Create table Agent and insert values to sqlite table in Android

Create table Agent and insert values to sqlite table in Android - java

I am new in android app developement. I tried to insert values to SQLite database through the code below ; and it is not working. I'm desperate!
Can anyone pleaaaaase help me???
this is DatabaseHelper.JAVA
public class DatabaseHelper extends SQLiteOpenHelper {
private static final int DATABASE_VERSION = 1;
private static final String DATABASE_NAME = "agents.db";

Firestore data can't display on RecyclerView

The app quit when I change the line I am facing a problem when I try to develop an Android App that display the data from Firestore.
.
Can I know why it is not displaying the data on my RecyclerView and EventPage? I have rechecked everything, but I still can't find out why data doesn't show on EventPage.
EventPage.java
public class EventPage extends AppCompatActivity {
private static final String TAG = "DashboardFragment";
private FirestoreRecyclerAdapter<EventModel, EventViewHolder> adapter;
private RecyclerView recyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {

recyclerView.setAdapter(adapter);
FirebaseFirestore db = FirebaseFirestore.getInstance();
CollectionReference cRef = db.collection("event");
Query query = db.collection("event").orderBy("ASC").limit(10);
FirestoreRecyclerOptions<EventModel> options = new FirestoreRecyclerOptions.Builder<EventModel>()
.setQuery(query, EventModel.class)
.build();
adapter = new FirestoreRecyclerAdapter<EventModel, EventViewHolder>(options) {
#Override

}
#NonNull
#Override

//Changes on XML file. Try it.

make Sure your model class String variables are equal to your firestore data feild because it is very important to retrieve data from firestore
private String eventName;
private String eventDate;
private String eventVenue;
private String eventDescription;
//Constructor
public EventModel(){}
public EventModel(String eventName, String eventDate, String eventVenue, String eventDescription){
this.eventName = eventName;
this.eventDate = eventDate;
this.eventVenue = eventVenue;
this.eventDescription = eventDescription;
}
public String geteventName() {
return eventName;
}
public void seteventName(String eventName) {
this.eventName = eventName;
}
public String geteventDate() {
return eventDate;
}
public void seteventDate(String eventDate) {
this.eventDate = eventDate;
}
public String geteventVenue() {
return eventVenue;
}
public void seteventVenue(String eventVenue) {
this.eventVenue = eventVenue;
}
public String geteventDescription() {
return eventDescription;
}
public void seteventDescription(String eventDescription) {
this.eventDescription = eventDescription;
}

This looks wrong:
Query query = db.collection("event").orderBy("ASC").limit(10);
You are telling Firestore to sort by a field called ASC, which doesn't exist in your screenshot, so no documents are returned.
You probably want to sort on the ascending date, which you can do with:
Query query = db.collection("event").orderBy("eventDate", Direction.ASCENDING).limit(10);
Note that while the above will fix the problem of the documents not showing, they will still show up in the wrong order. This is because your eventDate field is not useful for sorting dates.
Strings in Firestore are sorted lexicographically, and in that order, "12/7/2021" becomes before "13/6/2021".
If you want to fix this problem, you can either store the dates as Firestore's built-in Timestamp type, or use a string format that allows sorting, like "2021-07-12" (which is *after* "2021-07-13"`.

databasehelper CRUD function

I am a newbie to android studio and have replicated sample code samples to fit my application. The purpose is to read all my company records. I have tried a couple variations without success. The error I get indicates Customers() can not be applied to: with a list of the fields beneath. I have 12 tables with CRUD methods for each. The same error for all tables is the same.
I have all the individual table.java files built and want to finish all the CRUD functions without errors before moving on to the main activity.java file.
// Get All CompanyData =========================================================
public List<CompanyData> GetAllCompanyData() {
List<CompanyData> compdataList = new ArrayList<>();
String selectQuery = "SELECT * FROM " + TABLE_CompanyData;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
if (cursor.moveToFirst()) {
do {
CompanyData compdata;
compdata = new CompanyData();
compdata.setcompanyid(Long.parseLong(cursor.getString(0))); // <==============================================================
compdata.setcompanyname(cursor.getString(1));
compdata.setcompanyaddress1(cursor.getString(2));
compdata.setcompanyaddress2(cursor.getString(3));

How to work with Blob when trying to insert image into Sqlite database?

I am new in Android dev.
I am trying to create Android app with SQlite. I have a problem with inserting image in Blob. Text is easy to insert, but problem is with image. I know I need to use Blob, but question is, where to use it ? I need to use Imageview in my layout ?
I need to clic to image button, then insert image from SD card or mobile and then it save into Sqlite database with text. After it, retrive from Sqlite database.
Thank you for your attention and help.

Save images in database is not good practice (save in folder is more beautiful).
But... How converter image view in byte[]
image = (ImageView)findViewById(R.id.qrcode);
Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream);
byte[] image=stream.toByteArray();
Then save you image byte[] in dataBase.

For #Peterr
What is wrong here ?
btnSubmit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String name=etName.getText().toString();
String email=etEmail.getText().toString();
String roll=etRoll.getText().toString();
String address=etAddress.getText().toString();
String branch=etBranch.getText().toString();
image = (ImageView)findViewById(R.id.image); //error on image????
Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap(); //error on image ????
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream);
byte[] image=stream.toByteArray();
if(name.equals("") || email.equals("") || roll.equals("") ||address.equals("")||branch.equals("")){
Toast.makeText(MainActivity.this,"Please fill all the fields",Toast.LENGTH_LONG).show();
}else {
helpher = new DatabaseHelpher(MainActivity.this);
helpher.insertIntoDB(name, email, roll, address, branch, imageByteArray); //red is ImageByteArray ????
}
etName.setText("");
etRoll.setText("");
etAddress.setText("");
etBranch.setText("");
etEmail.setText("");
Toast.makeText(MainActivity.this, "insert value", Toast.LENGTH_LONG);
}
});

ImageView image = (ImageView)findViewById(R.id.image);
Is referent you ImageView component in XML layout.
In your second line of activity, you are declaring image EditText, this not is EditText, this is ImageView.

Steps :
obtain the image from image view.
convert image to byte array.
pass the byte array as data/parameter in your query for database

here is my arrays.xml

<item>Malicious Code</item>
<item>Spam</item>
<item>Intrusion</item>
<item>Not Sure</item>
</string-array>
</resources>

the form name is case sensitive.
use $_POST['gender'];
another thing is. where is your definition of $row? looks like it may be empty so you will not post any data.
enable error_reporting and display_errors while development help you to find such kind of errors much faster
another thing very important dont use mysql_* functions they are insecure and deprecated. have a look ad PDO instead
also use prepared statements and escape userinput.
