    <p>When I touch the screen, the OnTouch method is called twice. So the Intent of the new activity in the method "showdetails" load the activity with the view associated twice also. Why? I just need one...</p> <pre><code>public class DeptFragment extends Fragment implements OnTouchListener { Context mContext = getActivity(); ImageView cacheImage,targetImage; ListView List; ArrayList&lt;String&gt; tabDepartement; ArrayList&lt;String&gt; tabCommunes; int codeDepartementCrt; Departement DepartementCrt; List&lt;Commune&gt; listCommuneCrt; Bundle nomBundle; public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { super.onCreateView(inflater, container, savedInstanceState) ; return inflater.inflate(R.layout.dept_fragment, container, false); } @Override public void onActivityCreated(Bundle savedState) { super.onActivityCreated(savedState); mContext=getActivity(); View mView = getView(); targetImage = (ImageView) mView.findViewById(R.id.targetDeptImage); targetImage.setOnTouchListener(this); } public boolean onTouch(View v, MotionEvent event) { View mView = getView(); ImageView imageView = (ImageView) mView.findViewById(R.id.cacheDeptImage); Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap(); int pixel = bitmap.getPixel((int) event.getX(),(int) event.getY()); int redValue = Color.red(pixel); int blueValue = Color.blue(pixel); int greenValue = Color.green(pixel); showDetails(redValue,greenValue,blueValue); return true; </code></pre> <p>}</p> <pre><code>/** * Helper function to show the details of a selected item, by starting a * whole new activity in which it is displayed. */ void showDetails(int red, int green, int blue) { DepartementCrt=rechercherDepartement(red,green,blue); if (DepartementCrt != null) { Intent intent = new Intent(); intent.setClass(getActivity(), DeptDetailActivity.class); intent.putExtra("code", DepartementCrt.Code); startActivity(intent); } } private Departement rechercherDepartement(int redValue, int greenValue, int blueValue) { DepartementRepository departementRepository=new DepartementRepository(mContext); Departement departement; departementRepository.Open(); departement= departementRepository.rechercherDepartement(redValue, greenValue, blueValue); departementRepository.Close(); return departement; } </code></pre> <p>}</p>

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.
