尝试使用“WebClientListener”并覆盖“shouldOverrideUrlLoading”。

webView.setWebViewClient(new WebClientListener());

和private class WebClientListener extends WebViewClient { //other callback...... @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { //Intercept the url you specified in this method. //e.g. Define a specified url like "http://yourhost.com/shareToFacebook" //in your html and when you cathch this url, use the facebook's sdk to share, //and return "true" to tell the webview to handle such url yourself. // //If you want to open the browser outside,you can use: //Uri uri = Uri.parse(url); //Intent intent = new Intent(Intent.ACTION_VIEW, uri); //startActivity(intent); } }

如果您只想在webview中上传照片等文件，可以尝试

webView.setWebChromeClient(new WebChromeClient());

覆盖界面的onShowFileChooser（棒棒糖后）和openFileChooser（prelolipop）。
