反射创建ViewBinding

activity中kotlin 使用

open fun createViewBinding(inflater: LayoutInflater):B? {

        try {

        val genericSuperclass =javaClass.genericSuperclass

                if (genericSuperclassis ParameterizedType) {

                        val types =genericSuperclass.actualTypeArguments

                        val tClass = types[0]as Class<*>

                        val inflate = tClass.getDeclaredMethod("inflate", LayoutInflater::class.java)

                        return inflate.invoke(null, inflater)as B

                }

        }catch (e: Exception) {

            e.printStackTrace()

            //LogUtils.e("createViewBinding err " + e.message)

        }

        return null

}

RecyclerView的adapter中使用

    @Override

    protected H onCreateViewBinding(LayoutInflater inflater, ViewGroup parent,int viewType) {

                Type genericSuperclass = getClass().getGenericSuperclass();

                try {

                        if (genericSuperclassinstanceof ParameterizedType) {

                                Type[] types = ((ParameterizedType) genericSuperclass).getActualTypeArguments();

                                Class tClass = (Class) types[1];

                                Method method = tClass.getDeclaredMethod("inflate", LayoutInflater.class,                                                                                   ViewGroup.class,boolean.class);

                                Object invoke = method.invoke(null, inflater, parent,false);

                                return (H)invoke;

                        }

                }catch (Exception e) {

                        e.printStackTrace();

                }

                return null;

        }
