Question

I have got the code:

package com.finalyearproject.cookmefood;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.TextView;

public class SearchActivity extends Activity {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        ListView recipes = (ListView)findViewById(R.id.recipes);
    }
}

Which is giving me the error “id cannot be resolved”.

I have tried cleaning the project but that results in me creating errors in file which currently are fine.

My XML is:

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">
        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:padding="5dp" >
            <LinearLayout
                android:orientation="vertical"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
                android:padding="5dp">
                <ListView 
                    android:id="@+id/recipes"
                    android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:entries="@array.recipes"/>
            </LinearLayout>
        </FrameLayout>
    </LinearLayout>
</TabHost>

Any help would be appreciated, where can I go from here?

Answer 1

@array.recipes in the xml should be @array/recipes.
A simple typo like this will prevent your R class from building meaning you can’t find any id’s or other resources.
You should also make sure that you get the correct R as you are using both android.R and your R
