Extensibility Theme Config

  • For customizing UI styles of elements, Host App can pass styles (plain JSON object) as an optional prop to root element <AdaptiveCards/>.

  • Currently below elements are supported in the theme config.

    • input
    • button
    • choice Set
    • date picker
    • time picker
  • Host app can provide platform-specific styles as mentioned in the below example. For the same styles across platforms, pass the styles without the platform.

    • Please note that if you want to provide platform-specific styles then you must provide different styles for all the platforms iOS, Android, and Windows explicitly. Please find the below example.
  • The color and textTransform property in the button will be applied to the button title. Remaining all styles in the button will apply to the React-Native button component.

Example

In this example, styles passed for element input are applied to all the platforms whereas for button platform-specific styles are applied.

    customThemeConfig = {
        input: {
            borderColor: "#000000",
            backgroundColor: "#F5F5F5",
            borderRadius: 4,
            borderWidth: 1,
        },
        button: {
            "ios": {
                color: 'white',
                backgroundColor: "#1D9BF6",
            },
            "android": {
                color: 'white',
                backgroundColor: "#1D9BF6",
            },
            "windows": {
                color: 'white',
                backgroundColor: "#1D9BF6",
            }
        }
    }
    
<AdaptiveCards themeConfig={customThemeConfig} payload={payload} />

Default Theme config

Currently, AdaptiveCards take the below theme config by default. But, the adaptive card developer can override below styles or add new styles using the custom theme config. Please note that the custom styles that are passing to the below elements should be supported in respective React-Native components.

defaultThemeConfig = {
    button: {
        ios: {
            borderRadius: 15,
            backgroundColor: "#1D9BF6",
            color: "white",
            textTransform: 'none'
        },
        android: {
            borderRadius: 15,
            backgroundColor: "#1D9BF6",
            color: "white",
            textTransform: undefined
        },
        windows: {
            borderRadius: 15,
            backgroundColor: "#1D9BF6",
            color: "white",
            textTransform: 'none'
        },
    },
    input: {
        borderColor: "#dcdcdc",
        backgroundColor: "white",
        borderRadius: 5,
        borderWidth: 1
    },
    inputDate: {
        width: '100%',
        height: 44,
        padding: 5,
        borderWidth: 1,
        backgroundColor: "white",
        borderColor: "lightgrey",
        borderRadius: 5,
    },
    inputTime: {
        width: '100%',
        height: 44,
        padding: 5,
        borderWidth: 1,
        backgroundColor: "white",
        borderColor: "lightgrey",
        borderRadius: 5,
    },
    radioButton: {
        width: 28,
        height: 28,
        tintColor :"#33cccc"
    },
    checkBox: {
        width: 28,
        height: 28,
        tintColor :"#668cff"
    },
    choiceSetTitle: {
        marginLeft: 8,
        flexShrink: 1
    },
}
