How do we search the list of SimpleAdapter with ViewBinder?

[chanisef]

You can't use a search method. onTextChanged()

MainActivity.this.sAdapter.getFilter().filter(cs);// cannot find symbol variable sAdapter

Class:

public class MainActivity extends AppCompatActivity {
EditText mSearch;
final String ATTRIBUTE_NAME_TEXT = "text";
final String ATTRIBUTE_NAME_PB = "pb";
final String ATTRIBUTE_NAME_LL = "ll";

ListView lvSimple;


public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    int load[] = { 41, 48, 22, 35, 30, 67, 51, 88 };

    ArrayList<Map<String, Object>> data = new ArrayList<Map<String, Object>>(
            load.length);
    Map<String, Object> m;
    for (int i = 0; i < load.length; i++) {
        m = new HashMap<String, Object>();
        m.put(ATTRIBUTE_NAME_TEXT, "Day " + (i+1) + ". Load: " + load[i] + "%");
        m.put(ATTRIBUTE_NAME_PB, load[i]);
        m.put(ATTRIBUTE_NAME_LL, load[i]);
        data.add(m);
    }

    String[] from = { ATTRIBUTE_NAME_TEXT, ATTRIBUTE_NAME_PB,
            ATTRIBUTE_NAME_LL };

    int[] to = { R.id.tvLoad, R.id.pbLoad, R.id.llLoad };

    SimpleAdapter sAdapter = new SimpleAdapter(this, data, R.layout.item,
            from, to);

    sAdapter.setViewBinder(new MyViewBinder());
    lvSimple = (ListView) findViewById(R.id.lvSimple);
    lvSimple.setAdapter(sAdapter);

    //--------------- addTextChangedListener() -------------------------------
    mSearch = (EditText) findViewById(R.id.mSearch);
    mSearch.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {

            //Error: cannot find symbol variable sAdapter
            MainActivity.this.sAdapter.getFilter().filter(cs);
        }

        @Override
        public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                                      int arg3) {
            // TODO Auto-generated method stub

        }

        @Override
        public void afterTextChanged(Editable arg0) {
            // TODO Auto-generated method stub
        }
    });
}// End onCreate()

class MyViewBinder implements SimpleAdapter.ViewBinder {

    int red = getResources().getColor(R.color.Red);
    int orange = getResources().getColor(R.color.Orange);
    int green = getResources().getColor(R.color.Green);

    @Override
    public boolean setViewValue(View view, Object data,
                                String textRepresentation) {
        int i = 0;
        switch (view.getId()) {
            // LinearLayout
            case R.id.llLoad:
                i = ((Integer) data).intValue();
                if (i < 40) view.setBackgroundColor(green); else
                if (i < 70) view.setBackgroundColor(orange); else
                    view.setBackgroundColor(red);
                return true;
            // ProgressBar
            case R.id.pbLoad:
                i = ((Integer) data).intValue();
                ((ProgressBar)view).setProgress(i);
                return true;
        }
        return false;
    }
}

You've got a local variable method adapter. onCreatethe class doesn't know anything about her. So either

final SimpleAdapter sAdapter = new SimpleAdapter(this, data, R.layout.item,
            from, to);

and

sAdapter.getFilter().filter(cs); // MainActivity.this - убрать

or make sAdapter the variable class MainActivity

private SimpleAdapter sAdapter;

and

sAdapter = new SimpleAdapter(this, data, R.layout.item,
            from, to);
