Following is my scenario.
I have an Activity MainActivity which has one FAB. When the user clicks on FAB, I open a full screen DialogFragment. I want to open the DialogFragment with some transitions.
Here is the code that I have tried so far.
//MainActivity.java
 final FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
 fab.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View view) {
    ReviewDialog reviewDialog = ReviewDialog.newInstance();
    Slide slide = new Slide();
    slide.setSlideEdge(Gravity.LEFT);
    slide.setDuration(1000);
    reviewDialog.setEnterTransition(slide);
    Bundle bundle =ActivityOptions.makeSceneTransitionAnimation(ScrollingActivity.this)
        .toBundle();
    reviewDialog.setArguments(bundle);
    reviewDialog.show(getSupportFragmentManager(),"review");
  }
});
And here is the code of the DialogFragment ReviewDialog.
   //ReviewDialog.java
    public class ReviewDialog extends DialogFragment {
  static ReviewDialog newInstance() {
    ReviewDialog f = new ReviewDialog();
    // Supply num input as an argument.
    Bundle args = new Bundle();
    f.setArguments(args);
    return f;
  }
  @Override
  public void onActivityCreated(Bundle arg0) {
    super.onActivityCreated(arg0);
    Slide slide = new Slide();
    slide.setSlideEdge(Gravity.LEFT);
    slide.setDuration(1000);
    getDialog().getWindow().setEnterTransition(slide);
    getDialog().getWindow().setExitTransition(slide);
    getDialog().getWindow().setReenterTransition(slide);}
  @Override
  public void onCreate(Bundle bundle){
    super.onCreate(bundle);
    setStyle(DialogFragment.STYLE_NORMAL,R.style.DialogTheme);
  }
  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
                           Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.dialog_review, container, false);
    return v;
  }
}
Also I have set the following property in my AndroidManifest.xml
<item name="android:windowContentTransitions">true</item>
The problem is when the ReviewDialog is started, it doesn't show any transitions. I am able to show transitions between different activities but finding it very hard to show transition between Activity and Fragment. How to show transitions when a DialogFragment is started ?
