    }

@Override

        return new TimePickerDialog(Main2Activity.this, kTimePickerListener, hour_x, minute_x, true);

            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                hour_x = hourOfDay;
                minute_x = minute;
                Toast.makeText(Main2Activity.this, hour_x + ": " + minute_x, Toast.LENGTH_LONG).show();
            }
        };

Intent 是这样的:(有两个，但它们是一样的，它只是改变了数字)

package app.alexdickson.com.workout1;

import android.annotation.TargetApi;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.Build;
import android.os.IBinder;



public class NotifyService1 extends Service {

    @Override
public IBinder onBind(Intent intent) {
    return null;
}
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
@Override
public void onCreate(){
    Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);


    NotificationManager nNM = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
    Intent intent1 = new Intent(this.getApplicationContext(),Main3Activity.class);
    PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent1, 0);

    Notification mNotify = new Notification.Builder(this)
            .setContentTitle("Hora d'entrenar!")
            .setContentText("Clica per començar entrenament de pit i braços")
            .setSmallIcon(R.mipmap.logo)
            .setContentIntent(pIntent)
            .setSound(sound)
            .build();

    nNM.notify(1,mNotify);

}

这是我的 manifest.xml:

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/logo"
    android:label="@string/app_name"
    android:theme="@style/MyTheme">
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".Main2Activity"
        android:label="@string/title_activity_main2">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity android:name=".Main3Activity" />
    <activity android:name=".Main4Activity"></activity>
</application>

您必须在 AndroidManifest.xml 中注册 NotifyService1 和 NotifyService2。
