| Methods Summary |
|---|

View root = LayoutInflater.from(parent.getContext()).inflate(
R.layout.lb_vertical_grid, parent, false);
return new ViewHolder((VerticalGridView) root.findViewById(R.id.browse_grid));
|
| public final void | enableChildRoundedCorners(boolean enable)Enables or disabled rounded corners on children of this row.

|
| protected void | initializeGridViewHolder(android.support.v17.leanback.widget.VerticalGridPresenter$ViewHolder vh)Called after a {@link VerticalGridPresenter.ViewHolder} is created.
Subclasses may override this method and start by calling
super.initializeGridViewHolder(ViewHolder).
if (mNumColumns == -1) {

| public boolean | isUsingDefaultShadow()Returns true if opticalBounds is supported (SDK >= 18) so that default shadow
is applied to each individual child of {@link VerticalGridView}.
Subclass may return false to disable.
return ShadowOverlayContainer.supportsShadow();
|
| public boolean | isUsingZOrder()Returns true if SDK >= L, where Z shadow is enabled so that Z order is enabled
on each child of vertical grid. If subclass returns false in isUsingDefaultShadow()
and does not use Z-shadow on SDK >= L, it should override isUsingZOrder() return false.
return ShadowHelper.getInstance().usesZShadow();

| final boolean | needsDefaultShadow()
return isUsingDefaultShadow() && getShadowEnabled();

| public void | onBindViewHolder(Presenter.ViewHolder viewHolder, java.lang.Object item)
if (DEBUG) Log.v(TAG, "onBindViewHolder " + item);
ViewHolder vh = (ViewHolder) viewHolder;

| public void | setNumberOfColumns(int numColumns)Sets the number of columns in the vertical grid.
if (numColumns < 0) {
throw new IllegalArgumentException("Invalid number of columns");
}

}
|
| public final void | setOnItemClickedListener(OnItemClickedListener listener)Sets the item clicked listener.
OnItemClickedListener will override {@link View.OnClickListener} that
item presenter sets during {@link Presenter#onCreateViewHolder(ViewGroup)}.
So in general, developer should choose one of the listeners but not both.
mOnItemClickedListener = listener;
|
| public final void | setOnItemSelectedListener(OnItemSelectedListener listener)Sets the item selected listener.
Since this is a grid the row parameter is always null.
mOnItemSelectedListener = listener;
|
| public final void | setOnItemViewClickedListener(OnItemViewClickedListener listener)Sets the item clicked listener.
OnItemViewClickedListener will override {@link View.OnClickListener} that
item presenter sets during {@link Presenter#onCreateViewHolder(ViewGroup)}.
So in general, developer should choose one of the listeners but not both.
mOnItemViewClickedListener = listener;
|
| public final void | setOnItemViewSelectedListener(OnItemViewSelectedListener listener)Sets the item selected listener.
Since this is a grid the row parameter is always null.
mOnItemViewSelectedListener = listener;
|
| public final void | setShadowEnabled(boolean enabled)Enable or disable child shadow.
This is not only for enable/disable default shadow implementation but also subclass must
respect this flag.
mShadowEnabled = enabled;
