2. Assalamualaykum..Wr…Wb..
Pada kesempatan kali ini kita akan mrmbahas tentang (ARRAY).
Array disini kita akan gunakan dalam penginputan data mahasiswa.
berikut design layout and source code nya.
a. Layout pertama.
<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:background="@drawable/unnamed"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TabWidget
android:id="@android:id/tabs"

3. 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"/>

4. <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="Matakuliah:"
android:textStyle="bold"/>
<EditText android:id="@+id/mk" />
</TableRow>
<Button
android:id="@+id/save"
android:layout_marginTop="40dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Save" />
</TableLayout>
</FrameLayout>
</LinearLayout>
</TabHost>
b. Layout kedua.

5. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="4px" >

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_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ellipsize="end"
android:gravity="center_vertical"
android:singleLine="true"
android:textStyle="bold" />
<TextView

android:layout_height="wrap_content"
android:layout_weight="1"
android:ellipsize="end"
android:gravity="center_vertical"
android:singleLine="true" />
</LinearLayout>
</LinearLayout>

12. Kesimpulan :
banyak cara untuk menggunakan array.. yang perlu kita perhatikan adalah konsep cara kerja
array, dan memahami dari setiap action sehingga kita bisa mengimplementasikannya ke
dalam subuah program android.
