在以编程方式创建RadioButton时，会出现错误：错误的状态类，期望View State但是收到了类

Question

我是android开发的新手。我正在以编程方式创建RadioButton但是我发现了这个错误：

  

错误的州级，期待View State但是收到了类android.widget.CompoundButton $ SavedState。当两个不同类型的视图在同一层次结构中具有相同的id时，通常会发生这种情况。该视图的id为id / 0x4。确保其他视图不使用相同的ID。

我的代码是:: DynamicFormCreation.java

function translateAlong(path) {
    return function(d, i, a) {
        return function(t) {
            var p = path.getPointAtLength(t*data.length*100);
            // Update the text inside the text element:
            text.text("X is " + p.x + "Y is " + p.y);
            return "translate(" + p.x + "," + p.y + ")";
         };
    };
}

调用该函数::

 public RadioGroup createRadioButton(String[] option, Context context, int parentId) {

    final RadioButton[] rb = new RadioButton[5];
    RadioGroup rg = new RadioGroup(context);
    rg.setPadding(5, 5, 0, 5);
    DisplayMetrics metrics = new DisplayMetrics();
    WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    wm.getDefaultDisplay().getMetrics(metrics);
    final float width = metrics.widthPixels;
    rg.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
    rg.setMinimumHeight(UtilityClass.intToDpi(65, context));
    rg.setOrientation(RadioGroup.HORIZONTAL);

    for (int i = 0; i < 5; i++) {
        if (option[i] != null && option[i].trim().length() > 0) {
            rb[i] = new RadioButton(context);
            rg.addView(rb[i]);
            rb[i].setTextColor(Color.BLACK);
            rb[i].setText(option[i]);
        }
    }
    return rg;
}

在activity ::

中调用此类

RadioGroup relgroup = createRadioButton(option, context, parentId);
rel.addView(relgroup);
parentId++;
