custom button drawable error

Question

I was following Custom Buttons to create custom buttons with different style.

In that link they have said to add Android.jar.

I hope when i create project itself it will be added (am i right?)

No resource found that matches the given name (at 'drawable' with value '@android:drawable/ grey_button_background_pressed_blue').

But i'm getting above error. When i followed that tutorial.

Wat error this could be?

Answer 1

First of all, what version of the SDK's jar did you use? That tutorial seems reeeeally old. I just checked my 2.3 SDK folder and there's no "grey" (or blue!) button drawables. Second, most widget images are not publicly exposed, so you wouldn't be able to do what you wanted to do anyway. In general, they way to create a custom button would be to go into the res folder of the platform folder in the SDK location (e.g. \android-sdk\platforms\android-10\data\res\) and copy over the assets that you want to modify into your drawables folder and customize them there.

In this case, you want to copy \drawable\btn_default.xml and all of the corresponding images, in \drawable-hdpi\btn_default_*.png and update them as you wish. Then to reference the copied button you would use the normal syntax: @drawable/btn_default (or whatever name you give it).
