My problem right now is in printing the various elements that are inside an ArrayList that I created. The workings of my app are as follows:
- I use a Cursor, and I fetch the information from the table to the database.
- Then I pass in an ArrayList
So far so good, well save the information inside the ArrayList, the problem here is when it comes to the part where I print the elements, it just prints the first element to me.
I've used several solutions from the various questions of the same problem genre, but nothing solves it.
I leave below the parts of the code:
Fragment
package cakeparty.cakeparty.Fragments;
import android.content.Context;
import android.database.Cursor;
import android.database.DatabaseUtils;
import android.database.sqlite.SQLiteDatabase;
import android.net.Uri;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v4.app.ListFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import java.lang.reflect.Array;
import java.util.ArrayList;
import cakeparty.cakeparty.DB.MyDBHelper;
import cakeparty.cakeparty.Entidades.Bolo;
import cakeparty.cakeparty.Entidades.MyListAdapter;
import cakeparty.cakeparty.R;
public class to_Apresentar extends ListFragment {
private Context context;
private ArrayList<Bolo> arraylistBolo = new ArrayList<Bolo>();
private MyListAdapter myAdapter = null;
private String userLogado;
private Cursor cursor_bolos;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context = getActivity();
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
myAdapter = new MyListAdapter(context, arraylistBolo);
setListAdapter(myAdapter);
}
public void guardarInformacao(String user) {
this.userLogado = user;
}
@Override
public void onResume() {
super.onResume();
MyDBHelper dbHelper = new MyDBHelper(context);
SQLiteDatabase db = dbHelper.getWritableDatabase();
cursor_bolos = db.rawQuery("SELECT * FROM Bolo", null);
arraylistBolo.clear();
if (cursor_bolos != null && cursor_bolos.moveToFirst()) {
do {
arraylistBolo.add(new Bolo(cursor_bolos.getString(1), cursor_bolos.getString(5), cursor_bolos.getString(3), cursor_bolos.getString(2), cursor_bolos.getInt(4), cursor_bolos.getInt(7), cursor_bolos.getString(6), cursor_bolos.getString(8)));
} while (cursor_bolos.moveToNext());
}
myAdapter.notifyDataSetChanged();
cursor_bolos.close();
db.close();
}
MyListAdapter
package cakeparty.cakeparty.Entidades;
import android.content.Context;
import android.support.annotation.NonNull;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
import org.w3c.dom.Text;
import java.util.ArrayList;
import java.util.List;
import cakeparty.cakeparty.R;
/**

public class MyListAdapter extends ArrayAdapter<Bolo> {
private ArrayList<Bolo> resource;
private Context context;
public MyListAdapter(Context context, ArrayList<Bolo> resource) {
super(context, R.layout.linhaof_owncakes, resource);
this.resource = resource;
this.context = context;
}
@NonNull
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.linhaof_owncakes,parent, false);
TextView txtData = (TextView) v.findViewById(R.id.txtviewData);
TextView txtEstado = (TextView) v.findViewById(R.id.txtviewestado);
txtData.setText(resource.get(position).getDataEntrega());
int ex = resource.get(position).getEstado();
if(ex == 0) {
txtEstado.setText("Pendente");
}else {
if(ex == 1) {
txtEstado.setText("Em preparação");
}
}
}
return v;
}
}
XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_toLine"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/background"
android:orientation="horizontal"
>
<TextView
android:id="@+id/txtviewData"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="20dp"/>
<TextView
android:id="@+id/txtviewestado"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="40dp"
/>
</LinearLayout>
IMPORTANT NOTE:
I've already used a layout like this, but it just prints the first element.
<LinearLayout 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"
android:background="@drawable/background"
android:orientation="vertical">
<ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<TextView
android:id="@android:id/empty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="lista vazia"
/>
</LinearLayout>
Thank you for your understanding
