如果您在短信读取代码之前调用requestSmsPermission()，则需要获得所有必要的许可

private void requestSmsPermission() {
    String permission = Manifest.permission.READ_SMS;
    int grant = ContextCompat.checkSelfPermission(this, permission);
    if (grant != PackageManager.PERMISSION_GRANTED) {
        String[] permission_list = new String[1];
        permission_list[0] = permission;
        ActivityCompat.requestPermissions(this, permission_list, 1);
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    if (requestCode == 1) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {                                      
            Toast.makeText(AccountClass.this,"permission granted", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(AccountClass.this,"permission not granted", Toast.LENGTH_SHORT).show();
        }
    }

}
