[Android] Fragment 적용 방법

1. fragment를 넣고 싶은 xml에 다음 코드 추가

activity_search.xml

<FrameLayout android:id="@+id/fragment_container" android:layout_width="match_parent" android:layout_height="wrap_content" app:layout_constraintTop_toBottomOf="@id/btn_back"> </FrameLayout>

2. fragment안에 들어가는 xml 파일 생성

=> fragment_search.xml

3. SearchFragment.java 생성

import android.content.Context; import android.os.Bundle; import android.support.annotation.Nullable; import android.support.v4.app.Fragment; //이걸로 import import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Button; public class SearchResultFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_search, container, false); return rootView; } }

4. SearchActivity.java 다음 코드 추가

SearchResultFragment searchResultFragment = new SearchResultFragment(); getSupportFragmentManager().beginTransaction().add(R.id.fragment_container, searchResultFragment).commit();

빨간 글씨 파란 글씨만 주의하면 ok!!
