try this

proactives.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            if(b)
            {
                proactives.setTag("Y");
            }
            if(proactives.isChecked()==false)
            {
                proactives.setTag("N");
            }
        }
    });

OR

proactives.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
              proactives.setTag(b? "Y" : "N"); 
            }
        });

proactives.isChecked()==true is not necessary, since isChecked already returns a boolean, which you are comparing with true. Also, since boolean b represents the checked value, doing proactives.isChecked() is also not needed, you could replace all that code with if (b) {...}else{...} – 2Dee Mar 20 '15 at 10:41

you can use OnCheckedChangeListener

proactives.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            // change your tag here
        }
    });

Use CompoundButton.OnCheckedChangeListener :

proactives.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

       @Override
       public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
           // use isChecked value here to react to state changes on your checkbox
       }
   }
);

give onclick in layout file

<CheckBox
    android:id="@+id/edt_proactive"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:onClick="itemClicked" />

in your activity do this

public void itemClicked(View v) {
    if (((CheckBox) v).isChecked()) {
        proactives.setTag("Y");
    }else{
        proactives.setTag("N");
}

The original formatting of the answer was incorrect, text was included in code blocks and code indentation was also messed up, so I corrected it for readability – 2Dee Mar 20 '15 at 10:42

proactives=(CheckBox)findViewById(R.id.edt_proactive);
proactives.setTag(proactives.isChecked() ? "Y" : "N");
