Question

我想动态添加视图切换器。

  ViewSwitcher switcher = new ViewSwitcher(this);

如何将我的两个布局添加到视图切换器并使用代码在视图之间切换？

错误：

Answer 1

http://developer.android.com/reference/android/widget/ViewSwitcher.html

公共方法

void     addView(View child, int index, ViewGroup.LayoutParams params)

添加具有指定布局参数的子视图。

Answer 2

参考ViewSwitcher的{{3}}。您可以根据需要使用addView()和showNext()方法。

使用索引0和1调用addView两次。

addView(child, index, 
           new ViewGroup.LayoutParams(
                     LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));

这应该没有问题..
