use the setContentViewon your onclicklistener method Like :

setContentView在您的 onclicklistener 方法上使用 ，例如：

setContentView(R.layout.layout);

EDIT:I think you want when btnRotateitis press then you want to display relChild1and relChild2and again press btnRotateBackthen appear the mContainer, Then Try like:

编辑：我想你想的时候btnRotateit是按那么你想显示relChild1和relChild2并再次按下btnRotateBack再出现mContainer，然后再尝试使用：

Add the code on the btnRotateitonclick Method :

在btnRotateitonclick 方法上添加代码：

relChild1.setVisibility(View.VISIBLE);
relChild2.setVisibility(View.VISIBLE);
mContainer.setVisibility(View.GONE);

and Add the code on the btnRotateBackonclick Method :

并在btnRotateBackonclick 方法上添加代码：

relChild1.setVisibility(View.GONE);
relChild2.setVisibility(View.GONE);
mContainer.setVisibility(View.VISIBLE);

Try this one and Let me know.

试试这个，让我知道。

From your response to vishwa, it looks like you don't want to change the layout of your existing activity so much as to change to another activity. In which chase:

从您对 vishwa 的回应来看，您似乎不想更改现有活动的布局，而是要更改为另一个活动。在哪个追逐中：

Intent intent = new Intent(this, secondpage.class);
startActivity(intent);

onClick(View v)
{
    setContentView(R.layout.another);
                            ^^^^^^^ 
}

EDIT :For example you have two view, you can set visibility INVISIBLEor GONE

编辑：例如您有两个视图，您可以设置可见性INVISIBLE或GONE

and in onClick apply rotation and change visibility of components

并在 onClick 应用旋转并更改组件的可见性

check this code

检查此代码

 private View view = null ;
 Button addbutton = null;
 ViewGroup parent = null;
 LayoutInflater inflater = null;

 inflater= (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
 addbutton = (Button)findViewById(R.id.btnAdd);

 parent = (ViewGroup) findViewById(R.id.mainxml);


 addbutton.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View view) {
        view = inflater.inflate(R.layout.other, null);
        parent.addView(view);
   }
});
