Pass an EditText input from one class to another in Android

Pass an EditText input from one class to another in Android - java

I've seen more questions like this but didn't manage to make any sense of them or they didn't apply to my problem, so here goes.
I have an Activity that allows you to login and another where you send POST and GET requests and so on, using your login credentials.
mainActivity:
public class MainActivity extends Activity
{
private String username;
private String password;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText usernameField = (EditText) findViewById(R.id.enterUsername);
final EditText passwordField = (EditText) findViewById(R.id.enterPassword);
Button startButton = (Button) findViewById(R.id.startButton);
startButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view)
{
username = usernameField.getText().toString();
password = passwordField.getText().toString();
Intent myIntent = new Intent(view.getContext(), HttpGetPost.class);
startActivityForResult(myIntent, 0);
}
});
}
public String getUser() { return this.username; }
public String getPassword() { return this.password; }
}
HttpGetPost:
public class HttpGetPost extends Activity
{
private MainActivity mainProxy = new MainActivity();
private Button postButton;
private Button getButton;
private Button getMeasureButton;
private Button getDevicesButton;
private String access_token;
private String refresh_token;
private String device_list;
private String expires_in;
private String getRequest;
private static final String TAG = "MyActivity";
private static final String USER_AGENT = "Mozilla/5.0";
private String clientID = some_id;
private String clientSecret = some_secret;
private String user = mainProxy.getUser();
private String pass = mainProxy.getPassword();
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_http);
Log.v(TAG, "mainProxy.username: "+user);
Log.v(TAG, "mainProxy.password: "+pass);
postButton = (Button) findViewById(R.id.postButton);
postButton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
new sendPost().execute("");
}
});
}
private class sendPost extends AsyncTask<String, Void, String>
{
#Override
protected String doInBackground(String... params)
{
try
{
String url = some_url;
URL obj = new URL(url);
HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();
//add request header
con.setRequestMethod("POST");
con.setRequestProperty("User-Agent", USER_AGENT);
con.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
String urlParameters = "grant_type=password&client_id=" +clientID +"&client_secret="
+clientSecret +"&username=" +user +"&password=" +pass;
// Send post request
con.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
int responseCode = con.getResponseCode();
Log.v(TAG, "\nSending 'POST' request to URL : " + url);
Log.v(TAG, "Post parameters : " + urlParameters);
Log.v(TAG, "Response Code : " + responseCode);
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
//print result
Log.v(TAG, response.toString());
if (responseCode == 200)
{
access_token = response.substring(17, 74);
refresh_token = response.substring(93,150);
expires_in = response.substring(165, 170);
getRequest = "http://api.netatmo.net/api/getuser?access_token=" +access_token + " HTTP/1.1";
Log.v(TAG, "access token: " +access_token);
Log.v(TAG, "refresh token: " +refresh_token);
Log.v(TAG, "expires in: " +expires_in);
}
}
catch(Exception e){
e.printStackTrace();
}
return "";
}
protected void onPostExecute(String result) {
Toast.makeText(getApplicationContext(), "ENDED", Toast.LENGTH_LONG).show();
}
}
}
When I print out the username and password in the second class, they both return null, and the POST request fails.

To clarify what I meant in the comment at jbihan's answer:
I'm updating your code:
First revision:
Button startButton = (Button) findViewById(R.id.startButton);
startButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view)
{
username = usernameField.getText().toString();
password = passwordField.getText().toString();
Intent myIntent = new Intent(view.getContext(), HttpGetPost.class);
// ADDITION
myIntent.putExtra("username", username);
myIntent.putExtra("password", password);
// END ADDITION
startActivityForResult(myIntent, 0);
}
});
Second revision:
postButton = (Button) findViewById(R.id.postButton);
// ADDITION
final String user = getIntent().getStringExtra("username");
final String password = getIntent().getStringExtra("password");
// END ADDITION
postButton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
// EDITED
new sendPost().execute(user, password);
}
});
Third revision:
private class sendPost extends AsyncTask<String, Void, String>
{
#Override
protected String doInBackground(String... params)
{
// ADDITION
String user = params[0];
String password = params[1];
// END ADDITION
// use them in the request
// rest of code...
}
}
Please consider using constants for "username" and "password" keys.

You should pass the username and password to your activity using the putExtra methods of the intent :
Intent myIntent = new Intent(view.getContext(), HttpGetPost.class);
myIntent.putExtra("username", username);
myIntent.putExtra("password", pasword);
startActivityForResult(myIntent, 0);
In your second activity, in onCreate() (after setContentView for example), you can retrieve them using getXXExtras :
Intent intent = getIntent();
String username = intent.getStringExtra("username");
String password = intent.getStringExtra("password");

Try to use extras:
Intent myIntent = new Intent(view.getContext(), HttpGetPost.class);
myIntent.putExtra("username", username);
myIntent.putExtra("password", password);
startActivityForResult(myIntent, 0);
In the other actvity(your HttpGetPost)
String user = getIntent().getStringExtra("username");
String password = getIntent().getStringExtra("password");

Here is a nice tutorial about the proper use of Intents.
Try this call of the HttpGetPost Activity:
Intent myIntent = new Intent(this, HttpGetPost.class);
myIntent.putExtra("username", username);
myIntent.putExtra("password", password);
startActivity(myIntent);
With this you pass the right Context in the Intent constructor. Put the data in the Intent which you wanna send to the Activity. The next point is to not call startActivityForResult(), which is used to call an Activity, make some calculation and send the results back to the requesting Activity.
Now get the data out of the Intent in the HttpGetPost Activity like this in your onCreate and save it to a field:
getIntent().getExtras().getString("username");
getIntent().getExtras().getString("password");

You don't need
private MainActivity mainProxy = new MainActivity();
in HttpGetPost. It will create a new MainActivity, which is not the original one which start HttpGetPost.
You can use extras to send data across intents. Here is my solution:
Put this in MainActivity
Intent myIntent = new Intent(view.getContext(), HttpGetPost.class);
myIntent.putExtra(HttpGetPost.KEY_USERNAME, username);
myIntent.putExtra(HttpGetPost.KEY_PASSWORD, password);
startActivityForResult(myIntent, 0);
This is for HttpGetPost, KEY_USERNAME and KEY_PASSWORD can be used to store extra key, so that you can avoid typo.
public static final String KEY_USERNAME = "username"; // or whatever you like for key
public static final String KEY_PASSWORD = "password"; // or whatever you like for key
private String user; // instead of private String user = mainProxy.getUser();
private String pass; // instead of private String pass = mainProxy.getPassword();
Put this in onCreate of HttpGetPost to get the data from intent
Intent intent = getIntent();
user = intent.getStringExtra(KEY_USERNAME);
pass = intent.getStringExtra(KEY_PASSWORD);
Here is the official document for intent.

Android code to connect PHP response changed to null

I'm facing problem in getting a response back in android from PHP.
First, it gets the right response in try then I don't know what cause problem it goes to catch and change response to null. My PHP files are perfectly working I tested them by giving default values.
Below is the code:
This class is used to connect to server and send data to PHP:

Error with "null" EditText applying to end of URL in Android Studio

So each time I run the app, type in an ID and hit submit; the end result come outs with null as the ID.
For example: I want to type in 12345 it should go to http://www.hiddenlink.com/12345 but instead it goes to http://www.hiddenlink.com/null
Here's my code:
public class SearchActivity extends Activity {
Button btnSearchStudent;
String studentID;
private String url = "http://www.hiddenlink.com/" + studentID; // This is test SID just to confirm connection
private static final String TAG_ALLRECORDS = "Objects";
private static final String TAG_ENAME = "emer_name1";
private static final String TAG_EPHONE1 = "emer_Phone1";
private static final String TAG_EPHONE2 = "emer_Phone2";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
EditText txtStudentID = (EditText) findViewById(R.id.txtStudentID);
studentID = txtStudentID.getText().toString();
btnSearchStudent = (Button) findViewById(R.id.btnSearchSID);
btnSearchStudent.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(SearchActivity.this, SearchResults.class);
startActivity(intent);
new JSONParse().execute();
}
});
}
private class JSONParse extends AsyncTask<Void, Void, Void> {
private ProgressDialog pDialog;
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(SearchActivity.this);
pDialog.setMessage("Connection Test: Logging into Student Database...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
// Login to APIs
#Override
protected Void doInBackground(Void... args) {
String _username = "hidden";
String _password = "hidden123";
String content = MyHttpURLConnection.getData(url, _username, _password);
try {
// Getting JSON Object from URL Content
JSONObject json = new JSONObject(content);
JSONArray jsonArray = json.getJSONArray(TAG_ALLRECORDS);
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject c = jsonArray.getJSONObject(i);
// Storing JSON item in a Variable
String emer_name1 = c.getString(TAG_ENAME);
String emer_Phone1 = c.getString(TAG_EPHONE1);
String emer_Phone2 = c.getString(TAG_EPHONE2);
// Adding value HashMap key => value
HashMap<String, String> add = new HashMap<String, String>();
add.put(TAG_EPHONE1, emer_Phone1);
add.put(TAG_ENAME, emer_name1);
add.put(TAG_EPHONE2, emer_Phone2);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
}
}

String studentID;
private String url = "http://www.hiddenlink.com/" + studentID;
studentID hasn't been initialized here yet, and so its value is null. Remove the + studentID part and add the studentID when you have set it a value.

#Emd4600 is right
You must add the value only after edittext has been initialized and you have some value in it...
To do so do this just define the "url" var, but don't add student id to it:
private String url = "http://www.hiddenlink.com/%s";
And later when you get edittext do this add the id to url:
EditText txtStudentID = (EditText) findViewById(R.id.txtStudentID);
[... more code...]
String realUrl = String.format(url, txtStudentID.getText().toString(););
That's about it.

Why don't you just change your code with:
private String baseUrl = "http://www.hiddenlink.com/";
private String url = "";
btnSearchStudent.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
url = baseUrl + txtStudentID.getText().toString();
new JSONParse().execute();
}
});
I'm missing the sense of reloding the whole Activity

You aren't re-assinging studentID after you click the button, hence it stays null because of its basic initialization:
btnSearchStudent.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// re-init the student id field
CharSequence input = txtStudentId.getText();
if (input != null) {
studentID = input.toString();
}
Intent intent = new Intent(SearchActivity.this, SearchResults.class);
startActivity(intent);
new JSONParse().execute();
}
});
Code Standard
You should also label your global variables as m<Name> this is standard to signify that the field is a class member variable
Recommendation
Another way you can do this is to pass in the String into the execute() method of the AsyncTask, that way you can pass in multiple arguments instead of just one, but this will require that you change your AsyncTask to handle multiple queries.

As Emd4600 wrote, your String studentID is not initialized at the moment. You probably want to build and run your request when the user hits btnSearchStudent. To do so, you'll have to append the content of txtStudentId in the onClick listener of your button.

I used what Filnik said and it worked.
Thanks for all the input guys, much appreciated.
Filnik:
private String baseUrl = "http://www.hiddenlink.com/";
private String url = "";
btnSearchStudent.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
url = baseUrl + txtStudentID.getText().toString();
new JSONParse().execute();
}
});

Retrieve email belonging to username in android

I have to develop a login form android application.Here, i have to enter the username and password. If it is correct, fetch the email belonging to the username and display it in the textview and if the username and password is wrong, display login failed message.
This is my webservice code:
public class Login {
public String authentication(String username,String password) {
String retrievedUserName = "";
String retrievedPassword = "";
String retrievedEmail = "";
String status = "";
try {
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/xcart-432pro","root","");
PreparedStatement statement = con.prepareStatement("SELECT * FROM xcart_customers WHERE login = '"+username+"'");
ResultSet result = statement.executeQuery();
while(result.next()){
retrievedUserName = result.getString("login");
retrievedPassword = result.getString("password");
retrievedEmail = result.getString("email");
}
if(retrievedUserName.equals(username)&&retrievedPassword.equals(password)&&!(retrievedUserName.equals("") && retrievedPassword.equals(""))){
status = "Success";
}
else {
status = "Login fail!!!";
}
}
catch(Exception e){
e.printStackTrace();
}

If the login is success, it will have to display the email on textview. How can i do that?

You can use asy task to do this,
in doInBackground
Do your login operations. Asyctask makes this operation in another task.
when complated in onPostExecute
show the success message. But you need to use runOnUiThread because you cant reach ui controls from non ui thread.
private class loginTask extends AsyncTask<URL, Integer, int> {
protected Long doInBackground(URL... urls) {
// start login process
return 1;
}
protected void onPostExecute(int result) {
_activity.runOnUiThread(new Runnable() {
#Override
public void run() {
textview.setText("login success");
}
});
}
}

Response received from web service is null

I am sending details to be stored in a database using a web service using KSOAP. I have used visual studio to create the web service. The web service works fine. A string will be returned when the details have been inserted into the database. The problem is that this string is empty, maybe something is wrong in the way that i am getting the response. I have been trying to find out whats wrong for a long time. please help

Your webservice is returning a String.
Try using this to solve your problem
Object result = envelope.getResponse();
when your webservice return values of type byte[] ,you can do this:
SoapObject response=(SoapObject)envelope.bodyIn;
Hope it helps
