如何在Android上动态添加LinearLayout？

// 找到父级布局视图
LinearLayout parentLayout = findViewById(R.id.parent_layout);

// 创建一个新的LinearLayout对象
LinearLayout childLayout = new LinearLayout(this);

// 设置LinearLayout的布局参数
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
    LinearLayout.LayoutParams.MATCH_PARENT,
    LinearLayout.LayoutParams.WRAP_CONTENT
);
childLayout.setLayoutParams(layoutParams);

// 可选地，设置LinearLayout的背景颜色
childLayout.setBackgroundColor(Color.parseColor("#FFFFFF"));

// 将LinearLayout添加到父级布局中
parentLayout.addView(childLayout);
