我正在尝试以编程方式生成两个RadioGroup。我成功地生成了第一个，但我需要生成第一个无线电组的第二个onCheckedChangeListener。这是我的活动代码。

答案 0 :(得分：1)
你不只是需要在onCheckChangedListener中重复相同的进程吗？
rg.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
//Create another radio group here
//then add it to the view
RadioGroup rg2 = new RadioGroup(this); //create the RadioGroup
rg2.setOrientation(RadioGroup.HORIZONTAL);//or RadioGroup.VERTICAL
rg2.setPadding(dpAsPixels, dpAsPixels, dpAsPixels, dpAsPixels);
final Drawable drawableTop = getResources().getDrawable(R.drawable.document_icon);
for (int i = 0; i < itemTypeArrayList.size(); i++) {
if (itemTypeArrayList.get(i).getActive() == 1) {
rb = new RadioButton(this);
rg2.addView(rb); //the RadioButtons are added to the radioGroup instead of the layout
rb.setText(itemTypeArrayList.get(i).getCode());
rb.setId(itemTypeArrayList.get(i).getId());
}
}
itemDetailsLinearLayout.addView(rg);
}
});
您可能需要在类的顶部声明rg2 public，以便onCheckChangedListener可以访问它
