我正在android工作室开发我的第一个应用程序,它使用google地图。我正在尝试检查MapsActivity中的权限,但我正在获取“无法解析符号”访问位置。
我不知道为什么会这样,我有点力不从心。
下面是mapsActivity.java:
package com.example.i329968.mapstests;
import android.content.pm.PackageManager;
import android.support.v4.app.ActivityCompat;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import android.support.v4.content.ContextCompat;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback
{
private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// 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;
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
googleMap.setIndoorEnabled(true);
// Add a marker in Sydney and move the camera
LatLng sydney = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
// mMap.setMyLocationEnabled(true);
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED)
{
mMap.setMyLocationEnabled(true);
}
else
{
// Show rationale and request permission.
}
}
}
在androidmanifest.xml中,我有:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
提前谢谢。
最佳答案
添加到代码中:
import android.Manifest;
