- 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" > <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_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:id="@+id/title" 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:id="@+id/mk" android:layout_width="fill_parent" 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.
