在这里，我想打开一个名为View的新活动类.单击生成的通知后一次.我怎样才能做到这一点??一些立即的答复将不胜感激.之前它工作得很好(在添加带有日历的switch语句之前)现在我收到了通知.但在点击通知后

Here i want to open a new activity class called View. Once after click on the generated notification. How can i do that?? Some immediate reply will be appreciated. It worked well earlier(before add switch statements with calendar) Now i`m getting the notification. but not opening the new activity after clicking on the notification

public class AlarmReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Log.v("Message", "Alarm"); String lang = ""; int imageCode = 1; NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE); Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_launcher); long when = System.currentTimeMillis(); Notification notification; AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent notificationIntent = new Intent(context, View.class); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT); SharedPreferences getPrefs = PreferenceManager.getDefaultSharedPreferences(context); boolean enableNotificaiton = getPrefs.getBoolean("notifications", true); String timePeriod = getPrefs.getString("period", "2"); Calendar calA = Calendar.getInstance(); switch(Integer.parseInt(timePeriod)){ case 1: //<item>Every 30 Minutes</item> calA.add(Calendar.MINUTE, 1); alarmManager.set(AlarmManager.RTC_WAKEUP, calA.getTimeInMillis(), contentIntent); break; case 2: //<item>Hourly</item> calA.add(Calendar.MINUTE, 60); alarmManager.set(AlarmManager.RTC_WAKEUP, calA.getTimeInMillis(), contentIntent); break; case 3: //<item>Every 2 Hours</item> calA.add(Calendar.MINUTE, 120); alarmManager.set(AlarmManager.RTC_WAKEUP, calA.getTimeInMillis(), contentIntent); break; case 4: //<item>Every 6 Hours</item> calA.add(Calendar.MINUTE, 60*6); alarmManager.set(AlarmManager.RTC_WAKEUP, calA.getTimeInMillis(), contentIntent); break; case 5: //<item>Daily</item> calA.add(Calendar.MINUTE, 60*24); alarmManager.set(AlarmManager.RTC_WAKEUP, calA.getTimeInMillis(), contentIntent); break; } String language = getPrefs.getString("language","1"); switch (Integer.parseInt(language)) { case 1: lang = "en"; break; case 2: lang = "sin"; break; } RemoteViews contentView = null; if (lang.equals("en")) { notification = new Notification(R.drawable.ic_launcher, "ProWeather - English", when); contentView = new RemoteViews(context.getPackageName(), R.layout.view); //contentView.setTextViewText(R.id.title, "English Notification"); } else { notification = new Notification(R.drawable.ic_launcher, "ProWeather - Sinhala", when); contentView = new RemoteViews(context.getPackageName(), R.layout.view); switch (imageCode) { case 1: Bitmap bitmap2 = BitmapFactory.decodeResource(context.getResources(), R.drawable.sinhala); contentView.setImageViewBitmap(R.id.ivText, bitmap2); contentView.setTextViewText(R.id.tvDescrition, "Clear Weather"); break; case 2: Bitmap bitmap3 = BitmapFactory.decodeResource(context.getResources(), R.drawable.sinhala2); contentView.setImageViewBitmap(R.id.ivText, bitmap3); contentView.setTextViewText(R.id.tvDescrition, "Heavy Rain"); break; case 3: Bitmap bitmap4 = BitmapFactory.decodeResource(context.getResources(), R.drawable.sinhala3); contentView.setImageViewBitmap(R.id.ivText, bitmap4); contentView.setTextViewText(R.id.tvDescrition, "Heavy Rain with Lightning"); break; } } notification.contentView = contentView; notification.flags = Notification.FLAG_AUTO_CANCEL; notification.contentIntent = contentIntent; // Cancel the notification after its selected notification.flags |= Notification.FLAG_AUTO_CANCEL; notification.defaults |= Notification.DEFAULT_LIGHTS; // LED notification.defaults |= Notification.DEFAULT_VIBRATE; // Vibration notification.defaults |= Notification.DEFAULT_SOUND; // Sound // setting id a constant will replace previous notification with the // new notificationManager.notify(100, notification); } }

推荐答案

使用以下代码:

int icon = R.drawable.app_notification_icon; long when = System.currentTimeMillis(); NotificationManager notificationManager = (NotificationManager) context .getSystemService(Context.NOTIFICATION_SERVICE); Notification notification = new Notification(icon, message, when); String title = context.getString(R.string.app_name); Intent notificationIntent = new Intent(context, NotificationDialog.class); // set intent so it does not start a new activity notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); notificationIntent.putExtra(IntentConstantsUtils.MESSAGE, message); PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT); notification.setLatestEventInfo(context, title, message, intent); notification.flags |= Notification.FLAG_AUTO_CANCEL; // Play default notification sound notification.defaults |= Notification.DEFAULT_SOUND; // Vibrate if vibrate is enabled notification.defaults |= Notification.DEFAULT_VIBRATE; notificationManager.notify(0, notification);

创建一个新的Java类:

Create a new java class:

public class NotificationDialog extends Activity{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); String message = getIntent().getStringExtra(IntentConstantsUtils.MESSAGE); showDialog(this, message, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { finish(); } }); } private void showDialog(Context context, String message, DialogInterface.OnClickListener onOkClick) { AlertDialog alertDialog = new AlertDialog.Builder(context).create(); // Setting Dialog Title alertDialog.setTitle("Alert"); // Setting Dialog Message alertDialog.setMessage(message); // Setting Icon to Dialog // alertDialog.setIcon(R.drawable.tick); // Setting OK Button alertDialog.setButton("OK", onOkClick); // Showing Alert Message alertDialog.show(); } }

在清单中添加

<activity android:name="com.shufflecloud.smg.activities.NotificationDialog" android:screenOrientation="portrait" android:theme="@android:style/Theme.Dialog" > </activity>
