所以我試圖在谷歌地圖片段上覆寫 KML 檔案但沒有成功（不幸的是，檔案對我沒有幫助https://developers.google.com/maps/documentation/android-sdk/utility/kml）我嘗試了解決方案從其他沒有運氣的答案..
我的代碼如下（根據檔案實作，至少我認為..我是 Android 開發新手，所以我可能錯了）：
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
private ActivityMapsBinding binding;
KmlLayer layer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityMapsBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
try {
KmlLayer layer = new KmlLayer(mMap, R.raw.mykmlfile, getApplicationContext());
layer.addLayerToMap();
} catch (XmlPullParserException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
}
}
uj5u.com熱心網友回復：
您在尚未啟動addLayerToMap時呼叫...您應該呼叫它mMaponMapReady
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
try {
KmlLayer layer = new KmlLayer(googleMap, R.raw.mykmlfile, getApplicationContext());
layer.addLayerToMap();
} catch (Exception e) {
e.printStackTrace();
}
}
