java - 将 LinearLayout 的方向作为参数发送给方法 - java Android Studio

Question

我正在尝试创建一种方法，将新的 LinearLayout 添加到现有的 LinearLayout 中。我想向此方法发送一个参数，告诉它新的 LinearLayout 应该是垂直的还是水平的。这是我到目前为止所拥有的，但“LinearLayout.Orientation”不是此参数类型的正确名称。

private LinearLayout addLinearLayout(View linearLayout, LinearLayout.Orientation orientation)
{
    //Create new horizontal linear layout and add to the specified linear layout
    LinearLayout newLinearLayout = new LinearLayout(context);
    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
    layoutParams.setMargins(20, 10, 0, 10);
    newLinearLayout.setOrientation(LinearLayout.orientation);
    ((LinearLayout) linearLayout).addView(newLinearLayout, layoutParams);
    return newLinearLayout;
}

这可能吗？如果是这样，我试图传递的参数的类型是什么？ 感谢您的帮助。

来自the documentation :

public void setOrientation (int orientation)

(...)

orientation Pass HORIZONTAL or VERTICAL. Default value is HORIZONTAL.

private LinearLayout addLinearLayout(LinearLayout linearLayout, int orientation) {
    //Create new horizontal linear layout and add to the specified linear layout
    LinearLayout newLinearLayout = new LinearLayout(context);
    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
    layoutParams.setMargins(20, 10, 0, 10);
    newLinearLayout.setOrientation(orientation);
    linearLayout.addView(newLinearLayout, layoutParams);
    return newLinearLayout;
}

像这样调用这个方法:

addLinearLayout(yourLinearlayout, LinearLayout.HORIZONTAL);
