This article introduces you how to use WebView components, the content is very detailed, interested friends can refer to, hope to be helpful to you.

A high-performance webkit kernel browser is built into the Android phone, which is encapsulated into a WebView component in SDK, which can be used to browse web content. So, how do you use it?

Load a component using the WebView control for the first time

1) mainfest.xml adds internet permission

Manifest >

2) add webView components to layout

LinearLayout >

3) add activity

Package com.example.webview1; import android.app.Activity; import android.os.Bundle; import android.view.KeyEvent; import android.view.Menu; import android.webkit.WebView; import android.webkit.WebViewClient; public class WebViewActivity extends Activity {private WebView webView; @ Override public void onCreate (Bundle savedInstanceState) {super.onCreate (savedInstanceState); setContentView (R.layout.activity_web_view); webView = (WebView) findViewById (R.id.webview) / / set javasctipt available webView.getSettings () .setJavaScriptEnabled (true); / / load url, but it will not be displayed, pay attention! WebView.loadUrl ("http://www.baidu.com"); / / specify display control (class) webView.setWebViewClient (new myWebViewClient ());} @ Override public boolean onCreateOptionsMenu (Menu menu) {getMenuInflater () .inflate (R.menu.activity_web_view, menu); return true } / / to make the fallback key work @ Override public boolean onKeyDown (int keyCode, KeyEvent event) {/ / TODO Auto-generated method stub if (keyCode==event.KEYCODE_BACK&&webView.canGoBack ()) {webView.goBack (); return true;} return super.onKeyDown (keyCode, event) } / * * webView View client * @ author Administrator * * / class myWebViewClient extends WebViewClient {@ Override public boolean shouldOverrideUrlLoading (WebView view, String url) {/ / TODO Auto-generated method stub / / return super.shouldOverrideUrlLoading (view, url); webView.loadUrl (url); return true }
