Android 多组动态权限申请

示例图：

首先定义需要申请的权限

String[] permissions = new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.CAMERA,Manifest.permission.READ_EXTERNAL_STORAGE};
    List<String> mPermissionList = new ArrayList<>();
    private static final int PERMISSION_REQUEST = 1;

权限申请：

private void initPermission(){
        mPermissionList.clear();
        /**
         * 判断哪些权限未授予
         */
        for (int i = 0; i < permissions.length; i++) {
            if (ContextCompat.checkSelfPermission(this, permissions[i]) != PackageManager.PERMISSION_GRANTED) {
                mPermissionList.add(permissions[i]);
            }
        }
        /**
         * 判断是否为空
         */
        if (mPermissionList.isEmpty()) {//未授予的权限为空，表示都授予了
        } else {//请求权限方法
            String[] permissions = mPermissionList.toArray(new String[mPermissionList.size()]);//将List转为数组
            ActivityCompat.requestPermissions(MainActivity.this, permissions, PERMISSION_REQUEST);
        }
    }
    /**
     * 响应授权
     * 这里不管用户是否拒绝，都进入首页，不再重复申请权限
     */
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case PERMISSION_REQUEST:
                break;
            default:
                break;
        }
    }

在oncreate中调用initPermission()即可。
