How to set Dynamic position of Toast to a View?

First of all this is not complete code

@Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
    {
        Toast toast=Toast.makeText(getApplicationContext(), "", Toast.LENGTH_SHORT);
        toast.setGravity(Gravity.CENTER_HORIZONTAL, 0, 0); 
        View view=toast.getView();
        switch(buttonView.getId())
        {
            case R.id.chkRed: if(chkRed.isChecked())
            {   
                              chkGreen.setChecked(false);
                              chkBlue.setChecked(false);
                              chkYellow.setChecked(false);
                              toast.setText("You Selected Red");
                                toast.setGravity(Gravity.NO_GRAVITY,buttonView.getRight(), chkRed.getTop());
                             //top does not align
                             //it align perfectly to right of checkbox
                              view.setBackgroundColor(Color.RED);
            }
                             break;
}
}

So now the problem is that I want to display toast beside checkbox, I tried working with setGravity(), but it just does not workup and have been hit and trying for long time, but with no progress
