＃＃要求
＃＃用法
添加到您的根 build.gradle：
allprojects {
repositories {
.. .
maven { url " https://jitpack.io " }
}
}添加依赖：
dependencies {
compile ' com.github.yalantis:todolist:v1.0.1 '
}将BatRecyclerView添加到您的 xml 布局中
<? xml version = " 1.0 " encoding = " utf-8 " ?>
< LinearLayout xmlns : android = " http://schemas.android.com/apk/res/android "

</ LinearLayout >创建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 ));
}
}
}
};创建BatAdapter 。传递给其构造函数模型列表和BatListener 。请注意，您的模型应该实现BatModel接口
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 ();
}
});初始化您的回收者视图
mRecyclerView . getView (). setLayoutManager ( new LinearLayoutManager ( this ));
mRecyclerView . getView (). setAdapter ( mAdapter );
ItemTouchHelper itemTouchHelper = new ItemTouchHelper ( new BatCallback ( this ));
itemTouchHelper . attachToRecyclerView ( mRecyclerView . getView ());
mRecyclerView . setAddItemListener ( mListener );您可以使用BatItemAnimator对列表项进行动画处理，就像我们的演示中一样：
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 );您需要将动画师实例传递给BatRecyclerView和BatAdapter 。此外，还需要在move()回调中传递移动项目的位置：
@ 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 ));
}
}
}有关更多使用示例，请查看示例应用程序
cursor_drawable属性和setCursorDrawable(@DrawableRes int res)方法。应该分别使用而不是cursor_color属性和setCursorColor(@ColorInt int color)方法如果您可以向我们发送您使用我们组件的项目的链接，我们将非常高兴。只需发送电子邮件至 [email protected] 如果您对动画有任何疑问或建议，请告诉我们。
