Android开源之——MenuDrawer
现在很多应用都很潇洒的从左边屏幕手势一划出个左边的隐藏菜单，右边一划出个隐藏菜单，上边一划出个隐藏菜单，下边一划出个隐藏菜单。其实都是使用https://github.com/licong/android-menudrawer 来实现的。
现在我们来分析如何在eclipse开发。
1. 将下载好的zip文件解压，然后倒入到eclipse里。但是在导入之前，先把.classespath文件删掉，因为编译环境不同，我们让它再重新生成。
2. 开发自己的工程。
3. 倒入menudrawer库。右击开发的项目，然后选中property->android->IsLibrary不要选中它->Add 选中menudrawer，然后就可以使用了。
现在来分析menudrawer的使用方法。
*************************左边MenuDrawer**********
1.设置主页
menuDrawer=MenuDrawer.attach(this,MenuDrawer.MENU_DRAG_CONTENT);
menuDrawer.setContentView(R.layout.activity_main);
2.设置Menu页/高度
menuDrawer.setMenuView(mListView);
menuDrawer.setMenuSize(getWindowManager().getDefaultDisplay().getWidth());
3.主/Menu页相互跳转
menuDrawer.toggleMenu();
4.关闭Menu页
menuDrawer.closeMenu();
5.右边标示的保存和滑动:
getView(设置Tag): v.setTag(R.id.mdActiveViewPosition, position);
OnItemClickListener(设置当前活跃Item):menuDrawer.setActiveView(v,position);
6.滑动时(刷新指示标示)
mListView.setOnScrollListener(newOnScrollListener() {
@Override
public void onScrollStateChanged(AbsListViewview, int scrollState) {
}
@Override
public void onScroll(AbsListView view, intfirstVisibleItem,
intvisibleItemCount, int totalItemCount) {
menuDrawer.invalidate();
}
});
7.设置拖动有效的区域
menuDrawer.setTouchMode(MenuDrawer.TOUCH_MODE_FULLSCREEN);
8.第4个参数判断能否被拖动
menuDrawer=MenuDrawer.attach(this,MenuDrawer.MENU_DRAG_CONTENT,Position.RIGHT,true);
具体的方法和实例可以参照下载下来的实例分析。
附上自己写的简单代码：
