模拟器位置

Question

我试图使用设备中的弹出窗口激活设备上的位置，而无需转到"设置"页面；我在堆栈溢出上尝试了多个解决方案，但是似乎没有任何解决模拟器或设备位置的解决方案。
我的位置代码如下：

onrequest：

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull 
String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
        if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED){
          permission. its an array becayse it can be multiple permissions

            locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0 , 0, locationListener);
        }

    }

}

主：

  locationManager =  (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

    locationListener = new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            Log.i("location",""+location.toString());
        }
        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {
        }
        @Override
        public void onProviderEnabled(String provider) {
        }
        @Override
        public void onProviderDisabled(String provider) {
        }
    };
if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED){
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION} ,1);

}else{
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0 , 0, locationListener);
}

清单：

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

构建gradle：

compile 'com.android.support:support-v4:25.0.0'
compile 'com.google.android.gms:play-services-maps:10.2.4'
compile 'com.google.android.gms:play-services-location:10.2.4'

Answer 1

在您的主类中修改以下内容：

if(ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION} ,1);
return;
}else{
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0 , 0, locationListener);
}

1）删除与运行时间权限相关的代码，然后尝试在棉花糖之前发布任何Android版本的设备上运行该应用程序。这样，您将知道问题是否与运行时间许可有关

2）您可以尝试此库来实现运行时间权限。它非常简单易用。https://github.com/karumi/dexter
