pass value from activity to fragment using bundle in tabbed activity

Question

I am a java-illiterate, and still trying to develop a app for my personal use. I have started with android-studio\'s \"Tabbed-Activity\", and mostly unaltered except a fragment

Answer 1

In your MainActivity, your sunFragment is unused. Remove this part:

/*Bundle bundle = new Bundle();
bundle.putDouble("loclat", 25.4358);
bundle.putDouble("loclang",81.8463);
Fragment SunFragment = new SunFragment();
SunFragment.setArguments(bundle);*/

You have to set bundle to fragment inside your SectionsPagerAdapter

case 0:
    Bundle bundle = new Bundle();
    bundle.putDouble("loclat", 25.4358);
    bundle.putDouble("loclang",81.8463);

    Fragment sunFragment = new SunFragment();
    sunFragment.setArguments(bundle);

    return sunFragment;

But if you need to set the bundle to fragment from MainActivity. Then use a callback in that purpose.
