I’m passing two strings between two activities and for some strange reason, the strings aren’t being passed. I’ve done all the correct protocols and nothing seems to work, despite tinkering around with the code for several hours, I’m sure it’s an simple solution, but I have no clue, what’s so ever.
1st Class:
public class LogIn extends Activity implements OnClickListener {
Button ok, back, exit;
TextView result;
EditText pword;
String password;
EditText uname;
String username;
/** 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);
}
//create bracket.
public void postLoginData() {
uname = (EditText) findViewById(R.id.txt_username);
uname.getText().toString();
pword = (EditText) findViewById(R.id.txt_password);
pword.getText().toString();
Bundle basket = new Bundle();
basket.putString("keypass", password);
basket.putString("keyuname", username);
Intent a = new Intent(LogIn.this, ChatService.class );
a.putExtras(basket);
startActivity(a);
// 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://gta5news.com/login.php");
try {
// Add user name and password
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("HttpPost(Login)", "Execute HTTP Post Request(Login 1)");
HttpResponse response = httpclient.execute(httppost);
String str = inputStreamToString(response.getEntity().getContent())
.toString();
Log.w("HttpPost", str);
if (str.toString().equalsIgnoreCase("true")) {
Log.w("HttpPost(Login2)", "TRUE");
result.setText("Login successful");
Intent login = new Intent(LogIn.this, ChatService.class);
startActivity(login);
}else {
Log.w("HttpPost(Login(3)", "FALSE");
result.setText(str);
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
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;
}
public void onClick(View view) {
if (view == ok) {
postLoginData();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(pword.getWindowToken(), 0);
}
// Click end
}
// if statement
}
// class ends here
2nd class:
public class ChatService extends ListActivity {
/** Called when the activity is first created. */
BufferedReader in = null;
String data = null;
List headlines;
List links;
String GotPass;
String GotUname;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//get strings
Bundle gotData = getIntent().getExtras();
if(gotData !=null) {
GotPass = gotData.getString("keypass");
GotUname = gotData.getString("keyuname");
try {
//listview method
ContactsandIm();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
CheckLogin();
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
private void CheckLogin() throws UnsupportedEncodingException {
// posts login data from "LogIn" class
// 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://gta5news.com/login.php");
try {
// Add user name and password
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("username", GotUname));
nameValuePairs.add(new BasicNameValuePair("password", GotPass));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
Log.w("HttpPost(Login)", "Execute HTTP Post Request(ChatService 1)");
HttpResponse response = httpclient.execute(httppost);
String str = inputStreamToString(response.getEntity().getContent())
.toString();
Log.w("HttpPost", str);
if (str.toString().equalsIgnoreCase("true")) {
Log.w("HttpPost(ChatService 2)", "TRUE");
// make toast if str.equals("True")
Toast.makeText(getApplicationContext(), "Yayayaya, loged in", Toast.LENGTH_LONG );
}else {
Log.w("HttpPost(ChatService 3", "FALSE");
Toast.makeText(getApplicationContext(), "failed", Toast.LENGTH_LONG);
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
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;
}
public void ContactsandIm() throws URISyntaxException,
ClientProtocolException, IOException {
headlines = new ArrayList();
// TODO Auto-generated method stub
BufferedReader in = null;
String data = null;
HttpClient get = new DefaultHttpClient();
URI website = new URI("http://www.gta5news.com/test.php");
HttpGet webget = new HttpGet();
webget.setURI(website);
HttpResponse response = get.execute(webget);
Log.w("HttpPost", "Execute HTTP Post Request");
in = new BufferedReader(new InputStreamReader(response.getEntity()
.getContent()));
StringBuffer sb = new StringBuffer("");
String l ="";
String nl ="";
while ((l =in.readLine()) !=null) {
sb.append(l + nl);
}
in.close();
data = sb.toString();
if(data.contains("null"));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
headlines.add(data);
ArrayAdapter adapter = new ArrayAdapter(this,
android.R.layout.simple_list_item_1, headlines);
setListAdapter(adapter);
}
// end bracket for "ContactsandIm"
}
Try this way.
