自定义菜单，透明背景

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>
