I have several ImageView s in a RelativeLayout. So we have to move it when the animation is finished. To detect when the animation is finished we have to create our own animationListener inside our activity class :. So the onClickEvent will get fired again at it's new place. The animation will now move it even more down, so you might want to save the x and y in a variable, so that in the onAnimationEnd you move it not to a fix location.
In below code I am adding a image view in center on frame layout dynamically. After add I am increase scaling and set alpha to give zoom effect and after complete animation I am just translate my image view one position to another position.

Tween animation calculates the animation with information such as the start point, end point, size, rotation, and other common aspects of an animation. A tween animation can perform a series of simple transformations position, size, rotation, and transparency on the contents of a View object.
So, if you have a TextView object, you can move, rotate, grow, or shrink the text. If it has a background image, the background image will be transformed along with the text. The animation package provides all the classes used in a tween animation.
A sequence of animation instructions defines the tween animation, defined by either XML or Android code. As with defining a layout, an XML file is recommended because it's more readable, reusable, and swappable than hard-coding the animation. In the example below, we use XML. To learn more about defining an animation in your application code, instead of XML, refer to the AnimationSet class and other Animation subclasses. The animation instructions define the transformations that you want to occur, when they will occur, and how long they should take to apply.
Transformations can be sequential or simultaneous - for example, you can have the contents of a TextView move from left to right, and then rotate degrees, or you can have the text move and rotate simultaneously. Each transformation takes a set of parameters specific for that transformation starting size and ending size for size change, starting angle and ending angle for rotation, and so onand also a set of common parameters for instance, start time and duration.Who is ricky singh designer
To make several transformations happen simultaneously, give them the same start time; to make them sequential, calculate the start time plus the duration of the preceding transformation. By default, all animation instructions are applied simultaneously. To make them occur sequentially, you must specify the startOffset attribute, as shown in the example below. Screen coordinates not used in this example are 0,0 at the upper left hand corner, and increase as you go down and to the right.
Some values, such as pivotX, can be specified relative to the object itself or relative to the parent. You can determine how a transformation is applied over time by assigning an Interpolator. Android includes several Interpolator subclasses that specify various speed curves: for instance, AccelerateInterpolator tells a transformation to start slow and speed up.

I have a LinearLayout that I want to show or hide with an Animation that pushes the layout upwards or downwards whenever I change its visibility. I have created two xml files for the animations but I do not know how to start them when I change the visibility of a LinearLayout.
With the new animation API that was introduced in Android 3. 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:. You can then fade the View back out and slide it back to its original position.
I was having troubles understanding an applying the accepted answer.
I needed a little more context. Now that I have figured it out, here is a full example:.Ertugrul season 1 episode 31 urdu hd youtube
To put it into some context: If you have a layout like below, all visibility changes to the views in this container will be animated automatically. Now visibility change animations should be done via Transition API which available in support androidx package. Just call TransitionManager. Check this answer with another default and custom transition examples. You can start the correct Animation when the visibility of the LinearLayout changes by creating a new subclass of LinearLayout and overriding setVisibility to start the Animations.

Instead of immediately updating the objects position, which would cause it to blink from one area to another, you should use an animation to move it from the starting position to its end position.
Android provides ways that allow you to reposition your view objects on screen, such as the ObjectAnimator. You can provide the end position you want the object to settle on, as well as the duration of the animation. You can combine this with time interpolators to control the acceleration or decceleration of the animation.
The ObjectAnimator API provides an easy way to change the properties of a view with a specified duration. It contains static methods to create instances of ObjectAnimator depending on what type of attribute you are animating.
When repositioning your views on screen you will use the translationX and translationY attributes. Here is an example of an ObjectAnimator that moves the view to pixels from the left of the screen in 2 seconds:. This example uses the ObjectAnimator.
The first parameter is the view you want to animate. The second parameter is the property you are animating. Since the view needs to be moved horizontally, the translationX property is used.
The last parameter is the end value of the animation. Since this value isit will be that many pixels from the left of the screen.
The next method specifies how long the animation should take in milliseconds. In this example the animation will run for 2 seconds milliseconds. While using the ObjectAnimator is convenient, by default it will reposition the view using a straight line between the starting and ending points. Material design relies on curves for not only the timing of an animation, but also the spatial movement of objects on the screen.
Using curved motion can help give your app a more material feel while making your animations more interesting. The PathInterpolator class is a new interpolator introduced in Android 5. This interpolator specifies a motion curve in a 1x1 square, with anchor points at 0,0 and 1,1 and control points as specified using the constructor arguments. One way to create a PathInterpolator is by creating a Path object and supplying it to the PathInterpolator :.
Once you have created a PathInterpolator object, you can pass it to the Animator. The Animator will then use the interpolator to determine the timing or path curve when it is started.
The ObjectAnimator class has new constructors that enable you to animate coordinates along a path using two or more properties at once along with a path. For example, the following animator uses a Path object to animate the X and Y properties of a view:.Fling-based animation uses a friction force that is proportional to an object's velocity. Use it to animate a property of an object and to end the animation gradually.Android Studio Animation: Fade, Slide, Blink, Bounce, and Move
It has an initial momentum, which is mostly received from the gesture velocity, and gradually slows down. The animation comes to an end when the velocity of the animation is low enough that it makes no visible change on the device screen.
To use the physics-based support library, you must add the support library to your project as follows:. The FlingAnimation class lets you create a fling animation for an object. To build a fling animation, create an instance of the FlingAnimation class and provide an object and the object's property that you want to animate.
The starting velocity defines the speed at which an animation property changes at the beginning of the animation. The default starting velocity is set to zero pixels per second.Slab foundation
Therefore, you must define a start velocity to ensure the animation does not end right away. You can use a fixed value as the starting velocity, or you can base it off of the velocity of a touch gesture. If you choose to provide a fixed value, you should define the value in dp per second, then convert it to pixels per second.
Defining the value in dp per second allows the velocity to be independent of a device's density and form factors. For more information about converting the starting velocity to pixels per second, refer to the Converting dp per second to pixels per second section in Spring Animation. To set the velocity, call the setStartVelocity method and pass the velocity in pixels per second. The method returns the fling object on which the velocity is set. Note: Use the GestureDetector.
OnGestureListener and the VelocityTracker classes to retrieve and compute the velocity of touch gestures, respectively. You can set the minimum and the maximum animation values when you want to restrain the property value to a certain range.
This range control is particularly useful when you animate properties that have an intrinsic range, such as alpha from 0 to 1. Note : When the value of a fling animation reaches the minimum or maximum value, the animation ends. To set the minimum and maximum values, call the setMinValue and setMaxValue methods, respectively. Both methods return the animation object for which you have set the value.
The setFriction method lets you change the animation's friction. It defines how quickly the velocity decreases in an animation. Note : If you don't set the friction at the beginning of the animation, the animation uses a default friction value of 1. The example below illustrates a horizontal fling. The velocity captured from the velocity tracker is velocityX and, the scroll bounds are set to 0 and maxScroll. The friction is set to 1.
When you animate a custom property that isn't defined in pixels, you should set the minimal change of animation value that is visible to users. It determines a reasonable threshold for ending the animation. It isn't necessary to call this method when animating DynamicAnimation. ViewProperty because the minimum visible change is derived from the property.Davinci resolve film look lut

I'd like to do a simple control: a container with a view inside. If I touch the container and I move the finger, I want to move the view to follow my finger. Following the Andrey approach, if you want to move the view from its center, you only have to substract the view's half height and width to the movement.
Move a View with Animation
In the code below, I've created something called the RegionView gitwhich is a reusable container responsible for managing drag and zoom operations for each of its nested children.
Here, we manipulate the top and left coefficients of a child View 's LayoutParams to simulate movement about the diagram. By decoupling the interpretation of handling what's understood as a drag operation, and what is determined to be a scale operation, we can provide reliable manipulation of a child View.
Changed a bit a solution provided by Vyacheslav Shylkin to remove dependencies of any manually entered numbers. In this example you can move the view within it's parent bounds no matter it's size, flawless animation, and catch clicks. The reason that this solution is superior to other comments is that this approach uses a Directional Pad which calculate itself and won't relay on the View positions which is a the source for a-lot of bugs.
If you have the container inside a ScrollView or double dimension ScrollView you should add this line to the onTouch. Learn more. Asked 8 years, 1 month ago. Active 2 months ago. Viewed k times.

I am calling void every 3 seconds. It generates new position of the View and then make animation and move View to destination position. Translate animation has AnimationListener implemented.Tanque resonante serie
My problem is that animation position does not correspond with setting layoutParams positions. When animation end, it makes jump to a new position, which is about pixels far. I think the positions should be the same because I use same values next1, next2 in both situations. Please can you show me the way to find sollution? You should rather use ViewPropertyAnimator. This animates the view to its future position and you don't need to force any layout params on the view after the animation ends.
