Improve this question
I have been developing a form which uses Radio buttons and has a list of questions.
When the user clicks on Yes radio button for every question, I want to increment the score by 20. If the user clicks the No radio button, the score should be 0.
Take a look at the code.
This is the Activity class
CoughTest.java
public class CoughTest extends AppCompatActivity {
int score= 0;
RadioGroup rg1,rg2,rg3,rg4,rg5;
RadioButton rb;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cough_test);
rg1 = (RadioGroup) findViewById(R.id.rgroup1);
rg2 = (RadioGroup) findViewById(R.id.rgroup2);
rg3 = (RadioGroup) findViewById(R.id.rgroup3);
rg4 = (RadioGroup) findViewById(R.id.rgroup4);
rg5 = (RadioGroup) findViewById(R.id.rgroup5);
}
public void rbClicked(View view) {
int radioButtonId = rg1.getCheckedRadioButtonId();
rb =(RadioButton) findViewById(radioButtonId);
boolean checked = ((RadioButton) view).isChecked();
switch (view.getId()){
case R.id.yes1:
score = score + 20;
break;
case R.id.no1:
score = 0;
break;
case R.id.yes2:
score = score + 20;
break;
case R.id.no2:
score = 0;
break;
case R.id.yes3:
score = score + 20;
break;
case R.id.no3:
score = 0;
break;
case R.id.yes4:
score = score + 20;
break;
case R.id.no4:
score = 0;
break;
case R.id.yes5:
score = score + 20;
break;
case R.id.no5:
score = 0;
break;
}
}
}

I will suggest this method:
CoughTest.java:
public class CoughTest extends AppCompatActivity {
private Button btnSubmit, btnReset;
private TextView finalScore;
private RadioButton cough, sourThroat, fever, tiredness, breathing;
private int score = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cough_test);
btnSubmit = (Button) findViewById(R.id.btnSubmit);
btnReset = (Button) findViewById(R.id.btnReset);
finalScore = (TextView) findViewById(R.id.textFinalScore);
cough = (RadioButton) findViewById(R.id.cough);
sourThroat = (RadioButton) findViewById(R.id.sour_throat);
fever = (RadioButton) findViewById(R.id.fever);
tiredness = (RadioButton) findViewById(R.id.tiredness);
breathing = (RadioButton) findViewById(R.id.breathingDifficulty);
btnSubmit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (cough.isChecked()) {
score = score + 20;
} else {
score = score + 0;
}
if (sourThroat.isChecked()) {
score = score + 20;
} else {
score = score + 0;
}
if (fever.isChecked()) {
score = score + 20;
} else {
score = score + 0;
}
if (tiredness.isChecked()) {
score = score + 20;
} else {
score = score + 0;
}
if (breathing.isChecked()) {
score = score + 20;
} else {
score = score + 0;
}
//Finally show your score.
Toast.makeText(getApplicationContext(), "Score is: " + score, Toast.LENGTH_SHORT).show();
}
});
//Resetting everything
btnReset.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
score = 0;
cough.setChecked(false);
fever.setChecked(false);
breathing.setChecked(false);
tiredness.setChecked(false);
sourThroat.setChecked(false);
}
});
}
}

I have removed the radio groups. Just prompt your user to click it when they agree.
Means if their answer is YES, then please check the radio button else leave it unchecked.
Hope that helps.
By the way this is how it works:

just set score into your textView after your switch case :
yourTextView = String.ValueOf(score);

EditText's not changing on ImageButton press?

I am very new to coding so there could be all sorts of issues with this but after doing a fair bit of searching, I can't find whats wrong with it, I don't get any errors or crashes, the buttons just do nothing?
The aim is to have the orange arrows increase and decrease the number in the middle by 1.

My main java (named CameraActivity):

}
if (requestCode == EDIT_REQUEST) {
Bundle b = getIntent().getExtras();

startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
}class push_buttonClicker implements Button.OnClickListener{
public void onClick(View v){
Intent Intent = new Intent(CameraActivity.this, SecondActivity2.class);
CameraActivity.this.startActivityForResult(Intent, EDIT_REQUEST);
}}}
AND my secondActivity.java:
public class SecondActivity2 extends AppCompatActivity {
TextView tvView;
EditText EditName;
EditText EditID;
Button buttonCancel;
Button buttonSave;
CheckBox checkBox;
TextView Name;
TextView ID;
private static final int RESULT_OK = 10;
//private static final int RESULT_CANCELED = 2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second2);
// CheckBox Yes = (CheckBox) findViewById(R.id.Yes);
// CheckBox NO = (CheckBox) findViewById(R.id.NO);
buttonSave = (Button) this.findViewById(R.id.buttonSave);
buttonCancel = (Button) findViewById(R.id.buttonCancel);
EditName = (EditText) findViewById(R.id.EditName);
EditID = (EditText) findViewById(R.id.EditID);
buttonSave.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
Intent data = new Intent();
data.putExtra("name", EditName.getText().toString());
data.putExtra("ID", EditID.getText().toString());
setResult(RESULT_OK, data);
finish();
}
});}}

change your code inside onActivityResult under EDIT_REQUEST condition
String name = data.getStringExtra("name");
String ID = data.getStringExtra("ID");
Name.setText(name);
ID.setText(ID);
no need to create a Bundle there, it will solve your problem.

Now when I run my app I get a NullPointerException within the onCreateView() within the onClick at the line:
String newName = name.getText().toString().trim();
Now I have tried printing out the variables, debugging but I just cannot seem to figure out why it is getting a NullPointerException. It may be something simple that I'm overlooking, I've just been looking at it for so long I may just be going crazy.

I think your EditText 'name' is not initialized.

You have not initialized those EditText, so you are getting NPE. initialize those components first ..From your code call this method setupTextFieldsByContact() in onCreate it will solve your problem.

Of course you're getting a NullPointerException...you never initialized your EditTexts in the onCreate method. Add this to your onCreate:
name = (EditText) findViewById(R.id.editContactName);
description = (EditText) findViewById(R.id.editContactDescription);
primaryNumber = (EditText) findViewById(R.id.editContactPrimaryNumber);
secondaryNumber = (EditText) findViewById(R.id.editContactSecondaryNumber);
email = (EditText) findViewById(R.id.editContactEmail);
skype = (EditText) findViewById(R.id.editContactSkype);
That way you'll be calling methods on objects that actually exist.

your EditText 'name' is not initialized. you have to initialized your EditText first

The white spaces between your textviews are textviews that arent hidden, try to hide them when you have no data for them like:
if(nsPutih==true) {
tvOutput1.setText("Nasi Putih");
tvOutput1.setVisibility(View.VISIBLE);
} else {
tvOutput1.setVisibility(View.GONE);
}
However this is bad practice, you should try to dynamically create the textviews by putting them in a ListView. Also try to pass the data to the activity using a Map of objects.

with your intent try to pass your values with putextra and getextra method it will work
