我跟着這些tutorial，我得到了通知。但我想設置計數並使其與圖標可見，並且我想拖動和關閉通知，如Facebook。如何在通知區域和桌面通知（如Facebook）中設置通知計數？
這是我的代碼。爲了增加通知我按照這個link
@Override
public void onCreate() {
super.onCreate();
context = this;
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
Bitmap bm = BitmapFactory.decodeResource(getResources(),
R.drawable.ic_launcher);
chatHead = new ImageView(this);
chatHead.setImageBitmap(getCircleBitmap(bm, 200));
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.TYPE_PHONE,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;
params.x = 0;
params.y = 100;
setBadge(context, count++);
chatHead.setOnTouchListener(new View.OnTouchListener() {
private int initialX;
private int initialY;
private float initialTouchX;
private float initialTouchY;
@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
initialX = params.x;
initialY = params.y;
initialTouchX = event.getRawX();
initialTouchY = event.getRawY();
return true;
case MotionEvent.ACTION_UP:
return true;
case MotionEvent.ACTION_MOVE:
params.x = initialX + (int) (event.getRawX() - initialTouchX);
params.y = initialY + (int) (event.getRawY() - initialTouchY);
windowManager.updateViewLayout(chatHead, params);
return true;
}
return false;
}
});
windowManager.addView(chatHead, params);
}
public static void setBadge(Context context, int count) {
String launcherClassName = getLauncherClassName(context);
if (launcherClassName == null) {
return;
}
Intent intent = new Intent("android.intent.action.BADGE_COUNT_UPDATE");
intent.putExtra("badge_count", count);
intent.putExtra("badge_count_package_name", context.getPackageName());
intent.putExtra("badge_count_class_name", launcherClassName);
context.sendBroadcast(intent);
}
public static String getLauncherClassName(Context context) {
PackageManager pm = context.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> resolveInfos = pm.queryIntentActivities(intent, 0);
for (ResolveInfo resolveInfo : resolveInfos) {
String pkgName = resolveInfo.activityInfo.applicationInfo.packageName;
if (pkgName.equalsIgnoreCase(context.getPackageName())) {
String className = resolveInfo.activityInfo.name;
return className;
}
}
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
return START_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
if (chatHead != null) windowManager.removeView(chatHead);
}
private Bitmap getCircleBitmap(Bitmap bitmap, int pixels) {
final Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
bitmap.getHeight(), Bitmap.Config.ARGB_8888);
final Canvas canvas = new Canvas(output);
// int pixels;
final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
final RectF rectF = new RectF(rect);
final float roundPx = pixels;
paint.setShadowLayer(2, 2, 2, 0xff424242);
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawRoundRect(rectF, roundPx, roundPx, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
bitmap.recycle();
return output;
}
我也想使其可見與GCM通知計數。我用GCM消息設置了計數。但它不可見。
private void sendNotification(String msg) {
int numMessages = 0;
Intent inservice = new Intent(this, ChatService.class);
startService(inservice);
mNotificationManager = (NotificationManager) this
.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
new Intent(this, MainActivity.class), 0);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
this).setSmallIcon(R.drawable.ic_stat_gcm)
.setContentTitle("Contact Received")
.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
.setContentText(msg)
.setDefaults(Notification.DEFAULT_VIBRATE)
.setNumber(numMessages++)
.setSound(Uri.parse("android.resource://" + getPackageName() + "/" +R.raw.sounds1));
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
任何人都可以給我一些工作的例子嗎？
