登录（第一个片段/标签）代码

Question

所以我有一个带标签活动的应用程序，如果点击按钮（btlink），我想更改第一个标签的布局：

登录（第一个片段/标签）代码

    public class login extends Fragment{
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.login, container, false);
        final EditText etUtilizador = (EditText) getView().findViewById(R.id.etUtilizador);
        final EditText etPassword = (EditText) getView().findViewById(R.id.etPassword);
        final Button btLogin = (Button) getView().findViewById(R.id.btLogin);
        Button btlink = (Button) getView().findViewById(R.id.btlink);
        btlink.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent registerIntent;
                registerIntent = new Intent(login.this, registar.class);
                login.this.startActivity(registerIntent);
            }
        });
        return rootView;
    }
}

但它显示错误：“registerIntent = new Intent（login.this，registar.class）;”

登录xml代码

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:ems="10"
    android:hint="Utilizador"
    android:inputType="textPersonName"
    android:textColor="@color/colorPrimaryDark" />

<EditText
    android:id="@+id/etPassword"
    android:layout_width="match_parent"

<TextView

    android:layout_marginTop="14dp"
    android:text="TextView"
    android:textColor="@color/colorPrimary"
    tools:text="Se ainda nao tem conta registe-se aqui:" />

我只希望代码在我点击按钮时将布局更改为：

registar.xml

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/constraintLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="@dimen/activity_vertical_margin"
    android:layout_marginEnd="@dimen/activity_horizontal_margin"
    android:layout_marginStart="@dimen/activity_horizontal_margin"
    android:layout_marginTop="@dimen/activity_vertical_margin">

</TextView>

<EditText
    android:id="@+id/etNome"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_below="@+id/section_label"
    android:layout_marginTop="70dp"
    android:ems="10"
    android:hint="Nome"
    android:inputType="textPersonName"
    android:textColor="@color/colorPrimaryDark" />

<EditText
    android:id="@+id/etEmail"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_below="@+id/etNome"
    android:layout_marginTop="30dp"
    android:ems="10"
    android:hint="Email"
    android:inputType="textEmailAddress"
    android:textColor="@color/colorPrimaryDark" />

<Button
    android:id="@+id/btPedido"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_below="@+id/etNumero"
    android:layout_marginTop="99dp"
    android:background="@color/colorAccent"
    android:elevation="0dp"
    android:text="Enviar pedido de registo"
    android:textAppearance="@style/BotaoRegisto" />

<EditText
    android:id="@+id/etNumero"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_below="@+id/etEmail"
    android:layout_marginTop="30dp"
    android:ems="10"
    android:hint="Nº faturação ou série"
    android:inputType="textPersonName"
    android:textColor="@color/colorPrimaryDark" />

如果有人能够我感激不尽。

Answer 1

首先设置 getView() ，而不是 final EditText etUtilizador = (EditText) rootView.findViewById(R.id.etUtilizador); final EditText etPassword = (EditText) rootView.findViewById(R.id.etPassword); final Button btLogin = (Button) rootView.findViewById(R.id.btLogin); Button btlink = (Button) rootView.findViewById(R.id.btlink); 。

new Intent(getActivity(), registar.class);

并使用getActivity()。

返回此片段当前与之关联的活动。

        Intent registerIntent;
        registerIntent = new Intent(getActivity(), registar.class);
        getActivity().startActivity(registerIntent);

Answer 2

变化

Intent registerIntent;
                registerIntent = new Intent(login.this, registar.class);
                login.this.startActivity(registerIntent);

要

 Intent   registerIntent = new Intent(getActivity(), registar.class);
        startActivity(registerIntent);

还需要改变

 final EditText etUtilizador = (EditText) rootView.findViewById(R.id.etUtilizador);
 final EditText etPassword = (EditText) rootView.findViewById(R.id.etPassword);
 final Button btLogin = (Button) rootView.findViewById(R.id.btLogin);

Answer 3

public class login extends Fragment{
Context context;    
@Override
onAttach(Activity activity){
context=(Context)activity;}
...
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
...
 registerIntent = new Intent(context, registar.class);
