Android界面 NotificationManager使用Bitmap做图标

今天看到EOE问答里面有这“[Android 界面]NotificationManager 如何使用Bitmap做图标”这样一个问题，在论坛搜索也没有好的案例
特写一个简单的demo供大家参考
今天发布的是NotificationManager 使用Bitmap做图标
关键code
代码如下:
public void notification(int flag)
{
Notification notification = new Notification();
//设置statusbar显示的icon
notification.icon = R.drawable.icon;
//设置statusbar显示的文字信息
// myNoti.tickerText= new_msg ;
notification.flags = Notification.FLAG_AUTO_CANCEL;
//设置notification发生时同时发出默认声音
notification.defaults = Notification.DEFAULT_SOUND;
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
Bitmap bitmap=null;
if(flag==0)
{
bitmap=drawableToBitmap(this.getResources().getDrawable(R.drawable.icon));
}else
{
//此处是关键地方，可以从网络或是sdcard上获取图片，转成bitmap就可以
bitmap=drawableToBitmap(this.getResources().getDrawable(R.drawable.alert_dialog_icon));
}
contentView.setImageViewBitmap(R.id.notification_icon, bitmap);
contentView.setTextViewText(R.id.app_name, "Custom notification");
notification.contentView = contentView;
Intent intent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
notification.contentIntent = contentIntent;
//显示Notification
Random random = new Random(new Date().getTime());
mNotificationManager.notify(random.nextInt(1000000), notification);
}
//转化drawableToBitmap
public static Bitmap drawableToBitmap(Drawable drawable)
{
Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), drawable.getOpacity() != PixelFORMat.OPAQUE ? Bitmap.Config.ARGB_8888 : Bitmap.Config.RGB_565);
canvas canvas = new Canvas(bitmap);
drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
drawable.draw(canvas);
return bitmap;
}
