Try this:

return true;
call the method setcontentview() in your oncreate() method...
i guesss its missing from there...
try if it works
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
conListView=getListView();
conListView.setOnItemClickListener(viewConListener);
//like this
setcontentview(R.layout.yourlayout);
String[] from = new String[] { "name" };
int[] to = new int[] { R.id.countryTextView };
conAdapter = new SimpleCursorAdapter(CountryList.this, R.layout.country_list, null, from, to);
setListAdapter(conAdapter); // set adapter

I am trying to use the following code
public int id=GeneralPreferenceFragment.getView().getParent().getId();
inside SettingAvtivity/MainActivity .
but it shows following error
Non-static method 'getView()' can not be referenced from a static Context
please help me resolving this issue
following is the method used
public void method1(View view)
{
Button bt1=(Button)findViewById(R.id.button);
bt1.setOnClickListener(new
View.OnClickListener() {
#Override
public void onClick(View view) {
// ViewGroup vg = (ViewGroup) mCurrentFragment.getView().getParent();
Toast.makeText(SettingsActivity.this,"Sound",Toast.LENGTH_SHORT).show();
DataSyncPreferenceFragment fragment;
GeneralPreferenceFragment fragment1;
GeneralPreferenceFragment frag1;
fragment= new DataSyncPreferenceFragment();
fragment1=new GeneralPreferenceFragment();
GeneralPreferenceFragment prefFragment = new GeneralPreferenceFragment();
int id = prefFragment.getView().getParent().getId();
FragmentManager fm=getFragmentManager();
FragmentTransaction ft=fm.beginTransaction();
ft.replace(R.id.layout_1id,fragment);
ft.remove(fragment1);
ft.add(R.id.layout_1id,fragment);
ft.addToBackStack(null);
ft.commit();
}
});
}
if i use an instance of General preferenceFragment then it shows

You need to call method getView() from instance of you class GeneralPreferenceFragment. I.e:
GeneralPreferenceFragment prefFragment = new GeneralPreferenceFragment();
// ... some business logic
public int id = prefFragment.getView().getParent().getId();
I've got this error, but I don't know how to resolve this error.
Error: Fragments should be static such that they can be re-instantiated by the system, and anonymous classes are not static [ValidFragment]
Please help me if you know how to solve

You are declaring your Fragment as abstract class. Abstract class can't be instantiated. It can be used only as a base class. The way you are trying to use it (anonymous class) is not possible in Android framework. A Fragment class must be a subclass of Fragment (or an existing subclass of it) and concrete.
Remove abstract keyword
public class FoodListFragment extends Fragment {
Things your are trying to achieve with
public abstract void doRefresh();
should be done using an interface.

You need to unbind service:

// your onStop code
if(musicConnection != null) {
unbindService(musicConnection);
}
super.onStop();

In the android app I am creating, I have a scrollable tabs from my TabsPagerAdapter class which extends FragmentPagerAdapter. However, in my app, I am trying to display all user installed apps on the phone into a section of a tab. However the class which was able to return all of that extended FragmentActivity.
I tried to follow this, but it is not working.
How to list all downloaded android apps in a fragment
Sadly, after much research I found out that I can only put fragments in different tabs and only have one Activity displayed at any one time and the tabs themselves can only return Fragments.
I really need to put all the user installed apps into a Fragment in this case I guess but I am unsure how to implement this...I have an Adapter class and everything.
Here is my InstalledAppActivity class which extends FragmentActivity to return all user downloaded apps.

way don't you just from youre main activity on click off the tab create a fragment with a listview in it and displays the data list there?? you can pars the list to the fragment bay saying
fragmentclass fragment = new fragmentclass(list);
fragment.show();
if youre having truble understanding fragments you can watch this great tutorial on it especialy the part on inter fragment communication is realy use full
In my Android app, I am trying to place a ListView in my FragmentActivity. Unfortunately there is no such thing as FragmentListActivity. The problem is that I can't call setListAdapter() and onListItemClick() methods.
So I did a lot of research and I went to my XML file and manually added the ListView there. Then instead of getListView(), I declared a ListView variable so I could call the methods on my new ListView variable. Unfortunately the method is still riddled with errors The method is unable to be resolved etc.
Here is my java code:
package com.spicycurryman.getdisciplined10.app;
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.content.ActivityNotFoundException;
import android.content.DialogInterface;

public class InstalledAppActivity extends FragmentActivity {

//Implementing the Listview Programatically

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Here is my XML File:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/Installed_List"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Try this..
You have missed onCreate
ListView InstalledAppList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.installed_apps);
InstalledAppList = (ListView) findViewById(R.id.Installed_List);
packageManager = getPackageManager();
new LoadApplications().execute();
InstalledAppList.setOnItemClickListener(new OnItemClickListener()){
#Override
public void onItemClick(AdapterView <?> arg0, View view, int index, long id){
ApplicationInfo app = applist.get(index);
try {
Intent intent = packageManager
.getLaunchIntentForPackage(app.packageName);
if (null != intent) {
startActivity(intent);
}
} catch (ActivityNotFoundException e) {
Toast.makeText(InstalledAppActivity.this, e.getMessage(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(InstalledAppActivity.this, e.getMessage(),
Toast.LENGTH_LONG).show();
}
}
});
}
and remove onCreateView and add ItemClickListener also inside onCreate
public class MyAndroidVersionListFragment extends ListFragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
CustomDoctorsListAdapter adapter= new CustomDoctorsListAdapter(getActivity(), getResources().getStringArray(R.array.doctors_name), getResources().getStringArray(R.array.doctors_address),
getResources().getStringArray(R.array.doctors_category), getResources().obtainTypedArray(R.array.doctors_rating), getResources().getIntArray(R.array.doctors_clinic_distance));
getResources().obtainTypedArray(R.array.doctors_rating).recycle();
android.R.layout.simple_list_item_multiple_choice, android_versions);
setListAdapter(adapter);
Toast.makeText(getActivity(), "Mypostion"+position+"", Toast.LENGTH_LONG).show();
return super.onCreateView(inflater, container, savedInstanceState);
}
#Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
position = getArguments().getInt("second");
}
#Override
public void onStart() {
super.onStart();
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
}
try List fragment like this hope it will help you
