<? 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" > < TextView android:layout_width = "fill_parent" android:layout_height = "wrap_content" android:text = "@string/hello" /> < Button android:id = "@+id/button" android:layout_width = "fill_parent" android:layout_height = "wrap_content" /> < EditText android:id = "@+id/reciver" android:layout_width = "fill_parent" android:layout_height = "wrap_content" /> < EditText android:id = "@+id/cc" android:layout_width = "fill_parent" android:layout_height = "wrap_content" /> < EditText android:id = "@+id/subject" android:layout_width = "fill_parent" android:layout_height = "wrap_content" /> < EditText android:id = "@+id/body" android:layout_width = "fill_parent" android:layout_height = "wrap_content" /> </ LinearLayout > |
上面是android中实现发送邮件功能的方法之一,还有另外两种方法如下所示:
方法一:
1
2
3
|
Uri uri=Uri.parse( "mailTo:1650***185@qq.com" ); Intent i= new Intent(Intent.ACTION_SENDTO,uri); startActivity(i); |
方法二:
1
2
3

|
Intent i= new Intent(Intent.ACTION_SEND); String[] tos={ "1650***185@qq.com" }; String[] ccs={ "7885***158@qq.com" }; i.putExtra(Intent.EXTRA_EMALL,tos); i.putExtra(Intent.EXTRA_CC,ccs); i.putExtra(Intent.EXTRA_TEXT, "邮件内容" ); i.putExtra(Intent.EXTRA_SUBJECT, "邮件主题" ); i.setType( "message/rfc822" ); startActivity(Intent.createChooser(i, "你的邮件" )); |
如果想在发送的邮件中添加附件,则可以这样写:
1
2
3
4
|
Intent i= new Intent(Intent.ACTION_SEND); i.putExtra(Intent.EXTRA_SUBJECT, "邮件主题" ); i.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/xyz.mp3" ); startActivity(Intent.createChooser(i, "你的邮件" )); |
希望本文所述对大家Android程序设计有所帮助。
