How to start two animations at same time in android?

Question

I have two linear layouts which I want to perform two different animation on both of these layouts and at the same time.

Now its working in sequential manner. i.e, after completing one its starting another.

here is my code.

    Animation inFromRight = new TranslateAnimation(                     Animation.RELATIVE_TO_PARENT, +0.0f,                     Animation.RELATIVE_TO_PARENT, 0.0f,                     Animation.RELATIVE_TO_PARENT, 0.0f,                     Animation.RELATIVE_TO_PARENT, 0.0f);             inFromRight.setDuration(500);             inFromRight.setInterpolator(new AccelerateInterpolator());      Animation outtoLeft = new TranslateAnimation(                     Animation.RELATIVE_TO_PARENT, 0.0f,                     Animation.RELATIVE_TO_PARENT, -1.0f,                     Animation.RELATIVE_TO_PARENT, 0.0f,                     Animation.RELATIVE_TO_PARENT, 0.0f);             outtoLeft.setDuration(500);             outtoLeft.setInterpolator(new AccelerateInterpolator());      @Override         public void onClick(View v) {             switch (v.getId()) {             case R.id.menu:                             mainLayout.startAnimation(outtoLeft);                 sideBar.startAnimation(inFromRight);                                 break;             }         }  outtoLeft.setAnimationListener(new AnimationListener() {             @Override             public void onAnimationStart(Animation animation) {             }              @Override             public void onAnimationRepeat(Animation animation) {             }              @Override             public void onAnimationEnd(Animation animation) {                 mainLayout                         .setLayoutParams(new LayoutParams(                                 LayoutParams.FILL_PARENT,                                 LayoutParams.FILL_PARENT, 40));              }         });

I think you need to use an AnimationSet.

From the doc:

Represents a group of Animations that should be played together. The transformation of each individual animation are composed together into a single transform.

Here you can see how an AnimationSet is supposed to be.
