1. 创建Model层:创建一个接口用于定义网络请求的方法,例如:
```
public interface LoginModel {
void login(String username, String password, String code, Callback callback);
}
```
2. 创建Presenter层:创建一个Presenter类,用于处理业务逻辑和网络请求,例如:
```
public class LoginPresenter {
private LoginModel loginModel;
public LoginPresenter(LoginModel loginModel) {
this.loginModel = loginModel;
}
public void login(String username, String password, String code) {
loginModel.login(username, password, code, new Callback() {
@Override
public void onResponse(Call call, Response response) throws IOException {
// 处理网络请求成功的逻辑
}
@Override
public void onFailure(Call call, IOException e) {
// 处理网络请求失败的逻辑
}
});
}
}
```
3. 创建View层:创建一个Activity或Fragment作为View层,用于处理用户界面和Presenter层的交互,例如:
```
public class LoginActivity extends AppCompatActivity implements View.OnClickListener {
private EditText etUsername;
private EditText etPassword;
private EditText etCode;
private ImageView ivCode;
private Button btnLogin;
private LoginPresenter loginPresenter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
etUsername = findViewById(R.id.et_username);
etPassword = findViewById(R.id.et_password);
etCode = findViewById(R.id.et_code);
ivCode = findViewById(R.id.iv_code);
btnLogin = findViewById(R.id.btn_login);
loginPresenter = new LoginPresenter(new LoginModelImpl());
ivCode.setOnClickListener(this);
btnLogin.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.iv_code:
// 更新验证码图片
break;
case R.id.btn_login:
String username = etUsername.getText().toString().trim();
String password = etPassword.getText().toString().trim();
String code = etCode.getText().toString().trim();
loginPresenter.login(username, password, code);
break;
}
}
}
```
4. 创建Model层实现类:创建一个实现了LoginModel接口的类,用于实现网络请求的具体逻辑,例如:
```
public class LoginModelImpl implements LoginModel {
@Override
public void login(String username, String password, String code, Callback callback) {
OkHttpClient client = new OkHttpClient();
RequestBody requestBody = new FormBody.Builder()
.add("username", username)
.add("password", password)
.add("code", code)
.build();
Request request = new Request.Builder()
.url("http://example.com/login")
.post(requestBody)
.build();
Call call = client.newCall(request);
call.enqueue(callback);
}
}
```
5. 在AndroidManifest.xml文件中添加网络访问权限:
```
<uses-permission android:name="android.permission.INTERNET"/>
```
6. 编译运行程序,在登录界面输入账号、密码和验证码,点击登录按钮,Presenter层会发起网络请求,Model层实现类会执行具体的网络请求逻辑,请求结果会回调到Presenter层的Callback中,在Callback中处理网络请求的成功或失败逻辑。在View层中更新界面的显示效果。
