类似SMS，Android系统同样支持通过编码的方式发送Email。
1. 新建一个工程，Emails。
2. 修改main.xml文件。

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

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

</LinearLayout>

3. EmailsActivity.java中的代码。

public class EmailsActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }    
  
    public void onClick(View v) {
        String[] to = 
            {"someguy@yourcompany.com", 
        	 "anotherguy@yourcompany.com"};
        String[] cc = {"busybody@yourcompany.com"};
        sendEmail(to, cc, "Hello", "Hello my friends!");
    }
    
    //?sends an SMS message to another device?
    private void sendEmail(String[] emailAddresses, String[] carbonCopies,
    String subject, String message)
    {
        Intent emailIntent = new Intent(Intent.ACTION_SEND);
        emailIntent.setData(Uri.parse("mailto:"));
        String[] to = emailAddresses;
        String[] cc = carbonCopies;
        emailIntent.putExtra(Intent.EXTRA_EMAIL, to);
        emailIntent.putExtra(Intent.EXTRA_CC, cc);
        emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
        emailIntent.putExtra(Intent.EXTRA_TEXT, message);
        emailIntent.setType("message/rfc822");
        startActivity(Intent.createChooser(emailIntent, "Email"));
    }    
}

4. 调试。



这里，唯一要做的就是新建一个Intent对象，然后设置相应的参数。

Intent emailIntent = new Intent(Intent.ACTION_SEND);
        emailIntent.setData(Uri.parse("mailto:"));
        String[] to = emailAddresses;
        String[] cc = carbonCopies;
        emailIntent.putExtra(Intent.EXTRA_EMAIL, to);
        emailIntent.putExtra(Intent.EXTRA_CC, cc);
        emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
        emailIntent.putExtra(Intent.EXTRA_TEXT, message);
        emailIntent.setType("message/rfc822");
        startActivity(Intent.createChooser(emailIntent, "Email"));
