Button doesn't work after animation

I have created a view in android and I need to animate it from bottom to top and vice versa. I managed it with TranslateAnimation. But the problem is I have multiple buttons on the view. When animated there touch points remain in their original location and do not move to a new position. So when I click the original position of the button again, the animation starts from top to bottom, but the button is not there.

I have searched the internet and people say call view.layout with parameters, but my question is how to get the last position of the view because I tried to extract the post to the beginning of the animation and the end of the animation remains the same.

Also please not give an answer that it doesn't actually move the view, it creates a copy and moves it, etc. because I have searched but could not find the correct solution described or implemented.

Here is the code:

import android.content.Context;
import android.graphics.Matrix;
import android.view.LayoutInflater;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.Transformation;
import android.view.animation.TranslateAnimation;
import android.widget.ImageButton;
import android.widget.LinearLayout;
import com.Card_Android.R;

public class GameMenuScreenAnimated extends LinearLayout {

private final View mainView;

public GameMenuScreenAnimated(Context context,
        final GameViewController dashboardVC) {

    super(context);
    LayoutInflater inflater = LayoutInflater.from(context);
    mainView = inflater.inflate(R.layout.main_menu, this);

    ImageButton btn = (ImageButton) mainView.findViewById(R.id.trade);
    btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            System.out.println("yaaaaaay!!!!");

        }
    });

    slideDown(mainView);
}

public View getMainView() {
    return mainView;
}

private void slideUp(final View view) {

    Animation slide = new TranslateAnimation(Animation.RELATIVE_TO_SELF,
            0.0f, Animation.RELATIVE_TO_SELF, 0.0f,
            Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
            0.5f);
    slide.setDuration(1000);
    slide.setFillAfter(true);
    slide.setFillEnabled(true);
    view.startAnimation(slide);
    slide.setAnimationListener(new AnimationListener() {

        @Override
        public void onAnimationStart(Animation animation) {
            int[] startPosition = new int[2];
            view.getLocationOnScreen(startPosition);
            System.out.println("onAnimationStart " + startPosition[0]
                    + " , " + startPosition[1]);
        }

        @Override
        public void onAnimationRepeat(Animation animation) {
        }

        @Override
        public void onAnimationEnd(Animation animation) {
             int[] endPosition = new int[2];
             view.getLocationOnScreen(endPosition);
             System.out.println("onAnimationEnd " + endPosition[0] + " , "
             + endPosition[1]);

        }

    });

}

private final AnimationListener slideDownAnimationListener = new AnimationListener() {
    @Override
    public void onAnimationStart(Animation animation) {
    }

    @Override
    public void onAnimationRepeat(Animation animation) {
    }

    @Override
    public void onAnimationEnd(Animation animation) {
        final int left = mainView.getLeft();
        final int top = mainView.getTop();
        final int right = mainView.getRight();
        final int bottom = mainView.getBottom();
        mainView.layout(left, (int) Math.round(top + 0.25 * top), right,
                (int) Math.round(bottom + 0.25 * bottom));
    }
};

private final Animation slideDownAnimation = new TranslateAnimation(
        Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF, 0.0f,
        Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF, 0.25f);

private void slideDown(final View view) {
    slideDownAnimation.setDuration(1000);
    slideDownAnimation.setFillAfter(true);
    slideDownAnimation.setFillEnabled(true);
    slideDownAnimation.setAnimationListener(slideDownAnimationListener);
    view.startAnimation(slideDownAnimation);
}
}

Selectable xml

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/evolution">

<item android:state_focused="true" android:drawable="@drawable/menu_on" /> <!-- focused -->
<item android:drawable="@drawable/menu_on" /> <!-- default -->
</selector>

      

        
        
        
      

    

All I want to do is create a simple menu with a few buttons that can be moved and clicked on.
