Android实现控件缩放的方法有多种,下面介绍几种常见的方法:
ScaleAnimation scaleAnimation = new ScaleAnimation(1f, 0.5f, 1f, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); scaleAnimation.setDuration(1000); scaleAnimation.setFillAfter(true); view.startAnimation(scaleAnimation);
ObjectAnimator scaleX = ObjectAnimator.ofFloat(view, "scaleX", 1f, 0.5f); ObjectAnimator scaleY = ObjectAnimator.ofFloat(view, "scaleY", 1f, 0.5f); AnimatorSet animatorSet = new AnimatorSet(); animatorSet.setDuration(1000); animatorSet.playTogether(scaleX, scaleY); animatorSet.start();
Matrix matrix = new Matrix(); matrix.postScale(0.5f, 0.5f); view.setImageMatrix(matrix);
以上是几种常见的实现控件缩放效果的方法,开发者可以根据具体需求选择合适的方法来实现控件的缩放。
