Navigation Drawer not closing

Navigation Drawer not closing - android

I have implemented a navigationdrawer in android.I don't understand how to close the drawer when a item from the drawer list is selected.The foolowing code gives me a null pointer exception.
The mainactivity:
public class MainActivity extends ActionBarActivity {
String[] planet={"earth","mars","jupiter"};
ListView lv;
DrawerLayout mDrawerLayout;
NavigationDrawerFragment navigationDrawerFragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if(savedInstanceState==null){
earth earthfrag=new earth();
FragmentManager fragmentManager=getSupportFragmentManager();
FragmentTransaction transaction=fragmentManager.beginTransaction();
transaction.add(R.id.mainactivity,earthfrag,"earth").commit();
}
Toolbar toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
mDrawerLayout=(DrawerLayout)findViewById(R.id.nav_drawer);
navigationDrawerFragment = (NavigationDrawerFragment) getSupportFragmentManager().findFragmentById(R.id.drawer_fragment);
navigationDrawerFragment.setup(mDrawerLayout, toolbar);
lv= (ListView) findViewById(R.id.listView);
lv.setAdapter(new ArrayAdapter<String>(getApplicationContext(),android.R.layout.simple_list_item_1,planet));
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
FragmentManager fragmentManager=getSupportFragmentManager();
FragmentTransaction transaction=fragmentManager.beginTransaction();
if(position==2){
jupiter jupiterfrag=new jupiter();
transaction.replace(R.id.mainactivity, jupiterfrag, "jupiter").commit();
}
if (position==1){
mars marsfrag=new mars();
transaction.replace(R.id.mainactivity,marsfrag,"mars").commit();
}
if (position==0){
earth earthfrag=new earth();
transaction.replace(R.id.mainactivity,earthfrag,"earth").commit();
}
mDrawerLayout.closeDrawer(lv);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
The NavigationDrawerFragment :
public class NavigationDrawerFragment extends Fragment {
private ActionBarDrawerToggle mActionBarDrawerToggle;
private DrawerLayout mDrawerLayout;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
return inflater.inflate(R.layout.drawer_fragment,container,false);
}
public void setup(DrawerLayout drawerLayout,Toolbar toolbar) {
mDrawerLayout=drawerLayout;
mActionBarDrawerToggle=new ActionBarDrawerToggle(getActivity(),mDrawerLayout,toolbar,R.string.drawer_open,R.string.drawer_close){
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
};
mDrawerLayout.setDrawerListener(mActionBarDrawerToggle);
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mActionBarDrawerToggle.syncState();
}
});
}
}
The activity_main.xml:
<?xml version="1.0"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/nav_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity">
<include
android:id="#+id/app_bar"
layout="#layout/app_bar" />
<RelativeLayout
android:id="#+id/mainactivity"
android:layout_width="match_parent"
android:layout_height="match_parent"></RelativeLayout>
</LinearLayout>
<fragment
android:id="#+id/drawer_fragment"
android:name="com.example.joy.ecoapp.NavigationDrawerFragment"
android:layout_width="280dp"
android:layout_height="match_parent"
android:layout_gravity="start"
tools:layout="#layout/drawer_fragment" />
</android.support.v4.widget.DrawerLayout>

I believe you need to wrap the fragment in a container, e.g. a LinearLayout. Then use that container as the drawer:
<LinearLayout
android:id="#+id/lv_wrapper"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#android:color/background_light"
android:padding="5dp" >
<fragment
android:layout_height="match_parent"
android:layout_width="match_parent"
android:id="#+id/drawer_fragment"
tools:layout="#layout/drawer_fragment"
android:name="com.example.joy.ecoapp.NavigationDrawerFragment" />
</LinearLayout>
Then in your code instead of calling
mDrawerLayout.closeDrawer(lv);
call it with your new wrapper:
mDrawerLayout.closeDrawer(findViewById(R.id.lv_wrapper);

Not working scrolling of RecyclerView in layout extended from base activity

I need some help with my android application. The problem I had faced is that I had created Base activity, that controls Drawer Layout and toolbar. When I am extending it in activity for Relative Layout and nested Recycle View, I get a problem that a can't scroll it (But, when activity is starting, I can catch the moment and do it, but one time). Another situation - I opened an application without extending Base activity in my activity for RecycleView and it works okay.

}
Thanks, everybody, who will help me

You first need to remove
adapter.notifyDataSetChanged()
After this if you use recycler view inside nested scrolling
You need to add a single line
recyclerView.setNestwdScrollingenable(false)

I resolved the problem. I replace my logic for recyclerview in frament, and mainly change, that I do is - in layout with appbar, I replaced <include layout="#layout/content"/> to outside of AppBarLayout and change line:
android:layout_height="match_parent"
android:background="#color/colorWhite"
to this:
android:layout_height="wrap_content"

Try this code its working for me
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.app_name, R.string.app_name) {
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
};
drawerLayout.addDrawerListener(actionBarDrawerToggle);

Try this
ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.open
, R.string.close) {
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
};

use this code to change navigation icon
drawerToggle.setDrawerIndicatorEnabled(false);
toolbar.setNavigationIcon(R.drawable.ic_nav);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
drawerLayout.openDrawer(Gravity.LEFT);
}
});
drawerToggle.syncState();

i hope this works for you. please change your setUp function like this.
public void setUp(int fragmentId, DrawerLayout drawerLayout, final Toolbar toolbar) {
containerView = getActivity().findViewById(fragmentId);
mDrawerLayout = drawerLayout;
//add here this code
toolbar.setNavigationIcon(R.drawable.iv_menu);
mDrawerToggle = new ActionBarDrawerToggle(getActivity(), drawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close) {
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActivity().invalidateOptionsMenu();
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
getActivity().invalidateOptionsMenu();
}
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
toolbar.setAlpha(1 - slideOffset / 2);
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerLayout.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
}

Android Navigation Drawer Content Frame Cannot be resolved

I am using the following code to implement a simple navigation drawer based on the sample given in the Android Developers site.
public class MainActivity extends ActionBarActivity {
Toolbar toolbar;
DrawerLayout mDrawerLayout;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
ListView mDrawerList;
private String[] mDrawerItems;
ActionBarDrawerToggle drawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
mDrawerItems = getResources().getStringArray(R.array.graph_array);
mDrawerList = (ListView) findViewById(R.id.list_view_drawer);
setSupportActionBar(toolbar);
mTitle = mDrawerTitle = getTitle();
toolbar.setNavigationIcon(R.drawable.ic_menu_white_24dp);
mDrawerLayout = (DrawerLayout) findViewById(R.id.navDrawer);
mDrawerLayout.setStatusBarBackgroundColor(getResources().getColor(R.color.primaryDark));
drawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.abc_action_bar_home_description, R.string.abc_action_bar_home_description) {
public void onDrawerClosed(View view) {
getSupportActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(drawerToggle);
if (savedInstanceState == null) {
selectItem(0);
}
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mDrawerItems));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
}
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
}
}
private void selectItem(int position) {
// update the main content by replacing fragments
//Fragment fragment = new PlanetFragment();
//Bundle args = new Bundle();
//args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position);
//fragment.setArguments(args);
if (position == 0) {
Fragment frag1 = new Fragment1();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, frag1).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
setTitle(mDrawerItems[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else if (position == 1) {
}
}
#Override
public void setTitle(CharSequence title) {
mTitle = title;
getSupportActionBar().setTitle(mTitle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
drawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggls
drawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public static class PlanetFragment extends Fragment {
public static final String ARG_PLANET_NUMBER = "planet_number";
public PlanetFragment() {
// Empty constructor required for fragment subclasses
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_planet, container, false);
int i = getArguments().getInt(ARG_PLANET_NUMBER);
String planet = getResources().getStringArray(R.array.graph_array)[i];
int imageId = getResources().getIdentifier(planet.toLowerCase(Locale.getDefault()),
"drawable", getActivity().getPackageName());
((ImageView) rootView.findViewById(R.id.image)).setImageResource(imageId);
getActivity().setTitle(planet);
return rootView;
}
}
}
But I get an error saying "content_frame cannot be resolved". How do I fix this ?

Change the id of the frame... its normally container... But change it to content_frame and you are good.

Showing Map in a Fragment

In my application i want to show google map in a Fragment. My activity class is given below.
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mPlanetTitles;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = mDrawerTitle = getTitle();
mPlanetTitles = getResources().getStringArray(R.array.planets_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
GravityCompat.START);
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_launcher, R.string.app_name,
R.string.action_settings) {
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
selectItem(0);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_websearch).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
switch (item.getItemId()) {
case R.id.action_websearch:
Intent intent = new Intent(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY, getActionBar().getTitle());
if (intent.resolveActivity(getPackageManager()) != null) {
startActivity(intent);
} else {
Toast.makeText(this, "Nothing", Toast.LENGTH_LONG).show();
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private class DrawerItemClickListener implements
ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
selectItem(position);
}
}
private void selectItem(int position) {
onItemSelected(mPlanetTitles[position]);
mDrawerList.setItemChecked(position, true);
setTitle(mPlanetTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
}
#Override
public void setTitle(CharSequence title) {
mTitle = title;
getActionBar().setTitle(mTitle);
}
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
public void onItemSelected(String link) {
DetailFragment fragment = (DetailFragment) getFragmentManager()
.findFragmentById(R.id.detailFragment);
fragment.setText(link);
}
}
As shown in the code in the Activity i am using a DrawyerLayout inside that there are four items. When the user press the Item. I am showing Fragment where the MapFragment kept inside.
Please see the Main Xml layout file.
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<fragment
android:id="#+id/detailFragment"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2"
class="com.example.mynavigation.DetailFragment"
android:visibility="invisible" >
</fragment>
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"

android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>
My Fragment Class.
public class DetailFragment extends Fragment {
GoogleMap map ;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
System.out.println("kkkkkkkkkkkk");
View view = inflater.inflate(R.layout.fragment_rssitem_detail,
container, true);
return view;
}
public void setText(String item) {
System.out.println("set Tewxt");
TextView view = (TextView) getView().findViewById(R.id.detailsText);
view.setText(item);
}
}
And the fragment_rssitem_detail.xml file
<?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:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|center_vertical"
android:layout_marginTop="20dip"
android:text="Default Text"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="30dip" />
<FrameLayout
android:id="#+id/map_frame"
android:layout_width="fill_parent"
android:layout_height="match_parent" >
<fragment
android:id="#+id/map"
class="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="8dp" />
</FrameLayout>
<!-- <ListView
android:id="#+id/list_fragment"
android:name="com.myapp.ListFragment"
android:layout_width="wrap_content"
android:layout_height="fill_parent" /> -->
</LinearLayout>

Put only LinearLayout at where you want to put map in your xml and push map programatically as below:
private SupportMapFragment mapFragment;
mapFragment = new SupportMapFragment();
addFragment(lnrMap.getId(), mapFragment); //lnrMap is your LinearLayout from xml.
googleMap = mapFragment.getExtendedMap();
AddFragment Method(),Put this method in your DetailFragment class:
public void addFragment(int layoutId, Fragment fragment) {
FragmentManager fm = getChildFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(layoutId, fragment);
ft.commit();
}
