آموزش استفاده از کلاس SharedPreferences

کد کلاس:

public class SaveID {
private Context m_Context;
public int m_state;
public static final String STATE_id = "id";
public static final String MyPREFERENCES = "Save_ID";
public SharedPreferences m_SharedPreferences;
 public SaveID(Context context) {
	// TODO Auto-generated constructor stub
	 this.m_Context=context;
	 m_SharedPreferences=m_Context.getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
}

public SaveID(Context context, SharedPreferences sharedPreferences) {
	this.m_Context = context;
	this.m_SharedPreferences = sharedPreferences;
}

public void setSharedPreferances(SharedPreferences sharedPreferences){
	this.m_SharedPreferences = sharedPreferences;
}

public void saveState(String m_state){

	Editor editor = this.m_SharedPreferences.edit();
	editor.putString(STATE_id, m_state);
	editor.commit();
}
public String getState(){
	return this.m_SharedPreferences.getString(STATE_id, "");
}
