本文将带你了解Android应用开发之Android Activity栈管理 制定关闭某一个Activity,关闭所有Activit，希望本文对大家学Android有所帮助。
系统Api :打开新的Activity 关闭之前所有Activity。
Intent intent = new Intent(this, LoginActivity.class);intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);startActivity(intent);
自己管理: 将Activity放入集合进行管理
/** * Activity管理类 **/public class AppManager { private static Stack 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(); } 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 activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); activityManager.restartPackage(context.getPackageName()); System.exit(0); } catch (Exception e) { e.printStackTrace(); } } }
