我正在開發一個應用程序，我想獲取用戶設備的經緯度。我發現我需要Access_Fine_Location權限以及Access_Coarse_Location，我知道我應該問他們在運行時以及將它們包含在我的AndroidManifest.xml中，但該應用程序只會要求我提供權限ACCESS_COARSE_LOCATION，並且會忽略有關ACCESS_FINE_LOCATION的問題。 這裏是我的代碼Android：在運行時獲取設備位置
private boolean checkAndRequestPermissions(){
int permissionReadContacts = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS);
int locationPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION);
int locationPermission2 =ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
List<String> listPermissionsNeeded = new ArrayList<String>();
if (locationPermission != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.ACCESS_COARSE_LOCATION);
}
if (locationPermission2 != PackageManager.PERMISSION_GRANTED) {
Log.i("addingPerm","addingPerm");
listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
}
if (permissionReadContacts != PackageManager.PERMISSION_GRANTED) {
listPermissionsNeeded.add(Manifest.permission.READ_CONTACTS);
}
if (!listPermissionsNeeded.isEmpty()) {
ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
return false;
}
return true;
}
和這裏的回調：
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
String TAG = "sonder.SplashActivity";
Log.d(TAG, "Permission callback called-------");
switch (requestCode) {
case REQUEST_ID_MULTIPLE_PERMISSIONS: {
Map<String, Integer> perms = new HashMap<String, Integer>();
// Initialize the map with both permissions
perms.put(Manifest.permission.ACCESS_COARSE_LOCATION, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
perms.put(Manifest.permission.READ_CONTACTS, PackageManager.PERMISSION_GRANTED);
// Fill with actual results from user
if (grantResults.length > 0) {
for (int i = 0; i < permissions.length; i++)
perms.put(permissions[i], grantResults[i]);
// Check for both permissions
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new LocListener();
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5000, 10, locationListener);
UserData.setLocation(LocListener.getLat() + "," + LocListener.getLon());
Log.i("aaaaaaaaaa", "aaaaaaaaaa");
Log.i("" + LocListener.getLat(), "" + LocListener.getLon());
if (perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
Log.i("Ahmed", "Ahmed");
Log.d("Permissions", "location services permission granted");
FacebookSdk.sdkInitialize(getApplicationContext());
Thread myThread = new Thread() {
@Override
public void run() {
try {
Log.i("May", "May");
sleep(300);
Intent intent = new Intent(getApplicationContext(), setup_activity.class);
startActivity(intent);
finish();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
};
myThread.start();
} else {
//If permissions are denied
Log.d(TAG, "Location permission not granted ask again");
Intent intent = new Intent(getApplicationContext(), setup_activity.class);
startActivity(intent);
finish();
}
}
}
}
}
}
而且這裏是我的AndroidManifest.xml
