Java 选中时如何使用截击发送单选按钮/单选组的数据

我正在为我正在创建的应用程序制作一个注册表单。它包括名字、姓氏、电子邮件、电话号码、密码、出生日期和性别。广播组中的性别，显然使用单选按钮。我正在使用截击来连接数据。如何使用截击传递选中的单选按钮值

这是我目前的java代码：

public class B_Register extends AppCompatActivity implements View.OnClickListener {

public static final String REGISTER_URL = "http://10.0.0.245/register_alex's_app.php";

public static final String FNAME_REGISTER = "first_name";
public static final String LNAME_REGISTER = "last_name";
public static final String EMAIL_REGISTER = "email_register";
public static final String USERNAME_REGISTER = "username_register";
public static final String PHONE_NUMBER_REGISTER = "phone_register";
public static final String PASSWORD_REGISTER = "password_register";
public static final String BDAY_REGISTER = "bday_register";


private EditText fname;
private EditText lname;
private EditText email;
private EditText phone_number;
private EditText new_username;
private EditText new_password;
private EditText bday;

private RadioGroup gender;

private Button register_btn;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.b_register);

    fname = (EditText)findViewById(R.id.first_name_et);
    lname = (EditText)findViewById(R.id.last_name_et);
    email = (EditText)findViewById(R.id.email_et);
    phone_number = (EditText)findViewById(R.id.phone_et);
    new_username = (EditText)findViewById(R.id.username_et);
    new_password = (EditText)findViewById(R.id.password_et);
    bday = (EditText)findViewById(R.id.bday_et);

    gender = (RadioGroup)findViewById(R.id.gender_register);

    register_btn = (Button)findViewById(R.id.register_btn);
    register_btn.setOnClickListener(this);

}

public void onTermsOfUseClick(View view) {
}

@Override
public void onClick(View view) {

    final String firstName = fname.getText().toString().trim();
    final String lastName = lname.getText().toString().trim();
    final String new_email = email.getText().toString().trim();
    final String newPhoneNumber = phone_number.getText().toString().trim();
    final String userName = new_username.getText().toString().trim();
    final String newPassword = new_password.getText().toString().trim();
    final String bDay = bday.getText().toString().trim();

    if(TextUtils.isEmpty(firstName)) {
        fname.setError("Please enter your first name.");
        return;
    }else if(TextUtils.isEmpty(lastName)) {
        lname.setError("Please enter your last name.");
        return;
    }else if(TextUtils.isEmpty(new_email)) {
        email.setError("Please enter your email.");
        return;
    }else if(TextUtils.isEmpty(newPhoneNumber)) {
        phone_number.setError("Please enter your phone number.");
        return;
    }else if(TextUtils.isEmpty(userName)) {
        new_username.setError("Please enter a valid username, 5-25 characters.");
        return;
    }else if (TextUtils.isEmpty(newPassword)) {
        new_password.setError("Please enter valid password, 5-15 characters.");
    }else if (TextUtils.isEmpty(bDay)) {
        bday.setError("Please enter your birth day.");
    }
}
}

要了解所选的

单选按钮

id检查：

 // get selected radio button from radioGroup
 int selectedId = radioGroup.getCheckedRadioButtonId();
 // find the radiobutton by returned id
 radioButton = (RadioButton) findViewById(selectedId);
 String radio_value = radioButton.getText(); //by this you will get the male or female text which will be used in sending to server.

要使用

Volley

发送数据，请添加依赖项：

compile 'com.android.volley:volley:1.0.0'

向服务器发送数据的截取方法：

                try {
                // initialize request to connect the server, via POST method and Server URl
                StringRequest stringRequest = new StringRequest(Request.Method.POST, your_url,
                        new Response.Listener<String>() {
                            // catch JSON response from server
                            @Override
                            public void onResponse(final String response) {
                                // response from server
                            }
                        },

                        // catch error response from server
                        new Response.ErrorListener() {
                            @Override
                            public void onErrorResponse(final VolleyError error) {
                                // trace error message from server 
                            }
                        }){

                    @Override
                    protected Map<String,String> getParams(){
                        Map<String,String> params = new HashMap<String, String>();
                        // map the string value, to send in server
                        params.put("name",string_value_of_name);
                        params.put("sex",string_value_of_sex);
                        .... //like more
                        return params;
                    }
                };

                // execute the request
                RequestQueue requestQueue = Volley.newRequestQueue(your_activity_context.this);
                requestQueue.add(stringRequest);

            }catch (final Exception e){
                //catch exception
            }

试试看{
//通过POST方法和服务器URl初始化连接服务器的请求
StringRequest StringRequest=新建StringRequest（Request.Method.POST，您的url，
新的Response.Listener（）{
//捕获来自服务器的JSON响应
@凌驾
公共void onResponse（最终字符串响应）{
//来自服务器的响应
}
},
//从服务器捕获错误响应
新的Response.ErrorListener（）{
@凌驾
公共错误响应（最终截击错误）{
//来自服务器的跟踪错误消息
}
}){
@凌驾
受保护的映射getParams（）{
Map params=新的HashMap（）；
//映射要发送到服务器的字符串值
参数put（“名称”，字符串值）；
参数put（“sex”，字符串值）；
....//我更喜欢
返回参数；
}
};
//执行请求
RequestQueue RequestQueue=Volley.newRequestQueue（您的\u活动\u上下文。this）；
添加（stringRequest）；
}捕获（最终异常e）{
//捕获异常
}

注：此示例仅用于演示，不包含用户要求的确切答案，必须使用所示流程/逻辑应用您的想法

直接访问单选按钮，而不是radiogroup

RadioButton male = (RadioButton) findViewById(R.id.male);
boolean isMale = male.isChecked();

记得给你的单选按钮贴上标签

<RadioGroup
    android:id="@+id/gender_register"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <RadioButton
        android:id="@+id/male"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/radio_male"
        android:checked="true" />

    <RadioButton
        android:id="@+id/female"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/radio_female" />

</RadioGroup>
