환경 설정 활동으로 전환 할 때마다 실행 시간 오류가 발생합니다. 나는 안드로이드 프로그래밍을 배우려고 노력 중이며, 내가 가진 문제를 해결할 수 있었지만, 도움을 찾고있는 시간이 길어서 내가 뭘 잘못하고 있는지 이해할 수 없었다.addPrefencesFromResource 원인 FC : Error inflating class CheckboxPreference
package com.wisp.sudokuapp;
import android.os.Bundle;
import android.preference.PreferenceActivity;
public class Settings extends PreferenceActivity {
@SuppressWarnings("deprecation")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.settings);
}
}
내 Settings.XML의 :
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android" >
<CheckboxPreference
android:key="hints"
android:title="@string/settings_hints_title"
android:summary="@string/settings_hints_summary"
android:defaultValue="true" />
<CheckboxPreference
android:key="music"
android:title="@string/settings_music_title"
android:summary="@string/settings_music_summary"
android:defaultValue="true" />
</PreferenceScreen>
내 매니페스트 :
(...)
<activity android:name="com.wisp.sudokuapp.Settings"
android:label="@string/settings_title">
</activity>
(...)
그리고 로그 캣 :

는 Settings.java의 코드이 방법은 쓸모가 없다는 것을 알고 있지만, 2.3.x에서 사용하고 싶습니다. 안드로이드 개발을 배우기 위해 나는 책을 읽고 책을 읽는다고 생각합니다. addPreferencesFromResource라는 줄을 주석 처리하면 앱이 손상되는 것을 방지 할 수 있지만 UI가로드되지 않습니다.
정말 감사드립니다.
영어로 죄송합니다.
오, 나는 어리 석다. 특히 몇 시간이 지난 후에 문제를 찾으려고 길을 잃었습니다. 고맙습니다. – Adelaiglesia
