ID value returning null

I am new to android programming and would like some help or advise as to why whenever I try and update records in the database by clicking on the update button the id that is meant to passed through is null so it wont update. How do I get it so that the Id is not null when updating.
DatabaseHelper.java
package com.example.warre.sqlliteapp;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
public class DatabaseHelper extends SQLiteOpenHelper {
public static final String DATABASE_NAME = "tracker.db";
public static final String TABLE_NAME = "tracker_table";
public static final String COL_1 = "ID";
public static final String COL_2 = "SALES";
public static final String COL_3 = "FOLLOW";
public static final String COL_4 = "DONE";
public static final String COL_5 = "LEADER";
public static final String COL_6 = "TRAIN";
public DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, 1);
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("create table " + TABLE_NAME +" (ID INTEGER PRIMARY KEY AUTOINCREMENT,SALES INTEGER,FOLLOW INTEGER,DONE INTEGER, LEADER INTEGER, TRAIN INTEGER)");
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS "+TABLE_NAME);
onCreate(db);
}
public boolean insertData(String sales,String follow,String done, String leader, String train) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(COL_2,sales);
contentValues.put(COL_3,follow);
contentValues.put(COL_4,done);
contentValues.put(COL_5,leader);
contentValues.put(COL_6, train);
long result = db.insert(TABLE_NAME,null ,contentValues);
if(result == -1)
return false;
else
return true;
}
public Cursor getAllData() {
SQLiteDatabase db = this.getWritableDatabase();
Cursor res = db.rawQuery("select * from "+TABLE_NAME,null);
return res;
}
public boolean updateData(String id,String sales,String follow,String done, String leader, String train) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(COL_1,id);
contentValues.put(COL_2,sales);
contentValues.put(COL_3,follow);
contentValues.put(COL_4,done);
contentValues.put(COL_5, leader);
contentValues.put(COL_6, train);
db.update(TABLE_NAME, contentValues, "ID = ?",new String[] { id });
return true;
}
public Integer deleteData (String id) {
SQLiteDatabase db = this.getWritableDatabase();
return db.delete(TABLE_NAME, "ID = ?",new String[] {id});
}
}

The problem is happening in the updateData() where editTextId is getting null or returning null.

Error Log
Eror Log

Okay so your cause of error is because of this line
editTextId = (EditText)findViewById(R.id.editText_id);
as there is no EditText in your activity_money.xml layout and you are trying to get its reference so you are getting null reference.
First add it in xml or remove the edittext lines from your java file.

How to link tablerow content to checkbox?

Imagine I have checkbox with criteria in main activity and table in second activity. I want to link table to checkbox so for example when price and mileage is checked, only price and mileage columns are displayed. But when nothing is checked table is not appearing.I would really appreciate if someone could explain how to do it or give me a link to tutorial.

In your OnClickButtonListener, you are declaring a lot of new View.OnClickListener()s, but you are just creating the implementations then not doing anything with them. Those should all be removed. Your method should look like this:
public void OnClickButtonListener() {
button_next = (Button)findViewById(R.id.button);
button_next.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
intent.putExtra("Price", check1.isChecked());
intent.putExtra("Year", check2.isChecked());
intent.putExtra("Capacity", check3.isChecked());
intent.putExtra("Gas", check4.isChecked());
intent.putExtra("Mileage", check5.isChecked());
startActivity(intent);
}
}
);
}
See how it parallels with the code in the onCreate method in the SecondActivity?
After this change, you should see about what you expect to see.
Your first step would put be to create an Intent that has the values of the checkboxes, and pass that to the second activity:
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
intent.putExtra("name", check1.isChecked());
// same for other checkboxes
startActivity(intent);
Next, in your SecondActivity access those values:
boolean hasName = getIntent().getBooleanExtra("name", true);
When you are creating your TableRow, set the visibility based on the values:
TextView carName = (TextView) findViewById(R.id.car_name); // you will need to create this id in your layout
carName.setVisibility(hasName ? View.VISIBLE : View.GONE);
Remember, if nothing is checked then you won't see anything, so you should probably start MainActivity with all the checkboxes checked to begin with.

how to switch from a fragment in a fragmentActivity to the Activity in android

I have a fragment class in with I am having few fragment tabs. each of them are opening another dedicated fragment. but I want to change one fragment to open an activity class. I have gone through many examples but didn't the problem solve. everytime my application goes crashed.

Step 1
- declare your activity inside of the manifest
Step 2
- starActivity(new Intent(getAcivity(), MyClass.class));
Step 3
- post your logcat if this didn't help while it should !
Edit: the issue seems that you are not setting a height to your layouts, base on your layout that you posted you have five layouts that are missing android:layout_height please add that and force close shall be gone.

Use these method to save and get values from any where in your app change parameter according to your requirment
this method to save value in shared prefrences
public static void setPref(Context c, String pref, String val) {
Editor e = PreferenceManager.getDefaultSharedPreferences(c).edit();
e.putString(pref, val);
e.commit();
}
this method to get value from shared prefrences

Android custom control is this possible?

Im searching this since yesterday. I've got on many Activities some piece of code which displays user name and login. I dont want to copy and paste code in layout into every Activity, but I want something just like user controls in .NET. I've read a lot of topic about custom controls but or I don't understand it or its not possible do to this (I dont belive in that option)

Yes it is possible. Look at this sample. It is a custom Numeric Keyboard or a custom View or a custom user control. Customize it and create your own user control:
