如何在Android中禁用/启用LinearLayout上的所有子项

private void setLinearLayoutChildrenEnabled(ViewGroup viewGroup, boolean enabled) {
    for (int i = 0; i< viewGroup.getChildCount(); i++) {
        View childView = viewGroup.getChildAt(i);
        if (childView instanceof ViewGroup) {
            setLinearLayoutChildrenEnabled((ViewGroup) childView, enabled);
        } else {
            childView.setEnabled(enabled);
        }
    }
}

LinearLayout linearLayout = findViewById(R.id.your_linear_layout);
setLinearLayoutChildrenEnabled(linearLayout, false);

LinearLayout linearLayout = findViewById(R.id.your_linear_layout);
setLinearLayoutChildrenEnabled(linearLayout, true);
