How create swipe to back?
In iOS:
[assembly: ExportRenderer(typeof(HIPSTO.Controls.CustomContentPage), typeof(HIPSTO.iOS.Platform.Renderers.IOSPageRenderer))]
namespace HIPSTO.iOS.Platform.Renderers
{
public class IOSPageRenderer : PageRenderer
{
public override void ViewWillAppear(bool animated)
{
base.ViewWillAppear(animated);
ViewController.NavigationController.InteractivePopGestureRecognizer.Enabled = true;
ViewController.NavigationController.InteractivePopGestureRecognizer.Delegate = new UIKit.UIGestureRecognizerDelegate();
}
}
}
But it only works from the edge. It is necessary from any place.
No ideas with android
As below shown:
First, You could achieved by NavigationPageRenderer in android.
This is GIF of this demo
TransitionNavigationPageRender.cs
[assembly: ExportRenderer(typeof(SwipePageDemo.Controls.TransitionNavigationPage), typeof(TransitionNavigationPageRenderer))]
namespace SwipePageDemo.Droid.Renderers
{
public class TransitionNavigationPageRenderer : NavigationPageRenderer
{
public TransitionNavigationPageRenderer(Context context) : base(context)
{
}
protected override void SetupPageTransition(Android.Support.V4.App.FragmentTransaction transaction, bool isPush)
{
if (isPush)
{
}
else
{
transaction.SetCustomAnimations(Resource.Animation.enter_left, Resource.Animation.exit_right,
Resource.Animation.enter_right, Resource.Animation.exit_left);
}
}
}
}
enter_left.xml
<?xml version="1.0" encoding="utf-8" ?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:propertyName="enter_from_left"
android:shareInterpolator="false">
<translate
android:fromXDelta="-100%" android:toXDelta="0%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="300"/>
</set>
enter_right.xml
<?xml version="1.0" encoding="utf-8" ?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="100%" android:toXDelta="0%"

android:duration="300" />
</set>
exit_left.xml

<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="0%" android:toXDelta="100%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="300" />
</set>

You could achieved it by threshold property of SwipeGestureRecognizer class
The SwipeGestureRecognizer class also includes a Threshold property, that can be optionally set to a uint value that represents the minimum swipe distance that must be achieved for a swipe to be recognized, in device-independent units. The default value of this property is 100, meaning that any swipes that are less than 100 device-independent units will be ignored. If you want to increase the area that can be swiped, you could reduce this data of Threshold like following code.
var leftSwipeGesture = new SwipeGestureRecognizer { Direction = SwipeDirection.Right };
leftSwipeGesture.Threshold = 50;
leftSwipeGesture.Swiped += (sender, e) => Navigation.PopAsync();
stackLayout.GestureRecognizers.Add(leftSwipeGesture);
I changed value of leftSwipeGesture.Threshold to 50, this is GIF of swipe.

I want to implement enter and exit fragment animation during navigation in MVVMCross project.
[MvxFragmentPresentation(typeof(TestViewModel),
Resource.Id.content_frame, true,
Resource.Animation.enter_from_right,
Resource.Animation.exit_nothing_animation)]
enter_from_right
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="100%p" android:toXDelta="0%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="#android:integer/config_mediumAnimTime" />
</set>
exit_nothing_animation
<?xml version="1.0" encoding="UTF-8" ?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="300"
android:fromAlpha="1"
android:toAlpha="1" />
I expect that new fragment slide from right over the old frgamnet and old fragment will remain in the same place.
But new fragment just instantly appears without animation
Other topics suggest use Add insted Replace, but what the right way in MVVMCross project?
Answer is override this method in base fragment class
public override Animation OnCreateAnimation(int transit, bool enter, int nextAnim)
{
if (nextAnim == Resource.Animation.enter_from_right)
{
ViewCompat.SetTranslationZ(view, 1f);
}
else
{
ViewCompat.SetTranslationZ(view, 0f);
}
return base.OnCreateAnimation(transit, enter, nextAnim);
}
I want to add animation to my registration page. I have 6 EditTexts and I want them to come one by one from right to left. I'm new to android, someone help me please.
Screenshot registration page
You can create your custom animation xmls and place inside anim folder inside resources folder:
left_swipe.xml
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500"
android:fromXDelta="100%"
android:toXDelta="0%" >
</translate>
right_swipe.xml
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500"
android:fromXDelta="-100%"
android:toXDelta="0%" >
</translate>
You can start animation like :
RightAnim = AnimationUtils.loadAnimation(Screen.this, R.anim.right_swipe);
ScreenAnimation.startAnimation(RightAnim );
Plz make sure your animation xml file under res>anim
This is for slide_in_left
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="-50%p" android:toXDelta="0"
android:duration="2500"/>
<alpha android:fromAlpha="0.0" android:toAlpha="1.0"
android:duration="#android:integer/config_mediumAnimTime" />
</set>
and this is for slide_in_right
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="50%p" android:toXDelta="0"
android:duration="2500"/>
<alpha android:fromAlpha="0.0" android:toAlpha="1.0"
android:duration="#android:integer/config_mediumAnimTime" />
</set>
in your java code
Animation a = AnimationUtils.loadAnimation(RegisterActivity.this, R.anim.slide_in_left);
a.reset();
etusername.clearAnimation();
etusername.startAnimation(a);
Animation b = AnimationUtils.loadAnimation(RegisterActivity.this, R.anim.slide_in_right);
b.reset();
etpassword.clearAnimation();
etpassword.startAnimation(b);
left to right animation:
leftToRight.xml
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate android:fromXDelta="-100%" android:toXDelta="0%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="700"/>
</set>
right to left animation:
rightToLeft
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="0%" android:toXDelta="100%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="700" />
</set>
write below code in your activity class
private Animation m_animationLeft;
private Animation m_animationRight;
m_animationLeft = AnimationUtils.loadAnimation(this, R.anim.leftToRight);
m_animationRight = AnimationUtils.loadAnimation(this, R.anim.rightToLeft);
editTextOne.startAnimation(m_animationLeft);
m_animationLeft.setAnimationListener(new AnimationListener()
{
#Override
public void onAnimationStart(Animation p_animation)
{
}
#Override
public void onAnimationRepeat(Animation p_animation)
{
}
#Override
public void onAnimationEnd(Animation p_animation)
{
// Start animation on another edittext . If you want to perform animation one by one edittext
}
});
}
}.start();
I'm trying to create an Android app, and switch between activities with a slide, when the previous activity slides out to the right, and the new activity comes in the left.
I can do somethibg like this, with:
Intent intent = new Intent(getContext(), NextActivity.class);
startActivity(intent);
overridePendingTransition(R.anim.in_ltr, R.anim.out_ltr);
Where the in_ltr.xml is:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="#android:anim/accelerate_decelerate_interpolator">
<translate
android:fromXDelta="-100%p"
android:toXDelta="0"
android:duration="700"
/>
</set>
And the out_ltr.xml is:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="#android:anim/accelerate_decelerate_interpolator">
<translate
android:fromXDelta="0"
android:toXDelta="100%p"
android:duration="500"
/>
</set>
It's almost perfect, but a small black gap appers between the two activity during the animation. You can see it here on YouTube.
I've tried anything I found in the Google in the last hour, but nothing seems to remove that gap. Is it possible to remove that gap?
Thanks!
Try to set Alpha with translate effect....
Try This...
slide_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:interpolator/accelerate_cubic">
<translate
android:fromXDelta="0%"
android:toXDelta="100%"
android:duration="400" />
<alpha
android:fromAlpha="1.0"
android:toAlpha="0.3"
android:duration="500" />
</set>
Add this two file in res/anim folder.
slide_in.xml
<?xml version="1.0" encoding="utf-8"?>
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="#android:integer/config_longAnimTime"
android:fromXDelta="100%p"
android:toXDelta="0%p">
</translate>
slide_out.xml
<?xml version="1.0" encoding="utf-8"?>
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="#android:integer/config_longAnimTime"
android:fromXDelta="0%p"
android:toXDelta="-100%p">
</translate>
And write the following code in onCreate() method of next activity that you pass through the Intent.
overridePendingTransition(r.anim.slide_in, R.anim.slide_out);
hope it will remove your space
Try this: create a RootActivity.java and extend it in your activity.
import android.app.Activity;
import android.os.Bundle;
public class RootActivity extends Activity {
int onStartCount = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
onStartCount = 1;
if (savedInstanceState == null) // 1st time
{
this.overridePendingTransition(R.anim.anim_slide_in_left,
R.anim.anim_slide_out_left);
} else // already created so reverse animation
{
onStartCount = 2;
}
}
#Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
if (onStartCount > 1) {
this.overridePendingTransition(R.anim.anim_slide_in_right,
R.anim.anim_slide_out_right);
} else if (onStartCount == 1) {
onStartCount++;
}
}
}
add these animations to anim folder:
anim_slide_in_left.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="600"
android:fromXDelta="100%"
android:toXDelta="0%" >
</translate>
</set>
anim_slide_in_right.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="600"
android:fromXDelta="-100%"
android:toXDelta="0%" >
</translate>
</set>
anim_slide_out_right.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="600"
android:fromXDelta="0%"
android:toXDelta="100%" >
</translate>
</set>
anim_slide_out_left.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="600"
android:fromXDelta="0%"
android:toXDelta="-100%" >
</translate>
</set>
Try to add below item into your AppTheme
<item name="android:windowIsTranslucent">true</item>
Sorry guys, I was very, very stupid.
I changed the duration to the same amount of time, and the gap disappeared.
I want to slide from left to right (opposite right to left in this code below). My current task is running correctly on button click.
Here is the source:
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btnopen = (Button)findViewById(R.id.btnWindowAnimation);
btnopen.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(MainActivity.this, SecondActivity.class);
Bundle bundle =ActivityOptions.makeCustomAnimation(getApplicationContext(), ` `R.anim.animation,R.anim.animation2).toBundle();
startActivity(i, bundle);
}
});
}
Here Animation 1:
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="100%p"
android:toXDelta="0"
android:duration="500"/>
Here Animation 2:
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="0"
android:toXDelta="-50%p"
android:duration="500"/>
This is for left to right animation:
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate android:fromXDelta="-100%" android:toXDelta="0%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="700"/>
</set>
This is for right to left animation:
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="0%" android:toXDelta="100%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="700" />
</set>
Check this link.
Here is the first answer:
<translate
android:fromXDelta="-100%"
android:toXDelta="0%"
android:duration="500"/>
</set>
And here is the second XML:
<translate
android:fromXDelta="0%"
android:toXDelta="100%"
android:duration="500" />
</set>
I am trying to do a slide animation between two Activities when then one starts the other,
public void onClick(View view) {
Intent intent = new Intent(TestAppActivity.this, SecondActivity.class);
startActivityForResult(intent, 1);
TestAppActivity.this.overridePendingTransition(R.anim.animation_enter, R.anim.animation_leave);
finish();
}
There is no animation at all. The xmls are, for enter:
<set
xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="-100%"
android:toXDelta="0%"
android:fromYDelta="0%"
android:toYDelta="0%"
android:duration="3000" />
And for leave:
<set
xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="0%"
android:toXDelta="100%"
android:fromYDelta="0%"
android:toYDelta="0%"
android:duration="3000" />
I can see what is gong wrong here. Using Android 2.3.3. Thanks.
Put the overridePendingTransition(R.anim.animation_enter, R.anim.animation_leave); after finish();.
To do an animation where the first activity go to the left and the second activity enters from the right :
slide_out_left.xml :
<?xml version="1.0" encoding="utf-8"?>
<!--
Animation : Perform animation : Out - Direction : Left
-->
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="400"
android:fromXDelta="0"
android:toXDelta="-100%p" />
</set>
slide_in_right.xml :
<?xml version="1.0" encoding="utf-8"?>
<!--
Animation : Perform animation : In - Direction : Right
-->
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="400"
android:fromXDelta="100%p"
android:toXDelta="0" />
</set>
Note : you can change android:duration if you want.
And you have to add this code :
public void onClick(View view) {
Intent intent = new Intent(TestAppActivity.this, SecondActivity.class);
startActivity(intent);
overridePendingTransition(R.anim.slide_in_right, R.anim.slide_out_left);
finish();
}
