How can i convert xml resources to int programatically in android?

Issue

I've a xml file in drawable which looks like :

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/green_button_unchecked" android:state_pressed="true"/>
<!--  pressed  -->
<item android:drawable="@color/green_button_unchecked" android:state_focused="true"/>
<!--  focused  -->
<item android:drawable="@color/green_button_unchecked" android:state_selected="true"/>
<!--  selected  -->
<item android:drawable="@color/gray_6"/>
<!--  default  -->
</selector>

I can use this in setBackgroundResource(drawable.xmlName);

As we know , setBackgroundResource() need resouceId of int type...

How can i use setBackgroundResource() by creating xml programatically if i am not allowed to use resources ??

I hope you understood my problem... Thankyou

Solution

I'm not sure how you're creating XML Programmatically, as if you want to create a Drawable you can do that without needing XML.

Any XML file has a name, and the IDE creates a generated class that contains all the IDs of the files.

If it's a drawable, it's R.drawable. For colors it's R.color. For Strings R.string.

So if you want to set background by resource, you just use setBackgroundResource(R.drawable.file_name)

If you don't want to use XML, you'll have to manually create the Drawable object, and use setBackground or setBackgroundDrawable instead. It is a big hassle, since there are many types of Drawables.

Vector Drawable, Gradient Drawable, Layered Drawable, Color Drawable, etc.

You'll have to figure out what you want and create it manually
