我正在尝试发送带有磁盘映像的推文。我目前的代码如下:
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
final WebView.HitTestResult result = mWebView.getHitTestResult();
if (result.getType() == WebView.HitTestResult.IMAGE_TYPE ||
result.getType() == WebView.HitTestResult.SRC_IMAGE_ANCHOR_TYPE) {
//menu.setHeaderTitle(result.getExtra());
menu.add(0, 1, 0, "Save Image")
.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem menuItem) {
String DownloadImageURL = result.getExtra();
if(URLUtil.isValidUrl(DownloadImageURL)){
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(DownloadImageURL));
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
DownloadManager downloadManager = (DownloadManager) getActivity().getSystemService(Context.DOWNLOAD_SERVICE);
downloadManager.enqueue(request);
Toast.makeText(getContext(),"Image save successfully.",Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(getContext(),"Error to save image.",Toast.LENGTH_SHORT).show();
}
return false;
}
});
}
}
代码似乎运行,没有返回异常,但是未发布推文。感谢任何帮助或见解。

请查看ExceptionHandler的文档:https://github.com/linvi/tweetinvi/wiki/Exception-Handling。
ExceptionHandler.SwallowWebExceptions = false;
然后会引发异常。
