SharedPreferences 사용법

간단한 읽고, 쓰기

 

//load private SharedPreferences appData; protected void onCreate(Bundle savedInstanceState) { appData = getSharedPreferences("map", MODE_PRIVATE); } //읽기 public void btnReadClick(View view) { String value = appData.getString("walkthrough", "");//""인 기본 값 if (value.equals("")) { intent = new Intent(getApplicationContext(), OnBoardingActivity.class); startActivity(intent); } } //쓰기 public void btnWriteClick(View view) { SharedPreferences.Editor editor = appData.edit(); editor.putString("walkthrough", "test"); editor.apply(); Toast.makeText(this, "설정값 초기화", Toast.LENGTH_SHORT).show(); }

 

 

getString이외에  getInt, getBoolean도 있음.
