"How to pass a parameter into a drawable" or "Create button with gradient and changeable image"
I have a custom drawable in my android project that should be the background of a button. But each button should also support an icon AND a text.
What I tried so far is the following:
I have a drawable called "btn_background.xml"
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list >
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#ff0000"
android:endColor="#ee1111"
android:type="linear"
android:angle="90"/>
<stroke android:color="#ff0000"
android:width="1dip"/>
<size android:width="80dip"
android:height="40dip" />
</shape>
</item>
<item android:drawable="@drawable/btn_search"/>
</layer-list>
</item>
And in my layout file i use that like this:
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:background="@drawable/btn_background"
android:textColor="#ffffff"/>
This is getting me somewhere close... but there are two problems: * The image is stretched across the whole button * I can't just change the image in the layout file... so i would have to make a seperate btn_whatever.xml file for each icon?!?
The other solution that I tried was to use an ImageButton instead of an Button and set the background to my btn_b开发者_如何学Goackground.xml .... this would make me able to select the image in the layout file... but then i can't give it a text....
I would be happy to hear about your solutions for my problem :)
Thanks a lot!
Try to use android:drawableLeft
(or similar Top
, Right
, Bottom
) attribute.
