在这里Android编程的初学者。我正在编写一个应用程序，该应用程序具有用于性别/身高/体重的设置页面，并将此信息计算并传递给另一个活动（主要活动）。
用户返回设置页面时，它将加载用户之前输入的所有值。目前，我的EditText字段加载没有问题，但是性别正在使用旋转器（男性/女性），而设置活动只是在我输入代码时崩溃。
它似乎在integer.parseint（）。
上崩溃预先感谢！

loadPreferences
private void loadSavedPreferences(){
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);

inputWeight.setText(weight);
String height = sharedPreferences.getString("storedHeight", "");
inputHeight.setText(height);
String gender = sharedPreferences.getString("storedGender", "");
Integer genderValue = Integer.parseInt(gender);
chooseGender.setSelection(genderValue);
}
尝试了阿米特的建议，但仍然崩溃。如下记录猫：
