How to create a SearchView with Filter mode in a ListView in Android?

By | June 1, 2013

Actually this is fairly simple.
Android by default provides a SearchView class that has the ability to filter.

Just look at the XML layout that I am using in this post.
It consists of a SearchView and a ListView. The searchView searches the listview for the matched content.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
    <SearchView
            android:id="@+id/search_view"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
    <ListView
            android:id="@+id/list_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"/>

</LinearLayout>

Now the Java class or the activity that implements the searchFilter.

package com.coderzheaven.searchviewwithfilter;

import android.app.Activity;
import android.os.Bundle;
import android.text.TextUtils;
import android.view.Window;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.SearchView;

/**
 * Shows a list that can be filtered in-place with a SearchView in non-iconified mode.
 */
public class SearchViewFilterMode extends Activity implements SearchView.OnQueryTextListener {

    private SearchView mSearchView;
    private ListView mListView;

    private final String[] mStrings = Cheeses.sCheeseStrings;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().requestFeature(Window.FEATURE_ACTION_BAR);

        setContentView(R.layout.searchview_filter);

        mSearchView = (SearchView) findViewById(R.id.search_view);
        mListView = (ListView) findViewById(R.id.list_view);
        mListView.setAdapter(new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1,
                mStrings));
        mListView.setTextFilterEnabled(true);
        setupSearchView();
    }

    private void setupSearchView() {
        mSearchView.setIconifiedByDefault(false);
        mSearchView.setOnQueryTextListener(this);
        mSearchView.setSubmitButtonEnabled(true); 
        mSearchView.setQueryHint("Search Here");
    }

    public boolean onQueryTextChange(String newText) {
        if (TextUtils.isEmpty(newText)) {
            mListView.clearTextFilter();
        } else {
            mListView.setFilterText(newText.toString());
        }
        return true;
    }

    public boolean onQueryTextSubmit(String query) {
        return false;
    }
}
