그리고 아래는 내가 사용한 코드입니다. 다음은
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.ListPreference;
import android.preference.Preference;
import android.preference.PreferenceActivity;
import android.preference.PreferenceCategory;
import android.preference.PreferenceFragment;
import android.util.Log;
import com.google.android.gms.analytics.GoogleAnalytics;
import org.jraf.android.backport.switchwidget.SwitchPreference;
public class SettingsActivity extends PreferenceActivity {
private static final String TAG = "SettingsActivity";
SharedPreferences mPrefs;
SharedPreferences.Editor editor;
PreferenceCategory prefCategoryGenerals;
ListPreference pitchLevel, recordingType, visualizerType;
SwitchPreference showQuestionTextSwitch, visualizerSwitch;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//addPreferencesFromResource(R.xml.settings);
//getSherlock().getActionBar().setDisplayHomeAsUpEnabled(true);
getFragmentManager().beginTransaction().replace(android.R.id.content, new MyPreferenceFragment()).commit();
//mPrefs = getSharedPreferences(Util.PREFS_SETTINGS, MODE_PRIVATE);
//editor = mPrefs.edit();
}
public static class MyPreferenceFragment extends PreferenceFragment
{
@Override
public void onCreate(final Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.settings);
}
}
@Override
protected void onResume() {
//init();
super.onResume();
}
@Override
protected void onStart() {
//EasyTracker.getInstance().activityStart(this); // Add this method.
GoogleAnalytics.getInstance(this).reportActivityStart(this);
super.onStart();
}
@Override
public void onStop() {
super.onStop();
// The rest of your onStop() code.
//EasyTracker.getInstance().activityStop(this); // Add this method.
GoogleAnalytics.getInstance(this).reportActivityStop(this);
}
Preference.OnPreferenceChangeListener changeListener = new Preference.OnPreferenceChangeListener() {
public boolean onPreferenceChange(Preference preference, Object newValue) {
if (newValue instanceof String) {
editor.putString(preference.getKey(), (String)newValue);
editor.commit();
} else if (newValue instanceof Boolean) {
editor.putBoolean(preference.getKey(), (Boolean)newValue);
editor.commit();
}
Log.e(preference.getKey(),newValue.toString());
updatePreferences();
return true;
}
};
private void init() {
prefCategoryGenerals = (PreferenceCategory)findPreference(getString(R.string.settings_general));
pitchLevel = (ListPreference)findPreference(getString(R.string.pitch_duration));
pitchLevel.setOnPreferenceChangeListener(changeListener);
recordingType = (ListPreference)findPreference(getString(R.string.recording_type));
recordingType.setOnPreferenceChangeListener(changeListener);
visualizerSwitch = (SwitchPreference)findPreference(getString(R.string.visualizer));
visualizerSwitch.setOnPreferenceChangeListener(changeListener);
showQuestionTextSwitch = (SwitchPreference)findPreference(getString(R.string.question_text));
showQuestionTextSwitch.setOnPreferenceChangeListener(changeListener);
visualizerType = (ListPreference)findPreference(getString(R.string.visualizer_type));
visualizerType.setOnPreferenceChangeListener(changeListener);
updatePreferences();
}
private void updatePreferences() {
boolean recordingTypeVideo = mPrefs.getString(Util.PREFS_RECORDING_TYPE, Util.PREFS_RECORDING_A).equals(Util.PREFS_RECORDING_V);
boolean visualizerEnabled = mPrefs.getBoolean(Util.PREFS_SHOW_VISUALIZER, false);
boolean visualizerTypeEnabled = !recordingTypeVideo && visualizerEnabled;
visualizerType.setEnabled(visualizerTypeEnabled);
visualizerSwitch.setEnabled(!recordingTypeVideo);
}
}
그리고는 Settings.xml 파일의 코드입니다.

위의 코드 전체는 Android 4.4.4 에뮬레이터 및 장치에서도 잘 작동합니다.
질문을 편집하고 전체 Java 스택 추적을 게시하는 것이 좋습니다. 일시적으로 타사 환경 설정을 주석으로 처리하고 그 중 하나가 문제의 출처인지 확인하는 것이 좋습니다. – CommonsWare
예 모든 라이브러리를 제거하고 검사했지만 여전히 코드가 작동하지 않습니다. 전체 스택 추적을 업데이트합니다. –
'org.jraf.android.backport.switchwidget.SwitchPreference'와'com.iq.android.preferences.AboutDialogPref'는 유효한 클래스입니까? 패키지 이름을 다시 확인하십시오. – azizbekian
