如何使用流绑定

Question

我尝试处理按钮上的点击并将操作发送到 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) }
    }
}

只有来自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并为一个？可能这就是问题所在，有 3 个动作流可以查看模型

Answer 1

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)
}
