我在开源应用程序中创建了一个相当复杂的结束动画。
如果调用onBackPressed()方法,应用程序将为视图设置动画并关闭。似乎有一个记忆韭菜,因为它后来不会停止分配新的ram。如果我删除动画并只是调用普通onBackPressed,我就不会有上述行为。
这是我在onBackPressed方法中调用的代码:
//make global var :D
ViewPropertyAnimator hideFabAnimator;
@Override
public void onBackPressed() {
mFabDownloadButton.animate()
.translationX(0)
.setDuration(ANIMATION_DURATION_MEDIUM)
.start();
//move the share fab below the normal fab (58 because this is the margin top + the half
mFabShareButton.animate()
.translationX(0)
.setDuration(ANIMATION_DURATION_MEDIUM)
.setListener(new CustomAnimatorListener() {
@Override
public void onAnimationEnd(Animator animation) {
//create the fab animation and hide fabProgress animation, set an delay so those will hide after the shareFab is below the main fab
hideFabAnimator = Utils.hideViewByScaleXY(mFabButton)
.setDuration(ANIMATION_DURATION_MEDIUM);
Utils.hideViewByScaleXY(mFabDownloadButton)
.setDuration(ANIMATION_DURATION_MEDIUM)
.start();
Utils.hideViewByScaleXY(mFabShareButton)
.setDuration(ANIMATION_DURATION_MEDIUM)
.start();
Utils.hideViewByScaleXY(mFabProgress)
.setDuration(ANIMATION_DURATION_MEDIUM)
.start();
//add listener so we can react after the animation is finished
hideFabAnimator.setListener(new CustomAnimatorListener() {
@Override
public void onAnimationEnd(Animator animation) {
try {
ViewPropertyAnimator hideFabAnimator = Utils.hideViewByScaleY(mTitleContainer);
hideFabAnimator.setListener(new CustomAnimatorListener() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
coolBack()
}
});
} catch (Exception ex) {
super.onAnimationEnd(animation);
coolBack()
}
}
});
hideFabAnimator.start();
super.onAnimationEnd(animation);
}
})
.start();
}
/**

*/
private void coolBack() {
try {
super.onBackPressed();
} catch (Exception e) {
}
}
您可以在此处找到相同的源@github:https://github.com/mikepenz/wall-splash-android/blob/master/app/src/main/java/com/mikepenz/unsplash/activities/DetailActivity.java#L701
我尝试过很多不同的东西。但没有任何帮助。
感谢。

所以我能够解决这个问题。似乎如果你在没有animationListener的情况下使用普通动画,它可能会发生(它会发生)动画无法完成并且将保持" in-tact"。因此,即使活动已经关闭,它似乎仍在后台处理某些内容。
所以我能够通过定义一个监听器来解决这个问题 - "链"并检查我的所有动画是否完成。
以下是有效的代码:
@Override
public void onBackPressed() {
mFabDownloadButton.animate()
.translationX(0)
.setDuration(ANIMATION_DURATION_MEDIUM)
.setListener(animationFinishListener1)
.start();
//move the share fab below the normal fab (58 because this is the margin top + the half
mFabShareButton.animate()
.translationX(0)
.setDuration(ANIMATION_DURATION_MEDIUM)
.setListener(animationFinishListener1)
.start();
}
private CustomAnimatorListener animationFinishListener1 = new CustomAnimatorListener() {
private int animateFinish1 = 0;
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
process();
}
@Override
public void onAnimationCancel(Animator animation) {
super.onAnimationCancel(animation);
process();
}
private void process() {
animateFinish1 = animateFinish1 + 1;
if (animateFinish1 == 2) {
//create the fab animation and hide fabProgress animation, set an delay so those will hide after the shareFab is below the main fab
Utils.hideViewByScaleXY(mFabDownloadButton)
.setDuration(ANIMATION_DURATION_MEDIUM)
.setListener(animationFinishListener2)
.start();
Utils.hideViewByScaleXY(mFabShareButton)
.setDuration(ANIMATION_DURATION_MEDIUM)
.setListener(animationFinishListener2)
.start();
Utils.hideViewByScaleXY(mFabProgress)
.setDuration(ANIMATION_DURATION_MEDIUM)
.setListener(animationFinishListener2)
.start();
Utils.hideViewByScaleXY(mFabButton)
.setDuration(ANIMATION_DURATION_MEDIUM)
.setListener(animationFinishListener2)
.start();
}
}
};
private CustomAnimatorListener animationFinishListener2 = new CustomAnimatorListener() {
private int animateFinish2 = 0;
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
process();
}
@Override
public void onAnimationCancel(Animator animation) {
super.onAnimationCancel(animation);
process();
}
private void process() {
animateFinish2 = animateFinish2 + 1;
if (animateFinish2 == 4) {
ViewPropertyAnimator hideFabAnimator = Utils.hideViewByScaleY(mTitleContainer);
hideFabAnimator.setListener(new CustomAnimatorListener() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
coolBack();
}
});
}
}
};
/**
*
*/
private void coolBack() {
try {
super.onBackPressed();
} catch (Exception e) {
// ew;
}
}
所以我会继续计算我的动画,并且只会在第一个"批次"动画完成后,我将继续第二批"批次"动画。一旦完成,我将完成活动。

我有一个动画的类似泄漏。在我的情况下,我使用
scaleY.setRepeatCount(1);
scaleY.setRepeatMode(ValueAnimator.REVERSE);
for setRepeatCount我之前使用过INFINITY,它也从不用于动画,甚至在调用显式的cancle()或end()之后也没有。我只是将其改为1(它不再是无限的,但我可以忍受它)。 刚刚添加了这个答案,也有人遇到了这个问题。
