如何使按钮打开 [英] How to make button open

问题描述

我遇到问题，当用户点击它时，我需要我的发送按钮将电子邮件发送到我的按钮。我只是想到达哪里，当用户点击发送按钮时，该按钮已经知道我的电子邮件地址并自动发送到那里的电子邮件。

I have a problem, I need my 'Send' button to send the email to my button when the user clicks on it. I just want to get where, when users click send Button then the button will already know my email address and send it to there E-mail automatically.

到目前为止，我的 EmailActivity.java

import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.ComponentName;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;


public class EmailActivity extends Activity {

Button buttonSend;
EditText textTo;
EditText textSubject;
EditText textMessage;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.email_layout);

buttonSend = (Button) findViewById(R.id.buttonSend);
textTo = (EditText) findViewById(R.id.editTextTo);
textSubject = (EditText) findViewById(R.id.editTextSubject);
textMessage = (EditText) findViewById(R.id.editTextMessage);

buttonSend.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {

        String to = textTo.getText().toString();
        String subject = textSubject.getText().toString();
        String message = textMessage.getText().toString();

        Intent email = new Intent(Intent.ACTION_SEND);
        email.putExtra(Intent.EXTRA_EMAIL, new String[]{ to});
        //email.putExtra(Intent.EXTRA_CC, new String[]{ to});
        //email.putExtra(Intent.EXTRA_BCC, new String[]{to});
        email.putExtra(Intent.EXTRA_SUBJECT, subject);
        email.putExtra(Intent.EXTRA_TEXT, message);

        //need this to prompts email client only
        email.setType("message/rfc822");

        startActivity(Intent.createChooser(email, "Choose an Email client :"));

    }
});
}

email_layout.xml ：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
