The only way to define the layout file in good webView, listening in Java code, webview itself is a browser, Google built-in browser, so you can load the page directly, webview also use the JavaScript scripting language
<?xml version="1.0" encoding="utf-8"?> <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=".MainActivity"> <WebView android:id="@+id/webView" android:layout_width="match_parent" android:layout_height="500dp"></WebView> </RelativeLayout>
The above is the layout file
public class MainActivity extends AppCompatActivity { WebView webView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); webView = findViewById(R.id.webView); webView.getSettings().setJavaScriptEnabled(true); webView.loadUrl("https://www.baidu.com/?tn=62095104_19_oem_dg"); webView.setWebViewClient(new WebViewClient() { @Override public void onPageStarted(WebView view, String url, Bitmap favicon) { super.onPageStarted(view, url, favicon); System.out.println("开始加载"); } @Override public void onPageFinished(WebView view, String url) { super.onPageFinished(view, url); System.out.println("结束加载"); } @Override public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) { return super.shouldOverrideUrlLoading(view, request); } }); webView.setWebChromeClient(new WebChromeClient() { @Override public void onReceivedTitle(WebView view, String title) { super.onReceivedTitle(view, title); System.out.println("显示标题"); } @Override public void onProgressChanged(WebView view, int newProgress) { super.onProgressChanged(view, newProgress); System.out.println("显示加载进度" + newProgress + "%"); } }); } @Override public boolean onKeyDown ( int keyCode, KeyEvent Event) { IF (keyCode == KeyEvent.KEYCODE_BACK && webView.canGoBack ()) { webView.goBack (); // Return to the previous page instead of exiting the browser return to true ; } return Super .onKeyDown (the keyCode, Event); } @Override protected void onDestroy () { IF (! the webView = null ) { webView.loadDataWithBaseURL ( null , "", "text / HTML", "UTF-. 8", null ); webView.clearHistory(); //销毁Webview ((ViewGroup) webView.getParent()).removeView(webView); webView.destroy(); webView = null; } super.onDestroy(); } }
Finally, do not forget to network rights
