Question

我有以下复选框和 TextInputLayouts 列表

TextInputLayout 的显示和隐藏基于是否单击了 cirtan 复选框。这是处理该问题的代码：

fun onCheckboxClicked(view: View) {
    if (view is CheckBox) {
        val checked: Boolean = view.isChecked
        val test = view.id
        when (view.id) {
            R.id.hasLeassionCheckBox->{
                if(checked){
                    lesionCommentsField.visibility = View.VISIBLE
                }
                else{
                    lesionCommentsField.visibility = View.GONE
                }
            }
            R.id.tobacoCheckBox->{
                if(checked){
                    yearsOfTobacoUseField.visibility = View.VISIBLE
                }
                else{
                    yearsOfTobacoUseField.visibility = View.GONE
                }
            }
            R.id.alcoholCheckbox->{
                if(checked){
                    drinksPerWeek.visibility = View.VISIBLE
                    alcoholYearsField.visibility = View.VISIBLE
                    Log.i("PATIENT ACTIVITY", "DRINKS PER WEEK VIEW: ${drinksPerWeek.visibility}")
                }
                else{
                    drinksPerWeek.visibility = View.GONE
                    alcoholYearsField.visibility = View.GONE
                }
            }
            R.id.cancerCheckBox-> {
                if (checked) {
                    cancerYearsField.visibility = View.VISIBLE
                    cancerCountField.visibility = View.VISIBLE
                } else {
                    cancerYearsField.visibility = View.GONE
                    cancerCountField.visibility = View.GONE
                }
            }
            R.id.oralPainCheckBox->{
                if(checked){
                    yearsOfOralPainField.visibility = View.VISIBLE
                    painSeverityField.visibility = View.VISIBLE
                }
                else{
                    yearsOfOralPainField.visibility = View.GONE
                    painSeverityField.visibility = View.GONE
                }
            }
        }
    }
}

这应该工作的方式是当用户选择某些复选框时显示某些 TextInputLayouts。例如：如果用户选择 has_lession 复选框，则应该显示 lesionCommentsField TextInputLayout。

用户第一次填写此表单时，此代码运行良好。对于所有复选框和 TextInputLayouts。用户第二次使用此表单时，上次单击的复选框不会使其相应的 TextInputLayouts 可见。例如：如果用户在上次使用表单时选择了 has_lession 复选框，而这次在 lesionCommentsField 周围选择了相同的复选框。

之前使用表单时未点击的其他复选框工作正常，只有之前使用表单时使用的复选框出现问题。

重启应用程序后问题消失。

我已经调试并检查了这些字段是否设置为可见，只是它们没有显示在屏幕上。

我在一个片段中有这个，复选框代码在它的父 activity 中。不确定这是否有所作为。

我将如何调试和解决这个问题？

Answer 1

编辑我的答案，我刚刚了解到可以同时看到多个视图。

为什么不为所有复选框单独编写此 onCheckChange 方法而不是 onClick？

hasLeassionCheckBox.setOnCheckedChangeListener { compoundButton, isChecked ->
            if (isChecked) {
                lesionCommentsField.visibility = View.VISIBLE
            } else {
                lesionCommentsField.visibility = View.GONE
            }
        }

设置 View.VISIBLE 并不总能让我的观点可见

Setting View.VISIBLE does not always make my views visible
