java - 单选按钮总是将默认值保存到 sqlite 中

Question

我的问题是，每当我检查数据库查看患者时，即使我检查女性，我也会看到性别是男性。 这是代码: fragment 病人.xml

请帮忙解决我的问题

Answer 1

解决方案:1

将 onCreateView() 的 view 对象声明为全局对象。

View view;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState){
view = inflater.inflate(R.layout.fragment_patient, parent, false);
    ...
}

并且您的radioG.getCheckedRadioButtonId()代码应位于onClick()

内

@Override
public void onClick(View v){

   int selectedId = radioG.getCheckedRadioButtonId();
   if(selectedId != -1) {    
        selectedRadioButton = (RadioButton)view.findViewById(selectedId);
   }

   boolean isInserted = myDB.insertData(editName.getText().toString() ,
   editFamilyname.getText().toString() ,
   editDob.getText().toString() ,
   ....
 }

解决方案:2

1. 创建两个RadioButton的对象

2. 将其与您在 onClick() 中选择的 RadioButton 进行比较

   @Override
   public void onClick(View v){
   
     int selectedId = radioG.getCheckedRadioButtonId();
     if(selectedId == radio1.getId()) {    
         selectedRadioButton = radio1;
     }
     else if(selectedId == radio2.getId()) {    
         selectedRadioButton = radio2;
     }
