[英]Android Notification Action - Intent Extra not working as expected
[英]Android notification not working as expected
我想創建每 3 天出現一次的帶有聲音和振動的通知。 我不能讓它發生
幾乎嘗試了我在互聯網上找到的所有解決方案。 你會從我的代碼中看到它。 使用我的代碼,聲音不起作用,振動不起作用,即使取消通知也會連續顯示更多次,即使我將優先級設置為高,它也不會在鎖定時顯示在屏幕上。 超級奇怪
這是在 MainActivity 中設置通知的函數:
public void setNotification() {
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 10);
calendar.set(Calendar.MINUTE, 45);
Intent myIntent = new Intent(this, NotifyService.class);
int ALARM1_ID = 10000;
PendingIntent pendingIntent = PendingIntent.getBroadcast(
this, ALARM1_ID, myIntent, 0);
AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
assert alarmManager != null;
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 3, pendingIntent);
}
這是觸發通知的 BroadcastReceiver:
public class NotifyService extends BroadcastReceiver {
@SuppressLint("ResourceAsColor")
@Override
public void onReceive(Context context, Intent intent) {
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel("my_channel_01ee",
"Channel human readable titlee",
NotificationManager.IMPORTANCE_HIGH);
channel.enableVibration(true);
channel.setVibrationPattern(new long[]{
0
});
channel.enableLights(true);
channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
channel.setLightColor(Color.GRAY);
channel.enableLights(true);
channel.setDescription("descrioptiom");
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_NOTIFICATION)
.build();
channel.setSound(alarmSound, audioAttributes);
notificationManager.createNotificationChannel(channel);
}
Intent notificationIntent = new Intent(context, FoodInspectorActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder notification = new NotificationCompat.Builder(context, "my_channel_01ee");
int color = 0xfffffff;
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
notification.setSmallIcon(R.drawable.magnifier_final);
notification.setColor(color);
} else {
notification.setSmallIcon(R.drawable.magnifier_final);
}
notification.setContentTitle("FoodScan")
.setContentText("Scan some new products? Just click!")
.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.mipmap.launcher_icon))
.setSound(alarmSound)
.setAutoCancel(true)
.setContentIntent(pendingIntent)
.setDefaults(Notification.DEFAULT_LIGHTS )
.setVibrate(new long[]{0, 500, 1000});
assert notificationManager != null;
notificationManager.notify(5, notification.build());
}
}
使用此代碼,聲音不起作用,振動不起作用,即使取消通知也會連續顯示更多次,即使我將優先級設置為高,它也不會在鎖定時顯示在屏幕上。 超級奇怪
第一步:在你的MainActivity
創建Method並使用AlarmManager
設置指定時間的鬧鍾,並在OnCreate
調用該方法
public void my(){
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY,21);
calendar.set(Calendar.MINUTE,47);
if (calendar.getTime().compareTo(new Date()) < 0)
calendar.add(Calendar.DAY_OF_MONTH, 1);
Intent intent = new Intent(getApplicationContext(),NotificationReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
if (alarmManager != null) {
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY,pendingIntent);
}
}
我每天晚上09:47設置鬧鍾
第 2 步:創建 BroadcastReceiver 以在警報發生時進行偵聽
public class NotificationReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
NotificationHelper notificationHelper = new NotificationHelper(context);
notificationHelper.createNotification();
}
}
我正在創建這個名為NotificationReceiver
類並擴展BroadcastReceiver
,在onReceive
有一個名為NotificationHelper
類,不要混淆,我將在下一步中解釋這個類。
第 3 步:創建 Notification 類
class NotificationHelper {
private Context mContext;
private static final String NOTIFICATION_CHANNEL_ID = "10001";
NotificationHelper(Context context) {
mContext = context;
}
void createNotification()
{
Intent intent = new Intent(mContext , NotificationActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent resultPendingIntent = PendingIntent.getActivity(mContext,
0 /* Request code */, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mContext);
mBuilder.setSmallIcon(R.mipmap.ic_launcher);
mBuilder.setContentTitle("Title")
.setContentText("Content")
.setAutoCancel(false)
.setSound(Settings.System.DEFAULT_NOTIFICATION_URI)
.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O)
{
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "NOTIFICATION_CHANNEL_NAME", importance);
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.enableVibration(true);
notificationChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
assert mNotificationManager != null;
mBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);
mNotificationManager.createNotificationChannel(notificationChannel);
}
assert mNotificationManager != null;
mNotificationManager.notify(0 /* Request Code */, mBuilder.build());
}
}
這個類處理通知
第 4 步:回到第 2 步:並調用通知類
NotificationHelper notificationHelper = new NotificationHelper(context);
notificationHelper.createNotification();
最后去你的AndroidManifest.xml
並注冊這個
<receiver android:name=".NotificationReceiver"/>
