Question

我正在尝试使用设备中的弹出窗口激活设备上的位置，而无需进入设置页面;我在堆栈溢出上尝试了多种解决方案，但似乎没有一种解决方案可以打开我的模拟器或设备位置我的位置代码如下：

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);
        }


    }


}

主要：

  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

在您的主要课程中修改：

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）删除与运行时权限相关的代码，并尝试在Marshmallow之前发布任何Android版本的设备上运行应用程序。通过这种方式，您将了解问题是否与运行时权限相关

2）您可以尝试使用此库来实现运行时权限。它非常简单易用。 https://github.com/Karumi/Dexter
