                    }
                }

            }else{
                Log.d(TAG, "No product option ");
                rlProductOptionQuantityTxt.setVisibility(View.VISIBLE);
            }

            btnAddToCart = new Button(getActivity());
            btnAddToCart.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT));
            btnAddToCart.setBackgroundColor(getResources().getColor(R.color.color_btn_login));
            btnAddToCart.setText(getActivity().getResources().getString(R.string.add_to_cart));
            btnAddToCart.setTypeface(Typeface.SERIF);
            btnAddToCart.setTextColor(Color.WHITE);
            llProductOptionsSheet.addView(btnAddToCart);
            btnAddToCart.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    tvOptionTitleText.setError("please fill all the text");
                }
            });

        }else{
            rlProductOption.setVisibility(View.GONE);
            Toast.makeText(getActivity(),response.getString("message"),Toast.LENGTH_SHORT).show();
        }
    } catch (JSONException e) {
        e.printStackTrace();
        Toast.makeText(getActivity(),"Sorry try Later!!!",Toast.LENGTH_SHORT).show();
        rlProductOption.setVisibility(View.GONE);
    }
}

這是我的代碼，我根據json數據添加單選按鈕和復選框。所以當我點擊按鈕“btnAddToCart”然后我想知道所有選中的復選框和單選按鈕。我必須存儲所有選定的數據在我的會議中。

Answer 1

聲明一個全局變量，如：

int rlProductOptionQuantityTxt = 0; //默認情況下

使用Switch case，

@Override public void onClick（查看視圖）{switch（view.getId（））

{

案例R.id.yourRadioButton：

           rlProductOptionQuantityTxt =1;

}

}

然后你可以直接使用全局變量的值。

SetGet.setProductOptionQuantityTxt（rlProductOptionQuantityTxt）;

Answer 2

int radioButtonID = radioButtonGroup.getCheckedRadioButtonId();
View radioButton = radioButtonGroup.findViewById(radioButtonID);
int idx = radioButtonGroup.indexOfChild(radioButton);
