“Membuat Aplikasi Input Data Array"
Assalamulaikum, Wr. Wb.
Pada laporan kali ini saya akan membuat aplikasi Input data Array. Disini saya membuat Aplikasi android dengan menggunankan ADT.
- Membuat projek baru di editor yang akan kita gunakan seperti ADT, Android Studio, Dll.
File > New > Android Application Project dan beri nama pada aplikasi yang akan kita buat, contoh “Input Data”
- Disni file xml dengan nama “main” dan file java “Main_Activity”
- Main.xml
Script :
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="558dp"
android:background="@drawable/unnamed"
android:orientation="vertical" >
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="@+id/almag"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
<TableLayout
android:id="@+id/details"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="4px"
android:stretchColumns="1" >
<TableRow >
<TextView android:text="NIM :"
android:textStyle="bold"
/>
<EditText android:id="@+id/nim"
android:numeric="integer"/>
</TableRow>
<TableRow >
<TextView android:text="Nama:"
android:textStyle="bold"/>
<EditText android:id="@+id/nama" />
</TableRow>
<TableRow>
<TextView android:text="Jekel:"
android:textStyle="bold"/>
<RadioGroup android:id="@+id/jekel" >
<RadioButton
android:id="@+id/pria"
android:text="Pria" />
<RadioButton
android:id="@+id/perempuan"
android:text="Perempuan" />
</RadioGroup>
</TableRow>
<TableRow>
<TextView android:text="Jenis Barang:"
android:textStyle="bold"/>
<EditText android:id="@+id/mk" />

<Button

}
}
- Kemudian kita buat file baru dengan nama row.xml dan almag.java
- Script untuk row.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"

android:padding="4px" >
<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="true"
android:layout_marginRight="4px" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="@+id/l_nim"

android:layout_height="wrap_content"
android:layout_weight="1"
android:ellipsize="end"
android:gravity="center_vertical"
android:singleLine="true" />
</LinearLayout>
</LinearLayout>
- Script untuk almag.java
package com.riski.listharga;
public class almag {
private String nim = "";
private String nama = "";
private String matakuliah = "";
private String jekel = "";
public String getNim() {
return (nim);
}
public void setNim(String nim) {
this.nim = nim;
}
public String getNama() {
return (nama);
}
public void setNama(String nama) {
this.nama = nama;
}
public String getMatakuliah() {
return (matakuliah);
}
public void setMatakuliah(String matakuliah) {
this.matakuliah = matakuliah;
}
public String getJekel() {
return (jekel);
}
public void setJekel(String jekel) {
