Multiple Shared Elements

Question

I have the following situation inside of a soccer application.
We want to implement the shared elements between all these activities.

Beyond any doubt, the problem is because you are changing transitionName of the view that you want to share from second Activity to third. But you should simply keep that transitionName in the second Activity but change transitionName of the view in third Activity's onCreate method, according to what we want to share from second Activity.

So let's keep our transition from first Activity to second, as it's working as expected. Let's look at the second Activity: we just need to send the transitionName of view, that we want to share as an extra of Intent to third Activity and then assign this value programmatically to the shared view in third Activity.

So here is the code of our second Activity:

View homeTeam = findViewById(R.id.home_team_detail);
View awayTeam = findViewById(R.id.away_team_detail);

View.OnClickListener onTeamClickListener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Activity activityContext = MultipleElementsDetail.this;
        final ActivityOptions options = ActivityOptions.makeSceneTransitionAnimation(
                activityContext,
                Pair.create(v, v.getTransitionName()));
        startActivity(new Intent(activityContext, SingleElementDetail.class)
           .putExtra("shared_element_transition_name", v.getTransitionName()), options.toBundle());
    }
};

homeTeam.setOnClickListener(onTeamClickListener);
awayTeam.setOnClickListener(onTeamClickListener);

So what I did here is just created the same OnClickListener for both teams, which creates shared transition, and starts new activity with Intent having transitionName of shared view as an extra.

And then in third Activity I've just get this extra from Intent and set it as a transitionName of shared view:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_single_element_detail);

    View team = findViewById(R.id.team_single);

    String transitionName = getIntent().getStringExtra("shared_element_transition_name");
    if (!TextUtils.isEmpty(transitionName)) {
        ViewCompat.setTransitionName(team, transitionName);
    }
}

And as a result we have something like this (I've used explode transition to better see the difference between activities):

Hope that helps and exactly the same what you want! :)
