如何在android中增加WebView的字体大小

如何在android中增加WebView的字体大小？我已经给出了下面的代码，但它不起作用。有人能告诉我怎么做吗

blogWebView.getSettings().setDefaultFontSize(14);

您可以在webview中使用缩放控制。请参阅下面的代码

  FrameLayout mContentView = (FrameLayout) getWindow().

    getDecorView().findViewById(android.R.id.content);

    final View zoom = this.mWebView.getZoomControls();

    mContentView.addView(zoom, ZOOM_PARAMS);

    zoom.setVisibility(View.GONE);


  private static final FrameLayout.LayoutParams ZOOM_PARAMS =

    new FrameLayout.LayoutParams(

    ViewGroup.LayoutParams.FILL_PARENT,

    ViewGroup.LayoutParams.WRAP_CONTENT,

    Gravity.BOTTOM);


 webview.getSettings().setDefaultZoom(WebSettings.ZoomDensity.FAR)
