Cannot Resolve symbol 'isChecked()'

I am trying to check whether the radio button is checked or not. On basis of that, I will trigger some actions. I searched and found out "isChecked" is the method to do so. I use that method but the android studio says Cannot Resolve symbol 'isChecked()'.

enter image description here

<CheckBox
        android:id="@+id/cream"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:layout_marginBottom="10dp"
        android:checked="false"

        android:paddingLeft="26dp"
        android:text="Whipped Cream"
        android:textSize="16sp" />

final CheckBox box = (CheckBox) findViewById(R.id.cream);
     if (box.isChecked())
     {
    box.setChecked(false);
}

Thank you in advance.

import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.CheckBox;
import android.widget.TextView;
import androidx.appcompat.app.AppCompatActivity;

Having a similar problem now, with v

final CheckBox whipped_cream_variable = (CheckBox) findViewById(R.id.whipped_cream);
boolean whipped_cream_has = whipped_cream_variable.isChecked();
Log.v("MainActivity", "Has whipped cream:" + whipped_cream_has);
Solution

  • Dan Baruch solved the problem

    1. try cleaning and rebuilding the project and
    2. Try to put the statement in the trigger button
