Android: Use default highlight colors in a custom button

问题

I want to use a Button in my android app but I want to customize how it looks. However, I want the highlight and selected colors of the button to be the same as the default colors (i.e. the dark and light orange gradients, or whatever the theme color supplies).

Is there anyway to get the default highlight/selected drawables and to use that as the fill for my buttons on the selected and highlighted states?

Thanks!

回答1:

You are asking for two different things, do you want the drawables or the colorcode?

Anyway, you can find the name of the drawables here: http://androiddrawableexplorer.appspot.com/ I don't know if you can use them directly from your app or if you have to save them to your drawables folder first, but you can find them in your sdk. If you want the colorcodes, use gimp to extract them from the pictures.

It seems that you can use a selector as drawable inside a selector! (You can or should not use @android:drawable/btn_default_selected, because it is private) This meens that you can write your own selecter and use the whole default android selector for the items you want the default behavior for.

I used this selector

<selector xmlns:android="http://schemas.android.com/apk/res/android" >

    <item android:drawable="@android:drawable/btn_default" android:state_pressed="true"/>

</selector>

And added it to as background to a linear layout. I don't know why, but this messed up the padding/margin as well, thats why i set them to 0.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/background_linear_layout_button"
    android:padding="0dp"
    android:layout_margin="0dp"
    android:orientation="vertical" >

    <!-- YOUR LAYOUT THAT ACTS LIKE A BUTTON -->
</LinearLayout>

The Result is that you have the parent background color in the unpressed state and the android background color for the pressed state.
