我已经使用下列$ C $下建于放大缩小控制

Hi i have used following code for built in zoom in zoom out control

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

也是我用code像下面

also i have used code like 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);
    }

}

但还是web视图不中内置了放大缩小控制任何机构可以帮助我解决这个问题。

but still webview does not come with built in zoom in zoom out control can any body help me to solve this problem

推荐答案

你有一个视meta标签在网页中显示？如果是的话，如果它包含用户可升级=无则是正常的，在HTML本身禁用变焦。只需编辑标记是这样的：

Do you have a viewport meta tag in web page to display? If yes and if it contains user-scalable="no" then it is normal, the HTML itself disables zoom. Simply edit the tag like this:

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