以编程方式生成动态 RadioGroup 并对其进行 setOnCheckedChangeListener

Question

我编写了以下用于显示动态单选组和单选按钮的代码。但是我不明白如何将选中的按钮变成 setOnCheckedChangeListener() 方法。有时多个 RadioButton 会点击同一个 RadioGroup。不知道怎么办？

LinearLayout linearLayout = (LinearLayout) findViewById(R.id.ll);

menuSize = 4;

for(i = 0; i < menuSize; i++)
{
    int menuId = controller.getMenuid(i));
    int subMenuSize = controller.getSubMenu(menuId).size();  // Dynamic value from MVC architechture

    TextView textViewHeading = new TextView(getApplicationContext()); // RadioGroup Heading
    textViewHeading.setText(controller.getMenuName(i));    // Set RadioGroup Heading

    linearLayout.addView(textViewHeading);

    RadioGroup radioGroup = new RadioGroup(getApplicationContext());
    radioGroup.setId(i);

    for(j = 0; j < subMenuSize; j++)
    {
        RadioButton radioButton = new RadioButton(getApplicationContext());

        radioButton.setId(j);

        // Get value from HashMap<Integer, ArrayList<SubMenuClass>>
        // Value is used for RadioButton
        radioButton.setText( controller.getSubMenu(menuId).get(j).getSubMenuName()); 

        radioGroup.addView(radioButton);
    }

    radioGroup.setOnCheckedChangeListener(TryRadioButtons.this);

    linearLayout.addView(radioGroup);
}

我想检查 ButtonSubmit Click 是否每个 RadioGroup 都有一个 RadioButton 必须检查。那么如何在 ButtonSubmit ClickEvent 中获取 RadioButton？

提前致谢

Answer 1

这样做，

RadioGroup group = new RadioGroup(this); 
group.setOrientation(RadioGroup.HORIZONTAL);
RadioButton btn1 = new RadioButton(this);
btn1.setText("BTN1");
group.addView(btn1);
RadioButton btn2 = new RadioButton(this);
group.addView(btn2);
btn2.setText("BTN2");
.... 
RadioButton btnN = new RadioButton(this);
group.addView(btnN);
btnN.setText("BTNN");
yourLayout.addView(group);
