android - 位图作为通知图标

Question

我是android新手，我有以下代码:

  URL url = new URL(userpic);
  URLConnection conn = url.openConnection();
  HttpURLConnection httpConn = (HttpURLConnection)conn;
  httpConn.setRequestMethod("GET");
  httpConn.connect();
  if (httpConn.getResponseCode() == HttpURLConnection.HTTP_OK) {
        InputStream inputStream = httpConn.getInputStream();
        Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
        inputStream.close();

        // make a Drawable from Bitmap to allow to set the BitMap
        gdrawable = new BitmapDrawable(bitmap);
        myNotification = new Notification(gdrawable, "Notification!", System.currentTimeMillis());

对于这些代码 "Notification(gdrawable, "Notification!",System.currentTimeMillis());"会出错，它需要我获取 int id。如何获得 gdrawable ID？

Answer 1

可以将图片文件放在res->drawable(或drawable-hdpi,ldpi,mdpi)中，例如notify.png并使用它 myNotification = new Notification(R.id.notify, “通知!”，System.currentTimeMillis());
