I have 3 buttons in a fragment and I want to disable them from the main activity. I have tried to use the bundle option before replace() newfragment but it created other issues. Can a button in a fragment be casted to a main activity ? Something like this. I get the error cannot cast but my entries are incorrect. <pre><code> RedUp = (ButtonControls) getFragmentManager().findFragmentById(R.id.btnRedUP); </code></pre> Here is my main.xml this holds the fragment called rgb_controls <pre><code> <FrameLayout android:id="@+id/rgb_controls" android:layout_width="390dp" android:layout_height="match_parent" android:layout_marginLeft="550dp" android:layout_marginTop="10dp" > </FrameLayout> </code></pre> Here is the button in the fragment xml called button_controls.xml <pre><code> <Button android:id="@+id/btnRedUP" android:layout_width="80dp" android:layout_height="80dp" android:layout_marginLeft="10dp" android:layout_marginTop="80dp" android:text="UP" android:textSize="30dp" /> </code></pre> Here is the fragment actiivty <pre><code> public class ButtonControls extends Fragment { public Button RedUp, RedDn, GreenUp, GreenDn, BlueUp, BlueDn; View view; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { view = inflater.inflate(R.layout.button_controls, container, false); RedUp = (Button) view.findViewById(R.id.btnRedUP); return view; } } </code></pre> Fragment is added using the replace() <pre><code> Fragment ButtonFragment = new ButtonControls(); ButtonFragment.setArguments(bundle); FragmentManager fm = getSupportFragmentManager(); FragmentTransaction ft = fm.beginTransaction(); ft.replace(R.id.rgb_controls, ButtonFragment).addToBackStack(null).commit(); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
