Before space:

After the space:

I looked through https://developers.google.com/places/documentation/autocomplete but I did not find anything to help me.

Answer 1

Try to add

 adapter.notifyDataSetChanged(); 

after

 atvPlaces.setAdapter(adapter); 

Answer 2

I was just experimenting with some search results:

https://maps.googleapis.com/maps/api/place/autocomplete/json?input=123+43+Sweden&types=%28regions%29&sensor=false&key=AIzaSyDcXFSC2I6ZqxQeAbUMFvJKMrA98217H9U

URL encoding may be incorrectly encoded. If you have something like "123+" in get, it should return the correct result, as you see above. Instead, you need to do a replacement to replace the seats instead of +.

 input=input.replace(" ","+"); 

Try to keep your encoding after your URLEncoder, but remove any risk of encoding +.

Answer 3

Try "." instead of space. You must replace the space with a period (.). If it does not work, you should try "\", as in ubuntu. May be useful

Answer 4

try replacing this line

  input = "input=" + URLEncoder.encode(place[0], "utf-8"); 

by

  input = "input=" + URLEncoder.encode(place[0]); 

Answer 5

I love the solution, there is nothing wrong with TextWatcher ().

you must use the code below In the code below, I did not override the "performFiltering" method, I added it, and my automatic full text field now works fine.

Public class CustomAutoCompleteView extends AutoCompleteTextView {

 public CustomAutoCompleteView(Context context) { super(context); // TODO Auto-generated constructor stub } public CustomAutoCompleteView(Context context, AttributeSet attrs) { super(context, attrs); // TODO Auto-generated constructor stub } public CustomAutoCompleteView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); // TODO Auto-generated constructor stub } @Override protected void performFiltering(final CharSequence text, final int keyCode) { String filterText = ""; super.performFiltering(filterText, keyCode); } /** * After a selection, capture the new value and append to the existing * text */ @Override protected void replaceText(final CharSequence text) { super.replaceText(text); } 

}
