objectanimator

问题 I have a DialogFragment which I show() when the user clicks a button on my App. I would like to set an animation to make a Z-axix rotation on the DialogFragment when it launches (i.e. a 3d card flip animation). I have succesfully used the windowAnimationStyle and the following style to do simple animations (using the View Animation framework) when the DialogFragment is shown: <style name="windowAnimationCardFlip" parent="@android:style/Animation.Dialog"> <item name="android

问题 I am aware that API level 19 supports pause() and resume() on ObjectAnimators. But in my project at API level 14, I have an ObjectAnimator which is applied to an Image view to rotate it. I want to pause the animation provided by the ObjectAnimator on touch and resume it from the place where the image view was (before touch down). So I attempted to save the current play time and cancel the object animator on my stopAnimation() function. private void stopAnimation(){ currentTime =

问题 Been doing some animation inside of a row in RecyclerView (not the row itself. Imagine expanding text) and there are times when the animation leaks to other recycled views which should not have that animation in them. Since I use property animation the scale action resizes the inner view and the leak can be seen in 2 aspects: 1) The animation will go on (This I could overcome with some guards) 2) The view has been resized and stopped in its tracks and so it will be reflected in the recycled

问题 I need to animate three elements to show additional info when the user clicks on a button. I have a label (TextView tvAvailableToPair) that slides out from under a button (Button bSearchForDevices)--both of which start with a width of fill_parent--while it simultaneously slides up. I have it changing perfectly, but it isn't animated: I've achieved that via SetLayoutParams: bSearchForDevices.setText(R.string.bSearchForDevicesDiscoveryStartedText); FrameLayout.LayoutParams lp_bSFD =

问题 I have a small game in my application, if you get something right balloons float up the screen, the balloons are views moved by 2 ObjectAnimators in an animation set, and on my main debugging device it works fine but on other devices (including tablets) it looks aweful the values are all over the place and the views violently sway from one side to the next. here is a snippet of what im doing: //2 square balloons floating sb = (ImageView)findViewById(R.id.squareballoon); sb.setVisibility(View

问题 New to android i would like to make some smooth animation. I have a file on device that contains effects and each effect is an animation. The file tells me when an effect will be played and the effect duration. The problem is i cannot chain animatorSet dynmacily : AnimatorSet mainAnimatorSet(); _listAllAnimator // Will contain every AnimatorSet(); for (int i = 0; i < listEffects; i++) { // Build animatorSet ObjectAnimaTor1... ObjectAnimaTor2... AnimatorSet animatorSet = new AnimatorSet();

问题 How is ObjectAnimator able to call the appropriate method setX if the attribute x is specified as a string? What I mean is, what technique is used to recognize that I want to animate the attribute rotation of my view and call the appropriate method setRotation of that view? I've already understood how ObjectAnimator works and have managed to use it, it is quite simple, I am just curious about the operating principles. 回答1: There are a number of ways to animate the rotation of a view: 1.

问题 Good day.I have an scenario where this half normal object animator keeps firing over and over causing heap grow and ofcourse out of memory issue at some point.Here is how it go. I have made static method for rainbow animation like this. public static ObjectAnimator startRainbowAnimation(Context context, String textToShow, final TextView textViewToAttach) { AnimatedColorSpan span = new AnimatedColorSpan(context); final SpannableString spannableString = new SpannableString(textToShow); String

问题 I want to vibrate a view with scaleX and scaleY, and I am doing it with this code, but the problem is that sometimes the view is not correctly reset, and it shows with the scale applied... I want that when the animation ends, the view must be seen with its original status always this is the code: ObjectAnimator scaleX = ObjectAnimator.ofFloat(view, "scaleX", 1f, 0.9f); scaleX.setDuration(50); scaleX.setRepeatCount(5); scaleX.setRepeatMode(Animation.REVERSE); ObjectAnimator scaleY =
