android - 如何获取开关按钮的值并存储在数据库中？

Question

我正在制作一个注册页面，其中订阅短信选项带有开关切换按钮。如果客户切换该按钮，则值(真或假)应保存在数据库中。我无法找到解决方案

这是我的 Registration.class:

public class RegistrationForm extends AppCompatActivity {

    EditText fn,ln,mb,em,pw,cpw,dob,gen;
    Switch sw;
    RadioGroup male,feml;
    Switch swth;
    private ProgressDialog pDialog;
    String status="";


    public final Pattern EMAIL_ADDRESS_PATTERN = Pattern.compile(
            "[a-zA-Z0-9+._%-+]{1,256}" +
                    "@" +
                    "[a-zA-Z0-9][a-zA-Z0-9-]{0,64}" +
                    "(" +
                    "." +
                    "[a-zA-Z0-9][a-zA-Z0-9-]{0,25}" +
                    ")+"
    );


    private static String url_create_book = "http://cloud....com/broccoli/creatinfo.php";

    // JSON Node names

像那样处理你的开关按钮......

/////string that store switch state.. put this status while sending values to database
String status="false";  

//////set the switch to ON 
mySwitch.setChecked(false);

//////attach a listener to check for changes in state
mySwitch.setOnCheckedChangeListener(new OnCheckedChangeListener() { 
    @Override
    public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {

        if(isChecked){
           status="true"; //edit here
        }else{
           status="false"; //edit here
        }

     }
});

像这样发送到数据库..

params.add(new BasicNameValuePair("togglestatus",status));
