InCallMenuItemView

public class InCallMenuItemView extends android.widget.TextView
The View for each item in the {@link InCallMenuView}. Each in-call menu item has a text label, an optional "green LED" on/off indicator below the text, and an optional icon above the text. (It's really just a TextView, using "compound drawables" for the indicator and icon.) Originally modeled after android/widget/IconMenuItemView.java.

private voidupdateCompoundDrawables()
Installs mIcon and mIndicatorDrawable as our TextView "compound drawables", and does any necessary layout tweaking depending on the presence or absence of the icon or indicator.

        // TODO: There are several hand-tweaked layout constants hardcoded here.
        // If we ever move this widget into the framework (and make it
        // usable from XML), be sure to move these constants to XML too.

        // If the icon is visible, add a bit of negative padding to scoot
        // it down closer to the text.
        if (mIcon != null) {
            setCompoundDrawablePadding(-10);
        }

        // Add some top/bottom padding when the indicator and/or icon are
        // visible (to add a little vertical space between the indicator
        // and the bottom of the item, or the icon and the top of the
        // item.)
        int topPadding = (mIcon != null) ? 5 : 0;
        int bottomPadding = (mIndicatorDrawable != null) ? 5 : 0;
        setPadding(0, topPadding, 0, bottomPadding);

        // TODO: topPadding seems to have no effect here.
        // Regardless of the value I use, the icon image
        // ends up right up against the top edge of the button...
        // (Maybe we're just out of room?)
        // if (DBG) log("updateCompoundDrawables: padding: top " + topPadding
        //              + ", bottom " + bottomPadding);

        setCompoundDrawablesWithIntrinsicBounds(null, mIcon, null, mIndicatorDrawable);
private voidupdateIndicator()
Updates mIndicatorDrawable based on mIndicatorVisible and mIndicatorState.

        if (mIndicatorVisible) {
            int resId = mIndicatorState ? android.R.drawable.button_onoff_indicator_on
                    : android.R.drawable.button_onoff_indicator_off;
            mIndicatorDrawable = getResources().getDrawable(resId);
        } else {
            mIndicatorDrawable = null;
        }
