百度过各种办法，就这个有效，亲测。

webView.getSettings().setJavaScriptEnabled(true);

webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                imgReset();//使用js的方法
            }

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

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
            }
        });
    }
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.width = '100%';   "
                + "    img.style.height = 'auto';   "
       }
