A debounce searchview query listener. [DO NOT USE THIS , TRY TO USE RXJAVA]

DebouncedQueryTextListener.java

package com.reqabaweb.healthcontrol.ui;

import android.os.SystemClock;
import android.support.v7.widget.SearchView;
import android.util.Log;


public abstract class DebouncedQueryTextListener implements SearchView.OnQueryTextListener {

    private static final String TAG = "DebouncedOnQueryTextLis";
    private static final long THRESHOLD_MILLIS = 500L;
    private long lastClickMillis;
    private int calls = 0;

    protected DebouncedQueryTextListener() {

    }

    public abstract void onQueryDebounce(String text);

    @Override
    public boolean onQueryTextSubmit(String query) {
        return true;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        long now = SystemClock.elapsedRealtime();
        if (now - lastClickMillis > THRESHOLD_MILLIS) {
            calls += 1;
            onQueryDebounce(newText);
            Log.d(TAG, "onQueryTextChange: " + calls);
        }
        lastClickMillis = now;
        return true;
    }
}

implementation is pretty simple and straightforward

 searchView.setOnQueryTextListener(new DebouncedQueryTextListener() {
            @Override
            public void onQueryDebounce(String text) {
                query(text); // do something with the query
            }
        });
