Android6.0之后运行时权限，定位不执行回调方法

• 网络定位权限为Manifest.permission.ACCESS_COARSE_LOCATION

在Activity中检查

if (Build.VERSION.SDK_INT >= 23) {
int checkPermission = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION);
        if (checkPermission != PackageManager.PERMISSION_GRANTED) {
//没有获取权限，发起申请
          ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
            
        } else {
           //doing everything what you want
        }
}

在Activity中重写以下方法

 @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        if (requestCode == 1) {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
               //发起定位
                initLocation();
            } else {
                ToastUtils.showShortToast("您拒绝了定位权限");
            }
        }
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }

在Fragment中检查权限

• fragmetn中发起权限申请与Activity操作有一点不同，不过也不容忽视，若是不小心手一抖写错了方法，是不会执行回调方法的........

if (Build.VERSION.SDK_INT >= 23) {
int checkPermission = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION);
        if (checkPermission != PackageManager.PERMISSION_GRANTED) {
          //没有获取权限，发起申请，不同之处
           requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
            
        } else {
           //doing everything what you want
        }
}

• 在fragment中重写onRequestPermissionsResult()方法，和Activity中做法一致

 @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        if (requestCode == 1) {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
             //发起定位
                initLocation();
            } else {
                ToastUtils.showShortToast("您拒绝了定位权限");
            }
        }
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
