我可以在後臺發送電子郵件,但無法弄清楚爲什麼使用「Mail.java」類中的addAttachment()方法不起作用。我到處尋找答案,但只找到了「相似」的答案,沒有幫助。我想要的只是從我的res/drawable文件夾發送圖像。發送電子郵件(在後臺)工作,添加附件不
我目前從steveholt55's Github借用代碼嘗試獲取附件發送..但仍然沒有運氣。到目前爲止,電子郵件在我的活動中沒有添加addAttachment()行,這是個好消息。但我也需要這個附件才能發送。
Mail.Java文件在下面,但我認爲這個問題是在我的代碼中的某處..特別是我試圖在我的活動中添加附件。 addAttachment()方法只請求一個字符串值。我想知道我是否在給它錯誤的道路?從我的活動
代碼:
if(!sent){
try{
String[] recipients = {"[email protected]"};
SendEmailAsyncTask email = new SendEmailAsyncTask();
email.m = new Mail(Config.EMAIL,Config.PASSWORD);
email.m.set_from("[email protected]");
email.m.setBody("Body Text");
email.m.set_subject("Subject Text");
email.m.set_to(recipients);
email.m.addAttachment("res/drawable-hdpi/add_down.png");
email.execute();
} catch(Exception e){e.printStackTrace();}
}
這裏是異步類:
class SendEmailAsyncTask extends AsyncTask<Void, Void, Boolean> {
Mail m;
public SendEmailAsyncTask() { }
@Override
protected Boolean doInBackground(Void... params) {
boolean returnvalue = false;
try {
if (m.send())
returnvalue = true;
} catch (Exception e) {
e.printStackTrace();
}
return returnvalue;
}
}
下面是Mail.Java類:

obviosuly你不能繪製文件是這樣的... 1.搶繪製對象,2.將其保存到了一些路徑,使用此路徑?如何做到既1和2在bazillions的回答類似的問題在這裏 – Selvin
謝謝 - 請儘量不要粗魯。我不是專家,我正在學習。我一直在努力工作超過30個小時。這個項目是由我的老闆隨意拋給我的,他預計這個工作會在另一天完成。 – FoxDonut
你可以像這樣得到可繪製路徑Uri path = Uri.parse(「android.resource://」+ BuildConfig.APPLICATION_ID +「/」+ R.drawable.image),你可以像那樣使用fileName – Kayra
