I need to show list of places in dropdown using google placeAutocomplete widgets. Here I\'m getting dialog to show places according to my query but

You need to customize your adapter. I had implemented this functionality in my project. You can follow this.

Customized view that you want to show in your adapter
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/predictedRow" android:layout_width="match_parent" android:layout_height="65dp" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_centerVertical="true" android:gravity="center_vertical"> <ImageView android:id="@+id/image" android:layout_width="22dp" android:layout_height="22dp" android:src="@drawable/ic_action_navigate" android:layout_marginLeft="10dp" android:layout_marginTop="20dp" /> <TextView android:id="@+id/address" android:layout_width="match_parent" android:layout_height="wrap_content" android:textColor="#000" android:textSize="15sp" android:layout_toRightOf="@+id/image" android:layout_centerVertical="true" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" /> <View android:layout_width="match_parent" android:layout_height="1dp" android:background="@color/light_gray" android:layout_alignParentBottom="true"/> </RelativeLayout>Hope it will help you too.
Note: Do not forget to add API key in your
manifestfile.Output will be like:

You just need to create new arraylist every time in filter object
@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; }讨论(0) -
