Question

有没有办法找到一个请求是否仍在执行中？如果一个请求仍在执行但尚未完成，我想取消请求。

// fetch Results
private void fetchResults(CharSequence s) {

    if (s.toString().length() > 3){
        mSearchResult.clear();
        mAdapter.notifyDataSetChanged();

        HashMap hashMap = new HashMap();
        hashMap.put("q", s.toString());

        PrefManager pref = new PrefManager(SearchActivity.this);
        String token = pref.getAuthenticationToken();

        Call<AppointmentsModel> call = mAPIService.getResults("Token " + token, hashMap);

        call.enqueue(new Callback<AppointmentsModel>() {
            @Override
            public void onResponse(Call<AppointmentsModel> call, Response<AppointmentsModel> response) {
                List<Result> resultList = response.body().getResult();

                mSearchResult.addAll(resultList);
                mAdapter.notifyDataSetChanged();

                showNoSearchResults();
            }

            @Override
            public void onFailure(Call<AppointmentsModel> call, Throwable t) {
                if (BuildConfig.DEBUG) Log.d(TAG, "onFailureRetrofit: " + t.toString());
            }
        });
    }else{
        showNoSearchResults();
    }
}

我想在一个请求已经起作用时取消通话。你能告诉我我应该在哪里做同样的事情。谢谢。

将其设置为全局：

Call<AppointmentsModel> call;

public void afterTextChanged (Editable s) {
if(call != null && call.isExecuted()) {
  call.cancel();
}else{
//Your network call
}
}

当一个请求仍在执行时，如何取消改造请求？
