Android -- Webview自适应屏幕

第一种                                                                                         

WebSetting settings = webView.getSettings();
settings.setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);

把所有内容放在webview等宽的一列中。（可能会出现页面中链接失效）

第二种                                                                                         

settings.setUseWideViewPort(true);
settings.setLoadWithOverviewMode(true);

第三种                                                                                         

DisplayMetrics metrics = new DisplayMetrics();
     getWindowManager().getDefaultDisplay().getMetrics(metrics);
     int mDensity = metrics.densityDpi;
 
     if (mDensity == 120) {
               settings.setDefaultZoom(ZoomDensity.CLOSE);
          }else if (mDensity == 160) {
               settings.setDefaultZoom(ZoomDensity.MEDIUM);
          }else if (mDensity == 240) {
               settings.setDefaultZoom(ZoomDensity.FAR);
          }
