I want to connect my application with an SQLite database. Whenever someone clicks on the create button, the database should be generated immediately. I'm using the onClick function, but I'm getting an error when the function is called. This is the code that is executed when the onClick function is called:
public void createDb(View view)
{
DataHandler db = new DataHandler(this);
db.addValue();
Toast.makeText(getApplicationContext(),"DataBase Created Successfully.", Toast.LENGTH_SHORT).show();
}
The function addValue is defined in the DataHandler class with the following code:
void addValue()
{
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values=new ContentValues();
Random rand=new Random();
//for (int i=0;i<15;i++)
{
values.put(KEY_VALUE,rand.nextInt(2));
db.insert(TABLE_DATA,null,values);
}
db.close();
return ;
}
I'm getting this error:

im learning about SQLite on Android Studio. Testing several times a created several tables on SQLite and now im trying validating a column and the tool "run" (that shows all process running back) and it shows a next error and then the app just crash:
E/SQLiteLog: (1) no such column...
I think is a error when i failed creating a table and now the code is trying reading a column on different table, i read about just unstalling a reinstalling the app on the emulator will fix the error, but it still appearing and crashing my app.
Sorry if this its too much obviously but im starting on this, thank you.
The code of the class where is the SQLite Data Base
Here is the name of the columns of the actual table
public class AdminSQLiteOpenHelper extends SQLiteOpenHelper {
public AdminSQLiteOpenHelper(#Nullable Context context, #Nullable String name, #Nullable SQLiteDatabase.CursorFactory factory, int version) {
super(context, name, factory, version);
}
#Override
public void onCreate(SQLiteDatabase DataBase) {
DataBase.execSQL("create table datos(nombre text primary key, contraseña text)");
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
}
}
I put just the class where the code is trying find the columns, i omitted the class where i registered data on the table, but ill put a image of the table.
public void Iniciar(View view) {
AdminSQLiteOpenHelper admin = new AdminSQLiteOpenHelper(this, "Registro", null, 1);
SQLiteDatabase BD1 = admin.getWritableDatabase();
String name = nombre.getText().toString();
String pass = contra.getText().toString();
if (!name.isEmpty() && !pass.isEmpty()) {
Cursor fila = BD1.rawQuery("select contraseña from datos where nombre =" + name, null);
if (fila.getString(1).equals(name) && fila.getString(2).equals(pass)) {
BD1.close();
Toast.makeText(this, "Hola", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "No se encontró el nombre de usuario o contraseña", Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(this, "No puede quedar ningún campo vacío", Toast.LENGTH_SHORT).show();
}
}
The full error
E/SQLiteLog: (1) no such column: David in "select contraseña from datos where nombre =David"

Try this. delete the database file already created on the emulator using Device File Explorer.
then use the following statement to create your table:
DataBase.execSQL("create table if not exists datos(id integer primary key autoincrement, nombre text, contraseña text)");
and then when you want to query, use this:
Cursor fila = BD1.rawQuery("select * from datos where nombre = '"+name+"'", null);
fila.moveToNext()

I couldn't spot where the error was!
Example : Find your view by id with view
EditText testttET = view.findViewById(R.id.testtt);
String text = testttET.getText().toString();
check if your text is not empty
if(!text.equals("")){
double value = Double.parseDouble(text);
}
I created the code below to get the contents of multiple EditText:
Integer data[] = new Integer[4];
ListView listView = (ListView) findViewById(R.id.listView);
for (i=0;i < listView.getCount();i++){
LinearLayout layout = (LinearLayout) listView.getChildAt(i);
EditText et = (EditText) layout.findViewById(R.id.record_list_edit);
data[i] = Integer.parseInt(et.getText().toString());
}
I can successfully use the following code to to get just the first number (or whichever one I want):
LinearLayout layout = (LinearLayout) listView.getChildAt(0);
EditText et = (EditText) layout.findViewById(R.id.record_list_edit);
data[0] = Integer.parseInt(et.getText().toString());
But when I use the for loop to get all, it breaks.
This is the error log:

Really thank you， Shaishav
Integer data[] = new Integer[listView.getCount()];
I know why I was wrong. I I counted the wrong number... I was so stupid...
The answer comes form Shaishav.
I have Firebase fully installed into Android Studio, and I've tested it with a couple 1 activity applications, but on the only application with more than one activity, it's not working.
When I try to do the following in my 'Sign up' code:
private void makeStudent(String email, String password) {
Student s = new Student(email, password);
Firebase ref = new Firebase("MYAPP.firebaseio.com/");
//took out my app name
Firebase studentlocation = ref.child("Student");
studentlocation.setValue(s); //this is the line on which I get the error
//also, when I go on my firebase site, it hasn't created the Student
//directory
}
The Firebase page said:
If your Android app has multiple activities, add this code to your Application Class. Otherwise add it in your main activity.
So, I looked around, and this is what I created:
I made a MyApplication.java file, which contained:
import com.firebase.client.Firebase;
public class MyApplication extends android.app.Application {
#Override
public void onCreate() {
super.onCreate();
Firebase.setAndroidContext(this);
}
}
Then I placed the following into AndroidManifest.xml:
android:name=".MyApplication"
Yet, I still receive an error on the exact same line.
How do I fix this Firebase issue? I appreciate any help I can get, please!

Possible source of error because it told me it couldn't obtain the Snapshot at the line in makeStudent(), but makeStudent() doesn't use Snapshot. Only userExists() does. Note: The variable 'exists' is defined as a static boolean in the SignUp class.
private boolean userExists() {
Firebase ref = new Firebase("MYAPPNAME.firebaseio.com");
ref.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot snapshot) {
for (DataSnapshot postSnapShot: snapshot.getChildren()) {
Student s = postSnapShot.getValue(Student.class);
if(s.getEmail().equals(mEmailView.getText().toString())) {
exists = true;
}
}
}
#Override
public void onCancelled(FirebaseError firebaseError) {
exists = true;
}
});
return exists;
}
SOLUTION TO MY ISSUE:
I realized that Snapshot was never used in makeStudent(), and that was where the error started. Thus, I looked in the only place it was used... userExists(), and it turned out that I was correct! The error was produced by trying to identify Student s as a nonexistent student! Thus, I actually needed a try like such:
private boolean userExists() {
Firebase ref = new Firebase("MYAPPNAME.firebaseio.com");
ref.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot snapshot) {
Student s;
for (DataSnapshot postSnapShot: snapshot.getChildren()) {
try {
s = postSnapShot.getValue(Student.class);
if(s.getEmail().equals(mEmailView.getText().toString())) {
System.out.println(snapshot.getValue());
exists = true;
}
} catch(Exception e) {
exists = false;
}
}
}
#Override
public void onCancelled(FirebaseError firebaseError) {
exists = true;
}
});
return exists;
}
Confusing title, I know, but not quite shure how to explain.
Will do my best here.
What I am trying to accomplish is that when user clicks a button, the text from one field is pushed to firebase, then the text from the next field is pushed below that.
Something like this:
-"UID"--"Scripttitle"--"ScriptURL"
Here is the code that I am trying to do this with:
final EditText title = (EditText) rlLayout.findViewById(R.id.inputScriptTitle);
final EditText scripturl = (EditText) rlLayout.findViewById(R.id.inputScriptURL);
final Button button = (Button) rlLayout.findViewById(R.id.submitScriptButton);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.push()
.child("scripttitle")
.setValue(title.getText().toString());
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.push()
.child(title.getText().toString())
.setValue(scripturl);
I am shure I am just doing some really basic error, but as I am new to programming, I cant really see what that might be.
The error from logcat is:

You can't set view to setValue. scripturl is a EditText.
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.push()
.child(title.getText().toString())
.setValue(scripturl);
if you use like that you don't see any error.
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.child(title.getText().toString())
.push()
.setValue(scripturl.getText().toString);
Replace your following code
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.push()
.child(title.getText().toString())
.setValue(scripturl);
with
new Firebase("https://theatre-assistant.firebaseio.com/scripts")
.push()
.child(title.getText().toString())
.setValue(scripturl.getText().toString());
//because you pass directly object in value method replace and pass data from edit text not object
