Activity Default는 스택이 쌓이지 않음. 그러므로 Layout에서도 history true 기본이 적용되지 않음.
다음 코드를 넣어야 함@Override public boolean onKeyDown(int keyCode, KeyEvent event) { WebView view = (WebView) findViewById(R.id.crawl_wvLayout); if ((keyCode == KeyEvent.KEYCODE_BACK) && view.canGoBack()) { view.goBack(); return true; } return super.onKeyDown(keyCode, event); }activity_crawl_main의 디폴트
activity_main과 manifest와의 상관 관계
균형 깨지면 error<RelativeLayout 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" tools:context=".CrawlActivity"> <FrameLayout android:id="@+id/fl_activity_main" android:layout_width="match_parent" android:layout_height="match_parent"> <WebView android:id="@+id/crawl_wvLayout" android:layout_width="fill_parent" android:layout_height="fill_parent" tools:ignore="MissingConstraints" /> </FrameLayout> </RelativeLayout>이상적인 Jsoup

web.loadUrl로 선언 된 WebView와 일치를 안 시켰기 때문.
아래 코드의 경우
public void onBackPressed() { if (webView.canGoBack()) webView.goBack(); else finish(); }webView로는 작동을 안 하지만(다른 개체로 인식되므로)
아래와 같이 web으로 인식되는 것은 web.loadUrl으로 선언된 url과 일치하기 때문
상기의 다양한 코드를 사용할 수 있음public void onBackPressed() { if (web.canGoBack()) web.goBack(); else finish(); }간단하게(기능하지 않음)
private WebView mWebView; public void onBackPressed() { if(mWebView.canGoBack()){ mWebView.goBack(); }else{ super.onBackPressed(); } }일반적인
import * as React from 'react'; import { WebView } from 'react-native-webview'; export default class App extends React.Component { render() { return <WebView source={{ uri: 'https://mimoonchurch.net' }} style={{ marginTop: 20 }} />; } }비 사용 코드(주로 Content View Code)
