导入依赖:

 dependencies {   // ...    compile 'me.everything:overscroll-decor-android:1.0.4' }

RecyclerView

支持线性布局和网格布局管理器(即所有原生Android布局)。可以轻松适应支持自定义布局管理器。

 RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);  // Horizontal OverScrollDecoratorHelper.setUpOverScroll(recyclerView, OverScrollDecoratorHelper.ORIENTATION_HORIZONTAL); // Vertical OverScrollDecoratorHelper.setUpOverScroll(recyclerView, OverScrollDecoratorHelper.ORIENTATION_VERTICAL);

ListView

 ListView listView = (ListView) findViewById(R.id.list_view); OverScrollDecoratorHelper.setUpOverScroll(listView);

GridView

 GridView gridView = (GridView) findViewById(R.id.grid_view); OverScrollDecoratorHelper.setUpOverScroll(gridView);

ViewPager

 ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager); OverScrollDecoratorHelper.setUpOverScroll(viewPager);

ScrollView, HorizontalScrollView

 ScrollView scrollView = (ScrollView) findViewById(R.id.scroll_view); OverScrollDecoratorHelper.setUpOverScroll(scrollView); HorizontalScrollView horizontalScrollView = (HorizontalScrollView) findViewById(R.id.horizontal_scroll_view); OverScrollDecoratorHelper.setUpOverScroll(horizontalScrollView);

Any View - Text, Image…

 View view = findViewById(R.id.demo_view);   // Horizontal OverScrollDecoratorHelper.setUpStaticOverScroll(view, OverScrollDecoratorHelper.ORIENTATION_HORIZONTAL); // Vertical OverScrollDecoratorHelper.setUpStaticOverScroll(view, OverScrollDecoratorHelper.ORIENTATION_VERTICAL);

高级用法

 // Horizontal RecyclerView RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view); new HorizontalOverScrollBounceEffectDecorator(new RecyclerViewOverScrollDecorAdapter(recyclerView));  // ListView (vertical) ListView listView = (ListView) findViewById(R.id.list_view); new VerticalOverScrollBounceEffectDecorator(new AbsListViewOverScrollDecorAdapter(listView));  // GridView (vertical) GridView gridView = (GridView) findViewById(R.id.grid_view); new VerticalOverScrollBounceEffectDecorator(new AbsListViewOverScrollDecorAdapter(gridView));  // ViewPager ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager); new HorizontalOverScrollBounceEffectDecorator(new ViewPagerOverScrollDecorAdapter(viewPager));  // A simple TextView - horizontal View textView = findViewById(R.id.title); new HorizontalOverScrollBounceEffectDecorator(new StaticOverScrollDecorAdapter(view));

RecyclerView 使用 ItemTouchHelper 进行拖动

从版本1.0.1起,效果可以与RecyclerView内置的滑动机制(基于ItemTouchHelper)平滑运行。但是,还需要一些很少显式的配置工作:

 // Normally you would attach an ItemTouchHelper & a callback to a RecyclerView, this way: RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view); ItemTouchHelper.Callback myCallback = new ItemTouchHelper.Callback() {   ... }; ItemTouchHelper myHelper = new ItemTouchHelper(myCallback); myHelper.attachToRecyclerView(recyclerView);  // INSTEAD of attaching the helper yourself, simply use the dedicated adapter new VerticalOverScrollBounceEffectDecorator(new RecyclerViewOverScrollDecorAdapter(recyclerView, myCallback));

滚动状态改变回调

 // Note: over-scroll is set-up using the helper method. IOverScrollDecor decor = OverScrollDecoratorHelper.setUpOverScroll(recyclerView, OverScrollDecoratorHelper.ORIENTATION_HORIZONTAL);  decor.setOverScrollStateListener(new IOverScrollStateListener() {   @Override   public void onOverScrollStateChange(IOverScrollDecor decor, int oldState, int newState) {     switch (newState) {       case STATE_IDLE:         // No over-scroll is in effect.         break;       case STATE_DRAG_START_SIDE:         // Dragging started at the left-end.         break;       case STATE_DRAG_END_SIDE:         // Dragging started at the right-end.         break;       case STATE_BOUNCE_BACK:         if (oldState == STATE_DRAG_START_SIDE) {           // Dragging stopped -- view is starting to bounce back from the *left-end* onto natural position.         } else { // i.e. (oldState == STATE_DRAG_END_SIDE)           // View is starting to bounce back from the *right-end*.         }         break;     }   } }

拖拽出View原本范围时回调

当前拖拽的强度(偏移量)

 // Note: over-scroll is set-up by explicity instantiating a decorator rather than using the helper; The two methods can be used interchangeably for registering listeners. VerticalOverScrollBounceEffectDecorator decor = new VerticalOverScrollBounceEffectDecorator(new RecyclerViewOverScrollDecorAdapter(recyclerView, itemTouchHelperCallback)); decor.setOverScrollUpdateListener(new IOverScrollUpdateListener() {   @Override   public void onOverScrollUpdate(IOverScrollDecor decor, int state, float offset) {     final View view = decor.getView();     if (offset > 0) {       // 'view' is currently being over-scrolled from the top.     } else if (offset < 0) {       // 'view' is currently being over-scrolled from the bottom.     } else {       // No over-scroll is in-effect.       // This is synonymous with having (state == STATE_IDLE).     }   } });

自定义控件

 public class CustomView extends View {   // ... }  final CustomView view = (CustomView) findViewById(R.id.custom_view); new VerticalOverScrollBounceEffectDecorator(new IOverScrollDecoratorAdapter() {    @Override   public View getView() {     return view;   }    @Override   public boolean isInAbsoluteStart() {     // canScrollUp() is an example of a method you must implement     return !view.canScrollUp();   }    @Override   public boolean isInAbsoluteEnd() {      // canScrollDown() is an example of a method you must implement     return !view.canScrollDown();   } });

拖拽强度和回弹效果配置

 /// Make over-scroll applied over a list-view feel more 'stiff' new VerticalOverScrollBounceEffectDecorator(new AbsListViewOverScrollDecorAdapter(view),     5f, // Default is 3     VerticalOverScrollBounceEffectDecorator.DEFAULT_TOUCH_DRAG_MOVE_RATIO_BCK,     VerticalOverScrollBounceEffectDecorator.DEFAULT_DECELERATE_FACTOR);  // Make over-scroll applied over a list-view bounce-back more softly new VerticalOverScrollBounceEffectDecorator(new AbsListViewOverScrollDecorAdapter(view),     VerticalOverScrollBounceEffectDecorator.DEFAULT_TOUCH_DRAG_MOVE_RATIO_FWD,     VerticalOverScrollBounceEffectDecorator.DEFAULT_TOUCH_DRAG_MOVE_RATIO_BCK,     -1f // Default is -2     );

禁用回弹效果和开启回弹效果

 IOverScrollDecor decor = OverScrollDecoratorHelper.setUpOverScroll(view);  // Detach. You are strongly encouraged to only call this when overscroll isn't // in-effect: Either add getCurrentState()==STATE_IDLE as a precondition, // or use a state-change listener. decor.detach(); // Attach. decor.attach();
