Question

I have a fragment with 4 tabs, in one tab i need to show a listview. I have got this far on my code but have a couple errors and i’m not sure if i’m just not doing it right or if i’m missing something simple. Here is my code that i’m using

fragment activity

public class SupportFragment extends SherlockFragment{
String[] supporters = new String[] {
        "Gulf Shores",
        "Central",
        "Spanish Fort",
        "Jackson Heights",
        "Summerdale",
        "Atlas",
        "Robertsdale",
        "Eastern Shore"
};

int[] images = new int[] {
        R.drawable.gulfshores,
        R.drawable.central,
        R.drawable.spanishfort,
        R.drawable.jacksonheights,
        R.drawable.summerdale,
        R.drawable.atlas,
        R.drawable.robertsdale,
        R.drawable.easternshore
};

String[] church = new String[]{
        "Chruch of Christ",
        "Chruch of Christ",
        "Chruch of Christ",
        "Chruch of Christ",
        "Chruch of Christ",
        "Chruch of Christ",
        "Chruch of Christ",
        "Chruch of Christ"
};


 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {

     ViewGroup root = (ViewGroup) inflater.inflate(R.layout.tab_support_layout, null);


     List<HashMap<String,String>> aList = new ArrayList<HashMap<String,String>>();

        for(int i=0;i<10;i++){
            HashMap<String, String> hm = new HashMap<String,String>();
            hm.put("sup", "Supporters : " + supporters[i]);
            hm.put("chur","Church : " + church[i]);
            hm.put("icon", Integer.toString(images[i]) );
            aList.add(hm);
        }

        String[] from = {"sup", "chur", "icon"};

        int[] to = {R.id.icon, R.id.sup, R.id.chur};

        SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.listview_layout, from, to);

        ListView listView = (ListView) findViewById(R.id.listview);

        listView.setAdapter(adapter);


        return root;

 }



 }

I am getting an error on these two lines of code from this

SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.listview_layout, from, to);

and

 ListView listView = (ListView) findViewById(R.id.listview);

the error i’m getting is:

The method getBaseContext() is undefined for the type SupportFragment

The method findViewById(int) is undefined for the type SupportFragment

xml for listview

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@drawable/tableback" >

<TextView
    android:id="@+id/textview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
/>

<ListView
    android:id="@+id/listview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
/>
</LinearLayout>

and the listview layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">

<ImageView
    android:id="@+id/icon"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingTop="10dp"
    android:paddingRight="10dp"
    android:paddingBottom="10dp"
/>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
>
    <TextView
        android:id="@+id/sup"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="15dp"
    />

    <TextView
        android:id="@+id/chur"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="10dp"
    />
</LinearLayout>
</LinearLayout>

any help you can give is greatly appreciated

Answer 1

You do not have a FragmentActivity you have a Fragment, so of course you can’t get the Context with getBaseContext(), you have to use getActivity() instead.
You also have to inflate a View to use findViewById, if you want to do that in a Fragment. However if you want to use Tabs you need a FragmentActivity which hadels your Fragments.

You can inflate a View like this in your fragments onCreateView() method:

View view = inflater.inflate(R.layout.myLayout, null);

Then you can call findViewById like this:

[...]view.findViewById(...);
