[Android Apps and Games] StEVO_M:
I hope someone can help.

I have an application that I am building that currently has 3 main Layouts. All String-Arrays are in XML. First Screen Shows, Breakfast, Lunch & Dinner. Now depending on which Button is selected, Example "Lunch" a 2nd Layout comes up Showing the Lunch Menu items, such as Cheeseburger, Hamburger, Hot Dog, French Fries, Onion Rings... Let's say I select "Cheeseburger", the Item is Added to the 3rd Layout. When I click the Back button on the phone and select a new item such as "Onion Rings" that item replaces the Cheeseburger. I need it to ADD it to the List, not replace it. Can someone please tell me where my code is wrong?

Summary, I need the list to get appended with the items selected, not replaced by the selected item.

Here is my lunchActivity.java

package com.mycompany.foodmenu;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class lunchActivity extends Activity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.lunchmain);
final ListView lv=(ListView)findViewById(R.id.listView1);
ArrayAdapter<CharSequence> adapter=ArrayAdapter.createFromResource(this, R.array.lunch_menu,android.R.layout.simple_list_item_1);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
String item=lv.getItemAtPosition(arg2).toString();
String itemordered;
itemordered = item + " added to list";
Toast.makeText(getApplicationContext(), itemordered, Toast.LENGTH_LONG).show();

// Launching new Activity on selecting List Item
Intent i = new Intent(getApplicationContext(), ListItem.class);
// sending data to new activity
i.putExtra("item", item);
startActivity(i);
}
});
}
}

Here is the lunch.xml menu file that read by the lunchActivity to create the first ListView

<resources>

<string-array name="lunch_menu">
<item>Cheeseburger</item>
<item>Hamburger</item>
<item>Bacon Cheeseburger</item>
<item>Hot Dog</item>
<item>French Fries</item>
<item>Onion Rings</item>
</string-array>

</resources>

Here is the listItem.java

package com.mycompany.foodmenu;

import java.util.ArrayList;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class listItem extends Activity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.selecteditems);

Intent i = getIntent();

ArrayList<String> myNewList = new ArrayList<String>();
String item = i.getStringExtra("item");

myNewList.add(item);
ListView selecteditems = (ListView) findViewById(R.id.listitems);

ArrayAdapter<String> adapter = new ArrayAdapter<String>(ListItem.this, android.R.layout.simple_list_item_1, myNewList);
selecteditems.setAdapter(adapter);
// adapter.notifyDataSetChanged();

}
}

BTW. I have tried changing

myNewList.add(item);

to

myNewList.addAll(item);

and it just creates new problems. I have also tried adding

adapter.notifyDataSetChanged();

to the end and it makes no difference.

And here is the selectedItems.xml file that is suppose to get populated with the Selected Items from the Lunch Menu

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="@drawable/main_background"
android:paddingLeft="10.0dip"
android:paddingTop="0.0dip"
android:paddingRight="10.0dip"
android:paddingBottom="10.0dip"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<ListView
android:id="@+id/listitems"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="25dip"
android:textStyle="bold"
android:padding="10dip"
android:textColor="#ffffff"/>

</LinearLayout>

Any help would be greatly appreciated!!
