##Requisitos
##Uso
Adicione ao seu build.gradle raiz:
allprojects {
repositories {
.. .
maven { url " https://jitpack.io " }
}
}
Adicione a dependência:
dependencies {
compile ' com.github.yalantis:todolist:v1.0.1 '
}
Adicione BatRecyclerView
ao seu layout xml
<? 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 >
Criar 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 ));
}
}
}
};
Crie BatAdapter
. Passe para sua lista de construtores de modelos e BatListener
. Observe que seu modelo deve implementar a interface 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 ();
}
});
Inicialize sua visualização do reciclador
mRecyclerView . getView (). setLayoutManager ( new LinearLayoutManager ( this ));
mRecyclerView . getView (). setAdapter ( mAdapter );
ItemTouchHelper itemTouchHelper = new ItemTouchHelper ( new BatCallback ( this ));
itemTouchHelper . attachToRecyclerView ( mRecyclerView . getView ());
mRecyclerView . setAddItemListener ( mListener );
Você pode usar BatItemAnimator
para animar itens de lista como em nossa demonstração:
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 );
Você precisa passar a instância do animador para BatRecyclerView
e para BatAdapter
. Também é necessário passar a posição do item movido no callback 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 ));
}
}
}
Para obter mais exemplos de uso, revise o aplicativo de exemplo
cursor_drawable
e método setCursorDrawable(@DrawableRes int res)
adicionados. Deve ser usado em vez do atributo cursor_color
e do método setCursorColor(@ColorInt int color)
respectivamente Ficaríamos muito felizes se você pudesse nos enviar links para seus projetos onde você usa nosso componente. Basta enviar um e-mail para [email protected] e nos avisar se tiver alguma dúvida ou sugestão em relação à animação.
