How to Get String Array from Arrays.Xml File

How to get String Array from arrays.xml file

You can't initialize your testArray field this way, because the application resources still aren't ready.

Just change the code to:

package com.xtensivearts.episode.seven;

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class Episode7 extends ListActivity {
    String[] mTestArray;

    /** Called when the activity is first created. */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Create an ArrayAdapter that will contain all list items
        ArrayAdapter<String> adapter;

        mTestArray = getResources().getStringArray(R.array.testArray);    

        /* Assign the name array to that adapter and 
        also choose a simple layout for the list items */ 
        adapter = new ArrayAdapter<String>(
            this,
            android.R.layout.simple_list_item_1,
            mTestArray);

        // Assign the adapter to this ListActivity
        setListAdapter(adapter);
    }
}

Android: How do you access a string-array from strings.xml in a custom class?

Pass the context to the constructor of custom class and use the same

new CustomClass(ActivityName.this);

Then

Context mContext;
public CustomClass(Context context)
{
    mContext = context;
}

use the context

String[] foo_array = mContext.getResources().getStringArray(R.array.foo_array);

Also keep in mind

Do not keep long-lived references to a context-activity (a reference to an activity should have the same life cycle as the activity itself)

Also check this

android getResources() from non-Activity class

Edit:

Change this

public class CustomClass(Context context) 
{
}

To

public class CustomClass
{
   Context mContext;
   public CustomClass(Context context) // constructor 
   {
    mContext = context;
   }
}

            holder.text.setText("Title " + data[position]);

            return vi;
        }
    }

            public TextView text;

        }

How Do I call String-array value in xml layout

Just to giva a full answer to your problem:

There is no way of accessing an array directly, but you could do something like this:

<string name="books_titles_en_1">Smoking Effeccts on Your Body</string>
<string name="books_titles_en_2">Smoking - effects on your body</string>
<string name="books_titles_en_3">How Tobacco Smoke Causes Disease</string>
<string name="books_titles_en_4">patterns of use, health effects, use in smoking cessation and regulatory issues</string>
<string-array name="books_titles_en">
    <item>@string/books_titles_en_1</item>
    <item>@string/books_titles_en_2</item>
    <item>@string/books_titles_en_3</item>
    <item>@string/books_titles_en_4</item>
</string-array>

and then:

<TextView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:paddingLeft="@dimen/frag_1_text_pad"
            android:textSize="@dimen/frag_1_text_size"
            android:paddingRight="@dimen/frg_1_text_right_pad"
            android:id="@+id/book_link0"
            android:text="@string/book_title_en_1"/>

So you basically reference the neccessary strings directly, that are referenced in your string array. ;)
