如何在android

Question

大家好，                我们希望动态地添加textog旁边的textview。基于服务响应，我们需要在不使用xml的情况下将标签附加到radiogroup。 在某些情况下，基于最大长度无线电

这里是代码

  final RadioGroup rg = new RadioGroup(this); //create the RadioGroup
            rg.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
            rg.setOrientation(RadioGroup.VERTICAL);//or RadioGroup.VERTICAL
            rg.setGravity(Gravity.CENTER);
            final RadioButton[] rb = new RadioButton[items_list.size()];
            final CheckBox[] cb = new CheckBox[items_list.size()];

for (int i = 0; i < items_list.size(); i++) {

                LinearLayout ll_orientaion = new LinearLayout(this);
                ll_orientaion.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT, 2.0f));
                ll_orientaion.setOrientation(LinearLayout.HORIZONTAL);
                ll_orientaion.setBackgroundColor(getResources().getColor(R.color.white));
                ll_orientaion.setWeightSum(2);
                ll_orientaion.setGravity(Gravity.CENTER);


                if (max == 1) {

                    rb[i] = new RadioButton(this);
                    rb[i].setText(pd.getName());
                    rb[i].setGravity(Gravity.CENTER);
                    ll_orientaion.addView(rb[i]);

                    if (pd.getSelected_status().equals("true")) {
                        rb[i].setChecked(true);

                    }

                    hashMap_rdlist.put(rb[i].getText().toString(), rdd);

                    rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
                        @Override
                        public void onCheckedChanged(RadioGroup group, int checkedId) {

                            ProductOptions rd_getlist = new ProductOptions();

                            int checkedRadioButtonId = rg.getCheckedRadioButtonId();
                            RadioButton radioButton = (RadioButton) findViewById(checkedRadioButtonId);
                            //  Toast.makeText(ProductOptionsActivity.this, radioButton.getText(), Toast.LENGTH_SHORT).show();

                            String rd_name = (String) radioButton.getText();

                    });
                } else {

                    cb[i] = new CheckBox(this);
                    cb[i].setButtonTintList(ColorStateList.valueOf(getColor(R.color.colorPrimary)));
                    cb[i].setText(pd.getName());
                    cb[i].setGravity(Gravity.CENTER);
                    ll_orientaion.addView(cb[i]);


                    }

                    final int finalI = i;

                    cb[i].setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                        @Override
                        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                            ProductOptions rd_getlist = new ProductOptions();
                            String check_name = (String) cb[finalI].getText();

                            if (isChecked) {

                                check_count++;


                            } else {
                                check_count--;

                            }
                        }
                    });
                }
                // Log.d("checklist",""+productoptions_skuId);

                TextView tv = new TextView(this);
                LinearLayout.LayoutParams tv1 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, 1.0f);
                tv.setLayoutParams(tv1);
                tv1.weight = 2;
                tv1.gravity = Gravity.CENTER;
                tv.setText(pd.getSalePrice());
                tv.setTextSize(14);
                tv.setGravity(Gravity.END);
                if (pd.getSalePrice().equals("0.0")) {
                    tv.setVisibility(View.INVISIBLE);
                }
                ll_orientaion.addView(tv);
                rg.addView(ll_orientaion);
            }

当我们将LinearLayout添加到radiGroup View时，主要问题是完美但RadioButton操作无效，即

rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {}

请指导我们 谢谢！

使用CheckedTextView为列表视图创建自定义适配器。
