It is a simple MVP android project to understand the basic concept on MVP architecture.
Android SDK v28 Latest Android Build Tools Android Support Repository
Simple login screen.
- Fake API call for delay
- View interaction with presenter
- Presenter interaction with View/Model
-
MainActivity implements MainActivityPresenter.View and overrides these methods.
public interface View { void updateLoginResponse(String response); void clearInputFeilds(); void showProgressBar(); void hideProgressBar(); } -
You can add any dummy credentials on login screen to proceed View communicates to presenter.
private MainActivityPresenter presenter = new MainActivityPresenter(this); presenter.loginAPICall("email", "password");after calling this there would be a dummy loader for fake API call (see MainActivityPresenter class) and return response to View.
mainActivityView.updateLoginResponse("Successfully logged in with these credentials: \n\n" + user.toString()); mainActivityView.clearInputFeilds(); mainActivityView.hideProgressBar();
//App's dependencies
implementation 'com.android.support:appcompat-v7:28.0.0'
public class MainActivityPresenter {
private User user;
private View mainActivityView;
public MainActivityPresenter(View mainActivityView) {
this.user = new User();
this.mainActivityView = mainActivityView;
}
public void loginAPICall(String email, String password) {
user.setEmail(email);
user.setPassword(password);
//Do API call here, I am adding dummy loader/for delay
mainActivityView.showProgressBar();
new CountDownTimer(3000, 1000) {
public void onTick(long millisUntilFinished) {
}
public void onFinish() {
mainActivityView.updateLoginResponse("Successfully logged in with these credentials: \n\n" + user.toString());
mainActivityView.clearInputFeilds();
mainActivityView.hideProgressBar();
}
}.start();
}
public interface View {
void updateLoginResponse(String response);
void clearInputFeilds();
void showProgressBar();
void hideProgressBar();
}
}
