===

I am trying to scale the webview  to the size of the screen , but I have failed at it .. I have tried lots of combinations but none of them worked for me .What am I missing in that code ? Any help is greatly appreciated. 

    package com.example.images;

    import android.app.Activity; 
    import android.os.Bundle; 
    import android.webkit.WebView; 
 
    public class MainActivity extends Activity { 
 
    private WebView webView; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
       super.onCreate(savedInstanceState); 
       setContentView(R.layout.main); 
      webView  = (WebView) findViewById(R.id.webview_compontent); 
  
      
      String r="<meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0,target-densityDpi=device-dpi\">"; 
 
            String s="<html><head>"+"<style>body{margin:0; }</style>" +r+"</head>" +"<body>"+
    		   "<IMG src="+ "\"http://46.20.150.55/member/Resimler/kampanya/195/314/blackmakas1.jpg\">" +
    		   "<DIV style=\"Z-INDEX: 1; POSITION: absolute; TEXT-ALIGN: center; BACKGROUND-COLOR: white;" +
    		   "WIDTH: 80px; TOP: 137px; LEFT: 121px\">564524</DIV>"+"</body><html>"; 
    		   
       webView.setBackgroundColor(0); 
       webView.setBackgroundResource(R.drawable.android); 
       webView.loadData(s, "text/html","UTF-8");  

  
       
      //doesn't work
      /*webView.getSettings().setLoadWithOverviewMode(true); 
       webView.getSettings().setUseWideViewPort(true); 

       try { 
           // load the url 
           webView.loadData(s, "text/html","UTF-8");
       } catch (Exception e) { 
           e.printStackTrace(); 
       } */
      
       //doesn't work
       
     /* webView.setInitialScale(1); 
      webView.getSettings().setLoadWithOverviewMode(true); 
      webView.getSettings().setUseWideViewPort(true); 
      webView.getSettings().setJavaScriptEnabled(true); 
      */
       
      //doesn't work
  
      /* String p="<html><head>"+"<style>body{margin:0; }</style>" +r+"</head>" +"<body>"+
    		   "<IMG src="+ "\"http://46.20.150.55/member/Resimler/kampanya/195/314/blackmakas1.jpg\">" +
    		   "<DIV style=\"Z-INDEX: 1; POSITION: absolute; TEXT-ALIGN: center; BACKGROUND-COLOR: white;" +
    		   "WIDTH: 80px; TOP: 137px; LEFT: 121px\">564524</DIV>"+"</body><html>"; 
    		   
       webView.loadData(p, "text/html","UTF-8");
     
       webView.getSettings().setJavaScriptEnabled(true); 
       webView.getSettings().setLoadWithOverviewMode(true); 
       webView.getSettings().setUseWideViewPort(true); 
       webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY); 
       webView.setScrollbarFadingEnabled(false);   */   
   
      } }
