android listview search baseadapter custom-adapter

I have created a list view with multiple items in row. I have also created a search box above. I want to implement search functionality on the basis of particular fields of the list. How can I achieve this? Any help will be appreciated.

I got solution check bellow link #21476225 – Congeal 15/5, 2014 at 7:10

You have to use model, listview, and customadapter with filtering for this. I have created a demo for this.

Suppose you have a model named Product, and you are displaying its content in a custom listview where name and price are displayed in a textview. I mean in a custom row having two textviews, and you want to filter the list by one of the field of custom row. Here I have filtered with "name"

Model

public class Product {

    public String name;
    public Integer price;
    public Product(String name, Integer price) {
        super();
        this.name = name;
        this.price = price;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getPrice() {
        return price;
    }
    public void setPrice(Integer price) {
        this.price = price;
    }
}

Activity with custom adapter and listview

public class MainActivity extends Activity {
    private LinearLayout llContainer;
    private EditText etSearch;
    private ListView lvProducts;

    private ArrayList<Product> mProductArrayList = new ArrayList<Product>();
    private MyAdapter adapter1;


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


        initialize();



        // Add Text Change Listener to EditText
        etSearch.addTextChangedListener(new TextWatcher() {

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                // Call back the Adapter with current character to Filter
                adapter1.getFilter().filter(s.toString());
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,int after) {
            }

            @Override

How do I modify your code with my BaseAdapter? #20506980 – Siegel 11/12, 2013 at 14:49

@MehulJoisar I was able to modify the code but when I search nothing happens and the ListView just disappears. – Siegel 11/12, 2013 at 15:2

@MehulJoisar The link (#20524917) already has the BaseAdapter code. I am actually using an ArrayAdapter – Siegel 12/12, 2013 at 15:31

Hi ! thanks for the code. Just one think, i think you must add setAdapter to the listView like this : adapter1.getFilter().filter(s.toString()); lvProducts.setAdapter(adapter1); It's doesn't work before, but after I aded it it s work perfectly. – Estate 1/9, 2015 at 19:44

@serabile: you shouldn't do that inside onTextChanged method. Adapter should be set only once and then it should just get filtered only as per code I have posted. – Mitrewort 2/9, 2015 at 11:24

is is possible to implement this using ArrayAdapter instead of baseAdapter bacause I'm having an error in getFilter() function saying there is a clash between this function and the getFilter() in the ArrayAdapter class – Fulani 1/9, 2019 at 10:17

Implement filterable in your customadapter class.

public class MainActivity extends AppCompatActivity {

String names[] = {"Apple","Banana","Kiwi","Oranges","Watermelon"};
String emails[] = {"This is apple","This is banana","This is kiwi","This is oranges","This is watermelon"};
int images[] = {R.drawable.apple,R.drawable.banana,R.drawable.kiwi,R.drawable.oranges,R.drawable.watermelon};

List<ItemsModel> itemsModelList = new ArrayList<>();

ListView listView;

CustomAdapter customAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    listView = findViewById(R.id.listview);


    for(int i = 0;i < names.length;i++){

        ItemsModel itemsModel = new ItemsModel(names[i],emails[i],images[i]);

        itemsModelList.add(itemsModel);

    }

     customAdapter = new CustomAdapter(itemsModelList,this);

    listView.setAdapter(customAdapter);


}


@Override
public boolean onCreateOptionsMenu(Menu menu) {


    getMenuInflater().inflate(R.menu.search_menu,menu);

    MenuItem menuItem = menu.findItem(R.id.searchView);

    SearchView searchView = (SearchView) menuItem.getActionView();

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {

            Log.e("Main"," data search"+newText);

            customAdapter.getFilter().filter(newText);



            return true;
        }
    });


    return true;

}


@Override
public boolean onOptionsItemSelected(@NonNull MenuItem item) {

    int id = item.getItemId();


    if(id == R.id.searchView){

        return true;
    }
    return super.onOptionsItemSelected(item);
}


public class CustomAdapter extends BaseAdapter implements Filterable {

    private List<ItemsModel> itemsModelsl;

BaseAdapter does not have a getLayoutInflater() method – Eller 30/1, 2021 at 12:5

You can set a TextWatcher for your search box and change your Cursor on onTextChanged() on TextWatcher like Codes below :

TextWatcher filterNameTextWatcher = new TextWatcher()
 public void beforeTextChanged(CharSequence s, int start, int count,int after)
        {
        }

        public void onTextChanged(CharSequence s,int start, int before,int count) 
        {
            Cursor FilteredNameList = ZoneCardDBAdapter.instance.CursorFilteredName(s.toString());
            Listadapter.changeCursor(FilteredNameList);


        }

        @Override
        public void afterTextChanged(Editable arg0) 
        {   
        }
    };

EditText filterTextName = (EditText)this.findViewById(R.id.edtZoneCardNameFilter);
filterTextCPName.addTextChangedListener(filterNameTextWatcher);

Hath answered 2/1, 2013 at 7:30 Comment(0)

for this, you first need to add an edittext, where you will type to filter data from the list,

then enable filteration in the list,

editText = (EditText) findViewById(R.id.searchList);
 adapter = new CustomListViewAdapter(this,
                R.layout.list_row, rowItems);
        listView.setAdapter(adapter);
        listView.setTextFilterEnabled(true);

Then you need to add TextChangeListener() for the edittext,

editText.addTextChangedListener(new TextWatcher() {

            public void onTextChanged(CharSequence arg0, int arg1, int arg2,
                    int arg3) {

            }

            public void beforeTextChanged(CharSequence arg0, int arg1,
                    int arg2, int arg3) {

            }

            public void afterTextChanged(Editable arg0) {
                MyActivityName.this.adapter.getFilter().filter(arg0);

            }
        });

but when click on the list it throws the wrong position of arraylist – Tamie 18/1, 2019 at 7:43

Use below kind of method.

your edit text box.addTextChangedListener(new TextWatcher() {
            @Override
            public void onTextChanged(CharSequence s, int start, int before,
                    int count) {
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {
            }

            @Override
            public void afterTextChanged(Editable theWatchedText) {

            }
        });

    }
