Show and hide a View with a slide up/down animation
With the new animation API that was introduced in Android 3.0 (Honeycomb) it is very simple to create such animations.
Sliding a View down by a distance:
view.animate().translationY(distance);
You can later slide the View back to its original position like this:
view.animate().translationY(0);
You can also easily combine multiple animations. The following animation will slide a View down by its height and fade it in at the same time:
// Prepare the View for the animation
view.setVisibility(View.VISIBLE);
view.setAlpha(0.0f);
// Start the animation
view.animate()
.translationY(view.getHeight())
.alpha(1.0f)
.setListener(null);
You can then fade the View back out and slide it back to its original position. We also set an AnimatorListener so we can set the visibility of the View back to GONE once the animation is finished:
view.animate()
.translationY(0)
.alpha(0.0f)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
view.setVisibility(View.GONE);
}
});
Show/Hide View using Slide Up and Down Animation
Create below xml in anim folder
slid_down.xml :
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="1000"
android:fromYDelta="0"
android:toYDelta="100%" />
</set>
slid_up.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >>reate Amim common util class :public class MyUtils {
public void SlideUP(View view,Context context)
{
view.startAnimation(AnimationUtils.loadAnimation(context,
R.anim.slid_down));
}
public void SlideDown(View view,Context context)
{
view.startAnimation(AnimationUtils.loadAnimation(context,
R.anim.slid_up));
}
}
Android - Show/Hide Toolbar in app on user touch with slide up and slide down animation
if (toolbar.getVisibility() == View.VISIBLE) {
appbar.animate().translationY(-112).setDuration(600L)
.withEndAction(new Runnable() {
@Override
public void run() {
toolbar.setVisibility(View.GONE);
}
}).start();
} else {
toolbar.setVisibility(View.VISIBLE);
appbar.animate().translationY(0).setDuration(600L).start();
}
SwiftUI: how to make a view disappear with a slide to the top?
You could use the .transition modifier.
documentation
LoadingView()
.transition(.move(edge: .top))
But don´t forget to animate it:
.onAppear {
self.loading = true
callAPI() { elements in
self.elements = elements
DispatchQueue.main.async { // as this is probably from background Thread dispatch it
self.loading = false
}
}
}.animation(.default, value: loading)
Slidedown and slideup layout with animation
Create two animation xml under res/anim folder
slide_down.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="1000"
android:fromYDelta="0"
android:toYDelta="100%" />
</set>
slide_up.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="1000"
android:fromYDelta="100%"
android:toYDelta="0" />
</set>
Load animation Like bellow Code and start animation when you want According to your Requirement
//Load animation
Animation slide_down = AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.slide_down);
Animation slide_up = AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.slide_up);
// Start animation
linear_layout.startAnimation(slide_down);
Hiding and showing UITableview with slide down and slide up animation
Simply animating your UITableView frame if you are using non constraints approach, or making the bottom constraint IBOutlet and changing the constant value
- (void)viewDidLayoutSubViews
{
[super viewDidLayoutSubViews];
self.originalTableViewFrame = accountBalanceTableView.frame;
}
- (IBAction)mPesoAccount:(id)sender {
if (accountBalanceTableView.isHidden)
{
[UIView animateWithDuration:.3 animations:^{
accountBalanceTableView.frame = self.originalTableViewFrame;
}completion:^(BOOL finished) {
accountBalanceTableView.hidden = NO;
}];
}
else
{
[UIView animateWithDuration:0.3 animations:^{
accountBalanceTableView.frame = CGRectMake(originalTableViewFrame.origin.x, originalTableViewFrame.origin.y + originalTableViewFrame.size.height, originalTableViewFrame.size.width, 0);
} completion:^(BOOL finished) {
accountBalanceTableView.hidden = YES;
}];
}
}
Animate a view to slide up and hide on tap in SwiftUI
Removing view from hierarchy is always animated by container, so to fix your modifier it is needed to apply .animation on some helper container (note: Group is not actually a real container).
Here is corrected variant
struct BannerModifier: ViewModifier {
@Binding var model: BannerData?
func body(content: Content) -> some View {
content.overlay(
VStack { // << holder container !!
if model != nil {
VStack {
HStack(alignment: .firstTextBaseline) {
Image(systemName: "exclamationmark.triangle.fill")
VStack(alignment: .leading) {
Text(model?.title ?? "")
.font(.headline)
if let message = model?.message {
Text(message)
.font(.footnote)
}
}
}
.padding()
.frame(minWidth: 0, maxWidth: .infinity)
.foregroundColor(.white)
.background(Color.red)
.cornerRadius(10)
.shadow(radius: 10)
Spacer()
}
.padding()
.transition(AnyTransition.move(edge: .top).combined(with: .opacity))
.onTapGesture {
withAnimation {
model = nil
}
}
.gesture(
DragGesture()
.onChanged { _ in
withAnimation {
model = nil
}
}
)
}
}
.animation(.easeInOut) // << here !!
)
}
}
Tested with Xcode 12.1 / iOS 14.1 and test view:
struct TestBannerModifier: View {
@State var model: BannerData?
var body: some View {
VStack {
Button("Test") { model = BannerData(title: "Error", message: "Fix It!")}
Button("Reset") { model = nil }
}
.frame(maxWidth: .infinity, maxHeight: .infinity)
.modifier(BannerModifier(model: $model))
}
}
