IAPMiniProgram SDK provides the ability to customize the style of the back button in the title bar of the mini program, so that the Super App can use its own text or image to customize and render the back button of the mini programs accordingly. Follow this topic to realize this customization ability by implementing the specific interface of IAPMiniProgram SDK.

Procedures

Step 1. Implement the GriverBackButtonStyleExtension interface

Implement the GriverBackButtonStyleExtension interface and write code in the required methods according to your business logic.

Code sample as follows:

class CustomGriverBackButtonStyleExtensionImpl : GriverBackButtonStyleExtension {
    override fun getType(): String {
        return "icon"
    }

    override fun getContent(): String {
        return ""
    }

    override fun getIconDrawable(): Drawable {
        return context.getResources().getDrawable(R.drawable.custom_back)
    }
}

Step 2: Register the CustomGriverBackButtonStyleExtensionImpl class

Refer to the following sample code and call the registerExtension interface to register the CustomGriverBackButtonStyleExtensionImpl class after initializing the SDK.

IAPConnect.init(application, initConfig, object : InitCallback() {
    fun onSuccess() {
        //···
        Griver.registerExtension(
            GriverExtensionManifest(
                GriverBackButtonStyleExtension::class.java,
                CustomGriverBackButtonStyleExtensionImpl()
            )
        )
    }
})
