Android适配利用webview加载后图片显示过大的问题解决

 webView.getSettings().setJavaScriptEnabled(true);//支持javascript

 webView.setWebViewClient(new ArticleWebViewClient());

 private class ArticleWebViewClient extends WebViewClient {

  @Override
  public void onPageFinished(WebView view, String url) {
   super.onPageFinished(view, url);
   //重置webview中img标签的图片大小
   imgReset();
  }

  @Override
  public boolean shouldOverrideUrlLoading(WebView view, String url) {
   view.loadUrl(url);
   return true;
  }
 }

 /**
  * 对图片进行重置大小，宽度就是手机屏幕宽度，高度根据宽度比便自动缩放
  **/
 private void imgReset() {
  webView.loadUrl("javascript:(function(){" +
    "var objs = document.getElementsByTagName('img'); " +
    "for(var i=0;i<objs.length;i++) " +
    "{"
    + "var img = objs[i]; " +
    " img.style.maxWidth = '100%'; img.style.height = 'auto'; " +
    "}" +
    "})()");
 }
