Android Development: Checkbox setChecked not working

Question

In my xml:

<CheckBox android:id="@+id/checkboxUpdateLessonPlanAll"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/chkLessonPlanAll"
            android:onClick="onCheckboxClicked"/>

In my java:

public void onCheckboxClicked(View view) {
    //CheckBox box = (CheckBox) view;
    CheckBox box = (CheckBox) findViewById(R.id.checkboxUpdateLessonPlanAll);
    box.setChecked(!box.isChecked());
    Log.v("qwerty", "checkbox clicked " + box.isChecked() + "!!");
}

I see my log message in LogCat and it shows it as false when I click on this flag, but its status does not change. It remains untested.

Answer 1

Why are you trying to overwrite the default behavior with something like the default behavior? The checkbox automatically switches to every click.

If you want to respond to this, use OnCheckedChangeListener.

Answer 2

To make CheckBoxmarked or unchecked, you can also use as

box.setChecked(true);

box.setChecked(false);

and get a fortune CheckBox

if(box.isChecked()) {

  //do something here...

} else {

  //do something here...

}
