Null Pointer on RecyclerView

I am getting a null pointer exception on the following statement within my recyclersetup method.
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
It is due to the following statement not setting a pointer to recyclerView in the previous statement which is
recyclerView = getView().findViewById(R.id.check_in_recent_row);
I cannot determine why I am not getting the recyclerView pointer established via this statement. the ID for the data is correct. What am I missing?
This is the entire fragment code

Your RecyclerView's ID is check_in_recent_recycler_view. Your findViewById call is using check_in_recent_row. These need to match.

I tried many times but failed to load parse data inside the tab fragments
if anyone know please help me thank you.

Your ListView is not at all attached to the swipe views. Plus, it's an activity. You need to swipe between Fragments. So move the Parse code into a Fragment with a ListView
And a Fragment is not an Adapter, so you need to implement nothing
public class Individuals extends Fragment { // No implements needed
// Code
}
Then setAdapter is not a method of the Fragment class, so you have to use the method of the ListView itself or use a ListFragment
Here's an example of a ListFragment
(code untested)
public class IndividualsFragment
extends android.support.v4.app.ListFragment
implements FindCallback<ParseObject> {
private List<ParseObject> mOrganization = new ArrayList<ParseObject>();
#Override
public void onViewCreated(View view, Bundle b) {
super.onViewCreated(view, b);
CustomAdaptor adaptor = new CustomAdaptor(getActivity(), mOrganization);
setListAdapter(adaptor);
// This is like calling fetchList()
ParseQuery.getQuery("Organization").findInBackground(this);
}
/**
* This is needed by implementing the callback on the class
**/
#Override
public void done(List<ParseObject> scoreList, ParseException e) {
if (e == null) {
Log.d("score", "Retrieved " + scoreList.size() + " Organization");
mOrganization.clear();
mOrganization.addAll(scoreList);
((CustomAdaptor) getListAdapter()).notifyDataSetChanged();
} else {
Log.d("score", "Error: " + e.getMessage());
}
}
}

you may need to call back listview in
OrganizationActivity.class

For that purpose, you need to create a custom adapter. You can find the implementation of custom adapter on the below link,
http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/
Above contain a nice tutorial on custom adapter to add icons, change colors of text and background on each list row....!
Here is also a good tutorial on custom adapter,
http://androidexample.com/How_To_Create_A_Custom_Listview_-_Android_Example/index.php?view=article_discription&aid=67&aaid=92
Here is a example,
Your activity's xml should be like this activity_main.xml,
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.rupomkhondaker.sonalibanklimited.NavigationDrawerFragment" />
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#cc0100cc"
android:id="#+id/menuList" />
</RelativeLayout>
Your Activity class:
public class MainActivity extends Activity {
private ListView listView1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String[] textString = {"Item1", "Item2", "Item3", "Item4"};
int[] drawableIds = {R.drawable.img_id_row1, R.drawable.img_id_row2, R.drawable.img_id_row3, R.drawable.img_id_row4};
CustomAdapter adapter = new CustomAdapter(this, textString, drawableIds);
listView1 = (ListView)findViewById(R.id.menuList);
listView1.setAdapter(adapter);
}
Create another layout for each row like below and name it row.xml,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp">
<ImageView android:id="#+id/imgIcon"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_marginRight="15dp"
android:layout_marginTop="5dp"
android:layout_marginBottom="5dp" />
<TextView android:id="#+id/txtTitle"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:textStyle="bold"
android:textSize="22dp"
android:textColor="#000000"
android:layout_marginTop="5dp"
android:layout_marginBottom="5dp" />
</LinearLayout>
Now, create a JAVA class and name it CustomAdapter.java:
public class CustomAdapter extends BaseAdapter {
private Context mContext;
private String[] Title;
private int[] imge;
public CustomAdapter(Context context, String[] text1,int[] imageIds) {
mContext = context;
Title = text1;
imge = imageIds;
}
public int getCount() {
// TODO Auto-generated method stub
return Title.length;
}
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return null;
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = getLayoutInflater();
View row;
row = inflater.inflate(R.layout.row, parent, false);
TextView title;
ImageView i1;
i1 = (ImageView) row.findViewById(R.id.imgIcon);
title = (TextView) row.findViewById(R.id.txtTitle);
title.setText(Title[position]);
i1.setImageResource(imge[position]);
return (row);
}
}

Get Logo (image) in menudrawer android

I want to place an image at the bottom of my menudrawer (google menu), but it doesn't work. I have researched the whole internet and tried everything I can imagine (in the java files and also in the xml files). It still doesn't work.
There is an example at the image below (red border):
The image below is my App with menudrawer:
I will appreciate any help.
Like I said before I want to get an image at the bottom of my menudrawer like the app above.
There are a few files related to the menu and in the activity_main.xml you got all elements (like the list items) of the whole menu. So I tried to place an imageview in the activity_main.xml but that does not work. From here I am stuck I really don't know how to do this. Thanks for your help.
Here is the code of activity_main.xml with the imageview that I have placed:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"

android:layout_height="match_parent">
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- Listview to display slider menu -->
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#color/black_overlay"
android:dividerHeight="1dp"

}
I know that the xml and java files below are not important, because this is only for the list items and not the whole menu. The reason I place this is that you maybe need it, too resolve the problem.
--
The code below is from NavDrawerItem.java :
package nl.vitaminen.solay.model;
public class NavDrawerItem {
private String title;
private int icon;
private String count = "0";
// boolean to set visiblity of the counter
private boolean isCounterVisible = false;
public NavDrawerItem(){}
public NavDrawerItem(String title, int icon){
this.title = title;
this.icon = icon;
}
public NavDrawerItem(String title, int icon, boolean isCounterVisible, String count){
this.title = title;
this.icon = icon;
this.isCounterVisible = isCounterVisible;
this.count = count;
}
public String getTitle(){
return this.title;
}
public int getIcon(){
return this.icon;
}
public String getCount(){
return this.count;
}
public boolean getCounterVisibility(){

this.icon = icon;
}
public void setCount(String count){
this.count = count;
}
public void setCounterVisibility(boolean isCounterVisible){
this.isCounterVisible = isCounterVisible;
}
}
and the final code below is related to the NavDrawerListAdapter.java:

Thank you for taking the time to resolve my problem. I hope that this is enough information for you.

Finally I solved my problem, I just changed in activity_main.xml the background of my listview as follows:
<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 to display Fragments -->
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- Listview to display slider menu -->
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#color/black_overlay"
android:dividerHeight="1dp"
android:listSelector="#drawable/list_selector"
android:background="#drawable/navigation_image_below"/> <!-- This is the line
I changed -->
<ImageView android:contentDescription="#string/app_name"
android:background="#drawable/solaylogo"
android:maxWidth="30dp"
android:maxHeight="10dp"/>
</android.support.v4.widget.DrawerLayout>
The image below is the navigation_image_below.png
I hope this is the good solution for this problem. Probably not, because if your screen resolution is more or less your image will be stretched.
I will appreciate if someone has another solution.

You're not instantiating any of the fragments you wish to become tabs in the FragmentPagerAdapter, getItem method. Instead you're returning null and therefore there are no views to fill the viewpager. I can see you've checked out his sample project, maybe take a closer look at the fragments you're trying to add to the viewpager. The above answer looks like a sound implementation.

Here is an example that I am using right now,
public class Formulario extends FragmentActivity implements ActionBar.TabListener {
private static final FragmentTransaction transaction = null;
public String ambitorec;
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "tab 1", "tab 2", "tab 3" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_formulario);
ambitorec = getIntent().getStringExtra("ambito");
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
also you need to add the adapter, in this case :
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
// tab 1 fragment activity
return new Formulario1Fragment();
case 1:
// tab2 fragment activity
return new Formulario2Fragment();
case 2:
// tab 3 fragment activity
return new MultimediaFragment();
}
return null;
}
#Override
public int getCount() {
// get item count - equal to number of tabs
return 3;
}
}
hope it helps, if you need more help ill try to explain

In FragmentPagerAdapter#getItem, you are not instantiating any of the fragments you want to become tabs. Instead of returning a fragment, you're returning null, which means there are no views to fill the viewpager. I see you've looked over his sample project, so look over the fragments you're trying to add to the viewpager again. The above response appears to be a second implementation.
