Question

我遇到了问题，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，按钮就会知道我的电子邮件地址并自动发送到那里的电子邮件。

到目前为止，我的 EmailActivity.java

中有这个

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"
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<TextView
android:id="@+id/textViewPhoneNo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="To : "
android:textAppearance="?android:attr/textAppearanceLarge" />

<EditText
android:id="@+id/editTextTo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress" >

<requestFocus />

</EditText>

<TextView
android:id="@+id/textViewSubject"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Subject : "
android:textAppearance="?android:attr/textAppearanceLarge" />

<EditText
android:id="@+id/editTextSubject"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
</EditText>

<TextView
android:id="@+id/textViewMessage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Message : "
android:textAppearance="?android:attr/textAppearanceLarge" />

<EditText
android:id="@+id/editTextMessage"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="top"
android:inputType="textMultiLine"
android:lines="5" />

<Button
android:id="@+id/buttonSend"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Send" />

Answer 1

Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
            "mailto","email@email.com", null));
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(intent, "Choose an Email client :"));
