PreLollipopTransition

Simple tool which help you to implement activity and fragment transition for pre-Lollipop devices.

Download

In your app build.gradle add

dependencies {
    compile 'com.kogitune:pre-lollipop-activity-transition:1.x.x'
}

Code

Activity

Start Activity in first activity.

findViewById(R.id.imageView).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        final Intent intent = new Intent(MainActivity.this, SubActivity.class);
        ActivityTransitionLauncher.with(MainActivity.this).from(v).launch(intent);
    }
});

Receive intent in second activity.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sub);
    ActivityTransition.with(getIntent()).to(findViewById(R.id.sub_imageView)).start(savedInstanceState);
}

If you want the exit animation, you can do like this.

private ExitActivityTransition exitTransition;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sub2);
    exitTransition = ActivityTransition.with(getIntent()).to(findViewById(R.id.sub_imageView)).start(savedInstanceState);
}
@Override
public void onBackPressed() {
    exitTransition.exit(this);
}

If you want to use startActivityForResult, you should do below.

1. Use createBundle().
2. Put Extra to intent.
3. Call overridePendingTransition after startActivityForResult.

Bundle transitionBundle = ActivityTransitionLauncher.with(MainActivity.this).from(v).createBundle();
intent.putExtras(transitionBundle);
startActivityForResult(intent, REQUEST_CODE);
// you should prevent default activity transition animation
overridePendingTransition(0, 0);

Fragment

Start fragment transition in first fragment.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.support_fragment_start, container, false);
    v.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            final EndFragment toFragment = new EndFragment();
            FragmentTransitionLauncher
                    .with(view.getContext())
                    .image(BitmapFactory.decodeResource(getResources(), R.drawable.photo))
                    .from(view.findViewById(R.id.imageView)).prepare(toFragment);
            getFragmentManager().beginTransaction().replace(R.id.content, toFragment).addToBackStack(null).commit();
        }
    });
    return v;
}

Start animation in second fragment.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.support_fragment_end, container, false);
    final ExitFragmentTransition exitFragmentTransition = FragmentTransition.with(this).to(v.findViewById(R.id.fragment_imageView)).start(savedInstanceState);
    exitFragmentTransition.startExitListening();
    return v;
}

If you want to pass argument to second fragment, you should use Fragment#getArguments() after call prepare().

final EndFragment toFragment = new EndFragment();
FragmentTransitionLauncher
        .with(view.getContext())
        .image(BitmapFactory.decodeResource(getResources(), R.drawable.photo))
        .from(view.findViewById(R.id.imageView)).prepare(toFragment);
toFragment.getArguments().putString("stringArgKey", "this is value");
getFragmentManager().beginTransaction().replace(R.id.content, toFragment).addToBackStack(null).commit();
