如何在EditText首选项androidx中使用数字？

implementation 'androidx.appcompat:appcompat:1.4.0'
implementation 'androidx.preference:preference:1.1.1'

<EditTextPreference
    android:key="number_preference"
    android:title="Number Preference"
    android:summary="Enter a number"
    android:dialogTitle="Enter a number"
    android:dialogMessage="Please enter a number"
    android:defaultValue="0"
    android:inputType="number" />

import androidx.preference.EditTextPreference;
import androidx.preference.Preference;
import androidx.preference.PreferenceFragmentCompat;
import androidx.preference.PreferenceManager;

public class MySettingsFragment extends PreferenceFragmentCompat {
    
    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        setPreferencesFromResource(R.xml.preferences, rootKey);
        
        EditTextPreference numberPreference = findPreference("number_preference");
        numberPreference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
            @Override
            public boolean onPreferenceChange(Preference preference, Object newValue) {
                // 处理首选项变化的逻辑
                return true;
            }
        });
    }
}

numberPreference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
    @Override
    public boolean onPreferenceChange(Preference preference, Object newValue) {
        String stringValue = (String) newValue;
        try {
            int numberValue = Integer.parseInt(stringValue);
            // 处理数字值的逻辑
        } catch (NumberFormatException e) {
            // 处理非法输入的逻辑
        }
        return true;
    }
});
