StringBuffer() strImages开发者_如何转开发 = new StringBuffer();
strImages.append(strImg1_pref);
strImages.append("\n\n");
strImages.append(strImg2_pref);
strImages.append("\n\n");
strImages.append(strImg3_pref);
strImages.append("\n\n");
strImages.append(strImg4_pref);
strImages.append("\n\n");
String strTemp = strImages.toString();

startActivity(Intent.createChooser(new Intent(Intent.ACTION_SEND).setType("image/jpeg").setType("message/rfc822")
   .putExtra(Intent.EXTRA_EMAIL, emails)
   .putExtra(Intent.EXTRA_SUBJECT, subject)
   .putExtra(Intent.EXTRA_TEXT, strDetails).putExtra(Intent.EXTRA_STREAM, Uri.parse(strTemp)), "Send your email in:"));
