这是代码，我使用HTTP交HTTP POST给予非法状态异常
public void postData() {
//DineOutActivity doa = null;
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("192.168.1.112/andro/index.php/androctrl/test/");
try {
//food item
Spinner spinner = (Spinner) findViewById(R.id.spinner1);
String fooditem = spinner.getSelectedItem().toString();
TextView mDateDisplay = (TextView)findViewById(R.id.textView2);
String Date = mDateDisplay.toString();
TextView mTimeDisplay = (TextView)findViewById(R.id.textView4);
String Time = mTimeDisplay.toString();
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("fooditem", "fooditem"));
nameValuePairs.add(new BasicNameValuePair("Date", "Date"));
nameValuePairs.add(new BasicNameValuePair("Time", "Time"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
String str = inputStreamToString(response.getEntity().getContent()).toString();
Log.w("ADPORTAL", str);
HttpStatus status;
if(str.toString().equalsIgnoreCase("false"))
{Toast.makeText(getBaseContext(), str, Toast.LENGTH_LONG).show();
//result.setText("You are not registerd please register"
}
else
{Toast.makeText(getBaseContext(), str, Toast.LENGTH_LONG).show();}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}
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;
我使用mTimeDisplay [文本视图2]如从TimePicker对话框的值。 和mDateDisplay [Texview4]作为DatePicker对话框中的值。
以下是我已经使用postData()

我有排队的Exception在postData方法
HttpResponse response = httpclient.execute(httppost);
的logcat中的例外是我的全部代码：
