How to load array from xml in Android?

How to load array from xml in Android?
These are the code I found in Android framework/base/core.

Here is the example.

First, the array.xml is below:

<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2">
    <array name="lockscreen_targets_when_silent">
        <item>@drawable/ima_btn</item>
        <item>@drawable/images</item>
    </array>
</resources>

Then, you can use these code to get the items from the array.
The parameter of the obtainTypedArray() is the array which you want to get the item from.

TypedArray typAry = getResources().obtainTypedArray(
        R.array.lockscreen_targets_when_silent);
        for (int i = 0; i < typAry.length(); i++) {
            TypedValue value = typAry.peekValue(i);
            Log.d(TAG, "get resourceId: " + value.resourceId + ", 
            get ResourceName: " + getResources().getResourceName(value.resourceId));
