Is it possible to make arithmetic calculation automatically when checkbox is pressed? I want to add the total harga (total price) change based the choice of checkbox topping prices and add them with the basic prices (product price).
ex:
checked CB Extra Ayam and CB Kepala will add 3000 + 4000
then add it with basic product price 10000
so the total price would be 17000
and the total price will back to 10000 when im unchecked CB Extra Ayam and CB Kepala and so on
Here is my code
if (Code.toUpperCase().matches((inMieAyam.toUpperCase()))){
//set text topping
CBTopping1.setText("Extra Ayam");
CBTopping2.setText("Extra Tetelan Sapi");
CBTopping3.setText("Cakar (2 pcs)");
CBTopping4.setText("Kepala");
CBTopping5.setText("Bakso Sapi");
CBTopping6.setText("Telur Mata Sapi");
CBTopping7.setText("Balungan Rica Ayam");
CBTopping8.setText("Extra Sawi");
CBTopping9.setText("Extra Acar");
//hide remaining topping CB
CBTopping10.setVisibility(View.GONE);
//set price to variable
Price1 = 3000;
Price2 = 7000;
Price3 = 4000;
Price4 = 4000;
Price5 = 3000;
Price6 = 4000;
Price7 = 4000;
Price8 = 1000;
Price9 = 1000;
Price10 = 0;
//set price topping
TxtvToppingPrice1.setText("Rp."+Price1);
TxtvToppingPrice2.setText("Rp."+Price2);
TxtvToppingPrice3.setText("Rp."+Price3);
TxtvToppingPrice4.setText("Rp."+Price4);
TxtvToppingPrice5.setText("Rp."+Price5);
TxtvToppingPrice6.setText("Rp."+Price6);
TxtvToppingPrice7.setText("Rp."+Price7);
TxtvToppingPrice8.setText("Rp."+Price8);
TxtvToppingPrice9.setText("Rp."+Price9);
//hide remaining topping price Txtv
TxtvToppingPrice10.setVisibility(View.GONE);

}
edit :
turn out the variables is not changed in the checkbox listener
default FinalPrice1 is 0 when im changed it from checkbox listener it would not change to Price1 values, it still 0. I tried to change it directly by writing value to it FinalPrice1 = 10000 also no luck it just say 0.
if I remove the
FinalPrice1 = 0;
FinalPrice2 = 0;
FinalPrice3 = 0;
FinalPrice4 = 0;
FinalPrice5 = 0;
FinalPrice6 = 0;
FinalPrice7 = 0;
FinalPrice8 = 0;
FinalPrice9 = 0;
FinalPrice10 = 0;
it would be nullpointer error
i dont know whats wrong
i cant paste the whole code because the post didn't allow it, its too long lmao
the variable of the TotalFinalPrice just not changed or maybe not calculated
When your TextView have to be updated, use invalidate() method.
This must be called from a UI thread. To call from a non-UI thread, call postInvalidate().
For your case use TxtvTotalHarga.invalidate();.
I think you should first handle your objects into arrays, using tag value to save initial prices, create one event listener ( handle using object'd getTag() or array index....
And important: move the setOn..... out of the if. These call should be done onStart, before you trigger this event.
And can yoi also give more code on the context that this big if is calling?
Did you debug with AS to see these events triggered?

Hello I'm a student and My project is making a application by android studio.
I'm just a beginner so everything is difficult :(
Here is my problem.
I dynamically created checkbox depending on the current.
I want to get finalMemberTag if user click the btnEx button.
But In this code, When I click the btnEx, finalMemberTag is null.
And I want that If user click the checkbox, add the checkbox's text to the finalMemberTag.
and checkbox is unchecked, remove the checkbox's text to the finalMemberTag.
How can I do these?
(I already set the drawable things.)
Please Help me...

Ok, you have some issues with your code:
First, finalMemberTag is always null because you never initialized it. If you want to use a string array and you want to store the text on the checkboxes then we should assume that at most you'll have all of the checkboxes (16) selected. This means you'll want to initialize your array as:
private String[] finalMemberTag = new String[16]
Second, I think you'd be better off using a string set to avoid duplicates, or, if you need the information on a particular index, an arraylist.
With the Set:
private Set<String> finalMembersTag = new HashSet<>(16);
//onCreate...other stuff...for loop
//...setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
final String buttonText = buttonView.getText().toString();
if (isChecked) {
// other stuff ...
finalMembersTag.add(buttonText);
} else {
// other stuff ...
finalMembersTag.remove(buttonText);
}
}
With the ArrayList:
private List<String> finalMembersTag = new ArrayList<>(16);
//onCreate...other stuff...for loop
int index = i;
chA.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
final String buttonText = buttonView.getText().toString();
if (isChecked) {
// other stuff ...
finalMembersTag.add(buttonText); //this will add the text
} else {
// other stuff ...
finalMembersTag.remove(buttonText); //this will remove the element if found, or if you want an empty string you can do finalMembersTag.add(index, "");
}
}
i am facing an issue but it is not showed in LOGCAT as it is not a code error or null
the issue is that if the question has 2 answers and user selects both of them it counts in right answer but if the question has only 1 answer the game calculates it to wrong answer even if the user selected the right answer i will post a screenshot for that enter image description here
i have already coded that the correct answer would be bold and red as you can see

i think the error will be in this part of Question fragment in logic but can not get it (it is for if the correct answer has 2 values or 1 value)

} else if (Common.selected_values.size() == 1) {
Object[] arrayAnswer = Common.selected_values.toArray();
result.append((String) arrayAnswer[0]).substring(0, 1);
}
just found out the answer but i will not delete the post so if someone else got same issue
i simply removed the second part and edited the first part condition as follow
CurrentQuestion currentQuestion = new CurrentQuestion(questionIndex, Common.ANSWER_TYPE.NO_ANSWER);//DEFAULT IS NO ANSWER
StringBuilder result = new StringBuilder();
if (Common.selected_values.size() >= 1) {
Object[] arrayAnswer = Common.selected_values.toArray();

if (i < arrayAnswer.length - 1)

I have 4 checkboxes, when I check tick one, two or more. I want to populate my spinner with values, 1-5 if checkbox 1 is checked, 6-10 if checkbox 2 is checked, etc.. I have this logic here.
public void populateSpinnerToothNumber() {
if (cbQuadrant1.isChecked()) {
ArrayList<String> toothNumber = new ArrayList<>();
toothNumber.add("1");
toothNumber.add("2");
toothNumber.add("3");
toothNumber.add("4");
toothNumber.add("5");
ArrayAdapter<String> stringArrayAdapter = new ArrayAdapter<>(this, R.layout.support_simple_spinner_dropdown_item, toothNumber);
spinnerToothNumber.setAdapter(stringArrayAdapter);
} else if (cbQuadrant2.isChecked()) {
} else if (cbQuadrant3.isChecked()) {
} else if (cbQuadrant4.isChecked()) {
} else if (cbQuadrant1.isChecked() && cbQuadrant2.isChecked()) {
ArrayList<String> toothNumber = new ArrayList<>();
toothNumber.add("1");
toothNumber.add("2");
toothNumber.add("3");
toothNumber.add("4");
toothNumber.add("5");
toothNumber.add("6");
toothNumber.add("7");
toothNumber.add("8");
toothNumber.add("9");
toothNumber.add("10");
ArrayAdapter<String> stringArrayAdapter = new ArrayAdapter<>(this, R.layout.support_simple_spinner_dropdown_item, toothNumber);
spinnerToothNumber.setAdapter(stringArrayAdapter);
}
}
How can I improve the logic?
UPDATE
public void populateSpinnerToothNumber() {
final ArrayList<String> toothNumber = new ArrayList<>();
cbQuadrant1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
for (int x = 1; x <= 5; x++) {
toothNumber.add(String.valueOf(x));
}
}
});
cbQuadrant2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
for (int x = 6; x <= 10; x++) {
toothNumber.add(String.valueOf(x));
}
}
});
cbQuadrant3.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
for (int x = 11; x <= 15; x++) {
toothNumber.add(String.valueOf(x));
}
}
});
cbQuadrant4.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
for (int x = 16; x <= 20; x++) {
toothNumber.add(String.valueOf(x));
}
}
});
ArrayAdapter<String> stringArrayAdapter = new ArrayAdapter<String>(this, R.layout.support_simple_spinner_dropdown_item, toothNumber);
spinnerToothNumber.setAdapter(stringArrayAdapter);
}
This solved the problem :) Managed it with checkbox.setOnCheckedChangeListener Thanks for helping! :)
Adding to #Nilesh Rathod. You can have a method like called populateSpinner (int bgCount, int Endcount) which takes in the amount of tooth number needed from the beginning range to the end.
private void populateSpinner (int bgCount, int Endcount) {
ArrayList<String> toothNumber = new ArrayList<>();
for (int i = bgCount; i < Endcount; i++) {
toothNumber.add(i);
}
ArrayAdapter<String> stringArrayAdapter = new ArrayAdapter<>(this, R.layout.support_simple_spinner_dropdown_item, toothNumber);
spinnerToothNumber.setAdapter(stringArrayAdapter);
}
Call the method like this in your check boxes OnCheckedChangeListener.
populateSpinner (1, 5);
you should use OnCheckedChangeListener
Interface definition for a callback to be invoked when the checked state of a compound button changed.
sample code
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
ArrayList<String> toothNumber = new ArrayList<>();
toothNumber.add("1");
toothNumber.add("2");
toothNumber.add("3");
toothNumber.add("4");
toothNumber.add("5");
ArrayAdapter<String> stringArrayAdapter = new ArrayAdapter<>(this, R.layout.support_simple_spinner_dropdown_item, toothNumber);
spinnerToothNumber.setAdapter(stringArrayAdapter);
}
}
}
);
checkBox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
ArrayList<String> toothNumber = new ArrayList<>();
toothNumber.add("1");
toothNumber.add("2");
toothNumber.add("3");
toothNumber.add("4");
toothNumber.add("5");
toothNumber.add("6");
toothNumber.add("7");
toothNumber.add("8");
toothNumber.add("9");
toothNumber.add("10");
ArrayAdapter<String> stringArrayAdapter = new ArrayAdapter<>(this, R.layout.support_simple_spinner_dropdown_item, toothNumber);
spinnerToothNumber.setAdapter(stringArrayAdapter);
}
}
}
);
hey how can i know that the below checkbox when clicked is from which row of the list.
is there any way of knowing that. Every time yo is returning false which is its default value.
checkBox.setOnClickListener( new View.OnClickListener() {
public void onClick(View v) {
CheckBox cb = (CheckBox) v ;
callBlockOptions callBlockOptions = (callBlockOptions) cb.getTag();
callBlockOptions.setChecked( cb.isChecked() );
String yo;
if(callBlockOptions.getPosition()=="0")
{
callBlockOptions.setAllCalls();
}
if(callBlockOptions.getAllCalls() ==true)
yo="true";
else
yo="false";
Toast.makeText(getContext(), callBlockOptions.getPosition(), Toast.LENGTH_LONG).show();
}
});
}
After seeing your code, one thing you might want to try is setting listeners for the individual children within the ListView. You could do something like this:
ListView listView = (ListView)findViewById(R.id.listView);
int count = listView.getChildCount();
for (int x = 0; x < count; x++)
{
Class<? extends View> c = listView.getChildAt(x).getClass();
if (c == CheckBox.class)
{
CheckBox checkBox = (CheckBox)(listView.getChildAt(x));
checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener(){
#Override
public void onCheckedChanged(CompoundButton compoutButton, boolean isChecked) {
// TODO Auto-generated method stub
callBlockOptions.isChecked = isChecked;
}
});
}
else if (c == TextView.class)
{
TextView textView = (TextView)(listView.getChildAt(x));
textView.setOnEditorActionListener(new OnEditorActionListener(){
#Override
public boolean onEditorAction(TextView tView, int arg1, KeyEvent arg2) {
// TODO Auto-generated method stub
callBlockOptions.name = tView.getText().toString();
return true;
}
});
}
You probably want your other class to be like this:
public class callBlockOptions {
public static String name;
public static Boolean isChecked;
}
Then you can get and set name and isChecked like this:
callBlockOptions.isChecked = false;
Boolean boolVal = callBlockOptions.isChecked;
I have 80 EditText fields (cube[i]) and want to read what is in inside the text fields when the text field loses focus.
I can detect when any of the EditTexts (cube) loses focus but I cannot detect exactly which one, Im trying to find which cube is focused on.
the line "EditText cube = (EditText) v.getClass();" is giving me an error
Maybe I can use the View v?
for (int i = 0; i < cube.length; i++) {
cube[i].setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
EditText cube = (EditText) v.getClass();
String s = cube.getText().toString();
//cubecolor();
}
}
});
}
}
Any help is appreciated.
while creating set some tag to the editText like this (pseudo code)
EditText edit = new EditText(context);
edit.setTag(Integer.valueOf(i)); // i is within the for loop;
Now during the onFocus get the tag
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
EditText cube = (EditText) v;
Integer tag = (Integer)cube.getTag();
//code to sort out which cube based on tag
String s = cube.getText().toString();
//cubecolor();
}
}
This worked, Thanks Dante.
for (int i = 0; i < cube.length; i++) {
cube[i].setTag(Integer.valueOf(i)); // give cubes tags
}
for (int i = 0; i < cube.length; i++) {
cube[i].setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
Integer tag = (Integer) v.getTag();
String s = cube[tag].getText().toString();
Log(TAG, " Content" + s);
revert_cubecolor(tag);
}
}
});
}
