I'm trying to do something similar to the YouTube Music app where you can tap on the mini-player at the bottom to open a big player, like in this video:
I have an Activity with the mini-player as a Fragment, like this:
I'm not sure how to implement the transition to a large player.
public class MainActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
getSupportFragmentManager()
.beginTransaction()
.add(R.id.media_player, new PlayerFragment(), "media_player")
.commit();
}
}
public class PlayerFragment extends Fragment {
@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = LayoutInflater.from(this).inflate(R.layout.fragment_player, null);
return view;
}
}
main_activity:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
...
<androidx.fragment.app.FragmentContainerView
android:id="@+id/media_player"
android:layout_width="match_parent"
android:layout_height="75dp"
android:layout_gravity="bottom"
/>
</LinearLayout>
fragment_player:
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/player_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true"
android:orientation="horizontal">
...
<ImageView
android:id="@+id/player_play_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:src="@drawable/ic_player_play_image"
android:padding="5dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toStartOf="@+id/player_fast_forward"
app:layout_constraintStart_toEndOf="@+id/player_rewind"
app:layout_constraintTop_toBottomOf="@+id/player_title" />
...
</androidx.constraintlayout.widget.ConstraintLayout>
