调用发送短信程序的Uri

Uri smsToUri = Uri.parse("smsto:" + mContact.getNumber());
Intent intent = new Intent(Intent.ACTION_SENDTO, smsToUri);
intent.putExtra("sms_body", "The SMS text"); 

mContext.startActivity(intent);

或者：

Uri smsToUri = Uri.fromParts("smsto", mContact.getNumber(), null);
Intent intent = new Intent(Intent.ACTION_SENDTO, smsToUri);
intent.putExtra("sms_body", "The SMS text"); 
startActivity(intent);
