如何获取赋予ImageView的可绘制对象的资源ID

Question

I need to get the id of the drawable I assigned to an ImageView by xml.

I have different buttons that need to change look when pressed, so I wanted to write just one method for all of them putting into 2 arrays the NOT_TOUCHED drawable ids and the TOUCHED drawable ids and so on...

How can I do this?

If you want to change the image view to different state when image view touch or not touch, you better use drawable selector resource. Create a drawable/background.xml like following, then set as background of your image view.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@drawable/focused_image" android:state_focused="true"></item>
<item android:drawable="@drawable/selected_image" android:state_selected="true"></item>
<item android:drawable="@drawable/normal_image"></item>

</selector>
