*** ** * ** *** An abstract [Presenter](https://developer.android.com/reference/android/support/v17/leanback/widget/Presenter) that renders an Object in RowsFragment, the object can be subclass [Row](https://developer.android.com/reference/android/support/v17/leanback/widget/Row) or a generic one. When the object is not [Row](https://developer.android.com/reference/android/support/v17/leanback/widget/Row) class, [getRow()](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter.ViewHolder#getRow()) returns null. ### Customize UI widgets When a subclass of RowPresenter adds UI widgets, it should subclass [RowPresenter.ViewHolder](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter.ViewHolder) and override [createRowViewHolder(ViewGroup)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#createRowViewHolder(android.view.ViewGroup)) and [initializeRowViewHolder(ViewHolder)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#initializeRowViewHolder(android.support.v17.leanback.widget.RowPresenter.ViewHolder)). The subclass must use layout id "row_content" for the widget that will be aligned to the title of any [HeadersFragment](https://developer.android.com/reference/android/support/v17/leanback/app/HeadersFragment) that may exist in the parent fragment. RowPresenter contains an optional and replaceable [RowHeaderPresenter](https://developer.android.com/reference/android/support/v17/leanback/widget/RowHeaderPresenter) that renders the header. You can disable the default rendering or replace the Presenter with a new header presenter by calling [setHeaderPresenter(RowHeaderPresenter)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#setHeaderPresenter(android.support.v17.leanback.widget.RowHeaderPresenter)). ### UI events from fragments RowPresenter receives calls from its parent (typically a Fragment) when: - A row is selected via [setRowViewSelected(Presenter.ViewHolder, boolean)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#setRowViewSelected(android.support.v17.leanback.widget.Presenter.ViewHolder, boolean)). The event is triggered immediately when there is a row selection change before the selection animation is started. Selected status may control activated status of the row (see "Activated status" below). Subclasses of RowPresenter may override [onRowViewSelected(ViewHolder, boolean)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#onRowViewSelected(android.support.v17.leanback.widget.RowPresenter.ViewHolder, boolean)). - A row is expanded to full height via [setRowViewExpanded(Presenter.ViewHolder, boolean)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#setRowViewExpanded(android.support.v17.leanback.widget.Presenter.ViewHolder, boolean)) when BrowseFragment hides fast lane on the left. The event is triggered immediately before the expand animation is started. Row title is shown when row is expanded. Expanded status may control activated status of the row (see "Activated status" below). Subclasses of RowPresenter may override [onRowViewExpanded(ViewHolder, boolean)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#onRowViewExpanded(android.support.v17.leanback.widget.RowPresenter.ViewHolder, boolean)). ### Activated status The activated status of a row is applied to the row view and its children via [setActivated(boolean)](https://developer.android.com/reference/android/view/View.html#setActivated(boolean)). The activated status is typically used to control [BaseCardView](https://developer.android.com/reference/android/support/v17/leanback/widget/BaseCardView) info region visibility. The row's activated status can be controlled by selected status and/or expanded status. Call [setSyncActivatePolicy(int)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#setSyncActivatePolicy(int)) and choose one of the four policies: - [SYNC_ACTIVATED_TO_EXPANDED](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#SYNC_ACTIVATED_TO_EXPANDED) Activated status is synced with row expanded status - [SYNC_ACTIVATED_TO_SELECTED](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#SYNC_ACTIVATED_TO_SELECTED) Activated status is synced with row selected status - [SYNC_ACTIVATED_TO_EXPANDED_AND_SELECTED](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#SYNC_ACTIVATED_TO_EXPANDED_AND_SELECTED) Activated status is set to true when both expanded and selected status are true - [SYNC_ACTIVATED_CUSTOM](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#SYNC_ACTIVATED_CUSTOM) Activated status is not controlled by selected status or expanded status, application can control activated status by its own. Application should call [setActivated(boolean)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter.ViewHolder#setActivated(boolean)) to change activated status of row view. ### User events RowPresenter provides [OnItemViewSelectedListener](https://developer.android.com/reference/android/support/v17/leanback/widget/OnItemViewSelectedListener) and [OnItemViewClickedListener](https://developer.android.com/reference/android/support/v17/leanback/widget/OnItemViewClickedListener). If a subclass wants to add its own [View.OnFocusChangeListener](https://developer.android.com/reference/android/view/View.OnFocusChangeListener.html) or [View.OnClickListener](https://developer.android.com/reference/android/view/View.OnClickListener.html), it must do that in [createRowViewHolder(ViewGroup)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#createRowViewHolder(android.view.ViewGroup)) to be properly chained by the library. Adding View listeners after [createRowViewHolder(ViewGroup)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#createRowViewHolder(android.view.ViewGroup)) is undefined and may result in incorrect behavior by the library's listeners. ### Selection animation When a user scrolls through rows, a fragment will initiate animation and call [setSelectLevel(Presenter.ViewHolder, float)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#setSelectLevel(android.support.v17.leanback.widget.Presenter.ViewHolder, float)) with float value between 0 and 1. By default, the RowPresenter draws a dim overlay on top of the row view for views that are not selected. Subclasses may override this default effect by having [isUsingDefaultSelectEffect()](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#isUsingDefaultSelectEffect()) return false and overriding [onSelectLevelChanged(ViewHolder)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#onSelectLevelChanged(android.support.v17.leanback.widget.RowPresenter.ViewHolder)) to apply a different selection effect. Call [setSelectEffectEnabled(boolean)](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter#setSelectEffectEnabled(boolean)) to enable/disable the select effect, This will not only enable/disable the default dim effect but also subclasses must respect this flag as well.
