android下让webview支持网页文件上传

android开发，webview 对网页的，file upload进行支持，代码如下：

全局

private ValueCallback<Uri> mUploadMessage;

private final static int FILECHOOSER_RESULTCODE = 1;

webview进行处理

webview.setWebChromeClient(new WebChromeClient() {

      super.onProgressChanged(view, progress);

   }

 

   // For Android 3.0+

   public void openFileChooser(ValueCallback<Uri> uploadMsg,String acceptType) {

      if (mUploadMessage != null)

         return;

      mUploadMessage = uploadMsg;

      Intent i = new Intent(Intent.ACTION_GET_CONTENT);

      i.addCategory(Intent.CATEGORY_OPENABLE);

      i.setType("image/*");

      startActivityForResult(Intent.createChooser(i, "选择文件"),FILECHOOSER_RESULTCODE);

   }

 

   // For Android < 3.0

   public void openFileChooser(ValueCallback<Uri> uploadMsg) {

      openFileChooser(uploadMsg, "");

   }

 

   // For Android > 4.1.1

   public void openFileChooser(ValueCallback<Uri> uploadMsg,String acceptType, String capture) {

      openFileChooser(uploadMsg, acceptType);

   }

});

对选择操作的返回事件进行处理

@Override

protected void onActivityResult(int requestCode, int resultCode,Intent intent) {

   if (requestCode == FILECHOOSER_RESULTCODE) {

      if (null == mUploadMessage)

         return;

      Uri result = intent == null || resultCode != RESULT_OK ? null: intent.getData();

      mUploadMessage.onReceiveValue(result);

      mUploadMessage = null;

   }

}

经以上三步，就支持文件上传了。
