メソッドの詳細

onRestoreInstanceState

public void onRestoreInstanceState(android.os.Parcelable state)

onSaveInstanceState

public android.os.Parcelable onSaveInstanceState()

onScrollChanged

protected void onScrollChanged(int l,
                   int t,
                   int oldl,
                   int oldt)

onInterceptTouchEvent

public boolean onInterceptTouchEvent(android.view.MotionEvent ev)

onTouchEvent

public boolean onTouchEvent(android.view.MotionEvent ev)

setScrollViewCallbacks

public void setScrollViewCallbacks(ObservableScrollViewCallbacks listener)

インタフェースからコピーされた説明: Scrollable

Sets a callback listener.

定義:

setScrollViewCallbacks インタフェース内 Scrollable

パラメータ:

listener - listener to set

setTouchInterceptionViewGroup

public void setTouchInterceptionViewGroup(android.view.ViewGroup viewGroup)

インタフェースからコピーされた説明: Scrollable

Sets a touch motion event delegation ViewGroup. This is used to pass motion events back to parent view. It's up to the implementation classes whether or not it works.

定義:

setTouchInterceptionViewGroup インタフェース内 Scrollable

パラメータ:

viewGroup - ViewGroup object to dispatch motion events

scrollVerticallyTo

public void scrollVerticallyTo(int y)

インタフェースからコピーされた説明: Scrollable

Scrolls vertically to the absolute Y. Implemented classes are expected to scroll to the exact Y pixels from the top, but it depends on the type of the widget.

定義:

scrollVerticallyTo インタフェース内 Scrollable

パラメータ:

y - vertical position to scroll to

scrollVerticallyToPosition

public void scrollVerticallyToPosition(int position)

Same as #scrollToPosition(int) but it scrolls to the position not only make the position visible.

It depends on LayoutManager how #scrollToPosition(int) works, and currently we know that LinearLayoutManager#scrollToPosition(int) just make the position visible.

In LinearLayoutManager, scrollToPositionWithOffset() is provided for scrolling to the position. This method checks which LayoutManager is set, and handles which method should be called for scrolling.

Other know classes (StaggeredGridLayoutManager and GridLayoutManager) are not tested.

パラメータ:

position - position to scroll

getCurrentScrollY

public int getCurrentScrollY()

インタフェースからコピーされた説明: Scrollable

Returns the current Y of the scrollable view.

定義:

getCurrentScrollY インタフェース内 Scrollable

戻り値:

current Y pixel

getChildAdapterPosition

public int getChildAdapterPosition(android.view.View child)
