I recently started to write an application which let me to get information from a forum. I used JSoup library for scraping the data. My first part is going well.
When the app opens, it just gets data from the site(sub-forum names) and pass it so the listview is able to show them. When I press an item in the listview it just gets the thread list in the sub-forum. All the things are working properly excepts the listview doesn't get updated correctly.
As you can see when I press an item from the list(Just the first item in the list) then it set loadedSub to true then it gets the thread list using an async-task then in the postexecute it calls notifyDataSetChanged() on PagerAdapter. The problem is it just updates the UI perfectly, even leaving 1 tab only as I wanted, but the problem is that threadList doesn't appear in the listview. It only shows me the listview with previous data, not the threadlist.
Should I use another activity or is there something I am missing?

Alright, I got it solved using FragmentStatePageAdapter instead of using FragmentPageAdapter

I have buttons within the rows of a recyclerview within a fragment within an activity. When the user clicks one of the buttons, I want to switch to a different activity. How do I establish context for the Intent to switch to the new activity.
OR, should I move the onClickListener back to the fragment or activity (is it incorrect to place onClickListener within the recyclerview adapter code). If so, how do I obtain reference to the button clicked from outside the recyclerview adapter.

So in NameList where it says "fragmentTransaction.add(android.R.id.content, fragment2, "login").commit();" I need to find the container of NameList when I try R.id.container a blank white screen appears. What should I put instead of android.R.id.content in this case?

What should the container?
You can simply use a FrameLayout as the container layout and add fragments dynamically.
I am new at android development and just trying to learn along the way!
I am creating an android app that I would like to show different views, one for weight, weather, and hydration (are what I have called them for now). Although when I run my app I only get my one view displayed.

An once I run it I just get three screens that look like this...
Inside your public Fragment getItem(int position) {
which is inside your
public class SectionsPagerAdapter extends FragmentPagerAdapter {
Implement this:
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new fragment1();
case 1:
return new fragment2();
case 2:
return new fragment3();
default:
// this should never happen
return null;
//return new Fragment();
}
}
Where "fragment1-2 and 3" are the name of the java classes you've defined to run there.
I use my "getItem" exactly this way, with nothing more inside it. So I don't know if you have to maintain your return PlaceholderFragment.weight(position + 1); there. Try commenting it out and see what happens. I don't use createview either. Best.
The problem is here
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View hydration = inflater.inflate(R.layout.hydration, container, false);
return hydration;
}
You are always inflating the hydration layout, in every fragment
in my NavigationDrawerFragment.java
i have this code
expListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
#Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
String header = listDataHeader.get(groupPosition);
Category child = listDataChild.get(header).get(childPosition);
// child.name to get the name
// child.id to get the id
//Toast.makeText(getActivity(),"ChildNme: "+child.name+" ChildId: "+child.id, Toast.LENGTH_SHORT).show();
selectItem(1);
return false;
}
});
after i click the child, i set selectItem to 1
the selectItem(1) will go to MainActivity.java
public void onNavigationDrawerItemSelected(int position) {
// update the main content by replacing fragments
FragmentManager fragmentManager = getFragmentManager();
// NEW STUFF
if(position == 1){
fragmentManager.beginTransaction()
.replace(R.id.container, CategoryFragment.newInstance())
.commit();
}
}
my question is how to pass the child.name and child.id from NavigationDrawerFragment.java to MainActivity.java then pass to CategoryFragment?
or any other solution to pass the child.name and child.id to CategoryFragment.

update your selectitem() and onNavigationDrawerItemSelected methods to accept two more arguments i.e child.id and child.name
private void selectItem(int position,String id,String name) {
mCurrentSelectedPosition = position;
if (mDrawerListView != null) {
mDrawerListView.setItemChecked(position, true);
}
if (mDrawerLayout != null) {
mDrawerLayout.closeDrawer(mFragmentContainerView);
}
if (mCallbacks != null) {
mCallbacks.onNavigationDrawerItemSelected(position,id,name);
}
}
pass child.id and child.name in selectItem() method so which in turn will call onNavigationDrawerItemSelected() method implemented in MainActivity.
Now in MainActivity, pass the values to the fragment using Bundle
here
fragmentManager.beginTransaction()
.replace(R.id.container, CategoryFragment.newInstance(id,name))
.commit();
you will also need to update to CategoryFragment.newInstance(String,String) to accept the arguments
Updating code to 'setText' in 'edittext'
In your 'CategoryFragment' 'newInstance' method pass data in bundle like below
CategoryFragment categoryfragment = new CategoryFragment()
Bundle bundle = new Bundle()
bundle.putStringExtra("id",id)
bundle.putStringExtra("name",name)
categoryfragment.setArguements(bundle)
return categoryfragment
Now in onCreateView of Categoryfragment get this data like below
if(getArguments().getExtras != null) {
String catid = getArguments.getStringExtra("id");
String catname = getArguments.getStringExtra("name");
yourEditText.setText(catname);
}

myView.setScaleType(ImageView.ScaleType.FIT_CENTER);

}
*EDIT*
Changing this line:
ImageView myView = new ImageView(Logger.this.getActivity().getApplicationContext());
to this:
ImageView myView = new ImageView((Logger)getActivity().getApplicationContext());
solved the problem, but that was not what I was looking for. Thanks to Kapil Vij for correct Answer!
Do this
ImageView myView = new ImageView(getActivity());
getActivity() method is accessible in fragment class, and u r trying to access it using FragmentActivity class instance.
change to:
Logger.this.getApplicationContext()
Logger it-self is activity you call getActivity to get the reference of the activity inside a Fragment
EDIT
Saw that you are calling it inside a fragment change you code to:
ImageView myView = new ImageView(KayitFragment.this.getActivity().getApplicationContext());
