You cant do it within the xml itself, you need to create an instance of that ImageViewin your activity and call its setX()or setY()method to set the coordinates.
您不能在 xml 本身内执行此操作，您需要ImageView在您的活动中创建该实例的实例并调用其setX()或setY()方法来设置坐标。
Bewarethat every screen has different number of pixels, you might have different result on different devices.
请注意，每个屏幕都有不同的像素数，您在不同的设备上可能会得到不同的结果。
Sample:
样本：
ImageView s = (ImageView) findViewById(R.id.your_id);
s.setY(number);
s.setX(number);

TranslateAnimation animation = new TranslateAnimation(0.0f, 50.0f, 0.0f, 0.0f);
animation.setDuration(700);
animation.setRepeatCount(5);
animation.setRepeatMode(2);
animation.setFillAfter(true);
image.startAnimation(animation);
