Answer 1

Change the pagezero class oncreateview code like this .....

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view =getActivity().getLayoutInflater().inflate(R.layout.componentname,null);
        name=(EditText)view.findViewById(R.id.nameTV);

        name.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                a=name.getText().toString().trim();
                Toast.makeText(getApplicationContext(),a,Toast.LENGTH_SHORT).show();


            }

 return view;
        });

Return the view friend and then use default layout inflater...

Answer 2

At the time you click the edittext field, is there any content? Maybe you should get the text in the lost focus event of the edittext field. Thus you can enter some text first...

Example:

name.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if(hasFocus == false){
                //get text from edittext field...
            }

        }
    });

The way you try to get the text looks right to me. At least I do it the same way.

In the PagerAdapter's 'getItem' Method you should instantiate your fragments directly:

@Override
public Fragment getItem(int position) {     
    switch (position) {
        case 0:
            return new PageZero();
        case 1:
            return new PageOne();
        case 2:
            return new PageTwo();
    }
    return null;
}

The Viewpager only calls getItem if it wants to create a new item. Unfortunatly they called the method getItem and not createItem which would be more obvious.
