I have two buttons on my main Activity, which both should lead to another activity, but when I run the code it is showing an error.

MainActivity.java is this:

package com.assignment2.courier;

import static android.icu.lang.UCharacter.GraphemeClusterBreak.V;
import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;

public class MainActivity extends AppCompatActivity {

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

    public void second (View v){
        Intent i = new Intent(this, adelivery.class);
        startActivity(i);

    }
    }
}

This is the button code in activity_main.xml

 <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginStart="85dp"
        android:layout_marginBottom="234dp"
        android:onClick="second"
        android:text="Arrange Delivery"
        android:textSize="20sp" />

Error: Failed to compile values file

What is the problem here?

CodePudding user response：

The problem here is that the second function is inside the onCreate

You need to adapt the code as follows:

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}
public void second (View v){
    Intent i = new Intent(this, adelivery.class);
    startActivity(i);

  }
}

CodePudding user response：

You should move second method out of the onCreate method; this is the problem in your code.
