title: zoom in/out (+/-) in webview android
body: <p>In my application I have one Webview and two buttons next and previous. First time load content from database after that I zoom my Webview and change the page using next button then display content but the zooming is stated. </p>
  
  <p>So my question is that how I change a Webview in initial scale?</p>
  
  <p>I used this:</p>
  
  <pre><code>web1.getSettings().setBuiltInZoomControls(true); 
  </code></pre>
  
  <p>and after click on next page used this:</p>
  
  <pre><code>web1.getSettings().setDefaultZoom(ZoomDensity.FAR);
  web1.setInitialScale(100);
  </code></pre>
  
  <p>but no any effects. </p>
  
  <p>Please help me. </p>
