解决方案

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

webview_pic.setWebViewClient(new myWebViewClient());

    private class myWebViewClient 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
            resetImg();
        }

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

   /**
     * 重置图片大小
     **/
    private void resetImg() {
        webview_pic.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';  " +
                "}" +
                "})()");
    }
