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;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

ListView listviewjadwal ;
@Override

super.onCreate(savedInstanceState);
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"));

@Override
public boolean onCreateOptionsMenu(Menu menu) {

getMenuInflater().inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
