Android -视图切换器

Question

我想动态添加一个视图切换器。

  ViewSwitcher switcher = new ViewSwitcher(this);

我如何添加我的两个布局到视图切换器和视图之间使用代码切换?

错误:

Answer 1

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Android文档。您可以根据需要使用addView()和showNext()方法。

两次调用索引为0和1的addView

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