        tv_login.setOnClickListener(this);
    }
    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.tv_login:
                goToLogin();
                break;
            case R.id.btn_register:
                String name = et_name.getText().toString();
                String email = et_email.getText().toString();

我的xml代码：

 <RadioGroup
        android:id="@+id/radioGrp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:layout_marginBottom="8dp">
        <RadioButton
            android:id="@+id/radioM"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="left"
            android:checked="false"
            android:layout_weight="1"
            android:textSize="14dp"
            android:text="Male"
            />
        <RadioButton

PHP MySql 的 java 代码中的字符串声明

private String gender;
 public String getGender() {
        return gender;
    }
 public void setGender(String gender) {
        this.gender = gender;// in my database text( eg: M/F) store in gender field
    }

只需获取 Radio Group 和 radioGroup.getCheckedRadioButtonId() 的引用，如下面的代码，您就可以获取已选中单选按钮的值

// get selected radio button from radioGroup
        int selectedId = radioGroup.getCheckedRadioButtonId();

        // find the radiobutton by returned id
        radioButton = (RadioButton) findViewById(selectedId);

    if(radioButton!=null)
    {
         Toast.makeText(MyAndroidAppActivity.this,
                    radioButton.getText(), Toast.LENGTH_SHORT).show();
    }
