The Hello WebView demo and documentation on the Android developer site (http://developer.android.com/guide/tutorials/views/hello- webview.html) is broken. Here are the required fixes to get it to work properly:
main.xml: change wrap_parent to fill_parent, like so: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <WebView android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout> ========================================== in HelloWebView.java, you need to add a few imports that aren't mentioned in the docs: import android.view.KeyEvent; import android.webkit.WebView; import android.webkit.WebViewClient; In the OnCreate method, change the following code: - from this: webview.setWebViewClient(new WebViewClientDemo()); - to this: webview.setWebViewClient(new HelloWebViewClient()); If you prefer, here's the complete HelloWebView.java code: ============================ package org.example.hellowebview; import android.app.Activity; import android.os.Bundle; import android.view.KeyEvent; import android.webkit.WebView; import android.webkit.WebViewClient; public class HelloWebView extends Activity { /** Called when the activity is first created. */ WebView webview; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); webview = (WebView) findViewById(R.id.webview); webview.setWebViewClient(new HelloWebViewClient()); webview.getSettings().setJavaScriptEnabled(true); webview.loadUrl("http://www.google.com";); } private class HelloWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } } public boolean onKeyDown(int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) { webview.goBack(); return true; } return super.onKeyDown(keyCode, event); } } ================================= Hope this helps! [thanks to Mark Murphy's webkit source code from http://commonsware.com/Android/ for some examples that helped me pin down the errors in Google's docs]. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
