但根据新要求，我们需要动态添加复选框.就像需要从 API 调用中获取选项并将其转换为视图中的复选框.我花了很多时间在里面.有人可以建议一种方法来解决这个问题.
But as per the new requirement we need to add the check boxes dynamically. Like need to fetch the options from the API call and convert it as check boxes in the view. I spent lots of time in it. Can someone suggest a method to solve this.
我们的布局应该是这样的.在列表视图中，我们将显示员工详细信息，并且应从 API 调用或数据库中加载每条员工记录的资格.
Our layout should be like this. In a list view we are displaying employee details and for each employee record the qualification should be loaded from the API call or database.

推荐答案
LinearLayout featuresTable = (LinearLayout) findViewById(R.id.failure_reasonslist);
// use loop
CheckBox feature1 = new CheckBox(this);
featuresTable.addView(feature1 );
