Usage

From source file:android.support.v7.widget.TooltipCompatHandler.java

/**
 * Set the tooltip text for the view.// w w w.j av a2 s  . c  o  m
 *
 * @param view        view to set the tooltip on
 * @param tooltipText the tooltip text
 */
public static void setTooltipText(View view, CharSequence tooltipText) {
    // The code below is not attempting to update the tooltip text
    // for a pending or currently active tooltip, because it may lead
    // to updating the wrong tooltipin in some rare cases (e.g. when
    // action menu item views are recycled). Instead, the tooltip is
    // canceled/hidden. This might still be the wrong tooltip,
    // but hiding wrong tooltip is less disruptive UX.
    if (sPendingHandler != null && sPendingHandler.mAnchor == view) {
        setPendingHandler(null);
    }
    if (TextUtils.isEmpty(tooltipText)) {
        if (sActiveHandler != null && sActiveHandler.mAnchor == view) {
            sActiveHandler.hide();
        }
        view.setOnLongClickListener(null);

        view.setOnHoverListener(null);
    } else {
