How to add onClick for buttons?

How to add onClick for buttons? - android

I'm trying to figure out why my app crashes when my AddThreeToTeamA button crashes my application upon clicking. I have addded my XML and my Java code.
I am following a tutorial however it obviously does not crash and I have tried several different solutions.
Any hint will be appreciated.

int scoreTeamA;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void addThreeForTeamA() {
scoreTeamA = score + 3;
displayForTeamA(scoreTeamA);
}
public void addTwoForTeamA() {
scoreTeamA = score + 2;
displayForTeamA(scoreTeamA);
}
public void addOneForTeamA() {
scoreTeamA = score + 1;
displayForTeamA(scoreTeamA);
}
public void displayForTeamA(int score) {
TextView scoreView = (TextView) findViewById(R.id.Team_A_Score);
scoreView.setText(String.valueOf(scoreTeamA));
}

All methods defined using the android:onClick="someMethod" attribute. Then they have to be public and should pass a View as the only parameter, Change your methods to:
public void someMethod(View view){
//Everything else!
}
Your methods do not pass a View as the only parameter at all currently!

Android Initial Login Screen then use fragments to swipe between screens once login is successful

I am trying to create an Android app, then has an initial login screen that detects if a user is Admin or User. Once logged in, the user (depending on their role) will see different tabs to swipe between. I have a basic app that starts with a login activity and the login to decipher the users roles (using static values for now). First part is ok. Now when I try to use Fragments after the login screen, I'm getting stuck.
I have a LoginActivity that has an onClikcListener on a button after user enters credentials. Depending on whether the user is Amin or General Users, it will just to a new activity either activity_vote_admin or activity_vote_user. At this point I am stuck. Any ideas if what I am trying to do is valid. Or is there a better way to do this. At the moment I am getting this error.

My fragments are as follows.

#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.activity_vote_user, container, false);
}
}
...

There are two reason for this issue :
You didn't declare any button on "activity_vote_main_admin.xml", thats why your view not binding with activity and giving null pointer exception.
May be you declare the button on fragment xml and trying to bind it with activity.

I'm having trouble with phone number authentication. Verify_otp generates a unique code for any verified number

I'm having trouble with phone number authentication. Verify_otp generates a unique code for any verified number. But the biggest problem is that it only generates the code if the numbers start with 6599 ..... a number 6598 .... it no longer generates the code.
I can not find an outlet for him to accept any phone number.
this is a part of the RegistrationModel.java file
public static class OTP_Details{
/**
* status : 2
* message : Otp Sent to phone for Verification
* otp : 2017
* auto_otp : 1
*/
private int status;
private String message;
private String otp;
private int auto_otp;
public int getStatus() {
return status;
}
public void setStatus(int status) {
this.status = status;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getOtp() {
return otp;
}
public void setOtp(String otp) {
this.otp = otp;
}
public int getAuto_otp() {
return auto_otp;
}
public void setAuto_otp(int auto_otp) {
this.auto_otp = auto_otp;
}
}
}

Ready! I've submitted below the files I've listed. After typing the phone and clicking send otp, the code that comes back is always the code 2017, that is the first code I sent, but it only sends this code 2017 if the numbers start like this: 6599 .... if the number is so for example: 6598 .... it does not generate the code 2017 and can not continue the registration.

onFocusChange Doesnt respond from within a view pager

Reposting this as I initially posted it originally with the wrong title and so it got lost in the void of questions.
I'm creating a small timetable app, and am currently creating a screen with some tabs. Each tab is a seperate fragment and each have 20 edit texts inside of them. What I aim to do, is if the user types in one of the edit texts, then clicks off of it and the focus is lost, to send the text from the edit text field to the main activity. Then, when the confirm button is clicked, any text that is in the edit texts is then saved to an SQLite database.
My problem is that the focus listener doesn't seem to be working.
Here is one of the fragment's code:
package com.example.schoolandrevisiontimetable;
import android.support.v4.app.Fragment;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnFocusChangeListener;
import android.view.ViewGroup;
import android.widget.EditText;
public class Input_slessontime_monday extends Fragment implements OnFocusChangeListener{
OnMondayEditTextChangedListener monCallback;
private String mondayString;
private int mondayPeriod;
private int mondayPosition;
public void MondayEditTextChanged(String mondayEditText, int period, int position){
mondayString = mondayEditText;
mondayPeriod = period;
mondayPosition=position;
monCallback.onMondayEditTextChanged(mondayString, mondayPeriod, mondayPosition);
}
public interface OnMondayEditTextChangedListener {
public void onMondayEditTextChanged(String mondayEditText, int period, int position);
}
EditText[][] mondayInput = new EditText[11][2];
String [][] mondayStrings = new String [11][2];
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_input_slessontime_monday,
container, false);
mondayInput[1][0] = (EditText) rootView.findViewById(R.id.mondayslesson1start);
mondayInput[1][1] = (EditText) rootView.findViewById(R.id.mondayslesson1end);
mondayInput[2][0] = (EditText) rootView.findViewById(R.id.mondayslesson2start);
mondayInput[2][1] = (EditText) rootView.findViewById(R.id.mondayslesson2end);
...
//this continues up to 10. Had to delete the rest due to character limitations
Log.v("Monday", "Edit texts all set");
return rootView;
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
// This makes sure that the container activity has implemented
// the callback interface. If not, it throws an exception
try {
monCallback = (OnMondayEditTextChangedListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnMondayEditTextChanged");
}
}
#Override
public void onFocusChange(View v, boolean hasFocus) {
Log.v("monday", "focus change!");
String edittext;
if(!hasFocus)
switch(v.getId()){
case R.id.mondayslesson1start:
edittext = mondayInput[1][0].getText().toString();
MondayEditTextChanged(edittext,1,0);
break;
case R.id.mondayslesson1end:
edittext = mondayInput[1][1].getText().toString();
MondayEditTextChanged(edittext,1,1);
break;
case R.id.mondayslesson2start:
edittext = mondayInput[2][0].getText().toString();
MondayEditTextChanged(edittext,2,0);
break;
case R.id.mondayslesson2end:
edittext = mondayInput[2][1].getText().toString();
MondayEditTextChanged(edittext,2,1);
break;
//this continues up to 10. Had to delete the rest due to character limitations
}
}
}

Something that may be related, is that when I click on or off an edit text, or scroll the fragment, getCount() is called. Probably unrelated.
Thanks in advance!

needed to set an onFocusListener.

Please help....

mainactivity.java
package com.example.internationalization12;
import android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//getActionBar().hide();
}
}

Try this :
package com.example.internationalization12;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
public class MainActivity extends Activity {
TextView txtSignUp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtSignUp=(TextView)findViewById(R.id.txt_sign_up);
txtSignUp.setText(Html.fromHtml("<u>Dont have account?SignUp</u>")
txtSignUp.setOnClickListener(signUpListener);
//getActionBar().hide();
}
public OnClickListener signUpListener=new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
startActivity(new Intent(MainActivity.this,Welcome.class));
}
};
}

You have to setOnTouchListener to the TextView. Here I give you an example:
public class MainActivity extends Activity implements View.OnTouchListener {
private TextView tv1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv1 = (TextView) findViewById(R.id.tv1);
tv1.setOnTouchListener(this);
}
#Override
public boolean onTouch(View v, MotionEvent event) {
// HERE YOU HAVE TO CHECK WHICH ID IS SELECTED, IF YOU HAVE MORE THAN ONE,
// AND WHICH EVENT HAS THE USER DONE.
// IN YOUR CASE.. OPEN WEBSITE LIKE THIS:
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);
return true;
}
}

you can try Linkify here
textview.setText("www.androiddeveloper.com");
Linkify.addLinks(textview, Linkify.WEB_URLS);

multiply with zero, double no number

I am trying to build a calculator for android, i am trying to multiply two numbers.
If i give number 1 and leave number 2 open, i want to get zero as an answer.
I first thought it could be the problem of not having a value for the double.
So i tried: if (Double.isNaN(number1)) { number1=0; }
But it did not work.
How do i make this happen?

multiply=(number1calc*number2calc);
multiplydisplay.setText(Double.toString(multiply));
}
private void reset() {
multiplydisplay.setText("");
number1.setText("");
number2.setText("");
}
}

you should just check that the content of the textfield of the value is different than "". If not, just assign the value 0.
In calculate :
private void calculate() {
number1calc=(number1.getText().toString() != "" ) ? Double.parseDouble(number1.getText().toString()) : 0;
number2calc=(number2.getText().toString() != "" ) ? Double.parseDouble(number2.getText().toString()) : 0;
multiply=(number1calc*number2calc);
multiplydisplay.setText(Double.toString(multiply));
}

if(numberOne.getText().toString().trim().length() < 1 || numberTwo.getText().toString().length() < 1){
multiplyDisplay.setText("0");
}
else{
//default handling
}
If the edittext is left blank, this is obviously not a number(NaN). Doing any operation with NaN in Java will cause the result of this operation to be NaN.

How to add onClick for buttons? - android

All methods defined using the android:onClick="someMethod" attribute. Then they have to be public and should pass a View as the only parameter, Change your methods to: public void someMethod(View view){ //Everything else! } Your methods do not pass a View as the only parameter at all currently!
