Required variable, found value?

Question

I got an error by using this code

 holder.box.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            boolean newState = !arrEmps.get(position).isChecked();
            arrEmps.get(position).isChecked() = newState;
            Toast.makeText(mContext.getApplicationContext(),
                    arrEmps.get(position).getName() + "check" + newState,
            Toast.LENGTH_LONG).show();
        }
    });

the error line is

arrEmps.get(position).isChecked() = newState;

the error message is

Error:(86, 48) error: unexpected type
required: variable
found:    value

Answer 1

I think you are using a default method from a clickable item, if so read this, if not go on

Referring to the Clickable interface, you can see that there are two methods:

isChecked()

is a getter and it only returns the value of the checked variable, as you can see inspecting(ie: it tells you whether a checkbox is checked or not):

@ViewDebug.ExportedProperty
@Override
public boolean isChecked() {
    return mChecked;
}

There is also a setter,

setChecked(boolean checked)

This setter set the value of the property of the checked state of the clickable interface. (ie: is set a checkbox as checked or not)

If you are not using a default clickable item/view, but you have your own method

If the object you are using is a custom one, create a setter for the property you want to set by adding a setChecked(boolean value) method

public void setChecked(boolean value){
  mValue = value;
}

here you can learn how to create getters and setters quickly

And I always reccomend this tutorial (imo the best) for learning android basics.

Hope this helps
