Big Picture Notification in android -


i have done android push notification using fcm.but when trying big picture notification it's not showing full image in notificationn bar.left , right side of image getting cropped.please let me know how fix issue.i tried giving 512*256 image , 600*300 size images.

i have used glide library loading image url... have loaded image using big picture notification.

public class imagenotification extends appcompatactivity {     public bitmap image ,bmp;     public notificationcompat.builder nb;     final string url = "https://www.google.es/images/srpr/logo11w.png";      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_image_notification);       }      public void createnotification(view view) {         // prepare intent triggered if         // notification selected         intent intent = new intent(this, notificationreceiveractivity.class);         pendingintent pintent = pendingintent.getactivity(this, (int) system.currenttimemillis(), intent, 0);          nb = new notificationcompat.builder(this);         nb.setsmallicon(r.drawable.icon);         nb.setcontenttitle("image notification");         nb.setcontenttext("set content text");         nb.setticker("set ticker text");           glide.                 with(this).                 load(url).                 asbitmap()                 .centercrop()                 .into(new simpletarget<bitmap>(100,100) {                           @override                           public void onresourceready(bitmap resource, glideanimation<? super bitmap> glideanimation) {                                notificationcompat.bigpicturestyle bps = new notificationcompat.bigpicturestyle().bigpicture(resource);                               bps.setsummarytext("summary text appears on expanding notification");                               nb.setstyle(bps);                            }                       });               taskstackbuilder tsb = taskstackbuilder.create(this);         tsb.addparentstack(imagenotification.class);         // adds intent starts activity top of stack         tsb.addnextintent(intent);         pendingintent resultpendingintent =                 tsb.getpendingintent(                         0,                         pendingintent.flag_update_current                 );          nb.setcontentintent(resultpendingintent);         nb.setautocancel(true);         nb.setdefaults(notification.default_lights | notification.default_vibrate);         uri alarmsound = ringtonemanager.getdefaulturi(ringtonemanager.type_notification);         nb.setsound(alarmsound, audiomanager.stream_music);         notificationmanager mnotificationmanager =                 (notificationmanager) this.getsystemservice(context.notification_service);         // mid allows update notification later on.         mnotificationmanager.notify(11221, nb.build());     }  }

if loading image mipmap or drawable can replace code written glide library using below code

bitmap bitmap_image = bitmapfactory.decoderesource(this.getresources(), r.drawable.picture);       notificationcompat.bigpicturestyle s = new notificationcompat.bigpicturestyle().bigpicture(bitmap_image);        s.setsummarytext("summary text appears on expanding notification");         nb.setstyle(s);

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
