android - 如何在android中创建忘记密码？

Question

我想要一个使用“忘记密码”的应用程序。我有一个名为忘记密码的 TextView。当我点击它时，它会显示一个带有编辑文本的弹出窗口，我可以在其中写入电子邮件地址，当我点击“确定”按钮时，它会在我的邮件 ID 上发送新密码。我将 JSSEProvider 类用于协议(protocol)。

public final class JSSEProvider extends Provider {

public JSSEProvider() {
    super("HarmonyJSSE", 1.0, "Harmony JSSE Provider");
    AccessController.doPrivileged(new java.security.PrivilegedAction<Void>() {
        public Void run() {
            put("SSLContext.TLS",
                    "org.apache.harmony.xnet.provider.jsse.SSLContextImpl");
            put("Alg.Alias.SSLContext.TLSv1", "TLS");
            put("KeyManagerFactory.X509",
                    "org.apache.harmony.xnet.provider.jsse.KeyManagerFactoryImpl");
            put("TrustManagerFactory.X509",
                    "org.apache.harmony.xnet.provider.jsse.TrustManagerFactoryImpl");
            return null;
        }
    });
}
}

public class GMailSender extends javax.mail.Authenticator {

    // Send this email in Async task, otherwise NetworkOnMainThread Exception will be thrown
    new MobiSnifferAsync().execute();

    }catch(Exception e){

但不知道如何在电子邮件 ID 上发送密码。谁能告诉我，我该怎么做。

Answer 1

试试这个非常简单的函数..

    protected void sendEmail() {
      Log.i("Send email", "");

      String[] TO = {"amrood.admin@gmail.com"};
      String[] CC = {"mcmohd@gmail.com"};
      Intent emailIntent = new Intent(Intent.ACTION_SEND);
      emailIntent.setData(Uri.parse("mailto:"));
      emailIntent.setType("text/plain");


      emailIntent.putExtra(Intent.EXTRA_EMAIL, TO);
      emailIntent.putExtra(Intent.EXTRA_CC, CC);
      emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Your subject");
      emailIntent.putExtra(Intent.EXTRA_TEXT, "Email message goes here");

      try {
         startActivity(Intent.createChooser(emailIntent, "Send mail..."));
         finish();
         Log.i("Finished sending email...", "");
      } catch (android.content.ActivityNotFoundException ex) {
         Toast.makeText(MainActivity.this, 
         "There is no email client installed.", Toast.LENGTH_SHORT).show();
      }
   }

将您的密码和其他文本添加为​​ Intent.EXTRA_TEXT 的值..
