- 햄버거 버튼을 누르면 drawer 오픈
- 리스트 클릭 시 해당 화면으로 전환
1.
app/res/layout폴더에서 first_layout.xml생성 & 텍스트를 "첫 번째 화면"으로 변경
2.
복사&붙여넣기로 같은 폴더에 second_layout.xml생성 & 텍스트를 "두 번째 화면"으로 변경
3.
app/java/com.example~~ 폴더(MainActivity파일이 있는 폴더)에 FirstLayout java파일 생성
* public class FirstLayout extends Fragment
FirstLayout 클래스에 Fragment를 extends.
FirstLayout |
package com.example.han.tutorial4;
import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
/**
* Created by HAN on 2018. 1. 7..
*/
// extends Fragment
public class FirstLayout extends Fragment {
// command + n 누르면 override methods 활용 가능
View v;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
v = inflater.inflate(R.layout.first_layout, container, false);
return v;
}
}
|
같은 방법으로 SecondLayout생성
4.
app/res/menu/activity_main_drawer.xml 파일에서 리스트에 나올 텍스트와 id연결 수정
activity_main_drawer.xml |
<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:showIn="navigation_view">
<group android:checkableBehavior="single">
<item
android:id="@+id/nav_first_layout"
android:icon="@drawable/ic_menu_camera"
android:title="첫 번째 화면" />
<item
android:id="@+id/nav_second_layout"
android:icon="@drawable/ic_menu_gallery"
android:title="두 번째 화면 " />
</group>
<item android:title="Communicate">
<menu>
<item
android:id="@+id/nav_share"
android:icon="@drawable/ic_menu_share"
android:title="Share" />
<item
android:id="@+id/nav_send"
android:icon="@drawable/ic_menu_send"
android:title="Send" />
</menu>
</item>
</menu>
|
5.
R.id.content_main으로 접근하기 위해 app/res/layout/content_main.xml에 아래의 코드 추가
android:id="@+id/content_main"
content_main.xml |
<?xml version="1.0" encoding="utf-8"?> <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.example.han.tutorial4.MainActivity"
tools:showIn="@layout/app_bar_main">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
