如何查找动态创建的无线电组的ID，每个单选按钮有4个单选按钮

Answer 1

您可以按-Dtitanium.bypassAuthentication=true 为每个视图设置ID，然后按其进行搜索。但是请记住放入没有相同ID的布局视图。

Answer 2

将RadioButton数组声明为全局

例如

RadioButton[] rb = new RadioButton[4]; // declare as globle

更改

 public void onCheckedChanged(RadioGroup group, int checkedId) {
                                            switch (checkedId) {
                                                case R.id.option_1:
                                                    Toast.makeText(getActivity(), "Option 1", Toast.LENGTH_LONG).show();
                                                case R.id.option_2:
                                                    Toast.makeText(getActivity(), "Option 2", Toast.LENGTH_LONG).show();
                                                case R.id.option_3:
                                                    Toast.makeText(getActivity(), "Option 2", Toast.LENGTH_LONG).show();
                                                case R.id.option_4:
                                                    Toast.makeText(getActivity(), "Option 4", Toast.LENGTH_LONG).show();

                                            }

与

@Override
                        public void onCheckedChanged(RadioGroup group, int checkedId)
                        {
                            if(group.getCheckedRadioButtonId() == rb[0].getId())
                            {

                            }
                            else if(group.getCheckedRadioButtonId() == rb[1].getId())
                            {

                            }

                        }
