问题 I'm attempting to animate the removal of a ListView item using this: mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> adapterView, final View view, final int i, long l) { view.animate().setDuration(500).x(-view.getWidth()).alpha(0f); adapter.remove(tasks.get(i)); adapter.notifyDataSetChanged(); } }); It does not work. I basically followed the advice of the 4th answer from the top of this post: How to Animate Addition or

问题 I have an app that displays multiple circles and animates the radius from 0 to 300. The problem I am having is that it displays multiple circles slowly increasing the radius with each circle. I want only one circle drawn that increases the radius. Here is my code. public class SplashLaunch extends View{ Handler cool = new Handler(); DrawingView v; Paint newPaint = new Paint(); int randomWidthOne = 0; int randomHeightOne = 0; private float radiusOne = 300; final int redColorOne = Color.RED;

问题 I have an infinite translate animation applied to an ImageView : Animation animation = new TranslateAnimation(0, 0, -500, 500); animation.setDuration(4000); animation.setFillAfter(false); myimage.startAnimation(animation); animation.setRepeatCount(Animation.INFINITE); What I have noticed is that the translation process is slower when the image is near the starting and ending point compared to when its near half the distance (middle point). I guess the velocity for translate animations on

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...
