I want to set an image resource according to custom attribute of my
custom theme.
This is my attrs.xml file
<resources>
<declare-styleable name="PlayPauseButton">
<attr name="pauseImg" format="integer"/>
<attr name="playImg" format="integer"/>
</declare-styleable>
</resources>
Here I set values for the attributes in my theme in themes.xml:
<style name="MyTheme.Blue">
<item name="playImg">@drawable/play_button</item>
<item name="pauseImg">@drawable/pause_button</item>
</style>
The attribute has type integer, but when I try to get it in code, it
seems to be string:
TypedArray a =
getActivity().getTheme().obtainStyledAttributes(R.styleable.PlayPauseButton);
String path =
a.getString(R.styleable.PlayPauseButton_pauseImg); // returns "res/
drawable/pause_button.xml"
int id = a.getInteger(R.styleable.PlayPauseButton_pauseImg,0); //
"Cannot convert to integer" exception
Now I cannot get the drawable using this path. I tried:
int i = getResources().getIdentifier(path, "integer",
getActivity().getPackageName());
Drawable d = Drawable.createFromPath(path);
but both creates null objects.
My questions:
1. Is there any way how to create a drawable from the path "res/
drawable/pause_button.xml" so I can pass it to
playButton.setImageResource() or playButton.setImageDrawable().
2. Overall I think this is not the best way how to do it. The
attribute pauseImg has integer type. Why I get string? Is there any
way how to get the attribute value as resource id integer, ie.
identicaly to R.drawable.pause_button ?
Thank you very much for any help with this or for any ather way how to
do it. I am really stucked.
