Question

I have a ViewPager in my main Activity and make a TextView on every page.

@Override
    public Object instantiateItem(View collection, int counterID) {
        TextView counter = new TextView(cxt);
        ((ViewPager) collection).addView(counter, 0);
        return counter;
    }

TextView shows counter value and I want to change it on active page (TextView text) using the method I implemented in the same Activity with PagerAdapter.

Is there any way to access TextView on specific page outside of PagerAdapter (in the same Activity) and change its attributes?

Answer 1

You can set an ID to the TextView by calling

textview.setId(int id);

Then you can find your view by (TextView) findViewById(int id)

or you can set a Tag on the textview:

textview.setId(Object tag); and find the view via (TextView) findViewWithTag (Object tag)
