Android WebView网页文件上载选择器不工作

使用这个,//we do open selector window for the url having“google”in the uri,you can change that:

webView.setWebViewClient(new WebViewClient() {      
                ProgressDialog progressDialog;

                //If you will not use this method url links are open in new brower not in webview
                public boolean shouldOverrideUrlLoading(WebView view, String url) {              

                    // Check if Url contains ExternalLinks string in url 
                    // then open url in new browser
                    // else all webview links will open in webview browser
                    if(url.contains("google")){ 

                        // Could be cleverer and use a regex
                        //Open links in new browser
                        view.getContext().startActivity(
                                new Intent(Intent.ACTION_VIEW, Uri.parse(url)));

                        // Here we can open new activity

                        return true;

                    } else {

                        // Stay within this webview and load url
                        view.loadUrl(url); 
                        return true;
                    }

                }



                //Show loader on url load
                public void onLoadResource (WebView view, String url) {

                    // if url contains string androidexample
                    // Then show progress  Dialog
                    if (progressDialog == null && url.contains("androidexample") 
                            ) {

                        // in standard case YourActivity.this
                        progressDialog = new ProgressDialog(ShowWebView.this);
                        progressDialog.setMessage("Loading...");
                        progressDialog.show();
                    }
                }

                // Called when all page resources loaded
                public void onPageFinished(WebView view, String url) {

                    try{
                        // Close progressDialog
                        if (progressDialog.isShowing()) {
                            progressDialog.dismiss();
                            progressDialog = null;
                        }
                    }catch(Exception exception){
                        exception.printStackTrace();
                    }
                }

            });
