Methods Summary
public android.support.v7.media.MediaRouteSelectorgetRouteSelector()
Gets the media route selector for filtering the routes that the user can select.

return

public voidonAttachedToWindow()

        super.onAttachedToWindow();

        mAttachedToWindow = true;
        mRouter.addCallback(mSelector, mCallback, MediaRouter.CALLBACK_FLAG_PERFORM_ACTIVE_SCAN);
        refreshRoutes();
protected voidonCreate(android.os.Bundle savedInstanceState)

        super.onCreate(savedInstanceState);

        getWindow().requestFeature(Window.FEATURE_LEFT_ICON);

        setContentView(R.layout.mr_media_route_chooser_dialog);
        setTitle(R.string.mr_media_route_chooser_title);

        // Must be called after setContentView.
        getWindow().setFeatureDrawableResource(Window.FEATURE_LEFT_ICON,
                MediaRouterThemeHelper.getThemeResource(
                        getContext(), R.attr.mediaRouteOffDrawable));

        mRoutes = new ArrayList<MediaRouter.RouteInfo>();
        mAdapter = new RouteAdapter(getContext(), mRoutes);

        mListView.setOnItemClickListener(mAdapter);
        mListView.setEmptyView(findViewById(android.R.id.empty));
public voidonDetachedFromWindow()

        mAttachedToWindow = false;
        mRouter.removeCallback(mCallback);

        super.onDetachedFromWindow();
public booleanonFilterRoute(MediaRouter.RouteInfo route)
Returns true if the route should be included in the list.

The default implementation returns true for enabled non-default routes that match the selector. Subclasses can override this method to filter routes differently.

param
route The route to consider, never null.
return
True if the route should be included in the chooser dialog.

        return !route.isDefault() && route.isEnabled() && route.matchesSelector(mSelector);
public voidonFilterRoutes(java.util.List routes)
Called to filter the set of routes that should be included in the list.

The default implementation iterates over all routes in the provided list and removes those for which {@link #onFilterRoute} returns false.

param
routes The list of routes to filter in-place, never null.

        for (int i = routes.size(); i-- > 0; ) {
            if (!onFilterRoute(routes.get(i))) {
                routes.remove(i);
            }
        }
public voidrefreshRoutes()
Refreshes the list of routes that are shown in the chooser dialog.

        if (mAttachedToWindow) {
            mRoutes.clear();
            mRoutes.addAll(mRouter.getRoutes());
            onFilterRoutes(mRoutes);
            Collections.sort(mRoutes, RouteComparator.sInstance);
            mAdapter.notifyDataSetChanged();
        }
public voidsetRouteSelector(android.support.v7.media.MediaRouteSelector selector)
Sets the media route selector for filtering the routes that the user can select.

param
selector The selector, must not be null.

        if (selector == null) {
            throw new IllegalArgumentException("selector must not be null");
        }

        if (!mSelector.equals(selector)) {
            mSelector = selector;

            if (mAttachedToWindow) {
                mRouter.removeCallback(mCallback);
                mRouter.addCallback(selector, mCallback,
                        MediaRouter.CALLBACK_FLAG_PERFORM_ACTIVE_SCAN);
            }

            refreshRoutes();
        }
