Passing database value to variable

I'm rarely ask on here, so first of all I'm sorry if my question is readable or not allowed here. So what I'm trying to do here is passing the username from LoginActivity into the player1 variable at HomeActivity . here's the code for the HomeActivity.java class
public class HomeActivity extends Activity {
TextView NameTxt;
TextView CoinTxt;
TextView GemTxt;
String p1name = player1.getName();
int p1coin = player1.getCoins();
int p1gem = player1.getGems();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_screen);
//////TV declare///////
NameTxt = (TextView)findViewById(R.id.playerName);
CoinTxt = (TextView)findViewById(R.id.cointxt);
GemTxt = (TextView)findViewById(R.id.gemtxt);
NameTxt.setText(p1name);
CoinTxt.setText("Coin: " +p1coin);
GemTxt.setText("Gem: " +p1gem);
}
}
And this is LoginActivity.class
public class LoginActivity extends Activity {
EditText edit1;
EditText edit2;
EditText edit3;
Button registerBtn;
Button loginBtn;
DatabaseHelper myDb;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Set fullscreen and no title//////////
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
///////////////////////////////////////
setContentView(R.layout.login_screen);
edit1 = (EditText)findViewById(R.id.editpname);
edit2 = (EditText)findViewById(R.id.editpemail);
edit3 = (EditText)findViewById(R.id.editppw);
registerBtn = (Button)findViewById(R.id.registerbtn);
loginBtn = (Button)findViewById(R.id.loginbtn);
myDb = new DatabaseHelper(this);
loginBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (validate()) {
String Email = edit2.getText().toString();
String Password = edit3.getText().toString();
User currentUser = myDb.Authenticate(new User(null, null, Email, Password));
if (currentUser != null) {
System.out.println("Successfull");
Intent intent = new Intent(getApplicationContext(),HomeActivity.class);
startActivity(intent);
finish();
} else {
System.out.println("Unsuccessfull");
}
}
}
});
registerBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (validate()) {
String UserName = edit1.getText().toString();
String Email = edit2.getText().toString();
String Password = edit3.getText().toString();
if (!myDb.isEmailExists(Email)) {
myDb.addUser(player1);
public User player1 = new User(null, UserName, Email, Password);
}
}
}
});
}
public boolean validate() {
boolean valid = false;
String Email = edit2.getText().toString();
String Password = edit3.getText().toString();
if (!android.util.Patterns.EMAIL_ADDRESS.matcher(Email).matches()) {
valid = false;
edit2.setError("Please enter valid email!");
} else {
valid = true;
edit2.setError(null);
}
if (Password.isEmpty()) {
valid = false;
edit3.setError("Please enter valid password!");
} else {
if (Password.length() > 5) {
valid = true;
edit3.setError(null);
} else {
valid = false;
edit3.setError("Password is to short!");
}
}
return valid;
}
}
And I also have simple User.java class
String id;
String userName;
String email;
String password;
int coins;
int gems;
public User(String id, String userName, String email, String password) {
this.id = id;
this.email = email;
//And so on. Don't mind this
}
public String getName() {
return this.userName;
}
public int getCoins() {
return this.coins;
}
public int getGems() {
return this.gems;
}
And I write the short code , for the sake of readability.
I get an error on
myDb.addUser(player1);
And the one below it.
I'm just trying to make so that the player name equals to the value of Username on the database . and also the coins and gems too. Can you guys help me to get the idea how to pass the value? It tooks me whole 3days to figure a way to fix this. And it just blew my brain. So maybe you guys can help me

Ignoring the database stuff and assuming that LoginActivity is started from another activity (MainActivity) then you could adapt the following which passes the Username and UserId (ample to then get any additional data in the HomeActivity from the database).
So this when it starts immediately invokes the LoginActivity.
Clicking Login (mimics getting user and id from db) starts the HomeActivity passing the Username and userid via Intent Extras.
The HomeActivity displays the username and userid, and additionally a DONE button.
Clicking the DONE button returns back through the stack (skippng LoginActivity as that was finished) to the MainActivity which changes the TextView from Hello World to Welcome Back (not that you'd ever see Hello World).
MainActivity.java :-
public class MainActivity extends AppCompatActivity {
TextView mMessage;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMessage = this.findViewById(R.id.message);
// Immediately start Login Activity
Intent i = new Intent(MainActivity.this,LoginActivity.class);
startActivity(i);
}
#Override
protected void onResume() {
super.onResume();
mMessage.setText("Welcome back");
}
}
LoginActivity.java :-
public class LoginActivity extends AppCompatActivity {
public static final String INTENTKEY_USERNAME = "IK_USERNAME";
public static final String INTENTKEY_USERID = "IK_USERID";
Button mloginbtn;
Context mContext;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
mContext = this;
mloginbtn = this.findViewById(R.id.loginbtn);
mloginbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent i = new Intent(mContext,HomeActivity.class);
i.putExtra(INTENTKEY_USERNAME,"Fred");
i.putExtra(INTENTKEY_USERID,99L);
startActivity(i);
finish();
}
});
}
}
HomeActivity.java
public class HomeActivity extends AppCompatActivity {
TextView mUsername, muserid;
Button mDone;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
mUsername = this.findViewById(R.id.username);
muserid = this.findViewById(R.id.userid);
mDone = this.findViewById(R.id.done);
mDone.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
finish();
}
});
Intent i = this.getIntent();
mUsername.setText(i.getStringExtra(LoginActivity.INTENTKEY_USERNAME));
muserid.setText(String.valueOf(i.getLongExtra(LoginActivity.INTENTKEY_USERID,0)));
}
}

I'd do the following:
...
Intent intent = new Intent(getApplicationContext(),HomeActivity.class);
intent.putExtra("username", Bob)
startActivity(intent);
finish();
...
and then in home have:
Intent intent = getIntent();
String easyPuzzle = intent.getExtras().getString("username");

Whenever I click the button it gives me last value result not current

Whenever I execute data function it stores the correct value of QUERY but when i get the JSON back. It gives me the result of last value rather than giving me the result of new value. Something is wrong in function data or function async.
There is no error which that I give you my error log.The QUERY string holds the right value but result is of last string.
public class MainActivity extends AppCompatActivity{
public static String QUERY = null;

Problem is you are calling a AsyncTask and right after it access same Variable which is modifying inside AsynCtask.
Async async = new Async ();
async.execute ();
if(DATA!=null){
textView1.setText (DATA);
}
Here async will execute on background thread but Main thread continues So last DATA value will set each time .
Solution
You better move setText() code to onPostExecute().onPostExecute()
runs on Main Thread so you can easily access Ui element inside it .
#Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute (aVoid);
MainActivity.DATA = data;
if(DATA!=null){
textView1.setText (DATA);
}
}

You are setting the text before async finishes to execute. You are calling
async.execute ();
if(DATA!=null){ textView1.setText (DATA);
async.execute returns right away, so DATA still has the old value.
What you have to do is set the textView text in onPostExecute function.

How to add asyncTask code in application?

I have a register activity in my application. This has inputs of userid,email,password and mobile no. I have created an UI.
code:
public class RegisterActivity extends AppCompatActivity {
TextView already;
Button signUp;
RelativeLayout parent;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
parent = (RelativeLayout)findViewById(R.id.parentPanel);
setupUI(parent);
already = (TextView)findViewById(R.id.alreadyRegistered);
signUp = (Button) findViewById(R.id.sign_up_button);
already.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(RegisterActivity.this,LoginActivity.class));
}
});
signUp.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(RegisterActivity.this,LoginActivity.class));
}
});
}
public static void hideSoftKeyboard(Activity activity) {
InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}
public void setupUI(View view) {
//Set up touch listener for non-text box views to hide keyboard.
if(!(view instanceof EditText)) {
view.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
hideSoftKeyboard(RegisterActivity.this);
return false;
}
});
}
//If a layout container, iterate over children and seed recursion.
if (view instanceof ViewGroup) {
for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
View innerView = ((ViewGroup) view).getChildAt(i);
setupUI(innerView);
}
}
}
}
Now I want to sync this UI with server.
For this I have a code of asyncTask created in another activity. How can I call this code or implement this code with UI?

In this dialog want to show events from asyncTask. Thank you.

Not sure if i understand your question correctly, but to execute the AsyncTask, you just have to create an instance of RegisterAsyncTask and call the execute() method on it.
RegisterAsyncTask task = new RegisterAsyncTask();
task.execute(yourMap);
// you can pass multiple params to the execute() method
Or, if you don't need to get ahold of the instance:
new RegisterAsyncTask().execute(yourMap);

You can simply put your hashmap object, alongwith AsyncTask in your login activity code, and simply call AsyncTask in following manner.
HashMap<String, String> params = new HashMap<String, String>();
params.put("userUsername", "user1");
params.put("userPassword", "user1");
params.put("gender", "M");
params.put("birthDate", "1986/7/12");
params.put("religion", "Hindu");
params.put("nationality", "Indian");
params.put("motherTongue", "Marathi");
params.put("birthPlace", "Pune");
params.put("userCountry", "India");
params.put("userState", "Maharashtra");
params.put("userCity", "Nashik");
params.put("userPincode", "422101");
params.put("userEmailid", "user1#gmail.com");
params.put("userMobileNo", "9696323252");
params.put("userPhoto", userPhoto);
//call asynctask like this.
RegisterAsyncTask task = new RegisterAsyncTask();
task.execute(params);

You can write and apply below mentioned steps (Please ignore any syntactical error, I am giving you simple logical steps).
step 1 - Make a global application level loginObject setter and getter like below. Make sure to define Application class in your manifest just like you do it for your LoginActivity
public class ApplicationClass extends Application{
private LoginBean loginObject;
public void setLoginBean(LoginBean object) {
this.loginObject = object;
}
public LoginBean getName() {
return this.loginObject
}
}
Step - 2 Get an instance of ApplicationClass object reference in LoginActivity to set this global loginObject
e.g. setLogin object in your current Loginactivity like this
......
private ApplicationClass appObject;
......
#Override
protected void onCreate(Bundle savedInstanceState) {
......
appObject = (ApplicationClass) LoginActivity.this.getApplication();
.......
appObject.setLoginBean(loginObject)
}
Step - 3 Get an instance of ApplicationClass object reference in any other Activity get this global loginObject where you need to access this login data.
e.g. getLogin object in your otherActivity like this
......
private ApplicationClass appObject;
......
#Override
protected void onCreate(Bundle savedInstanceState) {
......
appObject = (ApplicationClass) LoginActivity.this.getApplication();
.......
LoginBean loginObject = appObject.getLoginBean();
}

problem setting progress bar before alert dialog which has a spinner

public class classified extends Activity

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Agency");
builder.setAdapter(aaagency, new DialogInterface.OnClickListener()

Toast(strerrmess);
intflag=1;
}
else
{intflag=0;}
}
}
}
I am unable to get the value of strdata which i have initialized in asynctask function in the srcagency function. What should I do? Even though strdata is a global variable.
I have also tried this but I think you can't initialize array adapter in onpostexecute function...
#Override
protected void onPostExecute(Void unused)
{
dialog.dismiss();
if (strerrmess.equals("Please Enter atleast 3 Characters for Agency Searching"))
{Toast(strerrmess);intflag=1;}
else if(strerrmess.equals("Please Enter Characters for Agency Searching"))
{Toast(strerrmess);intflag=1;}
else if(strerrmess.equals("Your Session Got Expired. Please login again."))
{
Intent intent = new Intent(classified.this, loginscreen.class);
startActivity(intent);
Toast(strerrmess);
intflag=1;
}
else
{strarr= fun1.split(strdata, "^");
aaagency = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item , strarr);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Agency");
builder.setAdapter(aaagency, new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int item)
{
txtAgency.setText(strarr[item]);
}
});
builder.show();}
}
Any help or comments would be appreciated.
Thanks

Log.i("Classified Ad","srcAgency");
new srcAgency().execute();
srcAgency srcagen = new srcAgency();
strdata = srcagen.strtempdata;
This does not work. You are saying, start an AsyncTask that will set your strdata at some point in the future but also immediately return and after creating a new AsyncTask have it know what the last AsyncTask did.
Try this:
void srcAgency(View v){
//We only want to start the AsyncTask here, nothing else.
// Whatever you did before and whatever triggered the srcAgency(View) method
srcAgency srcagen = new srcAgency();
srcagen.execute();
return;
}
public void realSrcAgency(View v) {
... // The rest of original srcAgency(View)
}
// Inside of asyncTask srcAgency ...
public void postExecute() {
// Call the new method we just had, but after our asyncTask is done.
realSrcAgency(null);
}
Basically you can't expect all these things to happen simultaneously. It would be easy to help you if you trimmed down the specifics of your code. It looks like you just want a button or some click to start an async task that fills a strings. However after that string is filled do something else with it. Also I don't believe you need an async task for any of this.
