Android - 视图切换器

Question

我想动态添加视图切换器。

ViewSwitcher switcher = new ViewSwitcher(this); 

如何将两个布局添加到视图切换器并使用代码切换视图？

错误：

Answer 1

公共方法

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

将带有指定布局参数子视图。

Answer 2

请参阅ViewSwitcher的Android documentation。您可以根据需要使用addView()和showNext()方法。

呼叫addView两次指数在0和1

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

这应该没有问题工作..
