动态获取权限

首先申请权限：

 List<String> permissionList = new ArrayList<>();


        /**
         * 允许程序获取网络信息状态，如当前的网络连接是否有效
         * */
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.INTERNET) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.INTERNET);
        }
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.ACCESS_COARSE_LOCATION);
        }
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.ACCESS_FINE_LOCATION);
        }


        if (permissionList.size() != 0) {  //申请的集合不为空时，表示有需要申请的权限
            ActivityCompat.requestPermissions(this, permissionList.toArray(new String[permissionList.size()]), 1);
        } else { //所有的权限都已经授权过了
            findview();
        }

申请权限的回调

 
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case 1:

                if (grantResults.length > 0) { //安全写法，如果小于0，肯定会出错了
                    for (int i = 0; i < grantResults.length; i++) {
                        int grantResult = grantResults[i];
                        if (grantResult == PackageManager.PERMISSION_DENIED) { //这个是权限拒绝
                            String s = permissions[i];
                            Toast.makeText(this, s + "权限被拒绝了", Toast.LENGTH_SHORT).show();
                            initJurisdiction();
                        } else { //授权成功了
                            findview();
                        }
                    }
                }
                break;
            default:
                break;

        }
    }
