無法將ConTct $ HttpPost強制轉換為org.apache.http.HttpResponse

Question

我試圖在HttpPost類中發出POST請求，擴展了AsyncTask實現HttpUriRequest。

當我寫的時候： httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 它顯示了編譯時間錯誤：

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，它顯示：“ ConTct$HttpPost cannot be cast to org.apache.http.HttpResponse ”。

請看下面我的代碼：

public class ConTct extends Activity implements OnClickListener, OnTouchListener{

    Button mButton;
    EditText mFullName, mEmail, mDialZone, mPhone;
    static WebView mWebView;
    static ProgressBar mProgressBar;

請拜托，幫我解決這個問題：）

我是SIMpalm的PHP開發人員，我認為您可以遵循此解決方案…。

而不是HttpPost httppost = new HttpPost（url）;

用這條線

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