无法parsing方法getMap()

我正在尝试获取地图片段,在我的应用程序中工作,并且在尝试获取我的GoogleMap对象时继续出现错误。

FragmentWithMap.java

Fragment mmm = getChildFragmentManager().findFragmentById(R.id.fragment_map2); mMap = ((SupportMapFragment) mmm).getMap(); // Check if we were successful if (mMap != null) { setUpMap(); } } } private void setUpMap() { double lat = LAT; double lng = LON; String name = "You are here"; if (place != null) { lat = place.getLat(); lng = place.getLng(); name = place.getName(); } if (marker != null) { marker.remove(); } LatLng position = new LatLng(lat, lng); MarkerOptions markerOptions = new MarkerOptions(). position(position). title(name). icon(BitmapDescriptorFactory.fromResource(userIcon)). snippet("Your last recorded location"); marker = mMap.addMarker(markerOptions); if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { return; } mMap.setMyLocationEnabled(true); CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(position, 15); mMap.animateCamera(cameraUpdate); } } 

这里是XML

fragment_with_map.xml

 <fragment xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/fragment_map2" tools:context="com.example.eldad.myplacesapp.FragmentWithMap" android:name="com.google.android.gms.maps.SupportMapFragment" /> 

我从不同的应用程序中复制代码,其中方法getMap()仅仅被弃用,所以我怀疑问题是在代码本身。 我没有问题,它被弃用,我不喜欢使用getMapAsync(),如果我不必。 但在这里出于某种原因,我收到了错误

“无法parsing方法”getMap()'“

。 我也收到一个错误

“错误:执行任务失败:app:compileDebugJavaWithJavac”。

编译失败 有关详细信息,请参阅编译器错误输出。

虽然我不能确定它是否与这个问题有关。

getMap()方法先前已被弃用,现在它已被删除。 如果您查看SupportMapFragment的文档 ,则不在此处。

您也可以在发行说明中看到:

之前弃用的getMap()函数在Google Play服务SDK中不再可用。 (它仍然可以在发送到Android设备的Google Play服务APK中使用。)自2014年12月起,getMap()函数已被弃用。请参阅发布博客文章以获取从getMap()转换为getMapAsync()的帮助。

并从博客文章:

在2014年12月,我们不推荐使用getMap()来支持getMapAsync()。 从这个版本开始,你将需要使用getMapAsync()来编译你的应用程序。

所以,只要使用getMapAsync(),很简单。

首先让你的Fragment实现OnMapReadyCallback接口:

 public class FragmentWithMap extends android.support.v4.app.Fragment implements OnMapReadyCallback { 

然后,修改你的setUpMapIfNeeded()代码,并添加onMapReady()callback:

 private void setUpMapIfNeeded() { if (mMap == null) { SupportMapFragment mapFrag = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.fragment_map2); mapFrag.getMapAsync(this); } } @Override public void onMapReady(GoogleMap googleMap) { mMap = googleMap; setUpMap(); } 

用这个

 compile 'com.google.android.gms:play-services-location:8.4.0' map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById( R.id.map)).getMap();
