}How to use this library
Add BatRecyclerView to your xml layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/gradient"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="@android:color/transparent"
app:logo="@drawable/ic_menu">
<TextView
android:id="@+id/text_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="14 Feb, 2016"
android:textColor="@android:color/white"
android:textSize="20sp" />
</android.support.v7.widget.Toolbar>
<com.yalantis.beamazingtoday.ui.widget.BatRecyclerView
android:id="@+id/bat_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
app:add_button_color="@drawable/selector_button_add"
app:hint="@string/str_add_goal"
app:radio_button_res="@drawable/selector_radio_button" />
</LinearLayout>Create BatListener
private BatListener mListener = new BatListener() {
@Override
public void add(String string) {
mGoals.add(0, new Goal(string));
mAdapter.notify(AnimationType.ADD, 0);
}
@Override
public void delete(int position) {
mGoals.remove(position);
mAdapter.notify(AnimationType.REMOVE, position);
}
@Override
public void move(int from, int to) {
if (from >= 0 && to >= 0) {
//if you use 'BatItemAnimator'
mAnimator.setPosition(to);
BatModel model = mGoals.get(from);
mGoals.remove(model);
mGoals.add(to, model);
mAdapter.notify(AnimationType.MOVE, from, to);
if (from == 0 || to == 0) {
mRecyclerView.getView().scrollToPosition(Math.min(from, to));
}
}
}
};Create BatAdapter. Pass to its constructor list of models and BatListener. Note that your model should implement BatModel interface
mAdapter = new BatAdapter(mGoals = new ArrayList<BatModel>() {{
add(new Goal("first"));
add(new Goal("second"));
add(new Goal("third"));
add(new Goal("fourth"));
add(new Goal("fifth"));
add(new Goal("sixth"));
add(new Goal("seventh"));
add(new Goal("eighth"));
add(new Goal("ninth"));
add(new Goal("tenth"));
}}, mListener);
mAdapter.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onClick(BatModel item, int position) {
Toast.makeText(ExampleActivity.this, item.getText(), Toast.LENGTH_SHORT).show();
}
});Initialize your recycler view
mRecyclerView.getView().setLayoutManager(new LinearLayoutManager(this));
mRecyclerView.getView().setAdapter(mAdapter);
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(new BatCallback(this));
itemTouchHelper.attachToRecyclerView(mRecyclerView.getView());
mRecyclerView.setAddItemListener(mListener);Extra
You can use BatItemAnimator to animate list items just like in our demo:
mAnimator = new BatItemAnimator();
mAdapter = new BatAdapter(mGoals = new ArrayList<BatModel>() {{
add(new Goal("first"));
add(new Goal("second"));
add(new Goal("third"));
add(new Goal("fourth"));
add(new Goal("fifth"));
add(new Goal("sixth"));
add(new Goal("seventh"));
add(new Goal("eighth"));
add(new Goal("ninth"));
add(new Goal("tenth"));
}}, mListener, mAnimator);
mRecyclerView.getView().setItemAnimator(mAnimator);You need to pass the animator instance to BatRecyclerView and to BatAdapter.
Also it's necessary to pass the position of the moved item in move() callback:
@Override
public void move(int from, int to) {
if (from >= 0 && to >= 0) {
mAnimator.setPosition(to);
BatModel model = mGoals.get(from);
mGoals.remove(model);
mGoals.add(to, model);
mAdapter.notify(AnimationType.MOVE, from, to);
if (from == 0 || to == 0) {
mRecyclerView.getView().scrollToPosition(Math.min(from, to));
}
}
}For more usage examples please review sample app
Changelog
Version: 1.0.1
- Cursor fixed.
cursor_drawableattribute andsetCursorDrawable(@DrawableRes int res)method added. Should be used instead ofcursor_colorattribute andsetCursorColor(@ColorInt int color)method respectively
Let us know!
Weโd be really happy if you could send us links to your projects where you use our component. Just send an email to [email protected] And do let us know if you have any questions or suggestion regarding the animation.
P.S. Weโre going to publish more awesomeness wrapped in code and a tutorial on how to make UI for iOS (Android) better than better. Stay tuned!
