Dynamically setting CheckBox and get if all checkbox is checked

ArrayList<String> toDoArray = XYZ.getChecklistItems(reasonToCal);
for (int i = 0; i < toDoArray.size(); i++) {
final CheckBox checkbox = new CheckBox(this);
checkbox.setText(toDoArray.get(i));
checkbox.setTextColor(Color.parseColor("#FFFFFF"));
checkLinearLayout.addView(checkbox);
}
I am dynamically setting checkbox in my layout.
The problem I am facing is i cannot get if all my checkbox is checked so that i can enable the button if all checkboxes are checked

I guess you can implement common listener for all check-boxes which will increase variable of checked check-boxes and also decrease is user will uncheck any you should also keep somewhere total numbers of check-boxes and compare those two variables - if equals set enabled on button.
That can be one approach.

Android checkbox array

I have 12 CheckBox in an array and I have to check if more than 1 CheckBox is checked I have to get toast message "cannot select more than 1 checkbox".
My code:
chkArray = new CheckBox[12];
chkArray[0]=(CheckBox) findViewById(R.id.checkBox1);
chkArray[1]=(CheckBox) findViewById(R.id.checkBox2);
chkArray[2]=(CheckBox) findViewById(R.id.checkBox3);
chkArray[3]=(CheckBox) findViewById(R.id.checkBox4);
chkArray[4]=(CheckBox) findViewById(R.id.checkBox5);
and so on
chkArray[0].setOnClickListener(mListener);
chkArray[1].setOnClickListener(mListener);
chkArray[2].setOnClickListener(mListener);

A simple solution is adding a loop in the onCheckedChanged listener where you check each checkbox for true or false. If more than one checkbox is checked (including the last checked checkbox), set that checkbox to false and display the message.

try this
http://developer.android.com/reference/android/util/SparseBooleanArray.html
Store array of boolean value with index as a key.
put this on click listener of checkbox
if (mSparseBooleanArray.get(i)) {
//here value with true state
//here you can know any one item is selected
Toast.makeText(getContext(),"cannot select more than 1 checkbox",
Toast.LENGTH_LONG).show();
return;
}

I'm not sure what you are trying to accomplish, but it sounds like you want the functionality of radiobuttons instead of checkboxes.
RadioButton:
Radio buttons allow the user to select one option from a set. You should use radio buttons for optional sets that are mutually exclusive.

How to check if none of checkboxes is selected in android?

I am working on android project. I have 3 pages in which each page contains some decription and below the desciption 5 to 8 checkboxes. I kept the next button at the top of each page. I am storing the selected check box id's in an arraylist. i.e if I check the checkbox the id will be stored in the arraylist and if I uncheck the checkbox the id will be deleted from the arraylist. (I need the selected checkboxes fo further pages and hence this task). If none of the checkbox is selected and next button is clicked i want to display an alert saying that "Please select atleast one". How to check if none of the checkbox is selected and how to display an alert box? Please help me with this issue.
Thanks in advance

Loop through your ArrayList of IDs and check if each box is checked.
boolean isChecked = false;
for (int id : yourArrayOfIds) {
if (((CheckBox) findViewById(id)).isChecked()) {
isChecked = true;
break;
}
}
// If isChecked==true, a box is checked.
You may also want to check if the CheckBox object is null before using isChecked(). This is just a rudimentary example.
To show your alert, use something like this. There are lots of other tutorials and documentation as well.

How to check the checkbox after receiving the message in android

I am making an application for android mobiles in which i have to receive the message string and then split that string in parts(each parts containing 2 characters).I am able to do up-to this much.
And after this now i have to check the checkbox depending on the string.
For ex-if my String is a1a2a3
then i have splited into a1, a2 & a3.Now i have a screen of 5 vertical check boxes.where 1st box represent a1,2nd one a2 and so on the 5th one representing a5.
Now after receieving the message(a1a2a3) i want that when i open the checkbox page then i should get the first three checkboxes to be checked.
On testing with debugger attached i found that i am able to receive the message and also i am able to split the message string but i am not able to apply check on the checkboxes.
Plz help me out.its very urgent.
Thanks in advance:)

Do this:
CheckBox checkBox;
if(A.a1==1){
checkBox = findViewById(R.id.Checkbox_a1);
checkBox.setChecked(true);
}
Whats the rocket science in this? Have u added the tag:
setContentView(R.layout.main);

Checkbox's Text click Events

I am using checkbox for the purpose of checking "Term & Condications".
if user had selected only checkbox (Square icon) that means terms are accepted
and if not then terms are not accepted, but if user clicks on that checkbox's text then i should be able to view "terms & condications" page.
Thanks.

take one checkbox and on Textview(better to use button )
setOnClickListener on textView to show T&C .
check ckeckBox status throgh checkbox.ischecked() and work accordingly.

I don't know exactly what you want but you can do it with the checkbox. You need to create your checkbox and then you can check if checkbox is checked or not.
For example:
final CheckBox checkBox = (CheckBox) findViewById(R.id.checkbox_id);
if (checkBox.isChecked()) {
Toast.makeText(getApplicationContext(), "You accepted the Terms", Toast.LENGTH_SHORT);
}
else {
Toast.makeText(getApplicationContext(), "You haven't accepted the Terms", Toast.LENGTH_SHORT);
}
Here is one example, which can help to understand it:

Hope it helps.
