在SQLite数据库存储单选按钮值 [英] storing radio button value in sqlite database

问题描述

我有在这两个单选按钮单选按钮组。我想要得到的单选按钮的值，然后将其存储在database..how做呢？请帮助！我搜索了，但一切都是徒劳！
我想这code，但使用它后我的活动停止工作。

  RG =（RadioGroup中）findViewById（R.id.radioGroup2）;
如果（rg.getCheckedRadioButtonId（）！=  -  1）
    {
        INT ID = rg.getCheckedRadioButtonId（）;
        查看单选按钮= rg.findViewById（ID）;
        INT radioid = rg.indexOfChild（单选）
        单选按钮BTN =（单选）rg.getChildAt（radioid）;
        Father_spouse =（字符串）btn.getText（）;
    }
 

解决方案

1. 如果你想存储的文本标签的单选然后用这样的：

     //从radioGroup中选定的单选按钮
   INT selectedId = radioGroup.getCheckedRadioButtonId（）;如果（selectedId！= -1）{
      //找到返回ID的单选按钮
      selectedRadioButton =（单选）findViewById（selectedId）;   //你想要做什么用radioButtonText（它保存到数据库，你的情况）
      串radioButtonText = selectedRadioButton.getText（）;
   }
    




2. 如果你想保存一个布尔值等的 selectedId 测试你的单选按钮和保存0或1到你的数据库列（的两个单选按钮实例启用/禁用更新的）：

     //从radioGroup中选定的单选按钮
   INT selectedId = radioGroup.getCheckedRadioButtonId（）;
   布尔isAllowUpdate = FALSE;
   开关（selectedId）{
       案例R.id.radioAllowUpdate：isAllowUpdate = TRUE;打破;
       案例R.id.radioDisableUpdate：isAllowUpdate = FALSE;打破;
   }//保存到数据库
   如果（isAllowUpdate）
      //真正的==＆GT;保存值1
   其他
      //虚假==＆GT;保存0值

如果您应该控制选择的值，当它发送到数据库中，看到这个的教程

i have a radio group with two radio buttons in it. I want to get the value of the radio button and then store it in the database..how do i do that?? Pls help! I searched for it but all in vain! I tried this code but my activity stops working after using it

rg=(RadioGroup)findViewById(R.id.radioGroup2);
if(rg.getCheckedRadioButtonId()!=-1)
    {
        int id=rg.getCheckedRadioButtonId();
        View radioButton=rg.findViewById(id);
        int radioid=rg.indexOfChild(radioButton);
        RadioButton btn = (RadioButton) rg.getChildAt(radioid);
        Father_spouse=(String)btn.getText();
    }

解决方案

1. if you want to store the text label of your RadioButton then use this :

   // get selected radio button from radioGroup
   int selectedId = radioGroup.getCheckedRadioButtonId();
   
   if(selectedId != -1) {    
      // find the radiobutton by returned id
      selectedRadioButton = (RadioButton) findViewById(selectedId);
   
      // do what you want with radioButtonText (save it to database in your case)
      String radioButtonText = selectedRadioButton.getText();
   }
   

2. if you want to save a boolean value so test on the selectedId of your RadioButtons and save a 0 or 1 to your database column (Example of two radio buttons to enable/disable updates) :

   // get selected radio button from radioGroup
   int selectedId = radioGroup.getCheckedRadioButtonId();
   boolean isAllowUpdate = false;
   switch(selectedId) {
       case R.id.radioAllowUpdate : isAllowUpdate = true; break;
       case R.id.radioDisableUpdate : isAllowUpdate = false; break;
   }
   
   //save it to database 
   if(isAllowUpdate)
      // true ==> save 1 value
   else 
      // false ==> save 0 value
   

EDIT :

if you should control the selected value and when send it to database, see this tutorial
