Zoom in / out in a web browser

Question

Hi, I used the following code for inline zoom control

   mWebView = (WebView) findViewById(R.id.webView1);
    mWebView.getSettings().setBuiltInZoomControls(true);
    mWebView.getSettings().setSupportZoom(true);

I also used the code as shown below

    mWebView.setWebViewClient(new MyWebViewClient());
        mWebView.loadUrl(sabNZBurl);
        mWebView.getSettings().setDomStorageEnabled(true);
        mWebView.getSettings().setJavaScriptEnabled(true);
        mWebView.getSettings().setBuiltInZoomControls(true);
        mWebView.getSettings().setSupportZoom(true);
        backwardBtn = (Button) findViewById(R.id.btnBackWard);
        cancelBtn = (Button) findViewById(R.id.btnCancel);
        refreshBtn = (Button) findViewById(R.id.btnRefresh);
        forwardBtn = (Button) findViewById(R.id.btnForward);

        backwardBtn.setOnClickListener(this);
        cancelBtn.setOnClickListener(this);
        refreshBtn.setOnClickListener(this);
        forwardBtn.setOnClickListener(this);

   final class MyWebViewClient extends WebViewClient {
    @Override
    // Show in WebView instead of Browser
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }

    @Override
    public void onLoadResource(WebView view, String url) {
        super.onLoadResource(view, url);

    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        PD.dismiss();
        view.getSettings().setBuiltInZoomControls(true);
        view.getSettings().setSupportZoom(true);
    }

}

but still web browsing doesn't come with built-in zoom in zoom out controls. Any body can help me solve this problem.

Answer 1

Do you have a viewport meta tag on a webpage to display? If yes, and if it contains user-scalable="no", then this is normal, HTML itself disables scaling. Just edit the tag as follows:

<meta name="viewport" content="initial-scale=1.0, user-scalable=yes, width=device-width" />

Answer 2

Try it, I got an answer

WebSettings webSetting = mWebView.getSettings();
            webSetting.setBuiltInZoomControls(true);

Answer 3

Perhaps this is what you are looking for.

settings.setBuiltInZoomControls(true);
settings.setSupportZoom(true);
settings.setUseWideViewPort(true);
settings.setJavaScriptEnabled(true);
settings.setJavaScriptCanOpenWindowsAutomatically(true);

Answer 4

try the following: -

webview.getSettings().setUseWideViewPort(true);
