编程生成动态RadioGroup并在其上生成setOnCheckedChangeListener

Question

我做了下面的代码显示动态无线电组和无线电按钮。但我不明白如何将“签入”按钮转到setOnCheckedChangeListener()方法中。有一段时间，多个RadioButton将单击同一个RadioGroup。我不知道怎么回事？

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);
}

我想检查一下ButtonSubmit，点击每个RadioGroup都有一个必须检查的RadioButton。那么我怎样才能得到RadioButton in ButtonSubmit ClickEvent呢？

也许它会帮助你动态地获得无线电按钮。

Answer 2

往这边走，

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);
