Android wear : update card textview at runtime in FragmentGridPagerAdapter - wear-os

Question

I'd like to be able to update the value of a TextView in a fragment created using the FragmentGridPagerAdapter class, but I haven't really an idea of how I could achieve that.
Here is where I call my class to create the fragments.
final GridViewPager pager = (GridViewPager) findViewById(R.id.pager);
pager.setAdapter(new SGridPagerAdapter(this, getFragmentManager(), data));
DotsPageIndicator dotsPageIndicator = (DotsPageIndicator) findViewById(R.id.page_indicator);
dotsPageIndicator.setPager(pager);
And here is my class that extends the FragmentGridPagerAdapter.
public class SGridPagerAdapter extends FragmentGridPagerAdapter {
String[] mData;
private final Context mContext;
private static final String TAG = SGridPagerAdapter.class.getSimpleName();
public SGridPagerAdapter(Context ctx, FragmentManager fm, String[] data) {
super(fm);
mData = data;
mContext = ctx;
}
#Override
public Fragment getFragment(int row, int column) {
Log.d(TAG, "row : " + row + "/columns : " + column);
Fragment f = null;
switch(column) {
case 0 :
f = cardFragment(R.string.welcome_title, R.string.welcome_text);
break;
case 1 :
f = SelectionFragment.newInstance("secondFragment");
break;
}
return f;
}
private Fragment cardFragment(int titleRes, int textRes) {
Resources res = mContext.getResources();
CardFragment fragment = CardFragment.create(res.getText(titleRes), res.getText(textRes));
// Add some extra bottom margin to leave room for the page indicator
//fragment.setCardMarginBottom(
// res.getDimensionPixelSize(R.dimen.card_margin_bottom));
return fragment;
}
#Override
public int getRowCount() {
return 1;//mData.length;
}
#Override
public int getColumnCount(int row) {
return mData.length;
}
}
