问题描述

我有一个单选组,其中有两个单选按钮.我想获取单选按钮的值,然后将其存储在数据库中..我该怎么做?请帮忙!我搜索了它,但一切都是徒劳的!我尝试了这段代码,但我的活动在使用后停止工作

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();
    }

推荐答案

  1. 如果您想存储 RadioButton 的文本标签,请使用:

  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();
}

  • 如果您想保存布尔值,请测试 RadioButtonsselectedId 并将 0 或 1 保存到数据库列(启用/禁用更新的两个单选按钮示例):

  • 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
    

  • 如果您应该控制所选值并将其发送到数据库,请参阅此 教程
