Question

我正在创建新的应用程序，这个应用程序怀孕，我想选择一个日期，我有最后的日期和截止日期，但我想选择使用单选按钮，然后选择。请帮我谢谢。

这是我的代码：

radioGroup_date = (RadioGroup) findViewById(R.id.radio_Date);
radioGroup_date.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, @IdRes int checkedId) {

                int selectedId = radioGroup_date.getCheckedRadioButtonId();//new
                radioButton_date = (RadioButton) findViewById(selectedId);//new
                String text = radioButton_date.getText().toString();//new
                Toast.makeText(getApplicationContext(), text, Toast.LENGTH_SHORT).show();//new

            }
        });

        final Calendar c = Calendar.getInstance();
        year = c.get(Calendar.YEAR);
        month = c.get(Calendar.MONTH);
        day = c.get(Calendar.DAY_OF_MONTH);

        editText_calander.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //DateDialog();
                showDialog(DATE_PICKER_ID);
            }
        });

        button_Submit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dob = editText_calander.getText().toString();

                SharedPreferences.Editor editor = sharedpreferences.edit();
                editor.putString("dob", dob);
                editor.commit();

                Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
                Bundle b = new Bundle();

//                int selectedId = radioGroup_date.getCheckedRadioButtonId();
//                radioButton_date = (RadioButton) findViewById(selectedId);
                b.putString("baby_name", editText_baby_name.getText().toString());
                b.putString("mother_name", editText_mother_name.getText().toString());
                intent.putExtras(b);

                startActivity(intent);
            }
        });
