google places android example

Question

Necesito mostrar la lista de lugares en el dropdown usando los widgets de google placeAutocomplete . Aquí obtengo el diálogo para mostrar los lugares de acuerdo con mi consulta, pero debo dar un diseño personalizado para ese diálogo de resultados de búsqueda como en las aplicaciones Uber, Ola. Aquí quiero diseño como imagen abajo. Si alguien ha hecho esto antes, por favor dame tus sugerencias, gracias de antemano.

Answer 3

Solo necesitas crear un nuevo arraylist cada vez en el objeto de filtro.

@Override 
public Filter getFilter() {
    Filter filter = new Filter() {
        @Override 
        protected FilterResults performFiltering(CharSequence constraint) {
            FilterResults results = new FilterResults();
            // Skip the autocomplete query if no constraints are given. 
            if (constraint != null) {
                // Query the autocomplete API for the (constraint) search string. 

               /**You just need to create new object then crash problem 
                 will not occur**/
                mResultList = new ArrayList<>;

                mResultList = getAutocomplete(constraint);
                if (mResultList != null) {
                    // The API successfully returned results. 
                    results.values = mResultList;
                    results.count = mResultList.size();
                } 
            } 
            return results;
        } 

        @Override 
        protected void publishResults(CharSequence constraint, FilterResults results) {
            if (results != null && results.count > 0) {
                // The API returned at least one result, update the data. 
                notifyDataSetChanged(); 
            } else { 
                // The API did not return any results, invalidate the data set. 
                //notifyDataSetInvalidated(); 
            } 
        } 
    }; 
    return filter;
}

Kotlin

fun queryPlaces(text: String) {
    val task = object : AsyncTask<Void,Void,Void>(){
        override fun doInBackground(vararg params: Void?): Void? {
            val results = Places.GeoDataApi.getAutocompletePredictions(mGoogleApiClient, text, null, null)
            val autocompletePredictions = results.await()
            val iterator = autocompletePredictions.iterator()
            while (iterator.hasNext()) {
                val prediction = iterator.next()
                println("PlaceId:${prediction.placeId}")
                println("PrimaryText:${prediction.getPrimaryText(null)}")
            }
            autocompletePredictions.release()
            return null
        }
    }
    task.execute()
}

Si quieres obtener el detalle del lugar:

fun queryPlaces(text: String) {
    val geoDataClient : GeoDataClient = Places.getGeoDataClient(context!!)

    val task = object : AsyncTask<Void,Void,Void>(){
        override fun doInBackground(vararg params: Void?): Void? {
            val results = Places.GeoDataApi.getAutocompletePredictions(mGoogleApiClient, text, null, null)
            val autocompletePredictions = results.await()
            val iterator = autocompletePredictions.iterator()
            while (iterator.hasNext()) {
                val prediction = iterator.next()

                geoDataClient.getPlaceById(prediction.placeId).addOnCompleteListener {task->
                    val places = task.result
                    val myPlace = places?.get(0)
                    println("name:${myPlace?.name}")
                    println("latLng:${myPlace?.latLng}")
                    println("address:${myPlace?.address}")
                }
            }
            autocompletePredictions.release()
            return null
        }
    }
    task.execute()
}
