How to Locate Default Android Button Styles and Color Codes?

Question

How can I find the default Android button styles and their corresponding hexadecimal color codes?

<style name="Widget.Button">
    <item name="android:background">@android:drawable/btn_default</item>
    <item name="android:textColor">@android:color/white</item>
</style>

Answer

To locate the default Android button styles and color codes, you need to explore the Android SDK directory and understand the structure of Android's resource files. The default styles for buttons are defined in 'styles.xml' and the colors can be located in 'colors.xml'.

<style name="Widget.Button">
    <item name="android:background">@android:drawable/btn_default</item>
    <item name="android:textColor">@android:color/white</item>
</style>

Causes

  • Misunderstanding of where default styles are defined within the Android SDK.
  • Inability to navigate the Android SDK folders effectively.

Solutions

  • Navigate to the SDK installation folder and locate styles.xml at: <installation_folder>/android-sdk/platforms/android-<version>/data/res/values/styles.xml.
  • Look for button styles under the Widget.Button definition.
  • To understand color definitions, check the drawable resources located at: <installation_folder>/android-sdk/platforms/android-<version>/data/res/drawable/.

Common Mistakes

Mistake: Not checking the correct version of the SDK folder.

Solution: Confirm you are looking at the correct version of the Android SDK that you are currently developing against.

Mistake: Overlooking drawable resources when searching for color codes.

Solution: Ensure to check the drawable resources as they contain states and colors used for buttons.
