Aplikasi Jadwal Kuliah

  Kali ini saya akan membuat aplikasi jadwal kuliah senin sampai jumat.

oke langsung saja kita mulai

pertama kita buat project kita dulu

Setelah ini kita buat main activity nya

2. Activity_main.xml (desain login)

<RelativeLayoutxmlns: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" >

    <LinearLayout

        android:id="@+id/linearLayout1"        

        android:layout_width="wrap_content"       

        android:layout_height="wrap_content"        

        android:layout_alignParentLeft="true"        

        android:layout_alignParentRight="true"        

        android:layout_alignParentTop="true" >

        <TextView

            android:id="@+id/textView1"            

            android:layout_width="match_parent"            

            android:layout_height="wrap_content"            

            android:gravity="center"            

            android:text="Form Login"

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

/>

    </LinearLayout>

    <LinearLayout

        android:id="@+id/linearLayout2"        

        android:layout_width="wrap_content"        

        android:layout_height="wrap_content"        

        android:layout_alignParentLeft="true"        

        android:layout_alignParentRight="true"        

        android:layout_below="@+id/linearLayout1"

        android:orientation="vertical" >

        <TextView

            android:id="@+id/textView2"            

            android:layout_width="match_parent"            

            android:layout_height="wrap_content"            

            android:text="User Name" />

        <EditText

            android:id="@+id/userNameEditText"

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            android:hint="User Name" >

            <requestFocus />

        </EditText>

    </LinearLayout>

    <LinearLayout

        android:id="@+id/linearLayout3"        

        android:layout_width="wrap_content"        

        android:layout_height="wrap_content"        

        android:layout_alignParentLeft="true"        

        android:layout_alignParentRight="true"        

        android:layout_below="@+id/linearLayout2"        

        android:orientation="vertical" >

        <TextView

            android:id="@+id/textView3"            

            android:layout_width="match_parent"            

            android:layout_height="wrap_content"            

            android:text="Password" />

        <EditText

            android:id="@+id/passwordEditText"

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            android:hint="Password"

            android:inputType="textPassword" />

    </LinearLayout>

    <LinearLayout

        android:layout_width="wrap_content"        

        android:layout_height="wrap_content"        

        android:layout_alignParentLeft="true"        

        android:layout_alignParentRight="true"        

        android:layout_below="@+id/linearLayout3" >

        <Button

            android:id="@+id/loginButton"            

            android:layout_width="wrap_content"            

            android:layout_height="wrap_content"            

            android:layout_weight="3"            

            android:text="Login" />

        <Button

            android:id="@+id/tutupButton"            

            android:layout_width="wrap_content"            

            android:layout_height="wrap_content"            

            android:layout_weight="1"            

            android:text="Tutup" />

    </LinearLayout>

    </RelativeLayout>

            Sekarang kita siapkan menu untuk aplikasi ini, masuk directory res/menu lalu edit main.xml

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

    <item

        android:id="@+id/action_senin"

        android:orderInCategory="100"

        android:showAsAction="never"

        android:title="Senin"/>

    <item

        android:id="@+id/action_selasa"

        android:orderInCategory="100"

        android:showAsAction="never"

        android:title="Selasa"/>

    <item

        android:id="@+id/action_rabu"

        android:orderInCategory="100"

        android:showAsAction="never"

        android:title="Rabu"/>

    <item

        android:id="@+id/action_kamis"

        android:orderInCategory="100"

        android:showAsAction="never"

        android:title="Kamis"/>

    <item

        android:id="@+id/action_jumat"

        android:orderInCategory="100"

        android:showAsAction="never"

        android:title="Jumat"/>

</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 res/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 AdapterJadwal.java lalu ketikan kode berikut

package com.rohmadpujiyanto.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 MainActivity.java lalu ketikkan kode berikut

               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

               // Inflate the menu; this adds items to the action bar if it is present.

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