how to add Activity class in DrawerLayout in android?

I have some slides with ViewPager that shows application help and I want to show it in DrawerLayout too.
this is HelpActivity.class:
public class HelpActivity extends Activity {
private ViewPager viewPager;
private MyViewPagerAdapter myViewPagerAdapter;
private LinearLayout dotsLayout;
private TextView[] dots;
private int[] layouts;
private Button btnSkip, btnNext;
private PrefManager prefManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Checking for first time launch - before calling setContentView()
prefManager = new PrefManager(this);
if (!prefManager.isFirstTimeLaunch()) {
launchHomeScreen();
finish();
}
// Making notification bar transparent
if (Build.VERSION.SDK_INT >= 21) {
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
setContentView(R.layout.fragment_help);
viewPager = (ViewPager) findViewById(R.id.view_pager);
dotsLayout = (LinearLayout) findViewById(R.id.layoutDots);
btnSkip = (Button) findViewById(R.id.btn_skip);
btnNext = (Button) findViewById(R.id.btn_next);
// layouts of all welcome sliders
// add few more layouts if you want
layouts = new int[]{
R.layout.welcome_1,
R.layout.welcome_2,
R.layout.welcome_3,
R.layout.welcome_4,
R.layout.welcome_5,
R.layout.welcome_6,
R.layout.welcome_7};
// adding bottom dots
addBottomDots(0);
// making notification bar transparent
changeStatusBarColor();
myViewPagerAdapter = new MyViewPagerAdapter();
viewPager.setAdapter(myViewPagerAdapter);
viewPager.addOnPageChangeListener(viewPagerPageChangeListener);
btnSkip.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
launchHomeScreen();
}
});
btnNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// checking for last page
// if last page home screen will be launched
int current = getItem(+1);
if (current < layouts.length) {
// move to next screen
viewPager.setCurrentItem(current);
} else {
launchHomeScreen();
}
}
});
}
private void addBottomDots(int currentPage) {
dots = new TextView[layouts.length];
int[] colorsActive = getResources().getIntArray(R.array.array_dot_active);
int[] colorsInactive = getResources().getIntArray(R.array.array_dot_inactive);
dotsLayout.removeAllViews();
for (int i = 0; i < dots.length; i++) {
dots[i] = new TextView(this);
dots[i].setText(Html.fromHtml("•"));
dots[i].setTextSize(35);
dots[i].setTextColor(colorsInactive[currentPage]);
dotsLayout.addView(dots[i]);
}
if (dots.length > 0)
dots[currentPage].setTextColor(colorsActive[currentPage]);
}
private int getItem(int i) {
return viewPager.getCurrentItem() + i;
}
private void launchHomeScreen() {
prefManager.setFirstTimeLaunch(false);
startActivity(new Intent(HelpActivity.this, MainActivity.class));
finish();
}
// viewpager change listener
ViewPager.OnPageChangeListener viewPagerPageChangeListener = new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
addBottomDots(position);
// changing the next button text 'NEXT' / 'GOT IT'
if (position == layouts.length - 1) {
// last page. make button text to GOT IT
btnNext.setText(/*getString(R.string.start)*/ "Start");
btnSkip.setVisibility(View.GONE);
} else {
// still pages are left
btnNext.setText(/*getString(R.string.next)*/ "Next");
btnSkip.setVisibility(View.VISIBLE);
}
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
};
/**
* Making notification bar transparent
*/
private void changeStatusBarColor() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.TRANSPARENT);
}
}
/**
* View pager adapter
*/
public class MyViewPagerAdapter extends PagerAdapter {
private LayoutInflater layoutInflater;
public MyViewPagerAdapter() {
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = layoutInflater.inflate(layouts[position], container, false);
container.addView(view);
return view;
}
#Override
public int getCount() {
return layouts.length;
}
#Override
public boolean isViewFromObject(View view, Object obj) {
return view == obj;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
View view = (View) object;
container.removeView(view);
}
}
}
this is PrefManager.class:
public class PrefManager {
SharedPreferences pref;
SharedPreferences.Editor editor;
Context _context;
// shared pref mode
int PRIVATE_MODE = 0;
// Shared preferences file name
private static final String PREF_NAME = "stand up-welcome";
private static final String IS_FIRST_TIME_LAUNCH = "IsFirstTimeLaunch";
public PrefManager(Context context) {
this._context = context;
pref = _context.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
editor = pref.edit();
}
public void setFirstTimeLaunch(boolean isFirstTime) {
editor.putBoolean(IS_FIRST_TIME_LAUNCH, isFirstTime);
editor.commit();
}
public boolean isFirstTimeLaunch() {
return pref.getBoolean(IS_FIRST_TIME_LAUNCH, true);
}
}
and I use this code for defining it to drawerLayout:
public void selectDrawerItem(MenuItem menuItem) {
if (menuItem.getItemId()== R.id.nav_item_help) {
//startActivityForResult(new Intent(this,HelpActivity.class),1000);
startActivity(new Intent(MainActivity.this,HelpActivity.class));
}
with clicking on help in drawer, nothing shows. what should I do?
This is MainActivity.class:
ublic class MainActivity extends AppCompatActivity {
public DrawerLayout drawerLayout;
public Toolbar toolbar;
public NavigationView navigationView;
public ActionBarDrawerToggle actionBarDrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentTransaction tx = getSupportFragmentManager().beginTransaction();
tx.replace(R.id.flContent, new HomeFragment());
tx.commit();
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//drawer layout
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
actionBarDrawerToggle= setupDrawerToggle();
drawerLayout.setDrawerListener(actionBarDrawerToggle);
//navigation view
navigationView= (NavigationView) findViewById(R.id.nvView);
// Setup drawer view
setupDrawerContent(navigationView);
actionBarDrawerToggle.syncState();
// default item of navigation view
// navigationView.getMenu().getItem(0).setChecked(true);
navigationView.setCheckedItem(R.id.nav_item_home);
}//onCreate
private ActionBarDrawerToggle setupDrawerToggle() {
return new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close);
}
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
selectDrawerItem(menuItem);
return true;
}
});
}
public void selectDrawerItem(MenuItem menuItem) {
if (menuItem.getItemId()==R.id.nav_item_setting){
startActivityForResult(new Intent(this, SettingActivity.class), 1002);
}
if (menuItem.getItemId()== R.id.nav_item_help) {
//startActivityForResult(new Intent(this,HelpActivity.class),1000);
startActivity(new Intent(MainActivity.this,HelpActivity.class));
}
// Create a new fragment and specify the fragment to show based on nav item clicked
android.support.v4.app.Fragment fragment = null /*new android.support.v4.app.Fragment()*/;

case R.id.nav_item_about:
fragmentClass =AboutFragment.class;
break;
default:
fragmentClass = HomeFragment.class;
break;
} try {
fragment = (android.support.v4.app.Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
// Insert the fragment by replacing any existing fragment
android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
android.support.v4.app.Fragment currentFragment = getSupportFragmentManager().findFragmentById(R.id.flContent);
if(currentFragment==null){
fragmentManager.beginTransaction().add(R.id.flContent, fragment).commit();
}else{
fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();
}
// Highlight the selected item has been done by NavigationView
menuItem.setChecked(true);
// Set action bar title
setTitle(menuItem.getTitle());
// Close the navigation drawer
drawerLayout.closeDrawers();
}
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggles
actionBarDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
return true;
} return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState); // `onPostCreate` called when activity start-up is complete after `onStart()`
}
#Override
public void onBackPressed() {
MainActivity.this.finish();
}
}

in your xml:
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right"
android:background="#drawable/background_drawer"
app:headerLayout="#layout/nav_header"
app:itemIconTint="#color/colorPrimary"
app:menu="#menu/menu_navigation" />
you have to add help options in your menu_navigation
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav_item_help"
android:icon="#drawable/profile_icon"
android:title="Help" />
</group>
</menu>
Also in your MainActivity:
public void selectDrawerItem(MenuItem menuItem) {
// Create a new fragment and specify the fragment to show based on nav item clicked
android.support.v4.app.Fragment fragment = null /*new android.support.v4.app.Fragment()*/;
Class fragmentClass = null;
switch(menuItem.getItemId()) {
case R.id.nav_item_setting:
Intent i = new Intent(MainActivity.this, SettingActivity.class);
startActivity(i);
break;
case R.id.nav_item_help:
Intent i = new Intent(MainActivity.this, HelpActivity.class);
startActivity(i);
break;
case R.id.nav_item_home:
fragmentClass = HomeFragment.class;
break;
case R.id.nav_item_knowledge:
fragmentClass = HomeFragment.class;
break;
/* case R.id.nav_item_help:
fragmentClass = HelpActivity.class;
break;*/
case R.id.nav_item_about:
fragmentClass =AboutFragment.class;
break;
default:
fragmentClass = HomeFragment.class;
break;
} try {
fragment = (android.support.v4.app.Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
// Insert the fragment by replacing any existing fragment
android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
android.support.v4.app.Fragment currentFragment = getSupportFragmentManager().findFragmentById(R.id.flContent);
if(currentFragment==null){
fragmentManager.beginTransaction().add(R.id.flContent, fragment).commit();
}else{
fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();
}
// Highlight the selected item has been done by NavigationView
menuItem.setChecked(true);
// Set action bar title
setTitle(menuItem.getTitle());
// Close the navigation drawer
drawerLayout.closeDrawers();
}
In your preference manager:
public void setFirstTimeLaunch(boolean isFirstTime) {
Editor editor = pref.edit();
editor.putBoolean(IS_FIRST_TIME_LAUNCH, isFirstTime);
editor.commit();
}
difference between startactivity and startActivityForResult is:
1. startActvity():
startActivity() will start the activity you want to start without worrying about getting any result from new child activity started by startActivity to parent activity.
2. startAcitvityForResult():
startAcitvityForResult() starts another activity from your activity and it expect to get some data from newly started child activity by startAcitvityForResult() and return that to parent activity.

What i do wrong?
Thanks for help.

If you don't want Android to restart the activity when screen is rotated (this destroys your fragment and causes NULLPointer exception) you can add
android:configChanges="orientation|screenSize"
inside the activity tag in your Androidmanifest.xml

Notification does not open the fragment?

I created a Notification and I want it to open a Fragment when clicked. It works in general, but when I have another Fragment open in my application at the time, it does not work.
For example, I have two Fragments: NoticiaFrag and EventoFrag. If I open my application and open the NoticiaFrag after pressing the home button of the device to minimize the application and receiving a notification to EventoFrag, when I click the notification opens NoticiaFrag and not EventoFrag.
To make this work I need close the application with the back button. After the application closes it works fine. I think I need to reopen the application when I click the Notification, but I don't know how.
The method that opens the Fragments from the Notification is in CustomDrawerLayout and called openFrag().
How can I solve this issue?
Notification
public class SendNotification {
public SendNotification(Context context, String title, String tickerText, String message, String url) {
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent;
Intent intent = new Intent(context, CustomDrawerLayout.class);
Bundle bd = new Bundle();
bd.putString("url", url);
intent.putExtras(bd);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
contentIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.logo)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setTicker(tickerText)
.setContentTitle(title)
.setShowWhen(true)
.setWhen(System.currentTimeMillis())
.setContentText(message);
mBuilder.setContentIntent(contentIntent);
Notification notification = mBuilder.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.vibrate = new long[]{150, 300, 150, 600};
mNotificationManager.notify(AndroidSystemUtil.randInt(), notification);
}
}

Manifest
<activity android:name=".menu.CustomDrawerLayout" android:launchMode="singleTop"/>

The problem is that Android by default doesn't deliver a new Intent to an Activity that is already running. If you close your app via the back button, the Activity is destroyed and the next time startActivity() is called a new instance is created and the new Intent delivered. If you leave the Activity via the home button, the Activity is not destroyed. When you call startActivity() in this case, the already running instance of the Activity is brought to the foreground, but a new Intent is not delivered.
To change this behaviour you can define your activity in the manifest with launchMode="singleTop":
<activity
...
android:launchMode="singleTop"
...
>
</activity>
In this case Android will deliver a new Intent via onNewIntent(), which you can override:
This is called for activities that set launchMode to "singleTop" in their package, or if a client used the FLAG_ACTIVITY_SINGLE_TOP flag when calling startActivity(Intent). In either case, when the activity is re-launched while at the top of the activity stack instead of a new instance of the activity being started, onNewIntent() will be called on the existing instance with the Intent that was used to re-launch it.
Just noticed the flags you're passing into your Intent. In that case you probably just have to override onNewIntent() in your Activity.
I've run into this problem myself before and asked a question here. There's some more background in that question, the accepted answer, and the comments.

My main drawer2 class looks like this:

}
}
Lastly my menu xml looks like this:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity" >
<item android:id="#+id/menu_search2"
android:actionViewClass="android.widget.SearchView"
android:title="Search"
android:icon="#android:drawable/ic_menu_search"
android:showAsAction="always|collapseActionView"
android:onClick="goToSearch" />
<item android:id="#+id/action_scan"
android:icon="#drawable/barcode"
android:onClick="scanBarcode"
android:showAsAction="ifRoom|collapseActionView"/>
</menu>
I cannot for the life of me figure out where this error is coming from.

I would recommend using the onOptionsItemSelected mechanism if possible instead of manually wiring the click methods.
Take a look at the documentation:
Android Developer Guide:Menus

You might have found a platform bug. Does it still happen if you set your activity theme to Theme.Holo or Theme.Holo.Light? Specifically, try it with something that isn't based on Theme.Holo.Light.DarkActionBar.
If this fixes your original problem please report this at http://b.android.com.

You have wrong method signature.
This is yours
public void goToSearch(MenuItem item){
}
This is how it should be
public void goToSearch(View v){
}
please see
http://developer.android.com/reference/android/R.attr.html#onClick
for reference
