How to add fading TextView animation in Android

In Android, you can use animations to achieve a fading effect on a TextView. The most common way to create a fade-in or fade-out animation is by using XML animation resources. Here's how you can add a fading animation to a TextView:

  1. Create the Animation Resources:

    Fade In Animation (res/anim/fade_in.xml):

    <?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:fromAlpha="0.0"
    android:toAlpha="1.0"
    android:duration="1000" />

    Fade Out Animation (res/anim/fade_out.xml):

    <?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/decelerate_interpolator"
    android:fromAlpha="1.0"
    android:toAlpha="0.0"
    android:duration="1000" />

  2. Apply the Animation in Your Activity or Fragment:

    TextView myTextView = findViewById(R.id.my_text_view);

// For Fade In
Animation fadeIn = AnimationUtils.loadAnimation(this, R.anim.fade_in);
myTextView.startAnimation(fadeIn);

// For Fade Out
Animation fadeOut = AnimationUtils.loadAnimation(this, R.anim.fade_out);
myTextView.startAnimation(fadeOut);

  3. Optionally, Add Animation Listeners:

    If you want to execute some code after the animation completes or at other stages of the animation, you can add an AnimationListener:

    fadeIn.setAnimationListener(new Animation.AnimationListener() {
    @Override
    public void onAnimationStart(Animation animation) {
        // Animation started
    }

    @Override
    public void onAnimationEnd(Animation animation) {
        // Animation ended
    }

    @Override
    public void onAnimationRepeat(Animation animation) {
        // Animation repeated
    }
});

That's it! You've now added a fading animation to your TextView. You can adjust the duration attribute in the XML files to make the animation faster or slower.

  1. Implementing fade-in and fade-out animation for TextView:

    • Description: Apply fade-in and fade-out animations to a TextView for smooth visibility transitions.
    • Code:
      val textView = findViewById<TextView>(R.id.textView)

// Fade In Animation
val fadeIn = ObjectAnimator.ofFloat(textView, "alpha", 0f, 1f)
fadeIn.duration = 1000

// Fade Out Animation
val fadeOut = ObjectAnimator.ofFloat(textView, "alpha", 1f, 0f)
fadeOut.duration = 1000

// Play animations
val animatorSet = AnimatorSet()
animatorSet.playSequentially(fadeIn, fadeOut)
animatorSet.start()

  2. Using XML animation resources for fading TextView in Android:

    • Description: Define fade-in and fade-out animations in XML resources for cleaner and reusable code.

    • Code:

      <!-- res/animator/fade_in.xml -->
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <objectAnimator
        android:propertyName="alpha"
        android:valueFrom="0"
        android:valueTo="1"
        android:duration="1000" />
</set>

<!-- res/animator/fade_out.xml -->
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <objectAnimator
        android:propertyName="alpha"
        android:valueFrom="1"
        android:valueTo="0"
        android:duration="1000" />
</set>

      // Load animations from XML
val fadeIn = AnimatorInflater.loadAnimator(this, R.animator.fade_in) as Animator
val fadeOut = AnimatorInflater.loadAnimator(this, R.animator.fade_out) as Animator

// Play animations
val animatorSet = AnimatorSet()
animatorSet.playSequentially(fadeIn, fadeOut)
animatorSet.start()

  3. Customizing duration and interpolators for fade animation:

    • Description: Adjust the duration and interpolators to control the speed and style of the fade animation.
    • Code:
      <!-- Customize duration and interpolator in XML -->
<!-- res/animator/fade_in.xml -->
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <objectAnimator
        android:propertyName="alpha"
        android:valueFrom="0"
        android:valueTo="1"
        android:duration="500"
        android:interpolator="@android:anim/accelerate_interpolator" />
</set>

  4. Handling multiple TextViews with fading animation:

    • Description: Apply fade animations to multiple TextViews simultaneously or sequentially.
    • Code:
      val textView1 = findViewById<TextView>(R.id.textView1)
val textView2 = findViewById<TextView>(R.id.textView2)

// Fade In Animation
val fadeIn = ObjectAnimator.ofFloat(textView1, "alpha", 0f, 1f)
fadeIn.duration = 1000

// Fade Out Animation
val fadeOut = ObjectAnimator.ofFloat(textView2, "alpha", 1f, 0f)
fadeOut.duration = 1000

// Play animations
val animatorSet = AnimatorSet()
animatorSet.playTogether(fadeIn, fadeOut)
animatorSet.start()

  5. Adding delay to fade-in or fade-out in Android TextView:

    • Description: Introduce a delay before starting the fade-in or fade-out animation.
    • Code:
      val textView = findViewById<TextView>(R.id.textView)

// Fade In Animation with delay
val fadeIn = ObjectAnimator.ofFloat(textView, "alpha", 0f, 1f)
fadeIn.duration = 1000
fadeIn.startDelay = 500

// Play animation
fadeIn.start()

  6. Sequential fading animation for multiple TextViews:

    • Description: Sequence fade-in and fade-out animations for multiple TextViews.
    • Code:
      val textView1 = findViewById<TextView>(R.id.textView1)
val textView2 = findViewById<TextView>(R.id.textView2)

// Fade In Animation
val fadeIn1 = ObjectAnimator.ofFloat(textView1, "alpha", 0f, 1f)
fadeIn1.duration = 1000

// Fade Out Animation
val fadeOut1 = ObjectAnimator.ofFloat(textView1, "alpha", 1f, 0f)
fadeOut1.duration = 1000

// Fade In Animation
val fadeIn2 = ObjectAnimator.ofFloat(textView2, "alpha", 0f, 1f)
fadeIn2.duration = 1000

// Fade Out Animation
val fadeOut2 = ObjectAnimator.ofFloat(textView2, "alpha", 1f, 0f)
fadeOut2.duration = 1000

// Play animations sequentially
val animatorSet = AnimatorSet()
animatorSet.playSequentially(fadeIn1, fadeOut1, fadeIn2, fadeOut2)
animatorSet.start()

  7. Animating text changes with a fading effect in Android:

    • Description: Animate text changes in a TextView with a fade-in and fade-out effect.
    • Code:
      val textView = findViewById<TextView>(R.id.textView)

// Fade Out Animation
val fadeOut = ObjectAnimator.ofFloat(textView, "alpha", 1f, 0f)
fadeOut.duration = 500

// Set new text and start fade-in animation
fadeOut.addListener(object : AnimatorListenerAdapter() {
    override fun onAnimationEnd(animation: Animator?) {
        textView.text = "New Text"
        val fadeIn = ObjectAnimator.ofFloat(textView, "alpha", 0f, 1f)
        fadeIn.duration = 500
        fadeIn.start()
    }
})

// Start fade-out animation
fadeOut.start()

  8. Creating reusable fade animation functions for TextView:

    • Description: Encapsulate fade animation logic into reusable functions for cleaner and modular code.
    • Code:
      fun createFadeInAnimation(view: View, duration: Long, startDelay: Long = 0): ObjectAnimator {
    val fadeIn = ObjectAnimator.ofFloat(view, "alpha", 0f, 1f)
    fadeIn.duration = duration
    fadeIn.startDelay = startDelay
    return fadeIn
}

fun createFadeOutAnimation(view: View, duration: Long, startDelay: Long = 0): ObjectAnimator {
    val fadeOut = ObjectAnimator.ofFloat(view, "alpha", 1f, 0f)
    fadeOut.duration = duration
    fadeOut.startDelay = startDelay
    return fadeOut
}

// Usage
val fadeIn = createFadeInAnimation(textView, 1000, 500)
val fadeOut = createFadeOutAnimation(textView, 1000)
