android - 在谷歌地图上添加搜索工具栏，就像在原生 android 应用程序中一样

Question

我想在本地谷歌地图应用中实现搜索工具栏。我怎样才能做到这一点？可能有实现此功能的本地方式吗？

Answer 1

您可以使用 EditText 或 TextWatcher。我使用了一个 EditText 和一个搜索按钮。点击这个按钮，它会搜索位置。

这是我点击按钮的代码:

button1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            String g = searchview.getText().toString();

            Geocoder geocoder = new Geocoder(getBaseContext());
            List<Address> addresses = null;

            try {
                // Getting a maximum of 3 Address that matches the input
                // text
                addresses = geocoder.getFromLocationName(g, 3);
                if (addresses != null && !addresses.equals(""))
                    search(addresses);

            } catch (Exception e) {

            }

        }
    });

这里是搜索方法

protected void search(List<Address> addresses) {

    Address address = (Address) addresses.get(0);
    home_long = address.getLongitude();
    home_lat = address.getLatitude();
    latLng = new LatLng(address.getLatitude(), address.getLongitude());

    addressText = String.format(
            "%s, %s",
            address.getMaxAddressLineIndex() > 0 ? address
                    .getAddressLine(0) : "", address.getCountryName());

    markerOptions = new MarkerOptions();

    markerOptions.position(latLng);
    markerOptions.title(addressText);

    map1.clear();
    map1.addMarker(markerOptions);
    map1.moveCamera(CameraUpdateFactory.newLatLng(latLng));
    map1.animateCamera(CameraUpdateFactory.zoomTo(15));
    locationTv.setText("Latitude:" + address.getLatitude() + ", Longitude:"
            + address.getLongitude());


}
