Of course there is a simpler way. Just make your Activity where you are doing this implement OnCheckedChangeListener
public Class MyActivity extends Activity implements OnCheckedChangeListener{
//your activity logic in here
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
//your Activity will now receive onCheckedChangeEvents here from
//the checkboxes to which you assign it as a listener
}
}
, in onCreate, after you get references to all of your day checkboxes, set the Activity as the listener like this
@Override
public void onCreate(Bundle savedInstanceState){
//first get references to all your checkboxes and assign them to mon, tue, wed etc.
//then set the listeners
mon.setOnCheckedChangeListener(this);
tue.setOnCheckedChangeListener(this);
wed.setOnCheckedChangeListener(this);
thu.setOnCheckedChangeListener(this);
fri.setOnCheckedChangeListener(this);
sat.setOnCheckedChangeListener(this);
sun.setOnCheckedChangeListener(this);
}
, make sure all of your checkboxes have IDs assigned to them in the layout xml, like this
<CheckBox
android:id="@+id/checkMonday"
....
, then you will have one onCheckedChange method where you can handle the different days like this
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
int id = buttonView.getId();
if(isChecked){
counter++; //a day has been checked
}else{
counter--; //a day has been unchecked
}
switch(id){
case R.id.checkMonday:
//logic for Monday
break;
case R.id.checkTuesday:
//logic for Tuesday
break;
...
}
}
That should do the trick!
