   }
   public void close(){
   dbHelper.close();
   }
   public Barang createBarang(String nm,String mk,String hrg){
   ContentValues values=new ContentValues();
   values.put(dbHelper.COLOUMN_NAME, nm);
   values.put(dbHelper.COLOUMN_MERK, mk);
   values.put(dbHelper.COLOUMN_HARGA, hrg);
   
   long insertId=database.insert(dbHelper.TABLE_NAME,null, values);
   Cursor cursor=database.query(distinct, table, columns, selection, selectionArgs, groupBy, having, orderBy, limit, cancellationSignal)

Cara membuat ListView sederhana menggunakan  Layout standar yang disediakan oleh Android?

Bagaimana untuk mengikat objek ListView ListActivity untuk data "String []" menggunakan ArrayAdapter?

Tools:

Android Developer Tools (ADT) (atau Eclipse + ADT Plugin)

AVD Nexus S Android 4.3 "emulator" atau,

Min SDK 8

(1) Buat Aplikasi Android

File >> New >> Aplikasi Android

Masukkan nama App: android-sederhana-ListView

Pakcage:

 pilih defualt lain, berikutnya sampai Anda mencapai Finish

(2) Extend ListActivity

Satu-satunya file yang kita akan bekerja dengan adalah MainActivity.java "aktivitas kosong yang dihasilkan"

src / com / hmkcode / android / MainActivity.java

Tentukan array String "listItemArray" untuk menahan label masing-masing item daftar

Buat ArrayAdapter untuk mengikat data "String array" ke tampilan "android.R.layout.simple_list_item_1"

Panggilan setListAdapter (ArrayAdapter) melewati adaptor dibuat.

Penjelasan Coding:

import android.app.ListActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.ArrayAdapter;

import android.widget.ListView;

import android.widget.Toast;

public class MyListActivity extends ListActivity {

  public void onCreate(Bundle icicle) {

    super.onCreate(icicle);

    String[] values = new String[] { "Senin", "Selasa", "Rabu",

        "Kamis", "Jumat", “Sabtu", "Minggu" };

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,

        android.R.layout.simple_list_item_1, values);

    setListAdapter(adapter);

  }

  @Override

  protected void onListItemClick(ListView l, View v, int position, long id) {

    String item = (String) getListAdapter().getItem(position);

    Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();

  }

}

Pada coding :  String[] values = new String[] { "Senin", "Selasa", "Rabu",

        "Kamis", "Jumat", “Sabtu", "Minggu" };

Maka akan didefinisikan hari apa saja yang ada pada daftar listview.

Pada coding: protected void onListItemClick(ListView l, View v, int position, long id) {

    String item = (String) getListAdapter().getItem(position);

    Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();

Maka akan dibuat 1 method baru ketika List Item Di click akan muncul tulisan “selected” untuk penggantian tulisan dapat diganti dengan yang anda inginkan.
