Error when inflating class Fragment

I have bug I don't know how to fix.
I need to add a Fragment, but it won't work.
Everything happens in void firstTime() and the error shows that it's on line setContentView(R.layout.activity_main);.
I really don't know how to fix this.
I tried a lot of things, but it just does not work.
Please, help me.

Everything happens in firstTime() void and error shows that it's on line setContentView(R.layout.activity_main);.
You can't do this.
start() and firstTime() are not the entrypoints to your activity/application.
onCreate() is and that is where you can only call setContentView(R.layout.activity_main).
Even so, static methods that "load" any Activity aren't going to work.
public static void load(){
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(can);
if (!prefs.getBoolean("firstTime", false)) {
can.firstTime(); // This doesn't work like this
}
}
Especially if you did MainActivity.load() somewhere else in your other classes.
Reading your error, see that start() -> setContentView() is causing the problem...
at android.support.v7.app.AppCompatActivity.setContentView(AppCompatActivity.java:143)
at com.robertas.parking.bestfreeparking.MainActivity.start(MainActivity.java:161)
at com.robertas.parking.bestfreeparking.MainActivity$8.onClick(MainActivity.java:356)
at android.view.View.performClick(View.java:4780)
And the real error message
Duplicate id 0x7f0f00e8, tag null, or parent id 0x7f0f00e7 with another fragment for com.google.android.gms.maps.SupportMapFragment
Meaning that the Fragment "#+id/maps" has already been added into the FragmentManger of the Activity class, so it has been duplicated.
Activities should ideally not call setContentView outside of onCreate.
Reason being = You call setContentView, therefore removing the MapFragment (and other Views) entirely from the root view, so 1) the FragmentManger cannot find anything previously added, 2) Any view you had used findViewById before (probably) no longer exists.
If you are wanting to "replace" the content of some Activity, then you should use Fragments + a FrameLayout + a FragmentTransaction.replace() method call.

Make sure you compile com.google.android.gms.maps in your build.gradle file. Add this to your dependencies if it's not there:
dependencies {
<other dependencies>
compile 'com.google.android.gms:play-services-maps:10.2.0'
}
And remember to import it in your java file:
import com.google.android.gms.maps.SupportMapFragment;
And on the tools:context, it should be .MainActivity

Preference fragment returns null on transaction

I'm trying to implement a preference fragment in my app, so I set preferences.xml file, fragment that is supposed to show preferences, and fragment transaction. When I try to show SettingsFragment, the app crashes with this error log:

Why is this object null? How else am I supposed to set up a setting fragment? I know that solution for this is proably very simple, but somehow I cannot figure this out by myself. Here's my code:
Part that calls fragment transaction from MainActivity:
public boolean onNavigationItemSelected(MenuItem item) {
Fragment fragment = null;
Class fragmentClass = null;
int id = item.getItemId();
if (id == R.id.nav_news) {
fragmentClass = NewsFragment.class;
} else if (id == R.id.nav_map) {
fragmentClass = CatFragment.class;
} else if (id == R.id.nav_buildings) {
fragmentClass = BuildingsFragment.class;
} else if (id == R.id.nav_settings) {
fragmentClass = SettingsFragment.class;
} else if (id == R.id.nav_info) {
fragmentClass = AppInfoFragment.class;
} else if (id == R.id.nav_bugreport) {
fragmentClass = ContactFragment.class;
}
try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frameLayoutForFragments, fragment).commit();
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
My preferences.xml:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<CheckBoxPreference
android:defaultValue="false"
android:key="saveLastPosition"
android:summary="1st check box"
android:title="Check"/>
<CheckBoxPreference
android:defaultValue="true"
android:key="keepScreenOn"
android:summary="2nd check box"
android:title="Box"/>
</PreferenceScreen>
And my SettingsFragment:
public class SettingsFragment extends PreferenceFragment {
public SettingsFragment() {
// Required empty public constructor
}
public static SettingsFragment newInstance() {
SettingsFragment fragment = new SettingsFragment();
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
}
}

Well from what I can tell you are passing a null fragment to your fragment manager. As you will notice:
Fragment fragment = null;
Class fragmentClass = SettingsFragment.class;
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frameLayoutForFragments, fragment).commit();
You have:
Fragment fragment = null;
You never actually declare this as a SettingsFragment. You should either have:
Fragment fragment = new SettingsFragment();
Or declare it in your replace statement.
Class fragmentClass = SettingsFragment.class;
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frameLayoutForFragments, new SettingsFragment()).commit();

How to get ListView data from one activity to another using setOnClickListener

In my listview there are to feilds,ward number and the date.i want to get these data to new activity when i'am clicking a listview.but in this there is a runtime error and i have no idea to how to fix it.
this is my dashboardActivity.java file,
public class DashboardActivity extends ListActivity implements FetchDataListener{
UserFunctions userFunctions;
Button btnLogout;
TextView resultView;
private ProgressDialog dialog;
//private String email;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/**
* Dashboard Screen for the application
* */
// Check login status in database
userFunctions = new UserFunctions();
if(userFunctions.isUserLoggedIn(getApplicationContext())){
setContentView(R.layout.dashboard);
initView();
ListView lv = getListView();
// listening to single list item on click
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// selected item
TextView txtviewWard= (TextView) view.findViewById(R.id.ward_number);
String ward = txtviewWard.getText().toString();
TextView txtviewDate= (TextView) view.findViewById(R.id.date_time);
String dateTime = txtviewDate.getText().toString();
// Launching new Activity on selecting single List Item
Intent i = new Intent(getApplicationContext(), SingleListItem.class);
// sending data to new activity
i.putExtra("ward", ward);
i.putExtra("dateTime", dateTime);
startActivity(i);
}
});
btnLogout = (Button) findViewById(R.id.btnLogout);
btnLogout.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
// TODO Auto-generated method stub
userFunctions.logoutUser(getApplicationContext());
Intent login = new Intent(getApplicationContext(), LoginActivity.class);
login.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(login);
// Closing dashboard screen
finish();
}
});
}else{
// user is not logged in show login screen
Intent login = new Intent(getApplicationContext(), LoginActivity.class);
login.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(login);
// Closing dashboard screen
finish();
}
}
private void initView() {
// show progress dialog
dialog = ProgressDialog.show(this, "", "Loading...");
Intent intent = getIntent();
String email = intent.getStringExtra(LoginActivity.EMAIL);
String url = "http://pubbapp.comze.com/pubapp1.php?email=" + email;
FetchDataTask task = new FetchDataTask(this);
task.execute(url);
}
public void onFetchComplete(List<Application> data) {
// dismiss the progress dialog
if(dialog != null) dialog.dismiss();
// create new adapter
ApplicationAdapter adapter = new ApplicationAdapter(this, data);
// set the adapter to list
setListAdapter(adapter);
}
public void onFetchFailure(String msg) {
// dismiss the progress dialog
if(dialog != null) dialog.dismiss();
// show failure message
Toast.makeText(this, msg, Toast.LENGTH_LONG).show();
}
}
this is my SingleListItem.java file,
public class SingleListItem extends Activity{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.single_list_item_view);
TextView txtWard = (TextView) findViewById(R.id.ward_number);

Intent i = getIntent();
// getting attached intent data
String wardNumber = i.getStringExtra("ward");
String dateTime = i.getStringExtra("dateTime");
// displaying selected product name
txtWard.setText(wardNumber);
txtDate.setText(dateTime);
}
this is my xml file,
<?xml version="1.0" encoding="utf-8"?>

thank you.

In first activity, pass the data as a bundle using putExtras:
// sending data to new activity
Bundle b = new Bundle();
b.putString("ward", ward);
b.putString("dateTime", dateTime);
i.putExtras(b);
In second activity, retrieve the bundle and parse the data as follows:
Bundle b = getIntent().getExtras();
if (b != null)
{
String wardNumber = b.getString("ward");
String dateTime = b.getString("dateTime");
}

try this....
ListView lv = getListView();
// listening to single list item on click
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
//your code
}
});

get data like this in ur second activity:
Bundle b = savedInstanceState.getExtras();
if(b!=null)
{
String ward =b.getString("ward");
String dateTime =b.getString("datetime");
}
bundle is responsible to getexras(),so use this.it worked for me and my other friends.

How to use Bottom tabActivity in my Activity itself

I want to use bottom tab in my activity,in my old activity itself having some function,without using seperate activity for tab,can i use tab functions in my activity itself,I tried like this.
public class GinfyActivity extends Activity {

replace these two lines
public class GinfyActivity extends Activity
TabHost mTabHost = (TabHost)findViewById(android.R.id.tabhost);
with following
public class GinfyActivity extends TabActivity
TabHost mTabHost = getTabHost();
EDIT
change activity which you want to display in following line.
Intent intentAndroid = new Intent().setClass(this, Your_Activity.class);
And if you want only Tab then it's better to use ActionBar as TabHost is deprecated.
Full Example of TabHost
To use ActionBar here is sample code (use Sherlock or appcompat Library for < API 11)
public class MainActivity extends Activity implements TabListener {
ActionBar actionBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
actionBar=getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.addTab(actionBar.newTab().setText("TAB 1").setTabListener(this));
actionBar.addTab(actionBar.newTab().setText("TAB 2").setTabListener(this));
actionBar.addTab(actionBar.newTab().setText("TAB 3").setTabListener(this));
}
#Override
