我想过滤搜索ListView，但不存在类getFilter（）。filter

Question

我希望过滤搜索ListView但不存在类`getfilter（）

我已经在网站上研究过应该寻求这些方法。我已阅读，但我没有得到getfilter()

谁能帮助我？ （对不起，我不会说英语好，只能看懂）

public class List_bimar extends ListActivity {
    TextView bimar_id;
    EditText editsearch;

    @Override
    protected void attachBaseContext(Context newBase) {
        super.attachBaseContext(CalligraphyContextWrapper.wrap(newBase));
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sabte_bimar);
        editsearch = (EditText) findViewById(R.id.btn_search);

        BimarRipo repo = new BimarRipo(this);

        ArrayList<HashMap<String, String>> bimartList =  repo.getbimarList();
        if(bimartList.size()!=0) {

            ListView lv = getListView();
            lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    bimar_id = (TextView) view.findViewById(R.id.bimar_idd);
                    String bimarId = bimar_id.getText().toString();
                    Intent objIndent = new Intent(getApplicationContext(),Bimar_Detail.class);
                    objIndent.putExtra("bimar_id", Integer.parseInt( bimarId));
                    startActivity(objIndent);
                }
            });
            final ListAdapter adapter = new SimpleAdapter( List_bimar.this,bimartList, R.layout.view_bimar_entry, new String[] { "id","namebimar" ,"shomaremeli" }, new int[] {bimar_idd, R.id.bimar_name});
            setListAdapter(adapter);


            editsearch.addTextChangedListener(new TextWatcher() {
                @Override
                public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

                }

                @Override
                public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                    List_bimar.this.getListAdapter().
                }

                @Override
                public void afterTextChanged(Editable editable) {
                    String text = editsearch.getText().toString().toLowerCase(Locale.getDefault());

                }
            });
        }
