在前一篇文章自定义菜单样式中有提到怎样自定义菜单，那个方法在2.3版本之前好像都可以，2.3开始就不起作用了。具体原因不知道，可能是android对LayoutInflater.Factory进行了限制

2.3之后要实现自定义的菜单，只能自己实现了，下面是我参考别人的代码写的，出处忘了。

public class DancerMenu  {private LinearLayout mLayout = null;private Context mContext = null;private Activity mActivity = null;private Animation mShowAnimation = null;private Animation mHideAnimation = null;private Resources res;private LinearLayout mWeather, mWallpaper, mNotification, mTask, mWidget;public DancerMenu(Context context,View view){mContext = context;mLayout = (LinearLayout)(view.findViewById(R.id.layout_custom_menu));...}private class MenuOnClickListener implements OnClickListener{public void onClick(View v) {switch(v.getId()){...break;default:break;}}}public void CreateMenu() {if (mLayout.getVisibility() == View.GONE)showAppMenu();else hideAppMenu();}private void showAppMenu(){if(mShowAnimation == null){mShowAnimation = AnimationUtils.loadAnimation(mContext, R.anim.menushow);}mLayout.startAnimation(mShowAnimation);mLayout.requestFocus();mLayout.setVisibility(View.VISIBLE);}public void hideAppMenu(){if(mHideAnimation == null)mHideAnimation = AnimationUtils.loadAnimation(mContext, R.anim.menuhide);mLayout.startAnimation(mHideAnimation);mLayout.setVisibility(View.GONE);}public boolean isShow(){if(mLayout.getVisibility() == View.VISIBLE)return true;return false;}}

菜单呼出和隐藏的动画：

menuhide.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android">    <translate     android:fromXDelta="0"    android:toXDelta="0"    android:fromYDelta="0"    android:toYDelta="140"    android:duration="500"    android:fillAfter="true"    android:fillEnabled="true"    /></set>

menushow.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android">    <translate     android:fromXDelta="0"    android:toXDelta="0"    android:fromYDelta="140"    android:toYDelta="0"    android:duration="500"    android:fillAfter="true"    android:fillEnabled="true"    /></set>
