Hello,

here

I uploaded my Android project made in Eclipse. The idea is that i have a service, which computes the sum of two random numbers. But when i press the OK Button, i don't see the result in that edit box... why? What i'm doing wrong? Please help

Thanks!

EDIT: The code:

//service class

 package service;

import java.util.Random;
import com.android.AplicatieSuma;
import android.widget.EditText;
import android.widget.TextView;

public class ServiciuSuma 
{   
    public ServiciuSuma() { }

    public int CalculateSum()
    {
        Random generator=new Random();
        int n=generator.nextInt();
        int m=generator.nextInt();
        return n+m;
    }
}

The Application class:

package com.android;
import android.app.*;
import service.*;

public class ApplicationSum extends Application {
    public ServiciuSuma service = new ServiciuSuma();
}

and the main Activity class:

package com.android;

import com.android.R;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.graphics.PorterDuffColorFilter;
import android.graphics.drawable.Drawable;
import android.graphics.PorterDuff;
import android.os.Bundle;
import android.provider.Settings;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.EditText;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;

public class Activitate extends Activity  {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);  

        View btn_ok = findViewById(R.id.btn_ok);
        btn_ok.setOnClickListener(new OnClickListener() 
            {
                public void onClick(View v) 
                {
                    CalculeazaSuma();                   
                }
            });
    }


    private void CalculeazaSuma()
    {
        AplicatieSuma appState = ((AplicatieSuma)this.getApplication());
        EditText txt_amount = (EditText)findViewById(R.id.txt_amount);
        txt_amount.setText(appState.service.CalculateSum());
        //BindData();
    }
}

So that edit text does not show the sum of the random generated numbers, by the service. What's wrong?

Thanks
