Button is not clickable after TranslateAnimation

Question

I\'m trying to move button (with animation) upon click. I want it to move 100 pixels to the bottom on first click, 100 pixels up on second, 100 pixels to the bottom on third

View.layout() really works, thanks a lot, teoREtik. Here I provide working variant, which moves the button itself (hope it will be useful for somebody):

public class TestActivity extends Activity {
public final String TAG="TestActivity";
boolean toTop=false;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main); 
    Button b=(Button)findViewById(R.id.button);
    b.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            int modifierY;
            if(toTop) modifierY=-100; 
            else modifierY=100;
            Animation translateAnimation=new TranslateAnimation(0, 0, 0, modifierY);
            translateAnimation.setDuration(1000);
            translateAnimation.setFillEnabled(true);
            MyAnimationListener listener=new MyAnimationListener(v, modifierY,TestActivity.this);
            translateAnimation.setAnimationListener(listener);

            v.startAnimation(translateAnimation);
            toTop=!toTop;
        }
    });
}

We have to invoke View.layout() only when animation is finished, so we need to use AnimationListener.onAnimationEnd. In order to be able to specify button and modifierY, I created my custom AnimationListener, which receives button and modifierY in constructor:

public class MyAnimationListener implements AnimationListener{
View mView;
int mModifier;
Context mContext;

public MyAnimationListener(View v, int modifier, Context c){
    mView=v;
    mModifier=modifier;
    mContext=c;
}
public void onAnimationEnd(Animation animation) {
    int[] pos={mView.getLeft(),mView.getTop()+mModifier,mView.getRight(),mView.getBottom()+mModifier};
    mView.layout(pos[0],pos[1],pos[2],pos[3]);
    Toast.makeText(mContext, "left="+mView.getLeft()+"\ntop="+mView.getTop(), Toast.LENGTH_SHORT).show();
}

public void onAnimationRepeat(Animation animation) {}

public void onAnimationStart(Animation animation) {}

}
