android what to use instead of onRestart() in a fragment

Question

I'm dealing with .setVisibility() of a view , inside my main fragment at app start. So what I want is that the view is invisible on app start (for this i set INVISIBLE inside onCreateView) and to be visible when I come back to my fragment from other activities while the app is open (and for this I tried to use onRestart() to set view VISIBLE but it cannot resolve onRestart method) is onRestart deprecated or? thanks

EDIT: for all the answers below suggesting to use an onResume (and whom gave a -1), onResume doesn't work as onRestart at all, cause is being called right after onCreateView.

Answer 1

Fragments don't have onRestart() . It's only for Activities.

See the lifecycle of fragments below

I suppose you're looking for onResume() instead

Use a boolean flag to check whether or not you're returning to the Fragment:

private boolean firstVisit;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
    //other stuff
    firstVisit = true;
}

@Override
public void onResume() {
    //other stuff
    if (firstVisit) {
        //do stuff for first visit only

        firstVisit = false;
    }
}

如果要在返回片段时加载内容，则可以使用onStart()或onResume() 。

Answer 3

You can use onRestart() on the activity, making it call whatever method you want on the fragment by making use of getFragmentManager().findFragmentById(R.id.your_fragment) . When a fragment gets restarted its underlying activity got restarted so its onRestart() method was called.

Answer 4

如果您想检测片段何时再次可见，则需要使用onResume()回调方法。

Answer 5

Fragment life cycle doesn't have onRestart() method. You could use onPause() and onResume() as per your requirement.
