java 绘制图形 示例代码

1、简介我们时常看到Android的一些菜单的设置 可以左右滑动,如下图。要实现下面的效果我们可以获得许多的实现在github 通过 收索 “SlidingMenu”。本实验是在http://www.github.com/TangKe/SlideMenu基础上该的。     本次实验的实验的效果 2、具体的实现。 本次实验的基础是在上面提供的资源和code，应用到我们实验上面。（1）、BaseSlideMenu public class BaseSlideMenu extends FragmentActivity{private SlideMenu slideMenu;@Overrideprotected void onCreate(Bundle arg0) { // TODO Auto-generated method stub super.onCreate(arg0); setContentView(R.layout.layout_slidemenu);}@Override public void onContentChanged() { // TODO Auto-generated method stub super.onContentChanged(); slideMenu=(SlideMenu) findViewById(R.id.slideMenu); }public void setSlideRole(int res){ if (null==slideMenu) { return; } getLayoutInflater().inflate(res, slideMenu,true);}public SlideMenu getSlideMenu(){ return slideMenu;}} （2）、MainActivity public class MainActivity extends BaseSlideMenu {@Overridepublic void onContentChanged() { // TODO Auto-generated method stub super.onContentChanged(); System.out.println(">>>>"); setSlideRole(R.layout.activity_main); setSlideRole(R.layout.layout_primary_menu); setSlideRole(R.layout.layout_secondary_menu);} }（3）activity_main 注意：  在MainActivity中的三个布局都要 在根结点上面都要有  主界面  slidemenudemo:layout_role="content"   左菜单 slidemenudemo:layout_role="primaryMenu"  右菜单 slidemenudemo:layout_role="secondaryMenu"注意：super.onContentChanged(); 一定要覆盖...
