J'ai créé une application avec une feuille de fond qui utilise des feuilles de fond avec une vue de liste.Bottomsheet ListAfficher seulement 1 élément
Auparavant, j'ai utilisé un recyclerView pour afficher les éléments de liste d'une liste de tableaux, dans la partie inférieure de la feuille. Maintenant, j'ai changé l'application pour utiliser un listView à la place, en récupérant des données d'un curseur.
Maintenant, la feuille inférieure montre un seul élément:
Même dans l'aperçu studio android, je ne peux voir 1 objet de liste:
J'ai créé une activité de test avec une vue de liste unique, et toutes les données sont affichées, sauf pour le fait que chaque troisième élément est "déformé".
Voici le code pour l'activité de mise en page:

Enfin, est ici le code pour le Main Activité:

.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
LinearLayout bottomsheet =
findViewById(R.id.bottomsheet);
mBottomsheetbehvior = BottomSheetBehavior.from(bottomsheet);
mBottomsheetbehvior.setHideable(true);

mBottomsheetbehvior.setState(BottomSheetBehavior.STATE_HIDDEN);

eventListButton.setOnClickListener(new View.OnClickListener() {
@Override

});

}
@Override

});
final ListView eventListView = (ListView) findViewById(R.id.eventlistview);
final DatabaseHelper eventManager = new DatabaseHelper(context);
Thread thread = new Thread(new Runnable(){
@Override
public void run(){
eventCursor = eventManager.getAllEvents();
eventListCursorAdapter = new EventListCursorAdapter(
MainActivity.this,
eventCursor,
0);
eventListView.setAdapter(eventListCursorAdapter);
}
});
thread.start();
}
@Override
public void onMapReady(GoogleMap googleMap) {
//Stuff
}
public void moveCamera(LatLng location){
final CameraPosition movelocation = CameraPosition.builder().
target(location).zoom(14).build();
MainActivity.mMap.animateCamera(CameraUpdateFactory.newCameraPosition(movelocation));
}
}
Si elle aide, voici le code pour l'adaptateur du curseur:
public class EventListCursorAdapter extends CursorAdapter {
private LayoutInflater cursorInflater;
Calculations calculations = new Calculations();
Gson gson = new Gson();
Context AppContext;
public EventListCursorAdapter(Context context, Cursor c, int flags) {
super(context, c, flags);
cursorInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
AppContext = context.getApplicationContext();
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return cursorInflater.inflate(R.layout.card_view, parent, false);
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
TextView timeText = (TextView) view.findViewById(R.id.event_time);
TextView nameText = (TextView) view.findViewById(R.id.event_name);
TextView dateText = (TextView) view.findViewById(R.id.event_date);
TextView summaryText = (TextView) view.findViewById(R.id.event_summary);
TextView participantsText = (TextView) view.findViewById(R.id.event_participantNum);
TextView locationText = (TextView) view.findViewById(R.id.event_location);
final Cursor mCursor = cursor;
String date = calculations.UnixTimeConverter(
mCursor.getLong(mCursor.getColumnIndex(DatabaseHelper.COL_UNIXTIME)
))[0];
String time = calculations.UnixTimeConverter(
mCursor.getLong(mCursor.getColumnIndex(DatabaseHelper.COL_UNIXTIME))
)[1];
final LatLng location = gson.fromJson(mCursor.getString(mCursor.getColumnIndex(DatabaseHelper.COL_LOCATION)),LatLng.class);
nameText.setText(mCursor.getString(mCursor.getColumnIndex(DatabaseHelper.COL_NAME)));
dateText.setText(date);
timeText.setText(time);
participantsText.setText(mCursor.getInt(mCursor.getColumnIndex(DatabaseHelper.COL_PARTICIPANTS))+"");
summaryText.setText(mCursor.getString(mCursor.getColumnIndex(DatabaseHelper.COL_SUMMARY)));
locationText.setText(mCursor.getString(mCursor.getColumnIndex(DatabaseHelper.COL_LOCATIONNAME)));
locationText.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
final CameraPosition camLocation = CameraPosition.builder().
target(location).zoom(18).build();
MainActivity.mMap.animateCamera(CameraUpdateFactory.newCameraPosition(camLocation));
}
});
summaryText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
LayoutInflater mLayoutInflator;
mLayoutInflator = LayoutInflater.from(AppContext);
final AlertDialog.Builder mBuilder = new AlertDialog.Builder(mContext);
View mView = mLayoutInflator.inflate(R.layout.summarydialog,null);
TextView textView = mView.findViewById(R.id.mainText);
textView.setText(
mCursor.getString(mCursor.getColumnIndex(DatabaseHelper.COL_SUMMARY))
);
textView.setMovementMethod(new ScrollingMovementMethod());
mBuilder.setView(mView);
final AlertDialog dialog = mBuilder.create();
dialog.show();
}
});
}
}
Il sera utile si vous pouviez dire comment avoir la feuille inférieure listview afficher toutes les données du curseur, sans avoir une partie de les éléments de la liste étant "déformés" comme dans la deuxième image
