Answer 1

use the setContentView on your onclicklistener method Like :

setContentView(R.layout.layout);

EDIT: I think you want when btnRotateit is press then you want to display relChild1 and relChild2 and again press btnRotateBack then appear the mContainer, Then Try like:

Add the code on the btnRotateit onclick Method :

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

and Add the code on the btnRotateBack onclick Method :

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

Try this one and Let me know.

Answer 2

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:

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

Answer 3

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

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

and in onClick apply rotation and change visibility of components

Answer 4

check this code

 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);
   }
});
