Question

I would like to launch new activity under instantiateItem() Function. What i understand about this function is that it is just allowed to add TextView under this function itself. Is is possible to create new activity or intent below the function ? Codes are described as below.

@Override
public Object instantiateItem(View container, int position) {

    RelativeLayout v = new RelativeLayout(mContext);

    TextView t = new TextView(mContext);
    t.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
            LayoutParams.FILL_PARENT));
    t.setText(mData[position]);
    t.setTextSize(30);
    t.setGravity(Gravity.CENTER);

    v.addView(t);

    ((ViewPager) container).addView(v, 0);

    return v;

}

If you want diffrent layout for each page then you can do something like this, in instantiateItem

View parent_view = null;

        if (position == 0) {
            parent_view = getViewForPageOne();

        } else if (position == 1) {
            parent_view = getViewForPageTwo();

        .........

        ((ViewPager) collection).addView(parent_view, 0);
        return parent_view;

    }

and

private View getViewForPageOne(){
        View v = getLayoutInflater().inflate(R.layout.layout_page_one, null);
         TextView whatText =(TextView) v.findViewById(R.id.idOfTextView);
         whatText.setText("Page One");
         ....
         ....

         return v;
    }
