                }else{
                    fragmentTransaction.attach(mFragment);
                }

            Log.d(TAG,"onTabUnselected() Called.");
            if(mFragment != null){
                fragmentTransaction.detach(mFragment);

            }
        }
        @Override

            Toast.makeText(mActivity, "ReSelected!!!", Toast.LENGTH_SHORT).show();


        }
    }



    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.

        switch (item.getItemId()){
            case R.id.action_settings:
                Toast.makeText(MainActivity.this,"설정이 눌렸습니다.",Toast.LENGTH_SHORT).show();
                break;
        }
        return super.onOptionsItemSelected(item);
    }
}

코드는 이렇게 되어 있습니다. 질문은 viewpager 방식으로 화면을 이동 하면 tabListener 의 onTabSelected() 가 호출됩니다.

그리고 Tab 방식으로 화면을 이동할때는 onTabReselected() 가 호출됩니다. 즉, Tab 방식으로 화면을 이동할때 onTabUnselected()

-> onTabSelected() -> onTabReselected() 가 동시에 이루어집니다. 여기서 해결하고싶은 문제는 Tab방식으로 이동할때 onTabReselected()가 호출이 안되게끔 하고 싶습니다. 부탁드리겠습니다. ㅠ_ㅠ
