Embedding a webview into another view
I have in my application 2 views:
a. res/layout/main.xml - a standard view with 1 button
b. res/layout/web_view.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<WebView android:id="@+id/webview"
android:layout_height="fill_parent"
android:layout_width="fill_parent" />
</LinearLayout>
When I cl开发者_StackOverflow社区ick the button on the first view(a), it loads the webview(b) and loads an url:
// click on the "Browser" button in view a
public void goToWebView(View view) {
setContentView(R.layout.web_view);
WebView mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.google.com");
}
All that is working fine, the url load well but the browser is instantiated into its own view (a third one, not b itself) and my goal is to use the Webview to show some HTML code into my application, not outside of it, in a separate browser.
Anyboyd any idea?
This is done using API level8/Android 2.2.
Thanks for your help. Paul
Actually I finally understood. Even if you programatically load the url with
mWebView.loadUrl("http://www.google.com");
you also have to mofify the default behaviour (which is opening an url in a new browser instance).
The previous code needs 2 enhancements.
// override default behaviour of the browser
private class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
Then, set for the view which uses Webclient the new behaviour:
public void goToWebView(View view) {
setContentView(R.layout.web_view);
WebView mWebView = (WebView) findViewById(R.id.webview);
// add the following line ----------
mWebView.setWebViewClient(new MyWebViewClient());
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.google.com");
}
