Android 收到通知时如何在应用程序中打开mainactivity的webview

我正在使用GCM制作webview android应用程序

当我从服务器向android应用程序调用消息时

我可以在我的手机里得到完美的通知

如果单击，则可以在应用程序中看到Mainactivity

但我想改进一下

---

比如说,

GCM服务器发送一个特殊的url，然后如果我点击电话通知

我想在我的应用程序中检查webview的此url

我的消息来源是这样的

public class GcmMessageHandler extends IntentService {

 String mes; 
 String cont;

String  title_name ;
String board;
String idx;
String pg;
 private Handler handler;
 private Bitmap bmBigPicture;
 private WebView webview;

public GcmMessageHandler() {
    super("GcmMessageHandler");
}

@Override
public void onCreate() {
    // TODO Auto-generated method stub
    super.onCreate();
    handler = new Handler();
}
@Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();        
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    // The getMessageType() intent parameter must be the intent you received
    // in your BroadcastReceiver.
    String messageType = gcm.getMessageType(intent);

    bmBigPicture = BitmapFactory.decodeResource(getResources(), R.drawable.message);
    mes = extras.getString("title");
    cont = extras.getString("message");
    String msg = cont;
    title_name =  msg.substring(msg.indexOf("@@@")+3,msg.length()); //"title_name"    
    board = msg.substring(0, msg.indexOf("!!!")); //idx
    idx = msg.substring(msg.indexOf("!!!")+3, msg.indexOf("///")); //idx
    pg = msg.substring(msg.indexOf("///")+3,msg.indexOf("@@@")); //"pg"

    if(extras.getString("title") != null){         
            NotificationManager manager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
            Notification notification = null;

            PendingIntent intent1 = PendingIntent.getActivity(this, 0,  new Intent(this, MainActivity.class), PendingIntent.FLAG_CANCEL_CURRENT);

                notification = new Notification.BigPictureStyle(
                        new Notification.Builder(getApplicationContext())                           
                            .setSmallIcon(R.drawable.ic_launcher)
                            .setPriority(Notification.PRIORITY_MAX)
                            .setLargeIcon(bmBigPicture)
                             .setAutoCancel(true)       
                             .setVibrate(new long[] { 1000, 1000, 1000 })
                             .setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE)
                                .setContentIntent(intent1)
                                .setContentTitle(title_name))                               
                        .bigPicture(bmBigPicture)                       
                        .build();       

            manager.notify(1234, notification);             
            showToast();
            Log.i("GCM", "Received : (" +messageType+")  "+extras.getString("title") ); 
            GcmBroadcastReceiver.completeWakefulIntent(intent);    

    }        
}


public void showToast(){

    handler.post(new Runnable() {
        public void run() {

            Toast.makeText(getApplicationContext(), title_name , Toast.LENGTH_LONG).show();                 
            startActivity(new Intent(getApplicationContext(),MyDialog.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK).putExtra("title", cont));
        }
    });

}

}

}

}

试试下面的一个

 private void sendNotification(String msg, String url)
    {
        mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);

        Intent m_intent = new Intent(this, MainActivity.class);
        m_intent.putExtra("url", url); // Receive this in main activity in bundle
        m_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, m_intent, PendingIntent.FLAG_CANCEL_CURRENT);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this).setSmallIcon(R.drawable.notification_small).setContentTitle(getString(R.string.app_name)).setStyle(new NotificationCompat.BigTextStyle().bigText(msg)).setContentText(msg).setAutoCancel(true).setSound(Settings.System.DEFAULT_NOTIFICATION_URI);
        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());


    }

我的应用程序不工作，我看不到“google.com”网站，当我点击alertdialog中的“ok”按钮时，只有我的应用程序启动了…webview显示了默认url我试图通过此修改，我也可以完美地获得相同的消息，但应用程序无法移动url，只需停留在mainactivity中…啊！现在我了解了意图，我尝试在mainactivity中创建意图，我成功了！非常感谢！！！

private class WebViewClientClass extends WebViewClient { 
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) { 
    view.loadUrl(url);         
    return true; 
} 
@Override
public void onPageFinished(WebView view, String url) {
    // TODO Auto-generated method stub
    super.onPageFinished(view, url);

    if(pd.isShowing()) {
        pd.dismiss();
    }
}
public void onLoadResource (WebView view, String url) {
    if (pd == null) {
        pd = new ProgressDialog(MainActivity.this);
        pd.setMessage("Chargement en cours");
        pd.show();
    }
}

private void setLayout(){
mWebView = (WebView) findViewById(R.id.webview);

public class MyDialog extends Activity {
public String idx = "";
public String pg = "";

public String board = "";
@Override

    super.onCreate(savedInstanceState);
    Intent intent = getIntent();
    String title = intent.getExtras().getString("title");

    // board + "!!!" + idx + "///" + pg + "@@@" + vo.getTitle()
    // String temp1 = title.substring(title.indexOf("///"),title.indexOf("///")+3); // "/// "
    board = title.substring(0, title.indexOf("!!!")); //idx
    idx = title.substring(title.indexOf("!!!")+3, title.indexOf("///")); //idx
    pg = title.substring(title.indexOf("///")+3,title.indexOf("@@@")); //"pg"
    title_name =  title.substring(title.indexOf("@@@")+3,title.length()); //"title_name"

     }});
    myAlertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
