如何使用缓动添加反弹动画？

Question

I want to add animate a linearlayout to vertically going up and then easing to it's original position. Like in this . However, I only know how to have the linearlayout go up without the easing.

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="800"
        android:fromYDelta="50%p"
        />
</set>

This is the animation xml file that I added for vertically going up.

You should use overshoot_interpolator ,

<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:interpolator="@android:anim/overshoot_interpolator">
    <translate
            android:duration="800"
            android:fromYDelta="50%p"
    />
</set>

If you want more customization, you could run multiple translate animations in sequence. You could use android:startOffset to delay the animations and run them 'sequentially'. ( Example )
