我想從Android手機應用程序發佈數據到PHP腳本。這是我正在使用的代碼。從Android應用程序發佈數據到PHP腳本
public class Upload extends Activity implements OnClickListener {
EditText joke;
Button upload;
AlertDialog alertDialog = new AlertDialog.Builder(this).create();
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.upload);
}
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.bUpload:
uploadJoke();
break;
}
}
private void uploadJoke() {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://xxxx/telejoke.php");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("username", "test"));
nameValuePairs.add(new BasicNameValuePair("joke", joke.getText().toString()));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
alertDialog.setTitle("Client Protocol Exception");
} catch (IOException e) {
alertDialog.setTitle("IOException");
}
}
}
然而,當我嘗試我的Android手機上運行它,它只是出現意外錯誤崩潰。幫助與此表示讚賞。

錯誤有東西與AlertDialog有關。當我在uploadJoke方法內部移動AlertDialog時,它將取出錯誤...但我仍然不認爲數據被髮布到我的PHP腳本中。 – moesef 2012-04-09 07:34:48
