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

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;
}
