公共类AndroidLogin扩展活动实现OnClickListener {

按钮OK，背部，退出; TextView结果;

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    // Login button clicked 
    ok = (Button)findViewById(R.id.btn_login); 
    ok.setOnClickListener(this); 

    result = (TextView)findViewById(R.id.lbl_result); 

} 

public void postLoginData() { 
    // Create a new HttpClient and Post Header 
    HttpClient httpclient = new DefaultHttpClient(); 

    /* login.php returns true if username and password is equal to saranga */ 
    HttpPost httppost = new HttpPost("http://www.gowdanar.com:2095/"); 

    try { 
     // Add user name and password 
    EditText uname = (EditText)findViewById(R.id.txt_username); 
    String username = uname.getText().toString(); 

    EditText pword = (EditText)findViewById(R.id.txt_password); 
    String password = pword.getText().toString(); 

     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 
     nameValuePairs.add(new BasicNameValuePair("username", username)); 
     nameValuePairs.add(new BasicNameValuePair("password", password)); 
     httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

     // Execute HTTP Post Request 
     Log.w("SENCIDE", "Execute HTTP Post Request"); 
     HttpResponse response = httpclient.execute(httppost); 

     String str = inputStreamToString(response.getEntity().getContent()).toString(); 
     Log.w("SENCIDE", str); 

     if(str.toString().equalsIgnoreCase("true")) 
     { 
     Log.w("SENCIDE", "TRUE");

} 

private StringBuilder inputStreamToString(InputStream is) { 
String line = ""; 
StringBuilder total = new StringBuilder(); 
// Wrap a BufferedReader around the InputStream 
BufferedReader rd = new BufferedReader(new InputStreamReader(is)); 
// Read response until the end 
try { 
    while ((line = rd.readLine()) != null) { 
    total.append(line); 
    } 
} catch (IOException e) { 
    e.printStackTrace(); 
} 
// Return full string 
return total; 
} 

@Override 
public void onClick(View view) { 
    if(view == ok){ 
    postLoginData(); 
    } 
} 

}

把你的HTTP请求中AsynTask并获得onPostExecute（响应）这样的方法。

私有类调用getResult扩展的AsyncTask {

@Override 
    protected String doInBackground(String... urls) { 
     Log.v(TAG + ".doInBackground", "doInBackground method call"); 
     String response1 = null; 

    /* for (String url : urls) { 
      WebHelper webHelper = new WebHelper(); 
      response = webHelper.getResult(url); 
      Log.v(TAG+".doInBackground", "json response is:" + response); 
     }*/ 

      HttpClient httpclient = new DefaultHttpClient(); 
      HttpPost httppost = new HttpPost(""http://www.gowdanar.com:2095/""); 
      // Log.d("response", "WORKING"); 
      try { 


       List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); 

       nameValuePairs.add(new BasicNameValuePair("username", username)); 
       nameValuePairs.add(new BasicNameValuePair("password", password)); 

       httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
       HttpResponse response = httpclient.execute(httppost); 
       InputStream is = response.getEntity().getContent(); 
       WebHelper webHelper = new WebHelper(); 
       response1 = webHelper.convertStreamToString(is); 
       Log.v(TAG+".doInBackground", "json response is:" + response1); 

     } catch (ClientProtocolException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 


     return response1; 


    } 

    @Override 
    protected void onPostExecute(String result) { 

     Log.v(TAG + ".onPostExecute", "onPostExecute method call"); 
     dialog.dismiss(); 
     Log.v(TAG+".onPostExecute", "json response is:" + result); 


     if(result!=null){ 

      try { 
       //JSONTokener tokener = new JSONTokener(result); 
       JSONObject resultObjct = new JSONObject(result); 
       String user_id=resultObjct.getString("User_ID"); 


       } 

       } catch (JSONException e) { 
       e.printStackTrace(); 
       } 
       catch (Exception e) { 
       e.printStackTrace(); 
       } 
      } 

    } 
}
