使用webview将网页打包成apk

public class MainActivity extends Activity {
    private WebView webview;  
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        webview = (WebView) findViewById(R.id.webview);  
        //设置WebView属性，能够执行Javascript脚本  
        WebSettings webSettings= webview.getSettings(); // webView: 类WebView的实例
        webSettings.setJavaScriptEnabled(true);
        webSettings.setSupportZoom(true);   

        //设置默认缩放方式尺寸是far   

        webSettings.setDefaultZoom(WebSettings.ZoomDensity.FAR);  

        //设置出现缩放工具   

        webSettings.setBuiltInZoomControls(true);
        webSettings .setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);  
        //加载需要显示的网页  
        webview.loadUrl("http://www.csdn.net/");  
        //设置Web视图  
        webview.setWebViewClient(new HelloWebViewClient ());  
    }

    @Override 
    //设置回退  
    //覆盖Activity类的onKeyDown(int keyCoder,KeyEvent event)方法  
    public boolean onKeyDown(int keyCode, KeyEvent event) {  
        if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) {  
            webview.goBack(); //goBack()表示返回WebView的上一页面  
            return true;  
        }  
        return false;  
    }  
      
    //Web视图  
    private class HelloWebViewClient extends WebViewClient {  
        @Override 
        public boolean shouldOverrideUrlLoading(WebView view, String url) {  
            view.loadUrl(url);  
            return true;  
        }  
    } 

}
