Webview height not changing after resize font size

问题:

In my application I use a ScrollView. This ScrollView contain many Webview. I change the webview font size:

webView.getSettings().setTextSize(WebSettings.TextSize.LARGER);

after I change again the font size:

webView.getSettings().setTextSize(WebSettings.TextSize.SMALLER);

The font size is changing, but the webview layout height is not changing. The text is smaller and there are a big space. There are any method to this problem?

回答1:

you might have to reload your webview with ie:

webview.loadUrl( "javascript:window.location.reload( true )" );

I had the same problem and fixed it using code:

private void reloadWebView() {
    postDelayed(new Runnable() {
        @Override
        public void run() {
            clearView();
            requestLayout();
        }
    }, 10);
}

Call it method when You have finished zooming. It will refresh web view and recalculate it size.

You can use this:

myWebView.loadUrl("about:blank");

private void reloadWebView() {
    // TODO Auto-generated method stub
    postDelayed(new Runnable() {
        @Override
        public void run() {
            clearView();
            reload();               
            myWebView.getSettings().setJavaScriptEnabled(true);
            requestLayout();
        }
    }, 10);
}
