放大/缩小webview android [英] Zoom in/out in webview android

问题描述

我使用以下代码进行内置放大缩小控制

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);

我也使用过如下代码

    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);
    }

}

但是 webview 仍然没有内置放大缩小控件可以帮助我解决这个问题

推荐答案

试试这个，我有答案

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