Activity Menu_main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item

        android:id="@+id/action_datapribadi"

        android:orderInCategory="100"

        android:showAsAction="never"

        android:title="Data Pribadi"/>

    <item

        android:id="@+id/action_jadwalkuliah"

        android:title="Jadwal Kuliah"/>

    <item

        android:id="@+id/action_logout"

        android:orderInCategory="100"

        android:showAsAction="never"

        android:title="Logout"/>

</menu>

Sekarang kita urus layout user interfacenya, edit file res/layout activity_main.xml

<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    tools:context=".MainActivity" >

    <TextView

        android:id="@+id/textViewHari"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentLeft="true"

        android:layout_alignParentTop="true"

        android:text=""

        android:textAppearance="?android:attr/textAppearanceMedium" />

    <ListView

        android:id="@+id/listViewJadwal"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_alignLeft="@+id/textViewHari"

        android:layout_below="@+id/textViewHari" >

    </ListView>

</RelativeLayout>

 Untuk layout baris pada list view pada directory layout buat file layout baru dengan nama row_jadwal.xml

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent" >

    <TextView

        android:id="@+id/textViewRowJam"

        android:layout_width="75dp"

        android:layout_height="wrap_content"

        android:layout_alignParentLeft="true"

        android:layout_alignParentTop="true"

        android:text="TextView" />

    <TextView

        android:id="@+id/textViewRowPelajaran"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentTop="true"

        android:paddingLeft="10dp"

        android:layout_toRightOf="@+id/textViewRowJam"

        android:text="TextView" />

</RelativeLayout>

Buat class baru dengan nama jadwal.java lalu ketikkan kode berkut

package com.agusharyanto.jadwalpelajaran;

public class Jadwal {

        public String hari="";

        public String jam="";

        public String pelajaran="";

        public Jadwal (String pday, String ptime, String plesson){

               this.hari = pday;

               this.jam = ptime;

               this.pelajaran = plesson;

        }

}

Buat Class baru dengan nama Adapter_jadwal.xml lalu ketikan kode berikut

package com.agusharyanto.jadwalpelajaran;

import java.util.ArrayList;

import android.app.Activity;

import android.content.Context;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ArrayAdapter;

import android.widget.TextView;

public class AdapterJadwal extends ArrayAdapter<Jadwal> {

    private Activity activity;

    private ArrayList<Jadwal> lJadwal;

    private static LayoutInflater inflater = null;

    public AdapterJadwal (Activity activity, int textViewResourceId,ArrayList<Jadwal> al_Jadwal) {

        super(activity, textViewResourceId, al_Jadwal);

        try {

            this.activity = activity;

            this.lJadwal = al_Jadwal;

            inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        } catch (Exception e) {

        }

    }

    public int getCount() {

        return lJadwal.size();

    }

    public long getItemId(int position) {

        return position;

    }

    public static class ViewHolder {

        public TextView jam;

        public TextView pelajaran;

    }

    public View getView(int position, View convertView, ViewGroup parent) {

        View vi = convertView;

        final ViewHolder holder;

        try {

            if (convertView == null) {

                vi = inflater.inflate(R.layout.row_jadwal, null);

                holder = new ViewHolder();

                holder.jam = (TextView) vi.findViewById(R.id.textViewRowJam);

                holder.pelajaran = (TextView) vi.findViewById(R.id.textViewRowPelajaran);

                vi.setTag(holder);

            } else {

                holder = (ViewHolder) vi.getTag();

            }

            holder.jam.setText(lJadwal.get(position).jam);

            holder.pelajaran.setText(lJadwal.get(position).pelajaran);

        } catch (Exception e) {

        }

        return vi;

    }

}

Edit main_activity.java lalu ketikkan kode berikut

package com.agusharyanto.jadwalpelajaran;

               setContentView(R.layout.activity_main);

               tvhari = (TextView) findViewById(R.id.textViewHari);

               listviewjadwal = (ListView) findViewById(R.id.listViewJadwal);

               initData();

        }

        public void initData() {

               list_jadwal.add(new Jadwal("Senin","08:00-10:00","Matematika"));

               list_jadwal.add(new Jadwal("Jumat","13:00-15:00","Logika Algoritma"));

        }

        @Override

               getMenuInflater().inflate(R.menu.main, menu);
