在我的程序中，我正在创建一个用户配置文件片段，其中包括名，姓，性别，出生日期，地址1，地址2和手机号码。即使在单选按钮中进行了选择，我在“性别”字段中也得到了空值。并且我收到了“请填写性别字段”的警报。 我是android编程的新手。帮我解决这个问题。 这是我的代码。

答案 0 :(得分：0)
请更改此
RadioButton rb= (RadioButton)group.findViewById(checkedId);
对此：
将其粘贴到OnCreatedView中，从当前代码中从OnClick中删除
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
RadioButton rb= (RadioButton)view.findViewById(checkedId);
gender=rb.getText().toString();
Log.e("gender","=="+gender );
}
});
如果要在Button上单击，请按照以下步骤
在OnCreatedView中查找findViewById
radioSexGroup=(RadioGroup)findViewById(R.id.radioGroup);
在“按钮单击”中使用此按钮：
int selectedId=radioSexGroup.getCheckedRadioButtonId();
radioSexButton=(RadioButton)findViewById(selectedId);
在片段中：
RadioButton rb= (RadioButton)view.findViewById(checkedId);
