试试这个：

Intent emailintent = new Intent(android.content.Intent.ACTION_SEND); 
emailintent.setType("image/jpeg"); 
emailintent.putExtra(android.content.Intent.EXTRA_TEXT, 
"email body here"); 
emailintent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] 
    {"[email protected]"}); 
emailintent.putExtra(android.content.Intent.EXTRA_SUBJECT, 
"Subject here"); 
String filName="file:///sdcard/photos/estdemo.jpg"; 
emailintent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:/"+ filName)); 
this.startActivity(emailintent);

尝试下面的代码，

Intent i = new Intent(Intent.ACTION_SEND);

startActivity(i);

使用下面的代码来发送邮件

Intent sharingIntent = new Intent(Intent.ACTION_SEND); 
sharingIntent.setType("vnd.android.cursor.dir/email"); 
String to[] = "[email protected]"; 
sharingIntent.putExtra(Intent.EXTRA_EMAIL, to); 
sharingIntent.putExtra(Intent.EXTRA_STREAM,filePath); 
sharingIntent.putExtra(Intent.EXTRA_SUBJECT,"subject"); 
startActivity(Intent.createChooser(sharingIntent, "Send email"));
