übertragen Ich habe die Klasse "MyGcmListenerService", die Json vom Server bekommt. Ich möchte die Zeichenfolge aus dem JSON und senden Sie es an die MainActivity und aktiv eine Methode. Mir wurde gesagt, dass ich Listener und auch mit Schnittstelle verwenden kann. Nun, ich weiß nicht wirklich, wie man es benutzt. Kann mir bitte jemand helfen?Android - Wie Daten zwischen Klassen witn LISENTER
Dies ist MyGcmListenerService Code
package com.world.bolandian.watchmesensor;
import android.app.NotificationManager;
import android.app.PendingIntent;

import android.media.RingtoneManager;

import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
import android.util.Log;
import com.google.android.gms.gcm.GcmListenerService;
public class MyGcmListenerService extends GcmListenerService {
private static final String TAG = "MyGcmListenerService";
/**

@Override
public void onMessageReceived(String from, Bundle data) {
String message = data.getString("typemessage");
Log.d(TAG, "From: " + from);
Log.d(TAG, "Message: " + message);
if (from.startsWith("/topics/")) {
// message received from some topic.
} else {
// normal downstream message.
}
// [START_EXCLUDE]
/**

/**

*/
sendNotification(message);
// [END_EXCLUDE]
}
// [END receive_message]
/**

private void sendNotification(String message) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.common_google_signin_btn_icon_dark)

}
Dies ist der MainActivity
package com.world.bolandian.watchmesensor;
import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;
import android.widget.Toast;
import com.google.gson.Gson;
public class MainActivity extends Activity implements SensorEventListener, Listen{
Sensor accelerometer;
SensorManager sm;
TextView acceleration;
SendValues sv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sm = (SensorManager)getSystemService(SENSOR_SERVICE);
accelerometer = sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
sm.registerListener(this,accelerometer, SensorManager.SENSOR_DELAY_NORMAL);
acceleration = (TextView)findViewById(R.id.sensorTxt);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onSensorChanged(SensorEvent event) {
acceleration.setText("X: " + event.values[0] +
"\nY: " + event.values[1] +
"\nZ: " + event.values[2]);
// get the phone number from the login
SharedPreferences sh = getSharedPreferences("BikePhone", Context.MODE_PRIVATE);
String phone = sh.getString(Params.PHONE,null);
if (event.values[0] >=5.000 || (event.values[0] <= -5.000) || (event.values[1] >= 5.000) || (event.values[1] <= -5.000))
{
sv = new SendValues(phone,"1");
Gson g = new Gson();
String ans = g.toJson(sv,SendValues.class);
send(sv);
}
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
}
public void send (SendValues sv)
{
SendThreadCommunication con;
ServerRequest ser = new ServerRequest();
ser.setResponse(this);
Gson gson = new Gson();
String send = gson.toJson(sv,SendValues.class);
ser.addParamaters(Params.VALUES, send);
ser.addServerName(Params.SERVER_URL);
ser.addServletName(Params.BIKE_TO_USER);
con = new SendThreadCommunication(ser);
con.start();
}
@Override
public void good() {
}
@Override
public void notGood() {
}
@Override
public void userGcmNotRegistered() {
Toast.makeText(getApplication(), "There is some problem, please register again to the App", Toast.LENGTH_LONG).show();
}
}
Und das ist die Schnittstelle
package com.world.bolandian.watchmesensor;
public interface Listen {
public void good();
public void notGood();
}
