The radio button which I previously selected is not selected when the text is changed after i click on next button. Please help

You should replace:
int selectedId = s_rbgrp.getCheckedRadioButtonId();
selectedRbButton = (RadioButton) findViewById(selectedId);
selectedRbButton.setChecked(false);
with:
s_rbgrp.clearCheck();

I don't understand why it keeps on saying Response is : Wrong. Tired of spending almost a day .. I am here seeking help.
Excuse me if my questions seems naive.
Thank you in advance.

try below code:-
HttpResponse httpResponse = httpClient.execute(httpPost);
if (httpResponse != null)
{
InputStream in = httpResponse.getEntity().getContent();
result = ConvertStreamToString.convertStreamToString(in);
// System.out.println("result =>" + result);
}
convertStreamToString method
public String convertStreamToString(InputStream is)
{
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try
{
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
}
catch (IOException e)
{
e.printStackTrace();
}
finally
{
try
{
is.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
return sb.toString();
}
do not under stand :-
HttpResponse httpResponse = httpClient.execute(httpPost); // getting response from server
// where you use this response and why using below line or whats the benefit of below line
ResponseHandler<String> responseHandler = new BasicResponseHandler();
final String response = httpClient.execute(httpPost, responseHandler);

Hope this helps you!!!
If its not working please let me know i will try to help more...

Try using Volley if not. It's faster than the ussual HTTP connection classes.
Example:
RequestQueue queue = Volley.newRequestQueue(this);
String url = "url";
JSONObject juser = new JSONObject();
try {
juser.put("locationId", locID);
juser.put("email", email_input);
juser.put("password", password_input);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST, url, juser, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
// TODO Auto-generated method stub
txtDisplay.setText("Response => "+response.toString());
findViewById(R.id.progressBar1).setVisibility(View.GONE);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub
}
});
queue.add(jsObjRequest);

Like #Andrew T suggested , I am posting my solution.
The mysql_error()helped me debug the issue. mysql_error() displayed in the Logcat that "register table is not found" .. but the table name is registers. I was missing "s" at the end.
$fullname = $_POST['fullname'];
$email = $_POST['email'];
$password = $_POST['password'];
$insert_data = "INSERT INTO registers(id, fullname, email, password)
Values ('','$fullname', '$email', '$password')";
$insert_result = mysql_query($insert_data) or die(mysql_error());
//echo "Signed Up";
if($insert_result){
echo "Signed Up";
}
else{
echo "wrong!";
}
Everything worked perfect after that. Again, thank you all for your time and solutions. Everyone's suggestions are great, but I can not accept any answer at this point.. sorry:(

Retrieving data in offline mode

I have some data on the internet for each specific longitude and latitude. If a user inputs a particular latitude and longitude, the data is downloaded from the web and then used in further calculation. I want to save that data so that the next time the user inputs the same latitude and longitude, It bypasses the web connectivity and proceeds with the existing data.
My Input Class:
public class OpTilt extends Activity implements OnClickListener {
EditText latitude, longitude;
Button go;
String data1, data2, link, link1;
double dat1, dat2;
TextView gps;
SharedPreferences dataurl;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.optilt);
initialize();
go.setOnClickListener(this);
}
private void initialize() {
// TODO Auto-generated method stub
go = (Button) findViewById(R.id.loaddata);
latitude = (EditText) findViewById(R.id.lat);
longitude = (EditText) findViewById(R.id.lon);
dataurl = getSharedPreferences("url", 0);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
data1 = longitude.getText().toString();
data2 = latitude.getText().toString();
dat1 = Double.parseDouble(data1);
dat2 = Double.parseDouble(data2);
link = ("http://www.otilt.com/api.php?lat=" + dat2 + "&lon=" + dat1);
SharedPreferences.Editor editor = dataurl.edit();
editor.putString("key", link);
editor.commit();
Intent i = new Intent(OpTilt.this, DataRetrieve.class);
startActivity(i);
}
}
My Parsing Class:
public class DataRetrieve extends Activity {
HttpClient client;
String URL, re, element;
JSONObject json, getjson;
int i, j, statusCode;
HttpGet httpget;
HttpResponse response;
HttpEntity entity;
InputStream is;
BufferedReader reader;
StringBuilder sb, sb1;
WakeLock w;
SharedPreferences getinput, passjson;
ProgressDialog pd;
#Override

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
w = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK, "tag");
super.onCreate(savedInstanceState);
w.acquire();
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.dataretrieve);
// Bundle gotBasket = getIntent().getExtras();
// URL = gotBasket.getString("key");
getinput = getSharedPreferences("url", 0);
URL = getinput.getString("key", null);
Read r = new Read();
r.execute();
}
public class Read extends AsyncTask<String, Integer, String> {
#Override
protected void onPreExecute() {
pd = new ProgressDialog(DataRetrieve.this);
pd.setTitle("Processing...");
pd.setMessage("Please wait.");
pd.setCancelable(false);
pd.setIndeterminate(true);
pd.show();
}
#Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
re = null;
is = null;
json = null;
try {
client = new DefaultHttpClient();
httpget = new HttpGet(URL);
response = client.execute(httpget);
entity = response.getEntity();
is = entity.getContent();
statusCode = response.getStatusLine().getStatusCode();
} catch (Exception e) {
statusCode = -1;
Log.e("log_tag", "Erro http " + e.toString());
}
if (statusCode == 200) {
try {
reader = new BufferedReader(new InputStreamReader(is,
"UTF-8"), 8);
sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
re = sb.toString();
} catch (Exception e) {
Log.e("log_tag", "Erro conversão " + e.toString());
}
}
return re;
}
#Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
pd.dismiss();
try {
json = new JSONObject(result);
getjson = json.getJSONObject("Solar");
String H[] = new String[getjson.length()];
for (i = 0, j = 1; i < getjson.length(); i++, j++) {
H[i] = getjson.getString("" + j);
}
Bundle bundle = new Bundle();
bundle.putStringArray("key1", H);
Intent f = new Intent(DataRetrieve.this, Calculator.class);
f.putExtras(bundle);
startActivity(f);
}
catch (JSONException e) {
Log.e("log_tag", "Erro dados " + e.toString());
}
}
}
#Override

// TODO Auto-generated method stub
super.onPause();
w.release();
finish();
}
}
So, how can I achieve my goal?

elementarytxtview is not initialized before you try to show it via Toast. At first you need to put some value in it.

I'm not a 100% sure of what you mean.
But if you want to access variables easily between classes, you should make the String elementarytxtview; public static
Thereby: public static String elementarytxtview;
What that means is basically that the variable is shared and can be used between all classes. Just by writing HomeMenu.elementarytxtview; in your case.

You are showing the Toast in the onCreate method which runs before your parseJSONData() method. You haven't initialized String elementarytxtview therefore it will show null because you only declared the variable.
