Android webview scrolling does not work… here is a solution to the problem.
Android webview scrolling does not work
I
tried to scroll down to the bottom of the page in WebView, and I was using the WebView example that Google provided in its tutorial. I’m using this line of code trying scrolling but it doesn’t work. mWebView.pageDown(true);
Any suggestions on how to scroll programmatically? Thank you.
public class WebViewExample extends Activity {
private static final String LOG_TAG = "WebViewDemo";
private WebView mWebView;
private Handler mHandler = new Handler();
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = mWebView.getSettings();
webSettings.setSavePassword(false);
webSettings.setSaveFormData(false);
webSettings.setJavaScriptEnabled(true);
webSettings.setSupportZoom(false);
mWebView.setWebChromeClient(new MyWebChromeClient());
mWebView.addJavascriptInterface(new DemoJavaScriptInterface(), "demo");
mWebView. loadUrl(" http://www.google.com/search?q=android+webview+scroll+doesnt+work&hl=en&safe=off&prmd=ivns&ei=0b0cTquNNI6WsgP6l7igBQ&start=10&sa=N#sclient=psy&hl=en&safe=off&source=hp&q=android%20webview%20scrollable&pbx=1&oq=&aq=&aqi=&aql=&gs_sm=&gs_upl=&bav=on.2,or.r_gc.r_pw.&fp=c306e119a7d85f91&biw=1280&bih=738&pf=p&pdl=300 ");
this is where I try to scroll, doesn't work
mWebView.pageDown(true);
}
final class DemoJavaScriptInterface {
DemoJavaScriptInterface() {
}
/**
* This is not called on the UI thread. Post a runnable to invoke loadUrl on the UI thread.
*/
public void clickOnAndroid() {
mHandler.post(new Runnable() {
@Override
public void run() {
mWebView.loadUrl("javascript:wave()");
}
});
}
}
/**
* Provides a hook for calling "alert" from javascript. Useful for debugging your javascript.
*/
final class MyWebChromeClient extends WebChromeClient {
@Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
Log.d(LOG_TAG, message);
result.confirm();
return true;
}
}
Solution
I think mWebView.pageDown(true);
Should be called after the content is loaded.
mWebview.setWebViewClient(new WebViewClient() {
public void onPageFinished (WebView view, String url) {
mWebView.pageDown(true);
}
});
