AppWidget不能打开指定Activity,只能拉起App的问题

今天开发Widget遇到一个小问题

App启动后后台,  AppWidget不能打开指定Activity, 只能拉起App, 相当于从桌面的ICON进入了App

通过增加 如下flag解决之

Intent.FLAG_ACTIVITY_CLEAR_TASK

private static int requestCode &＃61; 0;//如果多次调用getActivity, requestCode 值相同, 会导致Extras是最后一次放进去的值
public static PendingIntent getWidgetPendingIntent(Context context, String page) {final Intent activityIntent &＃61; new Intent(context, StartActivity.class);Bundle bundle &＃61; new Bundle();bundle.putString(FTKEY_WIDGET_TO_PAGE, page);activityIntent.putExtras(bundle);activityIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TASK);final PendingIntent refreshPendingIntent &＃61; PendingIntent.getActivity(context, requestCode&＃43;&＃43;, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);return refreshPendingIntent;
}
