Question

如何获得推送并发送推送。我想接收推送消息并在活动上显示消息，我尝试过以下操作，但找不到ParsePushBrodcastReciver。

我能够发送它并收到它，但我无法将信息保存在某个变量中

package com.parse.starter;

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import android.util.Log;


public class ParsePushReciever extends ParsePushBroadcastReceiver {


@Override
public void onPushOpen(Context context, Intent intent) {
    AppLog.e("Push", "Clicked");
    Intent i = new Intent(context, MainActivity.class);
    i.putExtras(intent.getExtras());
    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(i);
}

@Override
public void onReceive(Context context, Intent intent) {
    Log.d("Push Notification",intent.getExtras().get(ParsePushBroadcastReceiver.KEY_PUSH_DATA).toString());
    NotificationManager nm=(NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(context);

    builder.setSmallIcon(R.drawable.launcher);

    Intent newIntent=new Intent(context,MainActivity.class);
    newIntent.putExtra(context.getString(R.string.navigation_from_notification),true);
    newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
            Intent.FLAG_ACTIVITY_CLEAR_TASK);
    PendingIntent pi=PendingIntent.getActivity(context, 0, newIntent, 0);

    builder.setContentIntent(pi);

    builder.setContentText("Push Notification");

    Log.d("Notification", strMsg);

    nm.notify(1, builder.build());
}
}

public static void generateNotification(Context context, String title, String message, String action) {
  // Show the notification
  NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
        .setSmallIcon(R.drawable.ic_launcher).setContentTitle(title).setContentText(message)
        .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_launcher));
  Intent intent = new Intent(context, SplashScreen.class);
  intent.putExtra(KEY_TITLE, title);
  intent.putExtra(KEY_BODY, message);
  intent.setAction(action);
  intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
  Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
  mBuilder.setSound(soundUri);
  // Creates an explicit intent for an Activity in your app

  TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
  stackBuilder.addParentStack(SplashScreen.class);
  stackBuilder.addNextIntent(intent);
  PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
  mBuilder.setContentIntent(resultPendingIntent);
  NotificationManager mNotificationManager = (NotificationManager) context
        .getSystemService(Context.NOTIFICATION_SERVICE);
  // used for random integer generation
  mBuilder.setAutoCancel(true);
  Random random = new Random();

  mNotificationManager.notify(random.nextInt(), mBuilder.build());
  Vibrator v = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
  // Vibrate for 500 milliseconds
  if (v != null)
     v.vibrate(1000);
  }

尝试使用此代码生成通知，并在意图中打开包含所需消息的通知。

这个小代码可以通过推送获得所有文本，你可以用它来做你的事情：

@Override
public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);
    JSONObject json = null;
    try {
        json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
        String text = json.getString("alert").toString();
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

将它放在onReceive（）方法中。

我希望这对你有所帮助。

我找到了有用的例子

public class MyCustomReceiver extends BroadcastReceiver {
   private static final String TAG = "MyCustomReceiver";
   public static final String intentAction = "SEND_PUSH";

   @Override
   public void onReceive(Context context, Intent intent) {
       if (intent == null) {
           Log.d(TAG, "Receiver intent null");
       } else {
          // Parse push message and handle accordingly
          processPush(context, intent);
       }
   }

   private void processPush(Context context, Intent intent) {
       String action = intent.getAction();
       Log.d(TAG, "got action " + action );
       if (action.equals(intentAction))
       {
           String channel = intent.getExtras().getString("com.parse.Channel");
           try {        
               JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));
               Log.d(TAG, "got action " + action + " on channel " + channel + " with:");
               // Iterate the parse keys if needed
               Iterator<String> itr = json.keys();
               while (itr.hasNext()) {
                   String key = (String) itr.next();
               // Extract custom push data
               if (key.equals("customdata")) {    
                // Handle push notification by invoking activity directly
                launchSomeActivity(context, json.getString(key));
                // OR trigger a broadcast to activity
                triggerBroadcastToActivity(context);
                // OR create a local notification
                createNotification(context);
                }
                    Log.d(TAG, "..." + key + " => " + json.getString(key));
               }
            } catch (JSONException ex) {
            Log.d(TAG, "JSON failed!");
            }
       }
   }

   public static final int NOTIFICATION_ID = 45;
   // Create a local dashboard notification to tell user about the event
   private void createNotification(Context context) {
       NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context).setSmallIcon(
               R.drawable.ic_launcher).setContentTitle("Successfully logged in");
       NotificationManager mNotificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
       mNotificationManager.notify(45, mBuilder.build());
   }

   // Handle push notification by invoking activity directly
   private void launchSomeActivity(Context context, String datavalue) {
       Intent pupInt = new Intent(context, ShowPopUp.class);
       pupInt.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK );
       pupInt.putExtra("customdata", datavalue);
       context.getApplicationContext().startActivity(pupInt);   
   }

   // Handle push notification by sending a local broadcast 
   // to which the activity subscribes to
   private void triggerBroadcastToActivity(Context context) {
       LocalBroadcastManager.getInstance(context).sendBroadcast(new Intent(intentAction));
   }
}

为此...这将有助于你

并且不要忘记将广播Receiver添加到Manifest

 <receiver
        android:name=".MyReceiver"
        android:exported="false" >
        <intent-filter>
            <action android:name="com.parse.push.intent.RECEIVE" />
            <action android:name="com.parse.push.intent.DELETE" />
            <action android:name="com.parse.push.intent.OPEN" />
        </intent-filter>
    </receiver>

解析发送和接收，而不是ParsePushBroadcastReceiver
