How to get arrays in android arrays.xml according value

Question

In android arrays.xml, I can define arrays like below,

<string-array name="feed_icons">

    <item value="0">@drawable/latest</item>

    <item value="1">@drawable/video</item>

    <item value="2">@drawable/world</item>

    <item value="3">@drawable/sports</item>

    <item value="4">@drawable/arts</item>

    <item value="5">@drawable/dining</item>

</string-array>

I wonder how to get the drawable according the value? Is three any function? I just kown that,

String[] iconArrays = getResource().getStringArrays(R.arrays.feed_icons);

but it's not my desired.

you have given value as 0 to n so you can get appropriate drawable from String[] as position wise which indirectly value. — Hareshkumar Chhelana

You could save the drawable names in an array like:

<string-array name="feed_icons">
    <item value="0">latest</item>
    <item value="1">video</item>
</string-array>

Then fetch the drawable:

String[] iconArrays = getResources().getStringArray(R.arrays.feed_icons);

// Get specific drawable resource id
int drawableResId = this.getResources().getIdentifier(iconArrays[0], "drawable", getPackageName());

// Fetch drawable by resource id
Drawable yourDrawable = getResources().getDrawable(drawableResId);

// Use drawable
imageView.setDrawable(yourDrawable);
