Question

我正在尝试在某些edittext中创建验证，我正在使用我在互联网上找到的示例，但是当我实现代码时，我的findViewById出错（在视图中无法应用于android.view.view。< / p>

public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
                         Bundle savedInstanceState) {

    final View view = inflater.inflate(R.layout.fragment_cadastro_contas_bancarias, container, false);

    View.OnClickListener listener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Fragment fragment = null;
            FragmentManager fragmentManager = getFragmentManager();
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

            switch (v.getId()) {
                case R.id.btn_cadastrar_conta:
                    registerAttemptWithRetrofit(1,
                            "3948",
                            "0",
                            "01089842",
                            "3",
                            1);

                    fragment = new ContasBancarias();

                default:
                    break;
            }

            fragmentManager.beginTransaction()
                    .replace(R.id.container, fragment)
                    .commit();

            View view1 = inflater.inflate(R.layout.fragment_cadastro_contas_bancarias, container, false);

            EditText agencia = (EditText) getView().findViewById(R.id.txt_agencia);

            if ("".equals(agencia.getText().toString().trim())) {
                Toast.makeText(getActivity(), "Campo Obrigatório", Toast.LENGTH_SHORT).show();
                return;

                //

    return view; }

你可以试试这个解决方案......

View view1 = inflater.inflate(R.layout.fragment_cadastro_contas_bancarias, container, false);

  EditText agencia = (EditText) view1 ().findViewById(R.id.txt_agencia);
