I want to upload text data to Http. I have layout with a Button and a EditText. When i click button, my text data on edittext will upload to my website.
sendButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
// get the message from the message text box
String msg = msgTextField.getText().toString();
// make sure the fields are not empty
if (msg.length() > 0) {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
mywebsite...);
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
2);
nameValuePairs
.add(new BasicNameValuePair("id", "12345"));
nameValuePairs.add(new BasicNameValuePair("message",
msg));
httppost.setEntity(new UrlEncodedFormEntity(
nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
msgTextField.setText(""); // clear text box
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
} else {
// display message if text fields are empty
Toast.makeText(getBaseContext(), "All field are required",
Toast.LENGTH_SHORT).show();
}
}
});
On AndroidManifest
<uses-permission android:name="android.permission.INTERNET" />
