Despite this, over time your S9 or S9+ may slow down a bit more than you would like. The Galaxy S9 is an amazing smartphone, with a number of advanced features. With this XML saved as hyperspace_jump.xml in the res/anim/ĭirectory of the project, the following code will reference it and apply it to an ImageView object from the layout.ĪnimationUtils.loadAnimation(this, R.anim.hyperspace_jump).Samsung just launched their Galaxy S9 flagship, with preorders shipping in the US already. Each one has an attribute value that can be Tells a transformation to start slow and speed up. Specify various speed curves: for instance, AccelerateInterpolator Android includes several Interpolator subclasses that You can determine how a transformation is applied over time by assigning an Interpolator. Be sure to use the proper format for what you want ("50" for 50% relative to the parent, Some values, such as pivotX, can be specified relative to the object itself or relative to the Increase as you go down and to the right. Screen coordinates (not used in this example) are (0,0) at the upper left hand corner, and
The following XML from one of the ApiDemos is used to stretch, then simultaneously spin and Specify the startOffset attribute, as shown in the example below. To make them occur sequentially, you must By default, allĪnimation instructions are applied simultaneously. Groups of these elements (which may include another ). , interpolator element, or element that holds
The file must have a single root element: this will be either a single The animation XML file belongs in the res/anim/ directory of your Android Plus the duration of the preceding transformation. Simultaneously, give them the same start time to make them sequential, calculate the start time Parameters (for instance, start time and duration). Set of parameters specific for that transformation (starting size and ending size for sizeĬhange, starting angle and ending angle for rotation, and so on), and also a set of common
for example, you can have the contents of a TextView move from left to right, and then rotateġ80 degrees, or you can have the text move and rotate simultaneously. Transformations can be sequential or simultaneous Occur, and how long they should take to apply. The animation instructions define the transformations that you want to occur, when they will Learn more about defining an animation in your application code, instead of XML, refer to theĪnimationSet class and other Animation subclasses.) Reusable, and swappable than hard-coding the animation. As with defining a layout, an XML file is recommended because it's more readable, The animation package provides all the classes used in a tween animation.Ī sequence of animation instructions defines the tween animation, defined by either XML orĪndroid code. If it has aīackground image, the background image will be transformed along with the text. So, if you have a TextView object, you can move, rotate, grow, or shrink the text.
Tween animationĬalculates the animation with information such as the start point, end point, size, rotation, andĪ tween animation can perform a series of simple transformations (position, size, rotation,Īnd transparency) on the contents of a View object. You can use the view animation system to perform tweened animation on Views. Create an implementation with older APIs.
