我正在创建一个过渡。单击按钮时,将执行以下方法。该方法改变了图像视图的大小,位置,并将其淡化。我正在使用TransitionManager.beginDelayedTransition(); is too fast.
来减缓过渡...但它仍然过快。我该怎么做才能减缓过渡期。谢谢。
private void moveIcon() {
View moveableIcon = findViewById(R.id.moveableImageView);
TransitionManager.beginDelayedTransition(myLayout);
// change the position of the icon
RelativeLayout.LayoutParams positionRule = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT ,
RelativeLayout.LayoutParams.WRAP_CONTENT);
positionRule.addRule(RelativeLayout.ALIGN_PARENT_TOP , RelativeLayout.TRUE);
positionRule.addRule(RelativeLayout.ALIGN_PARENT_LEFT , RelativeLayout.TRUE);
moveableIcon.setLayoutParams(positionRule);
// change the size of the button
ViewGroup.LayoutParams sizeRules = moveableIcon.getLayoutParams();
sizeRules.width = 50;
sizeRules.height = 50;
moveableIcon.setLayoutParams(sizeRules);
fadeOutAndHideImage(image);
}
private void fadeOutAndHideImage(final ImageView img)
{
Animation fadeOut = new AlphaAnimation(1, 0);
fadeOut.setInterpolator(new AccelerateInterpolator());
fadeOut.setDuration(1000);
fadeOut.setAnimationListener(new Animation.AnimationListener()
{
public void onAnimationEnd(Animation animation)
{
img.setVisibility(View.GONE);
}
public void onAnimationRepeat(Animation animation) {}
public void onAnimationStart(Animation animation) {}
});
img.startAnimation(fadeOut);
}
答案 0 :(得分:16)
尝试使用此方法:beginDelayedTransition(android.view.ViewGroup, android.transition.Transition)
AutoTransition autoTransition = new AutoTransition();
autoTransition.setDuration(3000);
TransitionManager.beginDelayedTransition(myLayout, autoTransition);
