I've retrieve all the data from firebase to recyclerview textview itemview, when I try if else condition in adapter it compare with textview android:text in xml not the firebase data value, why is this happen??

studentName = (TextView) itemView.findViewById(R.id.studentName);

        String name = studentName.getText().toString();
        if(name.equals("a")){
            checkBox.setChecked(true);
        }else{
            checkBox.setChecked(false);
        }

It compares with the textview android:text Name goes here in xml not the firebase value...

<TextView
    android:id="@+id/studentName"
    android:layout_width="205dp"
    android:layout_height="wrap_content"
    android:text="Name goes here"
    android:textColor="#212121"
    android:textSize="15sp" />
