Android XML OnClick属性对setContent更改无效

我尝试在一个活动中多次使用set content实现多个布局，并用它再次初始化所有小部件，到目前为止我成功了，但有一点我被卡住了

setContentView（R.layout.layout1）

-->

initWidgets1（）-->
btn1.setOnClickListner（）
-->

setContentView（R.layout.layout2）

-->

initWidgets2（）-->
btn2.setOnClickListner（）
-->

但是

此方法也不适用于任何布局

虽然

btn.setOnClickListner（）

可以工作，但它需要巨大的内存来存储巨大的列表，如果它可以工作的话，后者就很容易了

代码：

尝试使用多个活动或片段。大多数人不会做你想做的事情。

应该使用片段。我正在使用选项卡栏活动，并尝试仅在一个选项卡中显示多个布局。我是Android新手，。。

handleClick2(View v)
{
Switch (v.getId())
{-------------
---------
Multiple click handles
-----
---
}

Similarly.
handleClick1(View v)
{
Switch (v.getId())
{
-----------
---------
Multiple click handles
-----
---
}
