onStartCommand在服务Android中只调用一次？

Question

import android.app.IntentService;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.net.wifi.WifiManager;
import android.os.Handler;
import android.os.IBinder;
import android.os.Looper;
import android.support.annotation.Nullable;
import android.util.Log;
import android.widget.Toast;




/**
 * An {@link IntentService} subclass for handling asynchronous task requests in
 * a service on a separate handler thread.
 * <p>
 * TODO: Customize class - update intent actions and extra parameters.
 */
public class WiFiCheck extends Service {




    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // Let it continue running until it is stopped.


        Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();


        return super.onStartCommand(intent, flags, startId);

    }

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



    /**
     * Handle action Foo in the provided background thread with the provided
     * parameters.
     */
    private void handleActionFoo(String param1, String param2) {
        // TODO: Handle action Foo
        throw new UnsupportedOperationException("Not yet implemented");
    }

    /**
     * Handle action Baz in the provided background thread with the provided
     * parameters.
     */
    private void handleActionBaz(String param1, String param2) {
        // TODO: Handle action Baz
        throw new UnsupportedOperationException("Not yet implemented");
    }
}

return START_STICKY;

        startService(new Intent(this, WiFiCheck.class));

但还是没用。有什么帮助吗

如果您再次启动服务，吐司将被调用两次或更多次

例如。

startService(new Intent(this, WiFiCheck.class));

new intent是位于onstartCommand（intent intent中的一个intent
