Question

我试图通过qt发送电子邮件我使用了这段代码，但我发现了这个错误＆＃34; 4 ----＆＃34; 502 5.5.1无法识别的命令。 q9sm1859778wjo.9 - gsmtp \ n＆＃34;并感谢您的帮助。 smrp.h

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Display;
import android.view.ViewGroup;
import android.widget.LinearLayout;

import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    LinearLayout buttonContainer, indicatorContainer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        /* getting display size */
        Display display = getWindowManager().getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);
        int width = size.x;
        int height = size.y;

        /* set button size */
        int buttonWidthSize = (int) (width / 2.5);
        int buttonHeightSize = (int) (height / 5.0);

        buttonContainer = (LinearLayout)findViewById(R.id.buttonContainer);
        indicatorContainer = (LinearLayout)findViewById(R.id.indicatorContainer);



        for(int i = 1; i <= 10 ; i++){
            Button button = new Button(this);
            button.setText("button"+i);
            button.setWidth(buttonWidthSize);

            buttonContainer.addView(button, new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
        }

        // how it can be solved.

这与Qt无关，只是SMTP设置。

从您的代码中我看到您正在使用gmail和端口25.这是不正确的，将您的传出端口更改为465，请参阅here
