Question

请不要说这是重复的问题，因为我在谷歌搜索并尝试每个答案然后也没有得到结果。在我的Listview行中包含一个TextView和三个单选按钮。

问题
当我点击特定行的另一侧时，Listview setOnItemClickListener工作正常，但问题是当我点击单选按钮然后setOnItemClickListener没有调用我不知道为什么？

我希望当我点击或选择任何redioButton然后调用一个方法时，我知道这可以通过适配器实现，但我希望listview onItemClick()方法中的单选按钮点击事件。

对不起英语不好，提前致谢，帮助将不胜感激

                     RadioButton radioButton_present = (RadioButton)view.findViewById(R.id.radioButton_present);
                     RadioButton radioButton_absent = (RadioButton)view.findViewById(R.id.radioButton_absent);
                     RadioButton radioButton_leave = (RadioButton)view.findViewById(R.id.radioButton_leave);

                    if (!radioButton_present.isChecked() && !radioButton_absent.isChecked()
                    && !radioButton_leave.isChecked())
                    {
                        constant.showSnackBar("Please select at least one attendance option");
                    }

使用View方法的onItemClick()参数查找RadioGroup或RadioButton视图。然后根据要求使用该视图。

@Override
public void onItemClick(AdapterView<?> parent, View view, final int position, long id) {

            RadioGroup group = group = (RadioGroup) view.findViewById(R.id.rg_1);
            final RadioButton radioButton_present = (RadioButton)view.findViewById(R.id.radioButton_present);
            final RadioButton radioButton_absent = (RadioButton)view.findViewById(R.id.radioButton_absent);
            final RadioButton radioButton_leave = (RadioButton)view.findViewById(R.id.radioButton_leave);
            group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(RadioGroup radioGroup, int i) {
                    if (!radioButton_present.isChecked() && !radioButton_absent.isChecked()
                            && !radioButton_leave.isChecked())
                    {
                        Toast.makeText(MainActivity.this,"Please select at least one attendance option",Toast.LENGTH_LONG).show();
                    }
                    else if(radioButton_present.isChecked())
                    {
                        Toast.makeText(MainActivity.this,"Student is present",Toast.LENGTH_LONG).show();
                    }
                    else if (radioButton_absent.isChecked())
                    {
                        Toast.makeText(MainActivity.this,"Student is absent",Toast.LENGTH_LONG).show();
                    }
                    else if (radioButton_leave.isChecked())
                    {
                        Toast.makeText(MainActivity.this,"Student is leave",Toast.LENGTH_LONG).show();
                    }
                }
            });


        }

当ListView行包含RadioButton时，ListView setOnItemClickListener不起作用
