安卓跳转邮件页面

在Android中，调用Email有三种类型的Intent： Intent.ACTION_SENDTO 无附件的发送 Intent.ACTION_SEND 带附件的发送 Intent.ACTION_SEND_MULTIPLE 带有多附件的发送 

【方法1】使用SENTTO发送 

Intent data= new  Intent(Intent.ACTION_SENDTO);
data.setData(Uri.parse( "mailto:[email protected]" ));
data.putExtra(Intent.EXTRA_SUBJECT,  "这是标题" );
data.putExtra(Intent.EXTRA_TEXT,  "这是内容" );
startActivity(data);
Intent data= new  Intent(Intent.ACTION_SENDTO);
data.setData(Uri.parse( "mailto:[email protected]" ));
data.putExtra(Intent.EXTRA_SUBJECT,  "这是标题" );
data.putExtra(Intent.EXTRA_TEXT,  "这是内容" );
startActivity(data);

【方法2】使用SEND发送 

Intent intent =  new  Intent(Intent.ACTION_SEND);
String[] tos = {  "[email protected]"  };
String[] ccs = {  "[email protected]"  };
String[] bccs = { "[email protected]" };
intent.putExtra(Intent.EXTRA_EMAIL, tos);
intent.putExtra(Intent.EXTRA_CC, ccs);
intent.putExtra(Intent.EXTRA_BCC, bccs);
intent.putExtra(Intent.EXTRA_TEXT,  "body" );
intent.putExtra(Intent.EXTRA_SUBJECT,  "subject" );
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse( "file:///mnt/sdcard/a.jpg" ));
intent.setType( "image/*" );
intent.setType( "message/rfc882" );
Intent.createChooser(intent,  "Choose Email Client" );
startActivity(intent);
Intent intent =  new  Intent(Intent.ACTION_SEND);
String[] tos = {  "[email protected]"  };
String[] ccs = {  "[email protected]"  };
String[] bccs = { "[email protected]" };
intent.putExtra(Intent.EXTRA_EMAIL, tos);
intent.putExtra(Intent.EXTRA_CC, ccs);
intent.putExtra(Intent.EXTRA_BCC, bccs);
intent.putExtra(Intent.EXTRA_TEXT,  "body" );
intent.putExtra(Intent.EXTRA_SUBJECT,  "subject" );
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse( "file:///mnt/sdcard/a.jpg" ));
intent.setType( "image/*" );
intent.setType( "message/rfc882" );
Intent.createChooser(intent,  "Choose Email Client" );
startActivity(intent);

很简单，发送邮件中，有收件者，抄送者，密送者。 也就是分别通过 Intent.EXTRA_EMAIL, Intent.EXTRA_CC, Intent.EXTRA_BCC 来进行putExtra来设定的，而单个附件的发送，则使用Intent.EXTRA_STREAM来设置附件的地址Uri。 【方法3】使用SEND_MULTIPLE来进行多附件的发送 

Intent intent =  new  Intent(Intent.ACTION_SEND_MULTIPLE);
String[] tos = {  "[email protected]"  };
String[] ccs = {  "[email protected]"  };
intent.putExtra(Intent.EXTRA_EMAIL, tos);
intent.putExtra(Intent.EXTRA_CC, ccs);
intent.putExtra(Intent.EXTRA_TEXT,  "body" );
intent.putExtra(Intent.EXTRA_SUBJECT,  "subject" );
ArrayList imageUris =  new  ArrayList();
imageUris.add(Uri.parse( "file:///mnt/sdcard/a.jpg" ));
imageUris.add(Uri.parse( "file:///mnt/sdcard/b.jpg" ));
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUris);
intent.setType( "image/*" );
intent.setType( "message/rfc882" );
Intent.createChooser(intent,  "Choose Email Client" );
startActivity(intent);
Intent intent =  new  Intent(Intent.ACTION_SEND_MULTIPLE);
String[] tos = {  "[email protected]"  };
String[] ccs = {  "[email protected]"  };
intent.putExtra(Intent.EXTRA_EMAIL, tos);
intent.putExtra(Intent.EXTRA_CC, ccs);
intent.putExtra(Intent.EXTRA_TEXT,  "body" );
intent.putExtra(Intent.EXTRA_SUBJECT,  "subject" );
ArrayList imageUris =  new  ArrayList();
imageUris.add(Uri.parse( "file:///mnt/sdcard/a.jpg" ));
imageUris.add(Uri.parse( "file:///mnt/sdcard/b.jpg" ));
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUris);
intent.setType( "image/*" );
intent.setType( "message/rfc882" );
Intent.createChooser(intent,  "Choose Email Client" );
startActivity(intent);
