如何使用流绑定

如何解决如何使用流绑定

我尝试处理按钮上的点击并将动作发送到 viewmodel

private fun subscribeUI() {
    lifecycleScope.launch {
            binding.loginButton
                .clicks()
                .onEach { }
                .map { Action.WelcomeAction.SelectLogin }
                .collect { viewmodel.actions.offer(it) }
            binding.homeButton
                .clicks()
                .onEach { }
                .map { Action.WelcomeAction.SelectHome }
                .collect { viewmodel.actions.offer(it) }
            binding.registerButton
                .clicks()
                .onEach {}
                .map { Action.WelcomeAction.SelectRegister }
                .collect { viewmodel.actions.offer(it) }
    }
}

只有登录按钮的操作才会出现在我的视图模型中。如何将这三个流程合二为一？可能这就是有 3 个动作流来查看模型的问题

解决方法

private fun subscribeUI() {
    merge(
        binding.loginButton.clicks().map { Action.WelcomeAction.SelectLogin },binding.homeButton.clicks().map { Action.WelcomeAction.SelectHome },binding.registerButton.clicks().map { Action.WelcomeAction.SelectRegister }
    )
        .onEach { viewModel.actions.offer(it) }
        .launchIn(lifecycleScope)
}
