* 웹뷰를 이용하여 내 앱으로 웹화면을 띄우려고 합니다.
구글링으로 여러가지를 찾아보다가 제가 사용할 웹사이트에 맞게 제작했습니다.
혹시 같은 방식이라면 참고하시기 바랍니다~!!
1. 먼저 매니페스트 파일을 수정합니다. (AndroidManifest.xml)
* 인터넷을 사용하기 위한 설정입니다.
<uses-permission android:name="android.permission.INTERNET" />
* 어플의 아이콘을 변경해보았습니다.
android:icon="원하는 이미지"
* 예시를 보여드리겠습니다.
android:icon="@drawable/icon"
* 사진은 여기에 저장하고 불러옵니다.
* 원하는 어플의 이름을 등록합니다.
android:label="원하는이름"
* 전체 소스입니다.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.changmin.sellee">
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="@drawable/icon"
android:label="원하는 어플이름"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.AppCompat.NoActionBar">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
2. xml소스입니다. (activity_main.xml)
* webview를 webview라는 id로 등록하고 match_parent로 화면전체를 채워줍니다
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:foregroundGravity="center"
android:orientation="vertical"
tools:context="com.example.changmin.sellee.MainActivity">
<WebView
android:id="@+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:foregroundGravity="center" />
</android.support.constraint.ConstraintLayout>
3. java소스입니다. (MainActivity.java)
* 웹뷰를 선언합니다.
public class MainActivity extends AppCompatActivity {
WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.webview);
}
* WebSettings를 사용해서 webview설정을 추가해줍니다.
public class MainActivity extends AppCompatActivity {
WebView webView;
WebSettings webSettings;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.webview);
webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true); // javascript를 실행할 수 있도록 설정
webSettings.setSupportMultipleWindows(true); // 여러개의 윈도우를 사용할 수 있도록 설정
webSettings.setJavaScriptCanOpenWindowsAutomatically(true); // javascript가 window.open()을 사용할 수 있도록 설정
}
* setWebChromeClient와 setWebVeiwClinet함수를 추가해줍니다. 그리고 원하는 url로 연결해줍니다.
public class MainActivity extends AppCompatActivity {
WebView webView;
WebSettings webSettings;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);
webView = (WebView) findViewById(R.id.webview);
webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true); // javascript를 실행할 수 있도록 설정
webSettings.setSupportMultipleWindows(true); // 여러개의 윈도우를 사용할 수 있도록 설정
webSettings.setJavaScriptCanOpenWindowsAutomatically(true); // javascript가 window.open()을 사용할 수 있도록 설정
webView.setWebChromeClient(new MyWebChromeClient());
webView.setWebViewClient(new MyWebViewClient());
webView.loadUrl("첫시작 url (접속하고싶은 url을 입력합니다^^)");}
★ 여기까지가 웹뷰의 기본입니다. 나머지는 풀소스를 올리겠습니다.

MyWebViewClient 클래스의 shouldOverrideUrlLoading
부분은 밑의사이트를 참고했습니다~
출처 :
하나하나 세세한 설명은 못드렸습니다ㅠㅠ
중간에 한번 날려먹어서 그냥 풀소스로 공개합니다~!!
제가 3주정도 삽질하면서 만든 소스입니다. 이렇게 간단한걸 3주씩이나...털썩...
여러가지 방식이 있지만 저는 url을 받아와서 해당url에맞게 구동되도록했습니다.
다른분들은 어떻게 하셨는지 궁금하기도 합니다ㅎㅎㅎ
url을 변경하시고 실행하면 잘될거라고 믿습니다. 궁금한점은 댓글달아주세요^^
