I have a problem with my code
package com.example.java;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.ListView;
import org.w3c.dom.Element;
import java.sql.Array;
import java.util.ArrayList;
import java.util.Arrays;
public class MainActivity3 extends AppCompatActivity {
private static final String Tag = "MainAcitivity3";
@override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main3);
Log.d(Tag, "onCreate: Started.");
ListView mListView = (ListView) findViewById(R.id.listView);
Intent intent = getIntent();
String asd = intent.getStringExtra(MainActivity2.namabarang);
String asdf = intent.getStringExtra(MainActivity2.jumlahstock);
Item sparepart = new Item(asd,asdf);
ArrayList[] itemlist = new ArrayList[1];
for(int i=0; i<2;i++)
{
itemlist
= new ArrayList<Item>(); // initialize each element with ArrayList object
}
itemlist[0].add(sparepart);
itemlist[1].add(sparepart);
PersonListAdapter adapter = new PersonListAdapter(this, R.layout.adapter_view_layout,itemlist[0]);
mListView.setAdapter(adapter);
String number = intent.getStringExtra(MainActivity2.extraint);
if(number != null) {
FrameLayout lay = (FrameLayout) findViewById(R.id.frames);
if (number.equals("1")) {
lay.setVisibility(View.INVISIBLE);
mListView.setVisibility(View.VISIBLE);
} else {
}
}
else{}
}
public void onBtnClick (View view){
Intent intent = new Intent(this,MainActivity2.class);
startActivity(intent);
}
}
And i plan to save the item in specific array in the arraylist and here is the error i got
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.java/com.example.java.MainActivity3}: java.lang.ArrayIndexOutOfBoundsException: length=1; index=1
