Android Listview Search Filter

IIIGeorgeIII · 2016-09-03T09:04:33+0200

Gute Tag an alle, ;-) ich hoffe ihr könnt mir da weiter Helfen

Folgendes Problem:
In meiner App möchte Ich auf bestimmten Artikel klicken die nach Filterung abgeschlossen wurde, das Problem ist, dass nach dem Filtern die Position der einzelnen Klassen nicht mehr zu einender passen.

Code:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activitypz_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar8);
        setSupportActionBar(toolbar);

        List<HashMap<String, String>> aList = new ArrayList<HashMap<String, String>>();

        for (int i = 0; i < fahrzeuge.length; i++) {
            HashMap<String, String> hm = new HashMap<String, String>();
            hm.put("listview_title", fahrzeuge[i]);
            hm.put("listview_discription", einheit[i]);
            hm.put("listview_image", Integer.toString(imgid[i]));
            aList.add(hm);
        }

        String[] from = {"listview_image", "listview_title", "listview_discription"};
        int[] to = {R.id.iconpkw, R.id.item, R.id.textViewpkw1011};

        adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.mylistpkw, from, to);
        list = (ListView) findViewById(R.id.list4);
        list.setAdapter(adapter);
        list.setTextFilterEnabled(true);





        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                                    int pos, long id) {

                String openClass =  fahrzeuge[pos];

                if (openClass.equals("Fuchs")) {
                    Intent myIntent = new Intent(view.getContext(), FuchsActivity.class);
                    startActivityForResult(myIntent, 0);
                }else if (openClass.equals("Boxer")) {
                    Intent myIntent = new Intent(MainActivityPz.this, BoxerActivity.class);
                    startActivityForResult(myIntent, 0);
                }else if (openClass.equals("Dingo I")) {
                    Intent myIntent = new Intent(view.getContext(), DingoeinsActivity.class);
                    startActivityForResult(myIntent, 0);
                }else if (openClass.equals("Biber")) {
                    Intent myIntent = new Intent(MainActivityPz.this, BiberActivity.class);
                    startActivityForResult(myIntent, 0);
                }else if (openClass.equals("Dingo 2 GE A2")) {
                    Intent myIntent = new Intent(MainActivityPz.this, DingoZweiAActivity.class);
                    startActivityForResult(myIntent, 0);
                }else if (openClass.equals("Dingo 2 GE C1 GSI")) {
                    Intent myIntent = new Intent(view.getContext(), DingoZweiCActivity.class);
                    startActivityForResult(myIntent, 0);
                }else if (openClass.equals("Fennek STF Lu/Bo")) {
                    Intent myIntent = new Intent(MainActivityPz.this, FennekActivity.class);
                    startActivityForResult(myIntent, 0);
                }else if (openClass.equals("Leopard 2")) {
                    Intent myIntent = new Intent(MainActivityPz.this, LeopardActivity.class);
                    startActivityForResult(myIntent, 0);
                }else if (openClass.equals("Spz Marder")) {
                    Intent myIntent = new Intent(MainActivityPz.this, MarderActivity.class);
                    startActivityForResult(myIntent, 0);
                }else if (openClass.equals("Mars II")) {
                    Intent myIntent = new Intent(MainActivityPz.this, MarszweiActivity.class);
                    startActivityForResult(myIntent, 0);
                }



            }
        });
 }

Hallo George,

nimm am Besten einen eigenen CustomAdapter und diesem übergibst du eine KlassenStruktur in einem Array(List)
Sortieren kannst du dann ggf. mit "Collections"

Hi , Danke für den Tipp, kannst du mir vielleicht ein gutes tutorial empfehlen ?

swa00 · 2016-09-03T10:08:33+0200

Schau mal hier,
das bezieht sich zwar jetzt auf einen GridView verdeutlicht dir aber , wie man einen Custom-Adapter erstellt und benutzt.

Custom GridView with ImageView and TextView In Android

und anstatt zwei Array zu deklarieren

String[] from = {"listview_image", "listview_title", "listview_discription"};
int[] to = {R.id.iconpkw, R.id.item, R.id.textViewpkw1011};

Machst du z.b sowas

public class _MyStructure
{
String from;
int to;
}

deklarieren :
private ArrayList <_MyStructure> MS;
MS = new ArrayList();

Adden :
_MyStructure ms_tmp = new _MyStructure();
ms_temp.from = "fooo";
ms_tmp.to =foo_value;
MS.add(ms_tmp);

P.S alles nur schnell aus der Hüfte runtergetippt , nicht getestet
