Class PlayerControlView

  • All Implemented Interfaces:
    Drawable.Callback, AccessibilityEventSource, KeyEvent.Callback, ViewManager, ViewParent
    public class PlayerControlView
extends FrameLayout
    A view for controlling Player instances.

    A PlayerControlView can be customized by setting attributes (or calling corresponding methods), overriding drawables, overriding the view's layout file, or by specifying a custom view layout file.

    Attributes

    The following attributes can be set on a PlayerControlView when used in a layout XML file:
    • show_timeout - The time between the last user interaction and the controls being automatically hidden, in milliseconds. Use zero if the controls should not automatically timeout.
    • show_rewind_button - Whether the rewind button is shown.
    • show_fastforward_button - Whether the fast forward button is shown.
    • show_previous_button - Whether the previous button is shown.
    • show_next_button - Whether the next button is shown.
    • repeat_toggle_modes - A flagged enumeration value specifying which repeat mode toggle options are enabled. Valid values are: none, one, all, or one|all.
    • show_shuffle_button - Whether the shuffle button is shown.
    • time_bar_min_update_interval - Specifies the minimum interval between time bar position updates.
    • controller_layout_id - Specifies the id of the layout to be inflated. See below for more details.
      • Corresponding method: None
      • Default: R.layout.exo_player_control_view
    • All attributes that can be set on DefaultTimeBar can also be set on a PlayerControlView, and will be propagated to the inflated DefaultTimeBar unless the layout is overridden to specify a custom exo_progress (see below).

    Overriding drawables

    The drawables used by PlayerControlView (with its default layout file) can be overridden by drawables with the same names defined in your application. The drawables that can be overridden are:
    • exo_controls_play - The play icon.
    • exo_controls_pause - The pause icon.
    • exo_controls_rewind - The rewind icon.
    • exo_controls_fastforward - The fast forward icon.
    • exo_controls_previous - The previous icon.
    • exo_controls_next - The next icon.
    • exo_controls_repeat_off - The repeat icon for Player.REPEAT_MODE_OFF.
    • exo_controls_repeat_one - The repeat icon for Player.REPEAT_MODE_ONE.
    • exo_controls_repeat_all - The repeat icon for Player.REPEAT_MODE_ALL.
    • exo_controls_shuffle_off - The shuffle icon when shuffling is disabled.
    • exo_controls_shuffle_on - The shuffle icon when shuffling is enabled.
    • exo_controls_vr - The VR icon.

    Overriding the layout file

    To customize the layout of PlayerControlView throughout your app, or just for certain configurations, you can define exo_player_control_view.xml layout files in your application res/layout* directories. These layouts will override the one provided by the library, and will be inflated for use by PlayerControlView. The view identifies and binds its children by looking for the following ids:
    • exo_play - The play button.
    • exo_pause - The pause button.
    • exo_rew - The rewind button.
    • exo_ffwd - The fast forward button.
    • exo_prev - The previous button.
    • exo_next - The next button.
    • exo_repeat_toggle - The repeat toggle button.
      • Type: ImageView
      • Note: PlayerControlView will programmatically set the drawable on the repeat toggle button according to the player's current repeat mode. The drawables used are exo_controls_repeat_off, exo_controls_repeat_one and exo_controls_repeat_all. See the section above for information on overriding these drawables.
    • exo_shuffle - The shuffle button.
      • Type: ImageView
      • Note: PlayerControlView will programmatically set the drawable on the shuffle button according to the player's current repeat mode. The drawables used are exo_controls_shuffle_off and exo_controls_shuffle_on. See the section above for information on overriding these drawables.
    • exo_vr - The VR mode button.
    • exo_position - Text view displaying the current playback position.
    • exo_duration - Text view displaying the current media duration.
    • exo_progress_placeholder - A placeholder that's replaced with the inflated DefaultTimeBar. Ignored if an exo_progress view exists.
    • exo_progress - Time bar that's updated during playback and allows seeking. DefaultTimeBar attributes set on the PlayerControlView will not be automatically propagated through to this instance. If a view exists with this id, any exo_progress_placeholder view will be ignored.

    All child views are optional and so can be omitted if not required, however where defined they must be of the expected type.

    Specifying a custom layout file

    Defining your own exo_player_control_view.xml is useful to customize the layout of PlayerControlView throughout your application. It's also possible to customize the layout for a single instance in a layout file. This is achieved by setting the controller_layout_id attribute on a PlayerControlView. This will cause the specified layout to be inflated instead of exo_player_control_view.xml for only the instance on which the attribute is set.

        public void setTimeBarMinUpdateInterval​(int minUpdateIntervalMs)
        Sets the minimum interval between time bar position updates.

        Note that smaller intervals, e.g. 33ms, will result in a smooth movement but will use more CPU resources while the time bar is visible, whereas larger intervals, e.g. 200ms, will result in a step-wise update with less CPU usage.

        Parameters:
        minUpdateIntervalMs - The minimum interval between time bar position updates, in milliseconds.
