I have designed a simple layout.I have finished the design without animation, but now I want to add animations when textview click event and I don't know how to use it. Did my xml design looks good or not? Any suggestions would be appreciated.

Find the below code to make visible the view in Circuler reveal, if you send true, it'll get Invisible/Gone. If you send false, it'll get visible. anyView is the view you're going to visible/hide, it could be any view (Layouts, Buttons etc)
private fun toggle(flag: Boolean, anyView: View) {
if (flag) {
val cx = anyView.width / 2
val cy = anyView.height / 2
val initialRadius = Math.hypot(cx.toDouble(), cy.toDouble()).toFloat()
val anim = ViewAnimationUtils.createCircularReveal(anyView, cx, cy, initialRadius, 0f)
anim.addListener(object : AnimatorListenerAdapter() {
override fun onAnimationEnd(animation: Animator) {
super.onAnimationEnd(animation)
anyView.visibility = View.INVISIBLE
}
})
anim.start()
} else {
val cx = anyView.width / 2
val cy = anyView.height / 2
val finalRadius = Math.hypot(cx.toDouble(), cy.toDouble()).toFloat()
val anim = ViewAnimationUtils.createCircularReveal(anyView, cx, cy, 0f, finalRadius)
anyView.visibility = View.VISIBLE
anim.start()
}
}
Please check this link. Which will allow animations like L2R, R2L, T2B, B2T animations.
This code shows animation from left to right
TranslateAnimation animate = new TranslateAnimation(0,view.getWidth(),0,0);
animate.setDuration(500);
animate.setFillAfter(true);
view.startAnimation(animate);
view.setVisibility(View.GONE);
if you want to do it from R2L then use
TranslateAnimation animate = new TranslateAnimation(0,-view.getWidth(),0,0);
for top to bottom as
TranslateAnimation animate = new TranslateAnimation(0,0,0,view.getHeight());
and vice a versa..
Try adding this line to the xml parent layout
android:animateLayoutChanges="true"
Your layout will look like this
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:animateLayoutChanges="true"
android:longClickable="false"
android:orientation="vertical"
android:weightSum="16">
.......other code here
</LinearLayout>
I was able to show/hide a menu this way:
MenuView.java (extends FrameLayout)
private final int ANIMATION_DURATION = 500;
public void showMenu()
{
setVisibility(View.VISIBLE);
animate()
.alpha(1f)
.setDuration(ANIMATION_DURATION)
.setListener(null);
}
private void hideMenu()
{
animate()
.alpha(0f)
.setDuration(ANIMATION_DURATION)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
setVisibility(View.GONE);
}
});
}
Based on the answer of @Xaver Kapeller I figured out a way to create scroll animation when new views appear on the screen (and also animation to hide them).
It goes from this state:
to
and viceversa.
So, when the user clicks on the first button, the elements "Button 1", "Button 2", "Button 3" and "Button 4" will appear using fade animation and the element "Last Button" will move down till end. The height of the layout will change as well, allowing using scroll view properly.
This is the code to show elements with animation:
private void showElements() {
// Precondition
if (areElementsVisible()) {
Log.w(TAG, "The view is already visible. Nothing to do here");
return;
}
// Animate the hidden linear layout as visible and set
// the alpha as 0.0. Otherwise the animation won't be shown
mHiddenLinearLayout.setVisibility(View.VISIBLE);
mHiddenLinearLayout.setAlpha(0.0f);
mHiddenLinearLayout
.animate()
.setDuration(ANIMATION_TRANSITION_TIME)
.alpha(1.0f)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
updateShowElementsButton();
mHiddenLinearLayout.animate().setListener(null);
}
})
;
mLastButton
.animate()
.setDuration(ANIMATION_TRANSITION_TIME)
.translationY(mHiddenLinearLayoutHeight);
// Update the high of all the elements relativeLayout
LayoutParams layoutParams = mAllElementsRelativeLayout.getLayoutParams();
// TODO: Add vertical margins
layoutParams.height = mLastButton.getHeight() + mHiddenLinearLayoutHeight;
}
and this is the code to hide elements of the animation:
private void hideElements() {
// Precondition
if (!areElementsVisible()) {
Log.w(TAG, "The view is already non-visible. Nothing to do here");
return;
}
// Animate the hidden linear layout as visible and set
mHiddenLinearLayout
.animate()
.setDuration(ANIMATION_TRANSITION_TIME)
.alpha(0.0f)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
Log.v(TAG, "Animation ended. Set the view as gone");
super.onAnimationEnd(animation);
mHiddenLinearLayout.setVisibility(View.GONE);
// Hack: Remove the listener. So it won't be executed when
// any other animation on this view is executed
mHiddenLinearLayout.animate().setListener(null);
updateShowElementsButton();
}
})
;
mLastButton
.animate()
.setDuration(ANIMATION_TRANSITION_TIME)
.translationY(0);
// Update the high of all the elements relativeLayout
LayoutParams layoutParams = mAllElementsRelativeLayout.getLayoutParams();
// TODO: Add vertical margins
layoutParams.height = mLastButton.getHeight();
}
Note there is a simple hack on the method to hide the animation. On the animation listener mHiddenLinearLayout, I had to remove the listener itself by using:
mHiddenLinearLayout.animate().setListener(null);
This is because once an animation listener is attached to an view, the next time when any animation is executed in this view, the listener will be executed as well. This might be a bug in the animation listener.
The source code of the project is on GitHub: https://github.com/jiahaoliuliu/ViewsAnimated
Happy coding!
Update: For any listener attached to the views, it should be removed after the animation ends. This is done by using
view.animate().setListener(null);
The easiest way to animate Visibility
changes is use Transition API
which available in support (androidx) package. Just call TransitionManager.beginDelayedTransition
method then change visibility of the view. There are several default transitions like Fade
, Slide
.
import androidx.transition.TransitionManager;
import androidx.transition.Transition;
import androidx.transition.Fade;
private void toggle() {
Transition transition = new Fade();
transition.setDuration(600);
transition.addTarget(R.id.image);
TransitionManager.beginDelayedTransition(parent, transition);
image.setVisibility(show ? View.VISIBLE : View.GONE);
}
Where parent
is parent ViewGroup
of animated view. Result:
Here is result with Slide
transition:
import androidx.transition.Slide;
Transition transition = new Slide(Gravity.BOTTOM);
It is easy to write custom transition if you need something different. Here is example with CircularRevealTransition
which I wrote in another answer. It shows and hide view with CircularReveal animation.
Transition transition = new CircularRevealTransition();
android:animateLayoutChanges="true"
option does same thing, it just uses AutoTransition as transition.
Base on @ashakirov answer, here is my extension to show/hide view with fade animation
fun View.fadeVisibility(visibility: Int, duration: Long = 400) {
val transition: Transition = Fade()
transition.duration = duration
transition.addTarget(this)
TransitionManager.beginDelayedTransition(this.parent as ViewGroup, transition)
this.visibility = visibility
}
Example using
view.fadeVisibility(View.VISIBLE)
view.fadeVisibility(View.GONE, 2000)
