我已经创建了一个管理短信的应用程序,我已经创建了通知,但是当我点击它们时它启动了另一个活动,我想知道如何检查一个活动是否已经停止并恢复它.

以下是用于创建pendingintent的代码:

private void createNotification(SmsMessage sms, Context context){

    final NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

    String contentTitle = "";


    // construct the Notification object.
        final NotificationCompat.Builder  builder = new NotificationCompat.Builder(context)
        .setContentTitle(contentTitle)
         .setContentText(sms.getMessageBody())
         .setSmallIcon(R.drawable.ic_launcher)
         .setLargeIcon(getIconBitmap())
         .setNumber(nmessages);

        builder.setAutoCancel(true);

        //(R.drawable.stat_sample, tickerText,
          //      System.currentTimeMillis());

        // Set the info for the views that show in the notification panel.
        //notif.setLatestEventInfo(this, from, message, contentIntent);
        /*
        // On tablets, the ticker shows the sender, the first line of the message,
        // the photo of the person and the app icon. …

我有一个带开关的布局.我希望文本在左侧,实际的开关在右侧.我该怎么做？我知道这是可能的,因为它们在手机设置中就是这样.

现在的情况:

我有一个wip Framework项目,我在其中派生了Fragment类创建了OnlineFragment.在我当前的应用程序项目中,我创建了Account类,它继承了OnlineFragment而没有任何问题,但是当我尝试在主活动中实例化Fragment frag = new Account();

我收到此错误:

类型不匹配:无法从帐户转换为片段

这里是类定义

project:com.x.framework

public class OnlineFragment extends Fragment {

project:com.x.app

public class Account extends OnlineFragment {
