Hi sowmya,
You can get the value of the first view textbox by,
this.getView('view1Name').byId('view1textBoxID').getText();
Assign the value to your Second View's text box in the onInit() method of view 2 controller.
this.getView().byId('view2textBoxID').setText( this.getView('view1Name').byId('view1textBoxID').getText() );
