So i tried implementing a search bar to my app for my listview and it does work but it only takes the first result in a array. I am using a custom array adapter and I am going crazy trying to figure this out.
This is where the listview is called and where i added the editview code. I followed a simple youtube tutorial and I tried looking for solutions for custom array adapter and they are so confusing for me.
package com.example.android.g4_project;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ListView;
import com.google.android.libraries.places.api.Places;
import java.util.ArrayList;
public class DisplayRestaurants extends AppCompatActivity {
private ListView mListView;
private static final String API_KEY = "my api key";
public static final String restaurantLat = "Restaurant Latitude";
public static final String restaurantLong = "Restaurant Longitude";
public static final String placeName = "Restaurant Name";
public static final String placeAddress = "Restaurant Address";
public static final String placeID = "Restaurant PlaceID";
public static final String currentLat = "Current Latitude";
public static final String currentLng = "Current Longitude";
private static ArrayList<Double> latList, lngList;
private static ArrayList<String> restName;
private static ArrayList<String> restAddress;
private static ArrayList<String> restPlaceID;
private ArrayAdapter adapter;
private Double devLat;
private Double devLng;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_restaurants);
Places.initialize(getApplicationContext(), API_KEY);
EditText theFilter = (EditText) findViewById(R.id.searchFilter);
getRestData mm = new getRestData();
restName = mm.getRestName();
restAddress = mm.getRestAddress();
restPlaceID = mm.getRestPlaceID();
latList = mm.getLatList();
lngList = mm.getLngList();
devLat = mm.getDevLat();
devLng = mm.getDevLng();
ArrayList<String> list = restName;
if (list != null) {
String[] values = list.toArray(new String[list.size()]);
mListView = findViewById(R.id.listView);
adapter = new PlaceImageListView(this, values);
mListView.setAdapter(adapter);
theFilter.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
DisplayRestaurants.this.adapter.getFilter().filter(s);
}
@Override
public void afterTextChanged(Editable s) {
}
});
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
int pos = mListView.getPositionForView(view);
if (position == pos) {
Intent restInfo = new Intent(DisplayRestaurants.this, restaurantInfo.class);
Double lat = latList.get(pos);
Double lng = lngList.get(pos);
String restAddr = restAddress.get(pos);
String restTitle = restName.get(pos);
String restID = restPlaceID.get(pos);
restInfo.putExtra(restaurantLat, lat);
restInfo.putExtra(restaurantLong, lng);
restInfo.putExtra(placeAddress, restAddr);
restInfo.putExtra(placeName, restTitle);
restInfo.putExtra(placeID, restID);
restInfo.putExtra(currentLat, devLat);
restInfo.putExtra(currentLng, devLng);
startActivity(restInfo);
}
}
});
}
}
}
This is my custom array adapter that displays images next to my listview. I had to hardcode it because I have no clue on how to do it more efficiently. There are 60 strings but I only included 2 in the post.
