在我的代碼中，我有一個接收傳入SMS的廣播接收器。 如果消息來自特定的號碼，並以「位置」字開頭，我想顯示通知。當用戶單擊通知時，我需要打開Google Map，指出消息中包含的位置。 但即使沒有點擊通知，Google地圖也會打開。 這裏是我的代碼從通知打開默認地圖應用程序
if (message.startsWith("Location")) {
// abort
abortBroadcast();
String[] locationMessage = message.split(":");
String latitude = locationMessage[2];
String longitude = locationMessage[3];
String trueLocation = locationMessage[8];
float lat = Float.parseFloat(latitude);
float lon = Float.parseFloat(longitude);
Uri gmmIntentUri = Uri.parse("geo:" + lat + "," + lon + "?q=" + lat + "," + lon); // URI encoding
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps"); // Check if there is map app installed
mapIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
if (mapIntent.resolveActivity(context.getPackageManager()) != null) {
//context.startActivity(mapIntent); // If map app is there starts map app
if (trueLocation.equals("false")) {
notification(context, "Find Pal", "GPS is turned off from Other side: Location", latitude, longitude, mapIntent);
} else {
notification(context, "Find Pal", "Location", latitude, longitude, mapIntent);
}
}
}
private void notification(Context context, String s, String s1, String latitude, String longitude, Intent mapIntent) {
NotificationCompat.Builder mBuilder =
(NotificationCompat.Builder) new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.notification_icon_two)
.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.findpal_actionbar_icon))
.setContentTitle(s)
.setWhen(System.currentTimeMillis())
.setContentText(s1 + ":" + latitude + "," + longitude)
.setAutoCancel(true);
PendingIntent intent2 = PendingIntent.getBroadcast(context, 1, mapIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(intent2);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());
}
