Android Google Places API
中的自动完成小部件服务未按预期工作。我已将片段包含在我的xml页面中,并且还将侦听器活动添加到我的onCreate()
。
然后我开始执行自动完成片段,点击我要搜索的单词的第一个字母,然后突然显示onError()
被执行并关闭的建议。
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.akhil.maplocation.MapsActivity" />
<fragment
android:id="@+id/place_autocomplete_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"
/>
</RelativeLayout>
主要活动是:
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
LatLng fromadd;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment)
getFragmentManager().findFragmentById(R.id.place_autocomplete_fragment);
autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
// TODO: Get info about the selected place.
fromadd = place.getLatLng();
double lat = fromadd.latitude;
double lng = fromadd.longitude;
gotoLocation(lat, lng, 15);
}
@Override
public void onError(Status status) {
// TODO: Handle the error.
Toast.makeText(getBaseContext(),"failure",Toast.LENGTH_LONG).show();
}
});
mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
@Override
public void onMapClick(LatLng latLng) {
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(latLng);
fromadd = latLng;
markerOptions.title(latLng.latitude + ":" + latLng.longitude + " " + latLng.toString());
mMap.clear();
mMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
mMap.addMarker(markerOptions);
}
});
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
mMap.setMyLocationEnabled(true);
}

您可能会错过使用Google Places API所需的API密钥。查看this link。当您执行链接中指定的所有内容时,也请将此代码添加到AndroidManifest
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="YOUR_KEY" />

mMap,如下所示:
private void gotoLocation(double lat, double lng, int i) {
// TODO Auto-generated method stub
Marker myMarker = map.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.home))
.position(p1)
.snippet("Lat:" + lat + "Lng:" + lng)
.title("HOME"));
map = ((MapFragment) getFragmentManager()
.findFragmentById(R.id.map2)).getMap();
map.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(lat, lng), i));
}
