@Override
 public View onCreateView(LayoutInflater inflater, final ViewGroup container, Bundle 
 savedInstanceState) {

    View view = inflater.inflate(R.layout.fragment_msg, container, false);
    Button updateBtn = (Button) view.findViewById(R.id.updateB);
    updateBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Log.e("buttonClick", "button");
            update();
        }
    });

    return view;
}

Answer 1

更改此行：

transaction.add(R.id.fragment_msg, loading, "test");

到

transaction.replace(R.id.fragment_msg, loading, "test");

Answer 2

您希望在单击按钮时替换片段，但您在代码中执行的操作是使用以下代码行添加片段：

transaction.add(R.id.fragment_msg, loading, "test");

将此行更改为：

transaction.replace(R.id.fragment_msg, loading, "test"); which does what you want.
