true     }) }  inline fun View.fadeOut(durationMillis: Long = 250) {     this.startAnimation(AlphaAnimation(1F, 0F).apply {         duration = durationMillis         fillAfter = true     }) }
