[안드로이드] 뒤로가기 버튼 두번 종료

Timer와 같은 클래스를 사용하지 않고 간단하게 구현~ 

   public class MainActivity extends Activity {
    
       private final long	FINSH_INTERVAL_TIME    = 2000;
       private long		backPressedTime        = 0;
    
       @Override 
       protected void onCreate( Bundle savedInstanceState ) {
           super.onCreate( savedInstanceState );
           setContentView( R.layout.activity_main ); 
      } 
   
      @Override 
      public void onBackPressed() {
          long tempTime        = System.currentTimeMillis();
          long intervalTime    = tempTime - backPressedTime;
   
          if ( 0 <= intervalTime && FINSH_INTERVAL_TIME >= intervalTime ) {
              super.onBackPressed(); 
          } 
          else { 
              backPressedTime = tempTime; 
              Toast.makeText(getApplicationContext(),"'뒤로'버튼을한번더누르시면종료됩니다.",Toast.LENGTH_SHORT).show(); 
          } 
      } 
  }
