获取权限

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
   if (ContextCompat.checkSelfPermission(ContactsActivity.this, Manifest.permission.SEND_SMS) != PackageManager.PERMISSION_GRANTED) {
       ActivityCompat.requestPermissions(ContactsActivity.this, new String[]{Manifest.permission.SEND_SMS}, 1);
   } else {
       sendSMS(currentContact.getPhone());
   }
} else {
    sendSMS(currentContact.getPhone());
}

回调

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case 1:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                sendSMS(currentContact.getPhone());
            } else {
                Toast.makeText(this, getString(R.string.denied_permission), Toast.LENGTH_SHORT).show();
            }
            break;
        default:
    }
}

意图

Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.parse("smsto:"+phoneNumber));
intent.putExtra("sms_body", getString(R.string.sms));
startActivity(intent);
