由于 Android 本身的限制,在 webview 中上传文件需要自行重载 `openFileChooser ()` 或者 `onShowFileChooser ()` 方法. 大致代码如下, 更完整的示例可以自行搜索 「安卓 webview 上传文件」. webview.setWebChromeClient (new WebChromeClient () { // For Android < 3.0 public void openFileChooser (ValueCallback valueCallback) { uploadMessage = valueCallback; openImageChooserActivity (); } // For
mWebView.setWebChromeClient(new WebChromeClient(){ public void openFileChooser(ValueCallback valueCallback) { mUploadCallBack = valueCallback; showFileChooser(); } public void openFileChooser(ValueCallback valueCallback, String acceptType) {
The- parameter for onReceiveValue will either be the filename- under which the file was saved, or null if saving the- file failed. */mWebView.saveWebArchive(String basename, boolean autoname, ValueCallback callback) 1.3 翻页、滚动及滚动条样式. 包括快速向上、向下翻页.

onActivityResult就是用来通知H5用户选择的文件地址,在这个方法里,用我们之前保存的ValueCallback对象,调用onReceiveValue方法,H5就可以收到我们传递给它的地址信息了! 以上就是本文的全部内容,希望对大家的学习有所帮助。

JSBridge的起源近些年,移动端普及化越来越高,开发过程中选用Native还是H5一直是热门话题。Native和H5都有着各自的优缺点,为了满足业务的需要,公司实际项目的开发过程中往往会融合两者进行Hybrid开发。Native和H5分处两地,看起来无法联系,那么如何才能让双方协同实现功能呢?这时我们想到了

J'essaie d'utiliser la nouvelle méthode evaluateJavascript dans Android 4.4, mais tout ce que j'obtiens est un résultat nul: . webView1.evaluateJavascript("return \"test\";", new ValueCallback() { @Override public void onReceiveValue(String s) { Log.d("LogName", s); // Log is written, but s is always null } });
*/ @SystemApi @Deprecated public void openFileChooser(ValueCallback uploadFile, String acceptType, String capture) { uploadFile.onReceiveValue(null); } 解決方案也很簡單,直接不混淆 openFileChooser() 就好了。

Variable Value Callback ¶ When a value changes continuously, such as the system time, updating the value in a tight loop would take up a lot of resources. Value callbacks allow to synchronize a variable value with an external representation. They attach callbacks to the variable that are executed before every read and after every write operation.

Pastebin is a website where you can store text online for a set period of time. 如果需要网页获取返回值还需要网页调用安卓 @JavaScriptInterface 注解的方法才可以。. Android 4.4以上调用webview.evaluateJavascript (javascript:方法名(参数),new ValueCallback {. public void onReciveValue (String value) {} })来实现调用js方法,同时能够获取网页返回的数据。.
After that, you need to write code for showing "file chooser". Just copy the below code and paste it into your WebChromeClient function. By the way, you can see below code contain "web" is my variable name, I have retrieved and stored my Webview from activity_main.xml.you need to replace that variable "web" with your variable name.
