Registration.java

package kudan.eu.armcqevaluator;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
public class Registration extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.registration);
    }
}

Answer 1

you need to add onClickListener method to your button.

registor.setOnClickListener(this);

Then only the onclickListener will work for that button.

Also check for activity entry in manifest file for registration activity.

Answer 2

You can't call override methods from XML onClick. Implement a public method and do your functionality on that method.

on XML file:

android:onClick="RedirectRegisterMethod"/>

on java file:

public void RedirectRegisterMethod(View v) {
// do your functionality here
}
