我有一个包含服务的 android 应用程序。现在我想在另一个应用程序中访问该服务。我怎样才能做到这一点？我在网上找到了这个应用程序。请在下面找到代码 fragment

1>
public class LocalWordService extends Service {

    private final IBinder mBinder = new MyBinder();
    private ArrayList<String> list = new ArrayList<String>();

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        Random random = new Random();
        if (random.nextBoolean()) {
            list.add("Linux");
        }
        if (random.nextBoolean()) {
            list.add("Android");
        }
        if (random.nextBoolean()) {
            list.add("iPhone");
        }
        if (random.nextBoolean()) {
            list.add("Windows7");
        }
        if (list.size() >= 20) {
            list.remove(0);
        }
        return Service.START_NOT_STICKY;
    }

    @Override
    public IBinder onBind(Intent arg0) {
        return mBinder;
    }

    public class MyBinder extends Binder {
        LocalWordService getService() {
            return LocalWordService.this;
        }
    }

    public List<String> getWordList() {
        return list;
    }

}

public class MyScheduleReceiver extends BroadcastReceiver {


    // Restart service every 30 seconds
        private static final long REPEAT_TIME = 1000 * 30;

        @Override
        public void onReceive(Context context, Intent intent) {
            AlarmManager service = (AlarmManager) context
                    .getSystemService(Context.ALARM_SERVICE);
            Intent i = new Intent(context, MyStartServiceReceiver.class);
            PendingIntent pending = PendingIntent.getBroadcast(context, 0, i,
                    PendingIntent.FLAG_CANCEL_CURRENT);
            Calendar cal = Calendar.getInstance();
            // Start 30 seconds after boot completed
            cal.add(Calendar.SECOND, 30);
            //
            // Fetch every 30 seconds
            // InexactRepeating allows Android to optimize the energy consumption
            service.setInexactRepeating(AlarmManager.RTC_WAKEUP,
                    cal.getTimeInMillis(), REPEAT_TIME, pending);

            // service.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
            // REPEAT_TIME, pending);

        }

}

public class MyStartServiceReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent service = new Intent(context, LocalWordService.class);
        context.startService(service);
    }

}

public class MyService extends Service {

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

}

list 文件如下

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="de.vogella.android.ownservice.local.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <service
            android:name="de.vogella.android.ownservice.local.LocalWordService"
            android:icon="@drawable/ic_launcher"
            android:label="@string/service_name" >
        </service>

         <service
            android:name="de.vogella.android.ownservice.local.MyService"
            android:process=":meinprocess"
            android:icon="@drawable/ic_launcher"
            android:label="@string/service_name" >
        </service>

        <receiver android:name="de.vogella.android.ownservice.local.MyScheduleReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>
        <receiver android:name="de.vogella.android.ownservice.local.MyStartServiceReceiver" >
        </receiver>
    </application>

最佳答案

需要为服务使用 Intent 过滤器，例如我们声明的“LocalWordService”

<service
                    android:enabled="true"
                    android:exported="true"
                    android:name="de.vogella.android.ownservice.local.MyService">
        <intent-filter>
            <action android:name="de.vogella.android.ownservice.local.START_SERVICE" />
        </intent-filter>
        </service>

在调用应用中，我们只需要添加获取服务的行

Intent intent=new Intent("de.vogella.android.ownservice.local.START_SERVICE");  
                startService(intent);

就是这样。
