You are using android.R.layout.simple_list_item_1 as the layout of the item in the ListView. If you want to customize the layout of the items, follow these steps:

Step 1) Create a custom XML layout (simple_list_item_custom.xml) as follows:

<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:id="@android:id/text1" 
    style="?android:attr/listItemFirstLineStyle" 
    android:paddingTop="2dip"  
    android:paddingBottom="3dip"
    android:textColor="#FF0000"/>

In this above layout, add XML attributes to change the font size, color etc. (Just like I added android:textColor="#FF0000" to make the color red.

Step 2) Init the adapter with your custom layout:

adapter =new ArrayAdapter<String>(this, R.layout.simple_list_item_custom, getResources().getStringArray(R.array.myArray));

Everything else remains the same..

Wow! it would be good if you explain _"this is not working"_? Crashing or what? – Amulya Khare Dec 15 '13 at 04:57
dude it's just not working , nothing happened to color – Anonymous Dec 15 '13 at 05:04
i mean i have already specified the location of my arrays. so do i have to remove it ?? – Anonymous Dec 15 '13 at 05:06
remove `style="?android:attr/listItemFirstLineStyle"` and try again with my answer.. the color should change.. if not i will verify some things.. – Amulya Khare Dec 15 '13 at 05:07
You mean to say that you replaced `android.R.layout.simple_list_item_1` with `R.layout.simple_list_item_custom` in your adapter initialization. And the list still loads as before and the color is not red? – Amulya Khare Dec 15 '13 at 05:13
i'm using "myArray" at two places – Anonymous Dec 15 '13 at 05:15
I am just talking about this line `adapter =new ArrayAdapter(this,android.R.layout.simple_list_item_1, getResources().getStringArray(R.array.myArray));` forget about myArray.. its nothing to do with that.. – Amulya Khare Dec 15 '13 at 05:17
if i replace , it will remove my arrays ,(which it did ) – Anonymous Dec 15 '13 at 05:18
