android - 使用slidingmenu(jfeinstein10)，如何知道是否显示了slidingmenu(有些方法不生效)

Question

使用slidingmenu(jfeinstein10)，如何知道是否显示了slidingmenu(有些方法不生效)。我想知道滑动菜单的状态，我已经试过了:

        Log.d("slidingMenu.isShown()", slidingMenu.isShown()+"");
        Log.d("slidingMenu.isShown()", slidingMenu.getVisibility()+"");
        Log.d("slidingMenu.isShown()", slidingMenu.isActivated()+"");
        Log.d("slidingMenu.hasFocus()", slidingMenu.hasFocus()+"");
        Log.d("slidingMenu.hasFocusable()", slidingMenu.hasFocusable()+"");
        Log.d("slidingMenu.hasWindowFocus()", slidingMenu.hasWindowFocus()+"");
        Log.d("slidingMenu.isActivated()", slidingMenu.isActivated()+"");
        Log.d("slidingMenu.isClickable()", slidingMenu.isClickable()+"");
        Log.d("slidingMenu.isEnabled();", slidingMenu.isEnabled()+"");
        Log.d("slidingMenu.isFocusable()", slidingMenu.isFocusable()+"");
        Log.d("slidingMenu.isFocused()", slidingMenu.isFocused()+"");
        Log.d("slidingMenu.isSlidingEnabled()", slidingMenu.isSlidingEnabled()+"");
        Log.d("slidingMenu.isSelected()", slidingMenu.isSelected()+"");

但是无论menufragment是显示还是消失，这些方法返回相同的值。

Line 550 in SlidingMenu.java :

/**
 * Checks if is the behind view showing.
 *
 * @return Whether or not the behind view is showing
 */
public boolean isMenuShowing() {
    return mViewAbove.getCurrentItem() == 0 || mViewAbove.getCurrentItem() == 2;
}
