Question

我知道这已被问了很多，但我仍然无法找到解决方法。当我选择另一个单选按钮时，这些单选按钮不会清除。我不希望他们返回或显示值，而是设置值。

所有三个单选按钮都在标识为radioGroup

的广播组内

请帮忙。谢谢:)）

public void onRadioButtonClicked(View view) {
    boolean checked = ((RadioButton) view).isChecked();

    switch(view.getId()) {
        case R.id.radioButton_plumber:
            if(checked) {
                internalWorkerType = "Plumbers";
                dbRef = db.getReference(Common.user_workers_table).child(internalWorkerType);
            }
            break;
        case R.id.radioButton_carpenter:
            if(checked) {
                internalWorkerType = "Carpenters";
                dbRef = db.getReference(Common.user_workers_table).child(internalWorkerType);
            }
            break;
        case R.id.radioButton_electrician:
            if(checked) {
                internalWorkerType = "Electricians";
                dbRef = db.getReference(Common.user_workers_table).child(internalWorkerType);
            }
            break;
    }

Answer 1

RadioButtons必须是RadioGroup的直接孩子，删除constraintLayout才能生效

Answer 2

尝试将text = "" for a in response.css("div.article *::text").extract() text += a.strip()保留在外面。

ConstraintLayout

如果您想使用ConstraintLayout来管理RadioButton小部件的布局，请访问https://github.com/samlu/ConstraintRadioGroup

blRadioGroup小部件可以帮助管理ConstraintLayout中选中的RadioButton的更改。

RadioButton没有取消选中
