Libraries
Concepts
Transitions - For sharing elements between activities
void startTransition() {
Intent intent = new Intent(LoginActivity.this, LoginWithPhone.class);
Pair<View, String> p1 = Pair.create((View) ivBack, getString(R.string.transition_arrow));
Pair<View, String> p2 = Pair.create((View) ivFlag, getString(R.string.transition_ivFlag));
Pair<View, String> p3 = Pair.create((View) tvCode, getString(R.string.transition_tvCode));
Pair<View, String> p4 = Pair.create((View) tvPhoneNo, getString(R.string.transition_tvPhoneNo));
Pair<View, String> p5 = Pair.create((View) llphone, getString(R.string.transition_llPhone));
ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(this, p1, p2, p3, p4, p5);
startActivity(intent, options.toBundle());
}
ViewPagerTransformer - For performing animations when ViewPager is swiped
ViewPager.PageTransformer pageTransformer = new ViewPager.PageTransformer() {
@Override
public void transformPage(View page, float position) {
if (position < -1) {
} else if (position <= 1) {
// animate here
}
}
}
};
Overlays - For creating overlays on map
public void addOverlay(LatLng place) {
GroundOverlay groundOverlay = mMap.addGroundOverlay(new
GroundOverlayOptions()
.position(place, 100)
.transparency(0.5f)
.zIndex(3)
.image(BitmapDescriptorFactory.fromBitmap(drawableToBitmap(getDrawable(R.drawable.map_overlay)))));
}
ValueAnimator - For animating overlays and polylines
ValueAnimator tAnimator = ValueAnimator.ofFloat(0, 1);
tAnimator.setRepeatCount(ValueAnimator.INFINITE);
tAnimator.setRepeatMode(ValueAnimator.RESTART);
tAnimator.setInterpolator(new LinearInterpolator());
tAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator valueAnimator) {
// animate here
}
});
PolyLines - For drawing lines on map
PolylineOptions greyOptions = new PolylineOptions();
greyOptions.width(10);
greyOptions.color(Color.GRAY);
greyOptions.startCap(new SquareCap());
greyOptions.endCap(new SquareCap());
greyOptions.jointType(ROUND);
greyPolyLine = mMap.addPolyline(greyOptions);
How to use this project
Add your GoogleMaps and GooglePlaces key to google_maps_api.xml and turn on direction api from developer console -> You are good to go !
