Проверьте этот проект на Dribbble
О том, как мы это сделали, читайте в нашем блоге.
##Требования
##Использование
Добавьте в свой корень build.gradle:
allprojects {
repositories {
.. .
maven { url " https://jitpack.io " }
}
}
Добавьте зависимость:
dependencies {
compile ' com.github.yalantis:todolist:v1.0.1 '
}
Добавьте BatRecyclerView
в свой XML-макет.

Создать 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 ));
}
}
}
};
Создайте BatAdapter
. Перейдите к его конструктору списка моделей и BatListener
. Обратите внимание, что ваша модель должна реализовывать интерфейс BatModel
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 ();
}
});
Инициализируйте представление переработчика
mRecyclerView . getView (). setLayoutManager ( new LinearLayoutManager ( this ));
mRecyclerView . getView (). setAdapter ( mAdapter );
ItemTouchHelper itemTouchHelper = new ItemTouchHelper ( new BatCallback ( this ));
itemTouchHelper . attachToRecyclerView ( mRecyclerView . getView ());
mRecyclerView . setAddItemListener ( mListener );
Вы можете использовать BatItemAnimator
для анимации элементов списка, как в нашей демонстрации:
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 );
Вам необходимо передать экземпляр аниматора в BatRecyclerView
и BatAdapter
. Также необходимо передать позицию перемещаемого элемента в обратном вызове move()
:
@ 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 ));
}
}
}
Дополнительные примеры использования см. в примере приложения.
cursor_drawable
и метод setCursorDrawable(@DrawableRes int res)
. Следует использовать вместо атрибута cursor_color
и метода setCursorColor(@ColorInt int color)
соответственно. Мы будем очень рады, если вы пришлете нам ссылки на свои проекты, в которых вы используете наш компонент. Просто отправьте электронное письмо по адресу [email protected]. Если у вас возникнут вопросы или предложения относительно анимации, сообщите нам.
PS Мы собираемся опубликовать еще больше крутых вещей, заключенных в код, и руководство о том, как сделать пользовательский интерфейс для iOS (Android) лучше, чем лучше. Следите за обновлениями!
