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();

Resources

A simple, reactive Android library based on RxJava that monitors app state changes. It notifies subscribers every time the app goes into background and comes back into foreground.

A typical use case is, for example, session tracking for analytics purposes or suppressing push notifications when the app is currently visible to the user.

A simple, animated icon to use when interacting with the fingerprint reader.

ViewPager which was optimized for scrolling app intros or making your CV app.

A reactive wrapper around Android's fingerprint API that handles encrypting/decrypting sensitive data using a fingerprint.

This library provides possibility to easily integrate lock pattern protection into application. A lot of items are available for customization.

An implementation of a TextView with support of Paratype & Google PT font family.
