问题
I am working on Shared elements Transitions in Android and have executed the animations perfectly. The problem I am facing is when passing data using Intents. So, I basically start Intent from ActivityA, which is the first screen containing a recycler view, do an ImageTransform using TransitionName and start ActivityB, which contains a details activity containing a ViewPager. Now, when I press back button, ActivityB calls finishAfterTransition in which I create an Intent and set the result as follows:
@Override
public void finishAfterTransition() {
Intent data=new Intent();
data.putExtra("Student", new Student("id", "name", "grade"));
data.putExtra("CURRENT_POSITION", 2);
data.putExtra("LAST_POSITION", 5);
setResult(ProfileConstant.ResponseCode.COMPLETE_PROFILE, data);
finishAfterTransition = true;
super.finishAfterTransition();
}
Student Model is the same as answered at this link. In ActivityA, I am using
public void onActivityReenter(int resultCode, Intent data) {
Student sr = (Student) bundle.getParcelable("Student");
current_position = bundle.getInt("CURRENT_POSITION", -1);
int last_position = bundle.getInt("LAST_POSITION", -1);
}
which throws the following exception.
All the Animations works completely fine, when I dont pass the Student Object and everything works as intended, without throwing any exception. I am also using setEnterSharedElementCallback and setExitSharedElementCallback for mapping the views and their transition name, which has nothing to do with the Intent.
I don't understand why passing a parcelable object in Intent does not work with Transitions. Is there a workaround or am I doing it the wrong way? Would appreciate suggestions. I have presented only relevent code here.
