Delays within the Animation (TranslateAnimation)
提问by ymotov
Is there a way to have the Animationpause for a half a second?
有没有办法让Animation停顿半秒？
I am trying to make an infinite animation using the TranslateAnimationAPI. So, I use the RepeatCountas Infinite. I also noticed that there's a setStartOffset(...)method that covers the case when I'd like to have a delay in starting the animation. However, I can't find a way to have a delay before each 'restart'. Since animation is gonna happen infinite amount of times, every time the animation restarts I need to put a delay in.
我正在尝试使用TranslateAnimationAPI制作无限动画。所以，我使用RepeatCountas Infinite。我还注意到有一种setStartOffset(...)方法可以涵盖我想要延迟启动动画的情况。但是，我找不到在每次“重新启动”之前延迟的方法。由于动画会发生无限次，每次动画重新启动时我都需要延迟。
Any ideas?
有任何想法吗？
Thanks!!
谢谢！！

Here is an example:
下面是一个例子：
First the layout (main.xml) with an image we would like to animate:
首先是带有我们想要动画的图像的布局 (main.xml)：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" />
</LinearLayout>
Next one is the animation. Placed in res/anim and is called anim_img.xml. The file contains the translation animation with android:startOffset="500" (in millisec). This will set the offset, which is used every time animation starts:
下一个是动画。放置在 res/anim 中，名为 anim_img.xml。该文件包含带有 android:startOffset="500"（以毫秒为单位）的翻译动画。这将设置每次动画开始时使用的偏移量：
<?xml version="1.0" encoding="utf-8"?>
<set>
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fromXDelta="0%"
android:fromYDelta="0%"
android:toXDelta="0%"
android:toYDelta="100%"
android:zAdjustment="top"
android:repeatCount="infinite"
android:startOffset="500"/>
</set>
And last but not least - the activity. Which starts the animation:
最后但并非最不重要的 - 活动。启动动画：
public class StackOverflowActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView iv_icon = (ImageView) findViewById(R.id.imageView1);
Animation a = AnimationUtils.loadAnimation(this, R.anim.anim_img);
a.setFillAfter(true);
a.reset();
iv_icon.startAnimation(a);
}
}

To achieve a pause of x milliseconds between each restart:
要在每次重新启动之间实现 x 毫秒的暂停：
myAnimation.setAnimationListener(new AnimationListener(){
@Override
public void onAnimationStart(Animation arg0) {
}
@Override
public void onAnimationEnd(Animation animation) {
}
@Override
public void onAnimationRepeat(Animation animation) {
myAnimation.setStartOffset(x);
}
});

myanimation.setStartDelay(int);
myanimation.setStartDelay(int);
