我正在尝试将我的图片翻译到另一个指定的地方..我在这里尝试了代码。但是，它的翻译方式错了..
请有人帮我解决这个问题..

第一，我建议你使用NineOldDroid来查看动画，因为它易于使用，你可以摆脱各自的翻译点。
例如翻译
AnimatorSet set = new AnimatorSet();
set.playTogether(
ObjectAnimator.ofFloat(dragView, "x", holderLoc[0]),
ObjectAnimator.ofFloat(dragView, "y", holderLoc[1]));
set.setDuration(500).start();
set.addListener(new AnimatorListener() {
@Override
public void onAnimationStart(Animator animation) {
}
@Override
public void onAnimationRepeat(Animator animation) {
}
@Override
public void onAnimationEnd(Animator animation) {
}
@Override
public void onAnimationCancel(Animator animation) {
}
});
其次你说你的坐标是正确的，所以我没有检查过，但是你在窗口中获得了View的坐标，当你将它移动到那个位置时，变量相应地设置为父视图。所以从那里做一件事
1）或者制作相对布局的视图直接子视图
2）根据父母计算正确的值。

您想将imageTwo翻译为imageThree，我是对的吗？
如果是这样，传递给TranslateAnimation's构造函数的参数是错误的。
以下是四个参数：
float fromXDelta ==> starting xValue RELATIVE to the view
-> ZERO in your case // imageTwo starts from where it is
float toXDelta ==> final xValue RELATIVE to the view
-> (destinationX - sourceX) in your case // imageTwo travels this much in X
float fromYDelta ==> starting yValue RELATIVE to the view
-> ZERO in your case // imageTwo starts from where it is
float toYDelta ==> final yValue RELATIVE to the view
-> (destinationY - sourceY) in your case // imageTwo travels this much in Y
R.id.imageView2的修改后的案例：
case R.id.imageView2 :
transAnimation= new TranslateAnimation(0f,
(destinationX - sourceX),
0f,
(destinationY - sourceY));
transAnimation.setDuration(3000);
v.startAnimation(transAnimation);
break;
如果您希望imageTwo在动画后“留下”，请将AnimationListener附加到transAnimation并相应地更改LayoutParams imageTwo onAnimationEnd readLocation(String str) 1}}。
还有一件事：查看对此（Link）答案的评论。你确定你获得了有效的头寸价值吗？安全的做法是从onClick(View)致电@Override
public void onClick(View v) {
readLocation("onClick");
switch(v.getId()) {
....
....
}
}
：
locationOnScreen(int[])并且，locationInWindow(int[])足以满足您的目的。 <{1}}不是必需的。
