ConTct $ HttpPost無法轉換爲org.apache.http.HttpResponse

我試圖在類HttpPost中進行POST請求擴展AsyncTask實現HttpUriRequest。

當我書面方式：httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));這表明我在編譯時錯誤說：

The method setEntity(UrlEncodedFormEntity) is undefined for the type 
    ConTct.HttpPost. It says that I should make casting like this : ((HttpResponse) httppost).setEntity(new UrlEncodedFormEntity(nameValuePairs));

在運行時，它打印：「ConTct$HttpPost cannot be cast to org.apache.http.HttpResponse」。

請參見下文我的代碼：

改變你的AsyncTask類名從HttpPost其他任何事情。 Httppost是apache包中使用的預定義類 –

非常感謝！它似乎工作:) – user3111349

我與SIMpalm一個PHP開發人員，我想你可以按照這種解決方案。

而不是 HttpPost httppost = new HttpPost（url）;

使用此行

org.apache.http.client.methods.HttpPost httpPost = new org.apache.http.client.methods.HttpPost(url);

你能否向我解釋他們之間有什麼不同，爲什麼使用你的方式更好？ – user3111349

ConTct $ HttpPost無法轉換爲org.apache.http.HttpResponse
