解决方法@H_403_16@
在Android中我们可以这样限制:
在代码中添加AutoCompletionFilter而不是传递null
限制谷歌自动补充到澳大利亚.
AutocompleteFilter filter =
new AutocompleteFilter.Builder().setCountry("AU").build();
将结果限制为的国家/地区.这应该是ISO 3166-1 Alpha-2国家/地区代码(不区分大小写).如果未设置,则不会进行国家/地区过滤.
请参阅此链接以获取不同的国家代码https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2
@Saipraneeth Nandi纠正你的代码行如下:
mPlaceArrayAdapter =
new PlaceArrayAdapter(this,filter);
