在BaseActivity中加入以下代码

/** * 申请运行时权限 * * @param permissions 权限数组 * @param listener 回调监听 */
        public static void requestRuntimePermission(String[] permissions, PermissionListener listener) {
            Activity topActivity = ActivityCollector.getTopActivity();
            if (null == topActivity) {
                return;
            }
            mListener = listener;
            List<String> requestPermissions = new ArrayList<>();
            for (String permission : permissions) {
                if (ContextCompat.checkSelfPermission(topActivity, permission) != PackageManager.PERMISSION_GRANTED) {
                    requestPermissions.add(permission);
                }
            }
            if (!requestPermissions.isEmpty()) {
                ActivityCompat.requestPermissions(topActivity, requestPermissions.toArray(new String[requestPermissions.size()]), 1);
            } else {
                mListener.onGranted();
            }
        }
    
        /** * 运行时权限回调重写 */
        @Override
        public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
            if (grantResults.length > 0) {
                List<String> deniedPermissions = new ArrayList<>();
                for (int i = 0; i < grantResults.length; i++) {
                    int grantResult = grantResults[i];
                    String permission = permissions[i];
                    if (grantResult != PackageManager.PERMISSION_GRANTED) {
                        deniedPermissions.add(permission);
                    }
                }
                if (!deniedPermissions.isEmpty()) {
                    mListener.Denied(deniedPermissions);
                } else {
                    mListener.onGranted();
                }
            }
        }

使用方法：  
继承BaseActivity后这样申请权限

//申请多组权限
    requestRuntimePermission(new String[]{Manifest.permission.CAMERA, Manifest.permission.CALL_PHONE}, new PermissionListener() {
                        @Override
                        public void onGranted() {
                            Toasters("允許");
                        }
    
                        @Override
                        public void Denied(List<String> deniedPermissions) {
                            Toasters("拒絕" + deniedPermissions.get(0));
                        }
                    });
