Android 翻译动画无法正常工作

Question

I created the following animation file full_translate.xml

<translate
    android:duration="1000"
    android:fillAfter="false"
    android:fromXDelta="0%p"
    android:toYDelta="-40%p" />

<translate
    android:duration="2000"
    android:fillAfter="false"
    android:fromXDelta="0%p"
    android:toXDelta="40%p" />

<translate
    android:duration="3000"
    android:fillAfter="false"
    android:fromXDelta="-0%p"
    android:toYDelta="40%p" />

<translate
    android:duration="4000"
    android:fillAfter="false"
    android:fromXDelta="0%p"
    android:toXDelta="-40%p" />

I want to move button from center to top then center to right, center to bottom and center to left. But the animation goes in totally wrong way. How can I play it in the correct order?
