activity_login.xml :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:padding="30dp"
    android:layout_height="match_parent">

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <Button
       android:gravity="center"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Submit"
        />

</LinearLayout>

To achieve MVP Pattern, we need 2 interface and 1 class and 1 Activity .

Login Activity
LoginView   ->  (Interface )
LoginPresenter   -> (Interface ) 
LoginPresenterImplemetation  -> ( class)

• Login Activity implements LoginView .
• LoginPresenterImplemetation implements LoginPresenter

LoginActivity

    

public class LoginActivity extends AppCompatActivity implements LoginView {




    @Override

    protected void onCreate(@Nullable Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_login);

    }

}

 

LoginView

package com.stacklearning.androidmvp.login;




/**

public interface LoginView {

}




 

LoginPresenter

package com.stacklearning.androidmvp.login;




/**

public interface LoginPresenter {

}
