A solution to this should be adding an interpolator to your animation set.

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:interpolator="@android:anim/decelerate_interpolator"
    android:shareInterpolator="true">

       <translate
          android:duration="@android:integer/config_mediumAnimTime"
          android:fromXDelta="100%"
          android:fromYDelta="0%"
          android:toXDelta="0%"
          android:toYDelta="0%" />
</set>

The interpolator will take your animation and change its speed over the duration of the animation. In the example I chose a decelerate interpolator that makes the animation starting fast and then getting slower and slower during the time of the animation.
