我正在使用MapVIew，该错误永远不会让我执行该应用程序。我一直在考虑解决方案几个小时，但无法解决此问题。我调查了类似的问题，但没有一个给我答案。我正在寻找此问题的解决方案。我在底部张贴了代码，错误消息和XML布局代码。
public class Mainactivity extends FragmentActivity implements OnMapReadyCallback {
private static final int LOCATION_REQUEST_CODE = 101;
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mainactivity);
}
private void requestPermission(String permissionType,int requestCode ){
ActivityCompat.requestPermissions(this,new String[]{permissionType},requestCode);
}
public void onRequestPermissionResult(int requestCode,String permissions[],int[]grantResults){
switch (requestCode){
case LOCATION_REQUEST_CODE: {
if (grantResults.length == 0 || grantResults[0] != PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "Unable to show current location. You need to give us permission!", Toast.LENGTH_LONG).show();
} else {
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.mapView2);
mapFragment.getMapAsync(this);
}
}
}
}
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
if(mMap != null) {
int permission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
if(permission == PackageManager.PERMISSION_GRANTED){
mMap.setMyLocationEnabled(true); }else{
requestPermission(
Manifest.permission.ACCESS_FINE_LOCATION,LOCATION_REQUEST_CODE);
}}
LatLng newOlympic = new LatLng(35.67946180000001, 139.71424260000003);
Marker newOlympic1 = mMap.addMarker(new MarkerOptions()
.position(newOlympic)
.title("newOlympic")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.photo_yoyogi_national_stadium)));
mMap.moveCamera(CameraUpdateFactory.newLatLng(newOlympic));
}}
错误代码如下。
