我正在使用此点读取json后，在地图上显示一些POI的应用程序。 我的应用程序在android 4.4中运行良好，但是当我在android 6（仿真器和真实设备）中运行它时，相机不会在I＆＃m; m设置的水平上进行缩放。 我没有收到任何关于某些弃用命令的错误或警告。
这是MainActivity中的代码
@Override
public void onMapReady(GoogleMap map) {
mapVar = map;
// MapWrapperLayout initialization
final MapWrapperLayout mapWrapperLayout = (MapWrapperLayout) findViewById(R.id.map_relative_layout);
// MapWrapperLayout initialization
mapWrapperLayout.init(map, getPixelsFromDp(this, 39 + 20));
this.infoWindow = (ViewGroup) getLayoutInflater().inflate(R.layout.info_window, null);
this.infoTitle = (TextView) infoWindow.findViewById(R.id.title);
this.infoSnippet = (TextView) infoWindow.findViewById(R.id.snippet);
this.infoButton = (Button) infoWindow.findViewById(R.id.button);
// Setting custom OnTouchListener which deals with the pressed state
// so it shows up
this.infoButtonListener = new OnInfoWindowElemTouchListener(infoButton,
getResources().getDrawable(R.drawable.round_but_green_sel), //btn_default_normal_holo_light
getResources().getDrawable(R.drawable.round_but_red_sel)) //btn_default_pressed_holo_light
{
@Override
protected void onClickConfirmed(View v, Marker marker) {
// Here we can perform some action triggered after clicking the button
//Toast.makeText(MainActivity.this, marker.getTitle() + "'s button clicked!", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(MainActivity.this, dettaglio.class);
//EditText editText = (EditText) findViewById(R.id.edit_message);
String titolo = marker.getTitle();
String idPOI = allMarkersMapIds.get(marker);
String IMGPOI = allMarkersMapImg.get(marker);
String Desc = allMarkersMapDesc.get(marker);
String idUtentePOI = allMarkersMapidUtente.get(marker);
String idCategoria = allMarkersMapidCategoria.get(marker);
LATLON = marker.getPosition();
Bundle args = new Bundle();
args.putParcelable("coordinatePOI", LATLON);
intent.putExtra("bundle", args);
intent.putExtra(EXTRA_MESSAGE, titolo);
intent.putExtra(EXTRA_ID, idPOI);
intent.putExtra(EXTRA_IMG, IMGPOI);
intent.putExtra(EXTRA_Desc, Desc);
intent.putExtra("IDCATEGORIAPOI", idCategoria);
intent.putExtra("IDUTENTEPOI", idUtentePOI);
startActivity(intent);
}
};
this.infoButton.setOnTouchListener(infoButtonListener);
map.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker marker) {
return null;
}
@Override
public View getInfoContents(Marker marker) {
// Setting up the infoWindow with current's marker info
infoTitle.setText(marker.getTitle());
infoSnippet.setText(marker.getSnippet());
infoButtonListener.setMarker(marker);
// We must call this to set the current marker and infoWindow references
// to the MapWrapperLayout
mapWrapperLayout.setMarkerWithInfoWindow(marker, infoWindow);
return infoWindow;
}
});
/// HERE I CENTER AND ZOOM THE CAMERA
CameraPosition googlePlex = CameraPosition.builder()
.target(new LatLng(latitude, longitude))
.zoom(15)
.bearing(0)
.tilt(45)
.build();
setUpMapIfNeeded(0, ricercaString);
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)

// for ActivityCompat#requestPermissions for more details.
return;
}
map.setMyLocationEnabled(true);
map.moveCamera(CameraUpdateFactory.newCameraPosition(googlePlex));
map.animateCamera(CameraUpdateFactory.newCameraPosition(googlePlex), 2000, null);
}
我在侦听位置变化的服务中做同样的事情
@Override
public void onLocationChanged(Location location) {
listPOI = MainActivity.getArrayList();
// a bool value to understand if I can go ahead
goAhead = MainActivity.getGoAhead();
namesPOI = MainActivity.getNamePOI();
range = PrefActivity.getRange();
proximity = PrefActivity.getProximity();
//checks whether the user wants to be notified
if(proximity) {
//check if the list of near POI is loaded
if (goAhead) {
if (utility.isNear(location, listPOI, namesPOI, range)) {
POI = utility.getNamePOI();
String msg = "You're near " + POI;
tts1.tts.speak(msg, TextToSpeech.QUEUE_FLUSH, null);
}
}
}
getLocation();
CameraUpdate center = CameraUpdateFactory.newLatLng(new LatLng(location.getLatitude(),location.getLongitude()));
MainActivity.mapVar.moveCamera(center);
CameraUpdate zoom = CameraUpdateFactory.zoomTo(15);
MainActivity.mapVar.animateCamera(zoom);
}
但变焦仍处于世界水平......有人可以找出原因吗？

好的，我按如下方式更改了onMapReady，现在它可以正常工作。
@Override
public void onMapReady(GoogleMap map) {
mapVar = map;
// MapWrapperLayout initialization
CameraPosition googlePlex = CameraPosition.builder()
.target(new LatLng(latitude, longitude))
.zoom(15)
.bearing(0)
.tilt(45)
.build();
map.animateCamera(CameraUpdateFactory.newCameraPosition(googlePlex), 2000, null);
final MapWrapperLayout mapWrapperLayout = (MapWrapperLayout) findViewById(R.id.map_relative_layout);
// MapWrapperLayout initialization
mapWrapperLayout.init(map, getPixelsFromDp(this, 39 + 20));
this.infoWindow = (ViewGroup) getLayoutInflater().inflate(R.layout.info_window, null);
this.infoTitle = (TextView) infoWindow.findViewById(R.id.title);
this.infoSnippet = (TextView) infoWindow.findViewById(R.id.snippet);
this.infoButton = (Button) infoWindow.findViewById(R.id.button);
// Setting custom OnTouchListener which deals with the pressed state
// so it shows up
this.infoButtonListener = new OnInfoWindowElemTouchListener(infoButton,
getResources().getDrawable(R.drawable.round_but_green_sel), //btn_default_normal_holo_light
getResources().getDrawable(R.drawable.round_but_red_sel)) //btn_default_pressed_holo_light
{
@Override
protected void onClickConfirmed(View v, Marker marker) {
// Here we can perform some action triggered after clicking the button
//Toast.makeText(MainActivity.this, marker.getTitle() + "'s button clicked!", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(MainActivity.this, dettaglio.class);
//EditText editText = (EditText) findViewById(R.id.edit_message);
String titolo = marker.getTitle();
String idPOI = allMarkersMapIds.get(marker);
String IMGPOI = allMarkersMapImg.get(marker);
String Desc = allMarkersMapDesc.get(marker);
String idUtentePOI = allMarkersMapidUtente.get(marker);
String idCategoria = allMarkersMapidCategoria.get(marker);
LATLON = marker.getPosition();
Bundle args = new Bundle();
args.putParcelable("coordinatePOI", LATLON);
intent.putExtra("bundle", args);
intent.putExtra(EXTRA_MESSAGE, titolo);
intent.putExtra(EXTRA_ID, idPOI);
intent.putExtra(EXTRA_IMG, IMGPOI);
intent.putExtra(EXTRA_Desc, Desc);
intent.putExtra("IDCATEGORIAPOI", idCategoria);
intent.putExtra("IDUTENTEPOI", idUtentePOI);
startActivity(intent);
}
};
this.infoButton.setOnTouchListener(infoButtonListener);
map.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker marker) {
return null;
}
@Override
public View getInfoContents(Marker marker) {
// Setting up the infoWindow with current's marker info
infoTitle.setText(marker.getTitle());
infoSnippet.setText(marker.getSnippet());
infoButtonListener.setMarker(marker);
// We must call this to set the current marker and infoWindow references
// to the MapWrapperLayout
mapWrapperLayout.setMarkerWithInfoWindow(marker, infoWindow);
return infoWindow;
}
});
setUpMapIfNeeded(0, ricercaString);
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

return;

map.setMyLocationEnabled(true);

而不是animateCamera＆gt; newCameraPosition使用moveCamera＆gt; newLatLngZoom
替换
CameraPosition cameraPosition = new CameraPosition.Builder().target(location).zoom(12).build();
googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
带
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(location, 9));
在CancelableCallback中使用animateCamera（解决方法）
googleMap.animateCamera(CameraUpdateFactory.newLatLngBounds(latLngBounds, 5), new GoogleMap.CancelableCallback() {
@Override
public void onFinish() {
CameraUpdate zout = CameraUpdateFactory.zoomBy(-3f);
googleMap.animateCamera(zout);
}
@Override
public void onCancel() {
}
});
