You can use this code to implement a singleton class for configuration
using writable SharedPreferences.
public final class Config {
private static Config INSTANCE = new Config();
private ConfigProperties configProperties;
private Config(){}
public static Config getInstance() {
return INSTANCE;
}
public void init(Context context) {
configProperties = new ConfigProperties(context);
}
}
public class ConfigProperties {
private SharedPreferences preferences;
private SharedPreferences.Editor editor;
public ConfigProperties(Context parent) {
preferences = PreferenceManager
.getDefaultSharedPreferences(parent.getApplicationContext());
editor = preferences.edit();
}
public String getStringProperty(String key) {
return preferences.getString(key, null);
}
public Integer getIntegerProperty(String key) {
return preferences.getInt(key, 0);
}
public Boolean getBooleanProperty(String key) {
return preferences.getBoolean(key, false);
}
public void setStringProperty(String key, String value) {
editor.putString(key, value);
editor.commit();
}
public void setIntegerProperty(String key, int value) {
editor.putInt(key, value);
editor.commit();
}
public void setBooleanProperty(String key, boolean value) {
editor.putBoolean(key, value);
editor.commit();
}
}
