如何访问片段中activity_main.xml的线性布局

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.activity_main, container, false);
    // 其他操作
    return view;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.activity_main, container, false);
    
    LinearLayout linearLayout = view.findViewById(R.id.linear_layout);
    // 其他操作
    
    return view;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.activity_main, container, false);
    
    LinearLayout linearLayout = view.findViewById(R.id.linear_layout);
    
    // 添加子视图
    TextView textView = new TextView(getActivity());
    textView.setText("Hello, World!");
    linearLayout.addView(textView);
    
    // 设置布局参数
    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.WRAP_CONTENT);
    linearLayout.setLayoutParams(layoutParams);
    
    return view;
}
