Start your Activity with Slide Animation

How to do this?

Let’s say you have two activities.

• MovieDetailActivity
• AllCastActivity

And on click of a Button, this happens.

You can achieve this in 3 simple steps

1) Enable Content Transition

Go to your style.xml and add this line to enable the content transition.

<item name=”android:windowContentTransitions”>true</item>

2) Write Default Enter and Exit Transition for AllCastActivity

public void setAnimation()
 {
    if(Build.VERSION.SDK_INT>20) {
      Slide slide = new Slide();
      slide.setSlideEdge(Gravity.LEFT);
      slide.setDuration(400);
      slide.setInterpolator(new DecelerateInterpolator());
      getWindow().setExitTransition(slide);
      getWindow().setEnterTransition(slide);
 }

3) Start Activity with Intent

Write this method in `MovieDetailActivity` to start `AllCastActivity`

public void startActivity(){
   Intent i = new Intent(this,AllCastActivity.class);
    if(Build.VERSION.SDK_INT>20){ 
         ActivityOptions options =          
         ActivityOptions.makeSceneTransitionAnimation(this);
         startActivity(i,options.toBundle());
    }else {
         startActivity(i);
    } 
}

Most important!

put your `setAnimation()`method before `setContentView()` method otherwise the animation will not work.
So your AllCastActivity.java should look like this

class AllCastActivity extends AppcompatActivity {
   @Override
   protected void onCreate(Bundle savedInstaceState){
         super.onCreate(savedInstaceState);
         setAnimation();
         setContentView(R.layout.all_cast_activity);
       
         ...............
    }
    //Your Slide animation
    public void setAnimation(){
          if(Build.VERSION.SDK_INT>20) {
            Slide slide = new Slide();
            slide.setSlideEdge(Gravity.LEFT);
            slide.setDuration(400);         
            slide.setInterpolator(new DecelerateInterpolator());                                                         
            getWindow().setExitTransition(slide);
            getWindow().setEnterTransition(slide);
         }
     }
}

And you are done.
