copied!<p>Sorry about this guys. This must be like the third question I've had to ask about this project alone. =(</p> <p>What i want to be able to do is toggle the visibility of a radio button using a check box in a preferences activity.</p> <p>There are no errors in my code and both activities run fine, but there is no change in visibility when the check box is checked or unchecked.</p> <p>Here is my Activity with the radiobuttons</p> <pre><code>import android.app.Activity; import android.content.SharedPreferences; import android.os.Bundle; import android.preference.PreferenceManager; import android.view.View; import android.widget.EditText; import android.widget.RadioButton;

} else { btn01.setVisibility(View.GONE); } } }); }; }); }} </code></pre> <p>Sorry there is other stuff in there as well such as an analytics plug in</p> <p>Anyone have any idea as to why this just isn't working</p> <p>(Just a side note. When looking at the logcat, clicking the checkbox returned no results)</p> <p><strong>EDIT:</strong> OK i've just ammended my code as suggested but i'm afraid that the preferences still do not affect anything. Anybody have any ideas?? =(</p>
