我想在Android应用中取消FileAsyncHttpResponseHandler请求,但只有一个(不是全部)。有这些方法可用,但它们都没有取消请求。它一直持续到文件完全下载为止。
FileAsyncHttpResponseHandler fileAsyncHttpResponseHandler;
...get request...
fileAsyncHttpResponseHandler.deleteTargetFile();
fileAsyncHttpResponseHandler.onCancel();
fileAsyncHttpResponseHandler.sendCancelMessage();
请帮助我!!

我是所说的图书馆,你基本上有三种选择。
首先,从创建请求中获取AsyncHttpClient ahc = new AsyncHttpClient();
RequestHandle rh = ahc.get(context, url, fileResponseHandler);
rh.cancel();
,然后通过
AsyncHttpClient ahc = new AsyncHttpClient();
ahc.get(CurrentActivity.this, url, fileResponseHandler);
ahc.cancelRequests(CurrentActivity.this, boolean mayInterruptIfRunning);
其次,通过归属上下文取消请求
getTag()
第三,目前处于1.4.8快照(可能会在星期日发布1.4.8发布),在请求中放置一个TAG(或在ResponseHandler中实现String myTag = "my-long-identifier-such-as-uuid";
AsyncHttpClient ahc = new AsyncHttpClient();
RequestHandle rh = ahc.get(context, url, fileResponseHandler);
rh.setTag(myTag);
ahc.cancelRequestsByTAG(myTag, boolean mayInterruptIfRunning);
,并通过所述TAG取消)
AsyncHttpClient ahc = new AsyncHttpClient();
ahc.get(context, url, new FileAsyncHttpResponseHandler(){
// implement all methods
// override getTag() to identify request associated with this responseHandler
// for example return "url" for ability to cancel by request URL
@Override
public Object getTag() { return url; }
});
ahc.cancelRequestsByTAG(url, boolean mayInterruptIfRunning);
或通过从响应处理程序
实现getTag()L.Routing.control({ createMarker: function() { return null; } });
