我已从 firestore 数据库中检索了性别值，该值是一个字符串。
现在将此值设置为性别的 Spinner，以便用户可以自行检查和更新该值。
检索到的值应该显示，但我无法转换字符串值并将其设置为 android 中的微调器。
我尝试搜索类似的示例，但还没有成功。

关注的是 getUserProfileDetails() 方法中的这些行
uGender.setText(gender);
uSpinnerC.setText(spinnerC);
最佳答案
您可以检查您的 Spiner 文本是否为男性，然后 setSelection 1 或 0，如下所示
String spinnerC = (String) document.getString("spinnerC");
if (spinnerC.equals("Male")){
uSpinnerC.setSelection(0);
}else{
uSpinnerC.setSelection(1); //female case
}
