Help to deal with sorting / filter ArrayAdapter'a

I have this adapter:

public class DrugAdapter extends ArrayAdapter { Context ctx; LayoutInflater lInflater; ArrayList<InfectionModel> im; public DrugAdapter(Context ctx, ArrayList<InfectionModel> im) { super(ctx, R.layout.drug_list, im); this.ctx = ctx; this.im = im; lInflater = (LayoutInflater) ctx .getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public int getCount() { return im.size(); } @Override public Object getItem(int position) { return im.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { View view = convertView; if (view == null) { view = lInflater.inflate(R.layout.drug_list, parent, false); } String title = im.get(position).getTitle(); ImageView img; String liter = im.get(position).getTitle().substring(0, 1); //int color = new RandomColor().getMatColor("500"); TextDrawable drawable = TextDrawable.builder() .beginConfig() .textColor(Color.WHITE) .useFont(Typeface.DEFAULT) .toUpperCase() .endConfig() .buildRound(liter, MaterialColorPalette.getRandomColor("100")); ((TextView) view.findViewById(R.id.txt)).setText(Html.fromHtml(title)); img = (ImageView) view.findViewById(R.id.image_view); img.setImageDrawable(drawable); return view; }

Well, the InfectionModel itself:

 private String id; private String content; private String title; private String prew; private String date; private String url_img; public InfectionModel() { } public InfectionModel(String id, String content, String title, String prew, String date, String url_img) { this.id = id; this.content = content; this.title = title; this.prew = prew; this.date = date; this.url_img = url_img; } public String getId() { return id; } public void setId(String id) { this.id = id; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public String getPrew() { return prew; } public void setPrew(String prew) { this.prew = prew; } public String getDate() { return date; } public void setDate(String date) { this.date = date; } public String getUrl_img() { return url_img; } public void setUrl_img(String url_img) { this.url_img = url_img; }

As I understand it, Filter is out of the box for him because when I call

 da.getFilter().filter(charSequence.toString().toLowerCase());

Alas, nothing happens, tell me how you can override the getFilter method so that the sorting works correctly? (Sort by field title)

    It is necessary when getting all models (sampling from the database), in the place where you get ArrayList<InfectionModel> im , to add sorting when choosing from the Database.

    If it is ActiveAndroid, then the code will be like this, approximately:

      return new Select() .from(InfectionModel.class) .where("_id >= 0") .orderBy("Title DESC") //или ASC .execute();

    If just a cursor, then something like this:

     Cursor c = database.query(DATABASE_TABLE, rank, null, null, null, null, "Title DESC"); //или Title ASC
    • This is a sort in ListView when entering text in EditText. I work with the database in a different part of the application and does not affect InfectionModel - Heaven
