activity管理类 appManager
程序启动第一个界面类: net.oschina.app.AppStart
功能描述:一张图片
代码细节描述:一个透明度的动画效果,效果动画完成后自动启动新的Activity(Main)
基本BaseActivity类,继承自Activity
功能描述:分别在onCreate方法中添加Activity到栈 ; 在onDestroy方法中移除Activity
代码细节描述: 提供了一个单例类AppManager,把创建的Activity放入到栈中进行管理,提供添加Activity , 移除当前Activity , 移除指定的Activity , 移除所有的Activity ,获得当前的Activity , 退出程序。 这个工具类非常适合与用作开发使用,具体代码如下:
import java.util.Stack; import android.app.Activity; import android.app.ActivityManager; import android.content.Context; /** * 应用程序Activity管理类:用于Activity管理和应用程序退出 * @author liux (http://my.oschina.net/liux) * @version 1.0 * @created 2012-3-21 */ public class AppManager { private static Stack<Activity> activityStack; private static AppManager instance; private AppManager(){} /** * 单一实例 */ public static AppManager getAppManager(){ if(instance==null){ instance=new AppManager(); } return instance; } /** * 添加Activity到堆栈 */ public void addActivity(Activity activity){ if(activityStack==null){ activityStack=new Stack<Activity>(); } activityStack.add(activity); } /** * 获取当前Activity(堆栈中最后一个压入的) */ public Activity currentActivity(){ Activity activity=activityStack.lastElement(); return activity; } /** * 结束当前Activity(堆栈中最后一个压入的) */ public void finishActivity(){ Activity activity=activityStack.lastElement(); finishActivity(activity); } /** * 结束指定的Activity */ public void finishActivity(Activity activity){ if(activity!=null){ activityStack.remove(activity); activity.finish(); activity=null; } } /** * 结束指定类名的Activity */ public void finishActivity(Class<?> cls){ for (Activity activity : activityStack) { if(activity.getClass().equals(cls) ){ finishActivity(activity); } } } /** * 结束所有Activity */ public void finishAllActivity(){ for (int i = 0, size = activityStack.size(); i < size; i++){ if (null != activityStack.get(i)){ activityStack.get(i).finish(); } } activityStack.clear(); } /** * 退出应用程序 */ @SuppressWarnings("deprecation") public void AppExit(Context context) { try { finishAllActivity(); ActivityManager activityMgr= (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); activityMgr.restartPackage(context.getPackageName()); System.exit(0); } catch (Exception e) { } } }
仿Activity管理写的Fragment管理
/** * @author lee0000 * @version 1 * @time 10月7日 * */ public class FraManager { private static Stack<Fragment> fragmentStack; private static FraManager instance; private static final Object obj = new Object(); private FraManager() { } /** * 单一实例 */ public static FraManager getFraManager() { if (instance == null) { synchronized (obj) { if (instance == null) { instance = new FraManager(); } } } return instance; } /** * 添加Fragment到堆栈 */ public static void pushFragment(FragmentActivity fact, Fragment fragment, int layoutID, String... title){ if(fragmentStack==null){ fragmentStack=new Stack<Fragment>(); } fragmentStack.push(fragment); FragmentTransaction ft = fact.getSupportFragmentManager().beginTransaction(); ft.replace(layoutID, fragment); if (fragmentStack.size() > 1) { ft.addToBackStack(null); } ft.commit(); } /** * 弹出Fragment */ public static Fragment popFragment(FragmentActivity fact) { Fragment fragment = fragmentStack.pop(); FragmentTransaction ft = fact.getSupportFragmentManager().beginTransaction(); ft.remove(fragment); ft.commit(); return fragment; } /*** * 弹出指定Activity中所有的fragment * */ public static void finishFragment(FragmentActivity fact){ for (int i = 0, size = fragmentStack.size(); i < size; i++){ Fragment stackFragment = fragmentStack.get(i); if (null != stackFragment){ Fragment fragment = stackFragment; if (fact == fragment.getActivity()) { FragmentTransaction ft = fragment.getFragmentManager().beginTransaction(); ft.remove(fragment); fragmentStack.remove(i); ft.commit(); } } } } /** * 清除栈中所有的项 * */ public static void clearStack(){ if (fragmentStack != null && fragmentStack.isEmpty()) { fragmentStack.clear(); } } }
