How to show properly my data in RecyclerView?

This is the updated code for my RececlerView to show data in my SQLite Database but still I cant make the data to show in my recycler view but there is no errors in my app.
The applications only show "No API Data" which is from this part of my code.
Toast.makeText(this, "No API Data", Toast.LENGTH_SHORT).show();
I will show you the codes.
This is a part of my DatabaseHelper the method on Listing the data in myDatabase for RecyclerView.
public boolean checkUser(String email) {
// array of columns to fetch
String[] columns = {
Timerecordshelper.BeneficiaryEntry._ID
};
SQLiteDatabase db = this.getReadableDatabase();
// selection criteria
String selection = Timerecordshelper.BeneficiaryEntry.COL_1 + " = ?";
// selection argument
String[] selectionArgs = {email};
// query user table with condition
/**
* Here query function is used to fetch records from user table this function works like we use sql query.
* SQL query equivalent to this query function is
* SELECT user_id FROM user WHERE user_email = 'test#gmail.com';
*/
Cursor cursor = db.query(Timerecordshelper.BeneficiaryEntry.TABLE_NAME_IN, //Table to query
columns, //columns to return
selection, //columns for the WHERE clause
selectionArgs, //The values for the WHERE clause
null, //group the rows
null, //filter by row groups
null); //The sort order
int cursorCount = cursor.getCount();
cursor.close();
db.close();
if (cursorCount > 0) {
return true;
}
return false;
}
public List<TimeinData> getAllTimeinData() {
// array of columns to fetch
String[] columns = {
Timerecordshelper.BeneficiaryEntry.COL_1,
Timerecordshelper.BeneficiaryEntry.COL_2,
Timerecordshelper.BeneficiaryEntry.COL_3,
Timerecordshelper.BeneficiaryEntry.COL_4,
Timerecordshelper.BeneficiaryEntry.COL_5,
};
// sorting orders
String sortOrder =
Timerecordshelper.BeneficiaryEntry.COL_1 + " ASC";
List<TimeinData> TimeList = new ArrayList<TimeinData>();
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.query(Timerecordshelper.BeneficiaryEntry.TABLE_NAME_IN, //Table to query
columns, //columns to return
null, //columns for the WHERE clause
null, //The values for the WHERE clause
null, //group the rows
null, //filter by row groups
sortOrder); //The sort order
// Traversing through all rows and adding to list
if (cursor.moveToFirst()) {
do {
TimeinData Timerecords = new TimeinData();
Timerecords.setId(Integer.parseInt(cursor.getString(cursor.getColumnIndex(Timerecordshelper.BeneficiaryEntry.COL_1))));
Timerecords.setIn(cursor.getString(cursor.getColumnIndex(Timerecordshelper.BeneficiaryEntry.COL_2)));
Timerecords.setCustomer(cursor.getString(cursor.getColumnIndex(Timerecordshelper.BeneficiaryEntry.COL_3)));
Timerecords.setBranch(cursor.getString(cursor.getColumnIndex(Timerecordshelper.BeneficiaryEntry.COL_4)));
Timerecords.setMachine(cursor.getString(cursor.getColumnIndex(Timerecordshelper.BeneficiaryEntry.COL_5)));
// Adding user record to list
} while (cursor.moveToNext());
}
cursor.close();
db.close();
// return user list
return TimeList;
}

#Override

Timerecordshelper.java

}
This codes acts as the gettersetter for my Recycleview to get data in SQLite.

I expect that the apps shows all the data in TABLE_NAME_IN, but on the otherhand as I said it only shows the No "API Data".

remove android:onClick="onClick" line. That should be work.

Null pointer exception whilst adding to the DB

I'm developing a simple bird-watching log app for one of my classes at college and I seem to not be able to spot what the heck is going wrong, so after spending a few days banging my head against the wall, I suppose it'd make more sense to just ask for someone with a fresh pair of eyes to have a look.
The app is really simple - I have two activities, one with a ListView, that gets populated by the DB (MainActivity) and another, that takes the arguments to create a new entry (AddActivity). Besides these I have a DBHelper (MySQLiteHelper) to handle my DB calls, a simple class to describe how my object should look like (Sighting), a DataSource class (SightingDataSource) to handle facilitate the calls to the helper and a bunch of non-relevant resources (layouts, etc.) The AddActivity blows up with null pointer exceptions whilst calling the addSighting method. It also for whatever reason doesn't like the int typecast of the bCount field, so for testing purposes I've set a static int, just whilst I figure out the exception portion of my problem.
Here's my source:
AddActivity:
package com.vladislavtachev.cscb763;

bCountFld = (EditText) findViewById(R.id.bCountFld);
setContentView(R.layout.activity_add);
addSightBtn = (Button) findViewById(R.id.addSightBtn);
addSightBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
addSight(v);
}
});
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) { return true; }
return super.onOptionsItemSelected(item);
}
public void addSight(View view){
long time = System.currentTimeMillis()/1000L;
datasource.addSighting(locFld.getText().toString(),

All help is appreciated!
Cheers,
V./

datasource is never initialized in AddActivity. You also call setContentView twice. Delete the second one.

you should Always Check to see if the cursor is null.
if(cursor!=null curosr.moeToNext()){}..
and to close it
if (cursor!=null && !cursor.isClosed){cursor.close();}

Please anyone help me connection with main activity and Adapterclass.

Please anyone tell me how to connect MainActivity class with adapterClass, I am not able to connect to my sqllite database. Any help would be greatly appreciated.
Below is my main activity class
public class LoginActivity extends Activity {
EditText nameText,phoneText;
Button registeredButton,newUser;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
newUser =(Button)findViewById(R.id.new_user);
newUser.setOnClickListener(new View.OnClickListener()
#Override
public void onClick(View v) {
nameText=(EditText)findViewById(R.id.user_text);
phoneText=(EditText)findViewById(R.id.pass_text);
String name= nameText.getText().toString();
String phone=phoneText.getText().toString();
AdapterClass ad1=new AdapterClass(getApplicationContext(),DatabaseDetail.REGISTER);
ad1.Open();
Cursor cursor=ad1.query("SELECT * FROM CUS_REGISTER WHERE CUS_NAME=? AND CUS_PHONE=?",new String[] { name, phone });
Cursor cursor = ad1.fetchRecords(new String[]{}, null);
startManagingCursor(cursor);
cursor.moveToFirst();
if(cursor.getCount() > 0)
{
Toast.makeText(getApplicationContext(), "Sucess", 5000).show();
}else{
}
}
});
}
}
And this my adapter class code
public Cursor query(String args, String[] pColumnValues) {
