按键的处理思路：

/* 
	 * 监听菜单键,当用户点击菜单键的时候，显示和隐藏一级和二级菜单
	 * 
	 * 监听返回键,再按一次退出程序
	 */
	private long exitTime = 0;
	@Override
	public boolean onKeyDown(int keyCode, KeyEvent event) {
		// 菜单键的处理
		if(event.getAction() == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_MENU){
			// 如果 一级菜单显示,隐藏 全部
			if(isShowLevel1){
				MyAnimationUtils.animaOut(level);
				isShowLevel1 = false;
				if(isShowLevel2){
					MyAnimationUtils.animaOut(level2,120);
					isShowLevel2 = false;
					if(isShowLevel3){
						MyAnimationUtils.animaOut(level3,120);
						isShowLevel3 = false;
					}
				}
			}else{
				// 如果一级菜单式隐藏的,显示 一,二级菜单
				MyAnimationUtils.animaIn(level);
				MyAnimationUtils.animaIn(level2, 120);
				isShowLevel1 = true;
				isShowLevel2 = true;
			}
		}
		// 返回键
		if(event.getAction() == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_BACK){
			if(System.currentTimeMillis() - exitTime > 2000){
				Toast.makeText(this, "再按一次返回键退出", Toast.LENGTH_SHORT).show();
				exitTime = System.currentTimeMillis();
			}else{
				finish();
				System.exit(0);
			}
			return true;
		}
		return super.onKeyDown(keyCode, event);
	}
