Android Custom Capabilities

Last updated: 2023-06-13 11:27:15
    This document introduces the custom capabilities of the eKYC SDK (global edition).

    I. Custom UI

    Customizing layout

    The eKYC SDK supports custom UI by using AuthUiConfig (see the API description document) or passing in Layout resId.
    The usage is as follows:
    AuthUiConfig authConfig = new AuthUiConfig();
    authUiConfig.setAuthLayoutResId(R.layout.demo_huiyan_fragment_authing);
    authUiConfig.setAuthCircleCorrectColor(resources.getColor(R.color.demo_blue));
    huiYanOsConfig.setAuthUiConfig(authUiConfig);
    The following figure shows the default layout:
    
    
    
    The default layout is as shown above, where the positions of all controls can be adjusted by modifying the Layout.xml file. For more information, see the demo's demo_huiyan_fragment_authing.xml file.
    Note:
    The View type and the corresponding android:id in demo_huiyan_fragment_authing.xml are involved in UI event binding, so do not modify them.
    The default layout provided here is as follows:
    <?xml version="1.0" encoding="utf-8"?>

    Binding events for custom layout

    The previous section describes how to customize the UI layout. This section describes how to bind events to the controls added to the custom UI layout to meet your specific needs.
    When the liveness detection and face comparison UI is created, onMainViewCreate(View authView) of HuiYanAuthEventCallBack will be called. When the liveness detection and face comparison UI is to be terminated, the onMainViewDestroy() method will be called back, and you can customize the processing logic in the corresponding lifecycle.
    // Set a callback listener for key events in FaceID
    HuiYanOsApi.setAuthEventCallBack(new HuiYanAuthEventCallBack() {
    @Override
    public void onAuthTipsEvent(HuiYanAuthTipsEvent tipsEvent) {
    Log.e(TAG, "current is : " + tipsEvent);
    }
    
    @Override
    public void onMainViewCreate(View authView) {
    if (authView == null) {
    return;
    }
    // Get the added controls and register custom events
    Button findBtn = authView.findViewById(R.id.add_view_offer_button);
    if (findBtn != null) {
    findBtn.setOnClickListener(view -> {
    Log.e(TAG, "click test button!");
    });
    }
    }
    
    @Override
    public void onMainViewDestroy() {
    Log.e(TAG, "onMainViewDestroy");
    }
    });
    Based on the callback of onMainViewCreate and the callback method of onMainViewDestroy, you can bind events to the added UI controls to achieve the desired effect.

    II. Custom Prompt and Language

    Customizing prompt

    If you want to modify a prompt or add a language file, follow the instructions below. The eKYC SDK provides a translation file hy_customer_string.xml , which contains all the configuration text that can be modified.
    1. Open the project in the main module (which integrates the eKYC SDK).
    2. Add the hy_customer_string.xml file to the corresponding language folder.
    3. Modify the text content that needs to be customized.
    4. After being packaged, the modified content will automatically overwrite the original content.
    
    
    

    Adding a language

    To add a language, perform the following steps:
    1. Add the corresponding language folder to the project in the main module (which integrates the eKYC SDK).
    2. Copy the hy_customer_string.xml file to the language folder and modify the value content.
    
    
    
    3. Specify the target language code in the code (with Thai as an example).
    huiYanOsConfig.setLanguageStyle(LanguageStyle.CUSTOMIZE_LANGUAGE);
    huiYanOsConfig.setLanguageCode("th-TH");
