How to get String Resource within ViewPager Adapter?

Question

I trying to set the title for my viewpager, I can\'t seem to get it to work. I tried Resources.getSystem().getString(R.string.title1); and also tried to pass a context. Coul

Answer 1

With Kotlin I do this by sending context to the adapter, as below:

class FmAdapter(val context: Context, fm: FragmentManager) : FragmentStatePagerAdapter(fm, BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT) {

    private val fragments = arrayListOf()

    init {
        fragments.add(Fragments(R.string.title1, FragmentOne()))
        fragments.add(Fragments(R.string.title2, FragmentTwo()))
    }

    override fun getCount(): Int = fragments.size

    override fun getItem(position: Int): Fragment = fragments[position].fragment

    override fun getPageTitle(position: Int): CharSequence? = context.getString(fragments[position].title)
}

with data class:

data class Fragments(@StringRes val title: Int, val fragment: Fragment)

and simple call from activity, like:

rv.adapter = FmAdapter(this, supportFragmentManager)
