VideoFragment

VideoFragment This class is deprecated. use VideoSupportFragment

This class is deprecated.
use PlaybackSupportFragment

A fragment for displaying playback controls and related content.

A PlaybackFragment renders the elements of its ObjectAdapter as a set of rows in a vertical list. The Adapter's PresenterSelector must maintain subclasses of RowPresenter.

A playback row is a row rendered by PlaybackRowPresenter. App can call setPlaybackRow(Row) to set playback row for the first element of adapter. App can call setPlaybackRowPresenter(PlaybackRowPresenter) to set presenter for it. setPlaybackRow(Row) and setPlaybackRowPresenter(PlaybackRowPresenter) are optional, app can pass playback row and PlaybackRowPresenter in the adapter using setAdapter(ObjectAdapter).

Hiding and showing controls: the controls are initially visible and automatically show/hide when play/pause or user interacts with fragment.

App may manually call showControlsOverlay(boolean) or hideControlsOverlay(boolean) to show or hide the controls.
The controls are visible by default upon onViewCreated(). To make it initially invisible, call hideControlsOverlay(false) in overridden onViewCreated().

R.attr.playbackControlsAutoHideTimeout

#setControlsOverlayAutoHideEnabled(boolean)

Upon user interaction event, fragment will fade-in the controls and automatically fade out after a delay customized by R.attr.playbackControlsAutoHideTickleTimeout. To disable the fade in and fade out behavior, call setShowOrHideControlsOverlayOnUserInteraction(boolean) with false.

public void setAdapter (ObjectAdapter adapter)

Sets the list of rows for the fragment. A default ClassPresenterSelector will be created if ObjectAdapter.getPresenterSelector() is null. if user provides setPlaybackRow(Row) and setPlaybackRowPresenter(PlaybackRowPresenter), the row and presenter will be set onto the adapter.

Parameters

Parameters
`type`	`int`: One of BG_LIGHT, BG_DARK, or BG_NONE.

setControlsOverlayAutoHideEnabled

public void setControlsOverlayAutoHideEnabled (boolean enabled)

Enables or disables auto hiding controls overlay after a short delay fragment is resumed. If enabled and fragment is resumed, the view will fade out after a time period. User interaction will kill the timer, next time fragment is resumed, the timer will be started again if isControlsOverlayAutoHideEnabled() is true.

In most cases app should not directly call setControlsOverlayAutoHideEnabled() as it's called by PlaybackBaseControlGlue on play or pause.

Parameters
`enabled`	`boolean`

setFadingEnabled

public void setFadingEnabled (boolean enabled)

This method is deprecated.
Uses setControlsOverlayAutoHideEnabled(boolean)

Parameters

public void setHostCallback (PlaybackGlueHost.HostCallback hostCallback)

Sets the PlaybackGlueHost.HostCallback. Implementor of this interface will take appropriate actions to take action when the hosting fragment starts/stops processing.

Parameters
`hostCallback`	`PlaybackGlueHost.HostCallback`

public void setOnItemViewClickedListener (BaseOnItemViewClickedListener listener)

This listener is called every time there is a click in RowsFragment. This can be used by users to take additional actions such as animations.

Parameters
`listener`	`BaseOnItemViewClickedListener`

public void setOnItemViewSelectedListener (BaseOnItemViewSelectedListener listener)

This listener is called every time there is a selection in RowsFragment. This can be used by users to take additional actions such as animations.

Parameters
`listener`	`BaseOnItemViewSelectedListener`

setOnKeyInterceptListener

public final void setOnKeyInterceptListener (View.OnKeyListener handler)

Sets the input event handler.

Parameters
`handler`	`View.OnKeyListener`

public void setOnPlaybackItemViewClickedListener (BaseOnItemViewClickedListener listener)

Sets the BaseOnItemViewClickedListener that would be invoked for clicks only on PlaybackRowPresenter.ViewHolder.

Parameters

Parameters
`row`	`Row`: The row that represents the playback.

public void setPlaybackRowPresenter (PlaybackRowPresenter presenter)

Sets the presenter for rendering the playback row set by setPlaybackRow(Row). If adapter does not set a PresenterSelector, setAdapter(ObjectAdapter) will create a ClassPresenterSelector by default and map from the row object class to this PlaybackRowPresenter.

Parameters
`presenter`	`PlaybackRowPresenter`: Presenter used to render `setPlaybackRow(Row)`.

public void setPlaybackSeekUiClient (PlaybackSeekUi.Client client)

Interface to be implemented by UI widget to support PlaybackSeekUi.

Sets the selected row position.

Parameters
`position`	`int`
`smooth`	`boolean`

setShowOrHideControlsOverlayOnUserInteraction

public void setShowOrHideControlsOverlayOnUserInteraction (boolean showOrHideControlsOverlayOnUserInteraction)

showControlsOverlay

public void showControlsOverlay (boolean runAnimation)

Show controls overlay.

Parameters
`runAnimation`	`boolean`: True to run animation, false otherwise.

tickle

public void tickle ()

Tickles the playback controls. Fades in the view if it was faded out. tickle() will kill and re-create a timer if R.attr.playbackControlsAutoHideTickleTimeout is positive.

In most cases app does not need call tickle() as it's automatically called on user interactions.
