这里是一个简单的基于Android Studio的登录注册界面的代码,包含了布局文件和Java代码。
1. 布局文件
activity_main.xml
```
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="16dp">
<EditText
android:id="@+id/editText_username"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/username" />
<EditText
android:id="@+id/editText_password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/password"
android:inputType="textPassword" />
<Button
android:id="@+id/button_login"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/login" />
<TextView
android:id="@+id/textView_register"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:text="@string/register"
android:textAlignment="center" />
</LinearLayout>
```
activity_register.xml
```
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="16dp">
<EditText
android:id="@+id/editText_register_username"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/username" />
<EditText
android:id="@+id/editText_register_password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/password"
android:inputType="textPassword" />
<Button
android:id="@+id/button_register"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/register" />
</LinearLayout>
```
2. Java代码
MainActivity.java
```
public class MainActivity extends AppCompatActivity {
private EditText editTextUsername;
private EditText editTextPassword;
private Button buttonLogin;
private TextView textViewRegister;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editTextUsername = findViewById(R.id.editText_username);
editTextPassword = findViewById(R.id.editText_password);
buttonLogin = findViewById(R.id.button_login);
textViewRegister = findViewById(R.id.textView_register);
buttonLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String username = editTextUsername.getText().toString().trim();
String password = editTextPassword.getText().toString().trim();
// TODO: 进行登录验证
}
});
textViewRegister.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, RegisterActivity.class);
startActivity(intent);
}
});
}
}
```
RegisterActivity.java
```
public class RegisterActivity extends AppCompatActivity {
private EditText editTextUsername;
private EditText editTextPassword;
private Button buttonRegister;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
editTextUsername = findViewById(R.id.editText_register_username);
editTextPassword = findViewById(R.id.editText_register_password);
buttonRegister = findViewById(R.id.button_register);
buttonRegister.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String username = editTextUsername.getText().toString().trim();
String password = editTextPassword.getText().toString().trim();
// TODO: 进行注册操作
}
});
}
}
```
以上代码仅提供了一个简单的登录注册界面,实际应用中还需要进行登录注册的逻辑处理。
