Question

我正在开发Android服务。我不知道如何用服务替换这些活动方法。

@Override
protected void onResume() {
    super.onResume();

    checkPlayServices();

    // Resuming the periodic location updates
    if (mGoogleApiClient.isConnected() && mRequestingLocationUpdates) {
        startLocationUpdates();
    }
}

@Override
protected void onStop() {
    super.onStop();
    if (mGoogleApiClient.isConnected()) {
        mGoogleApiClient.disconnect();
    }
}
@Override
protected void onPause() {
    super.onPause();
    stopLocationUpdates();
}

请告诉我如何更换它们

这可以帮助您通过活动实现对服务的回调

将此内容写入您的活动生命周期方法。

Intent intent = new Intent();
intent.setAction("com.example.ON_RESUME");//change this for appropriate callback
sendBroadcast(intent);

更改您的服务

class YourService extends Service {
    @Override
    public IBinder onBind(Intent intent) {
        //Do your stuff
        return null;
    }


    private void onResume() {
        //do your stuff
    }

    private void onStop() {
        //do your stuff
    }

    private void onPause() {
        //do your stuff
    }

    public static class ActivityLifeCycleReceiver extends BroadcastReceiver {

        public String ACTION_ON_RESUME = "com.example.ON_RESUME";
        public String ACTION_ON_STOP = "com.example.ON_STOP";
        public String ACTION_ON_PAUSE = "com.example.ON_PAUSE";

        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (ACTION_ON_PAUSE.equals(action)) {
                onPause();
            } else if (ACTION_ON_RESUME.equals(action)) {
                onResume();
            } else if (ACTION_ON_STOP.equals(action)) {
                onResume();
            }
        }
    }
}

最后在MANIFEST中注册接收器。

    <receiver android:name=".YourService$ActivityLifeCycleReceiver">
        <intent-filter >
            <action android:name="com.example.ON_RESUME"/>
            <action android:name="com.example.ON_STOP"/>
            <action android:name="com.example.ON_PAUSE"/>
        </intent-filter>
    </receiver>
