if ("com.jxw.online_study".equals(packageInfo.packageName)) { if (mAppPermissions.getPermissionGroups().isEmpty()) { return; } for (AppPermissionGroup group : mAppPermissions.getPermissionGroups()) { String[] permissionsToGrant = null; final int permissionCount = group.getPermissions().size(); for (int j = 0; j < permissionCount; j++) { final Permission permission = group.getPermissions().get(j); permissionsToGrant = ArrayUtils.appendString( permissionsToGrant, permission.getName()); } if (permissionsToGrant != null) { group.grantRuntimePermissions(true, false, permissionsToGrant); } } confirmPermissionsReview(); executeCallback(true); activity.finishAfterTransition(); }优化这段代码，添加多个包名

可以将这段代码封装成一个方法，传入包名和权限组列表参数，然后在调用时传入多个包名和对应的权限组列表即可。

代码示例：

private void grantRuntimePermissions(String packageName, List<AppPermissionGroup> permissionGroups) {
    if (TextUtils.isEmpty(packageName) || permissionGroups == null || permissionGroups.isEmpty()) {
        return;
    }
    for (AppPermissionGroup group : permissionGroups) {
        String[] permissionsToGrant = null;
        final int permissionCount = group.getPermissions().size();
        for (int j = 0; j < permissionCount; j++) {
            final Permission permission = group.getPermissions().get(j);
            permissionsToGrant = ArrayUtils.appendString(permissionsToGrant, permission.getName());
        }
        if (permissionsToGrant != null) {
            group.grantRuntimePermissions(true, false, permissionsToGrant);
        }
    }
    confirmPermissionsReview();
    executeCallback(true);
    activity.finishAfterTransition();
}

调用示例：

grantRuntimePermissions("com.jxw.online_study", permissionGroups1);
grantRuntimePermissions("com.example.app1", permissionGroups2);
grantRuntimePermissions("com.example.app2", permissionGroups3);
