我想連接到我使用httpPost請求創建的本地主機（WAMP）web服務。它一直失敗，並給出一個IllegalStateExecption。任何人都可以提供一些洞察問題？謝謝！HttpPost給Illegalstateexception
String songtext,artisttext;
HttpResponse response ;
EditText song;
EditText artist;
EditText party;
HttpPost post;
HttpClient client;
ArrayList<NameValuePair> nameValuePairs;
String URL = "http://10.0.2.2/GoDJ/index.php?r=request/create";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
song = (EditText)findViewById(R.id.songTitle);
artist = (EditText)findViewById(R.id.songArtist);
party = (EditText)findViewById(R.id.partyid);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void uploadToDB(View view)
{
//send user message
Context context = getApplicationContext();
CharSequence text = "Letting the DJ Know!!";
int duration = Toast.LENGTH_SHORT;

toast.show();

nameValuePairs.add(new BasicNameValuePair("title", song.getText().toString()));
