This is my code:
<CheckBox
android:id="@+id/sprint_checkbox"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/sprint_game" />
<CheckBox
android:id="@+id/marathon_checkbox"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/marathon" />
<CheckBox
android:id="@+id/never_ending_checkbox"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/never_ending" />
What i want to do is "detect" when one of these is checked and then set the other two to "disable", so the user can select only one at time. I tried to use the ".setOnCheckedChangeListener", but i can't do that, can someone help me with some code? Thanks a lot guys!
This is the way you are notified about checked changes:
CheckBox check = findViewById(R.id.sprint_checkbox);
check.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
//do stuff
}
});
You can also let your activity implements the OnCheckedChangeListener interface and then:
CheckBox check1 = findViewById(R.id.sprint_checkbox);
CheckBox check2 = findViewById(R.id.marathon_checkbox);
CheckBox check3 = findViewById(R.id.never_ending_checkbox);
check1.setOnCheckedChangeListener(this);
check2.setOnCheckedChangeListener(this);
check3.setOnCheckedChangeListener(this);
Overriding the interface method:
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
switch(buttonView.getId()){
case R.id.sprint_checkbox:
//do stuff
break;
case R.id.marathon_checkbox:
//do stuff
break;
case R.id.never_ending_checkbox:
//do stuff
break;
}
}
