Kali ini kita akan melanjutkan android socket client dengan menambahkan activity palindrome. Activity atau view ini akan digunakan untuk menangani fungsi polindrome yang bisa dihandle oleh server socket update.
Langsung saja, kita create Blank Activity lalu kita beri nama PalindromeActivity. Lalu akan terbentuk 2 file (java dan xml).
File “PalindromeActivity.java”

file “activity_palindrome.xml” yang berada di res/layout:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <EditText android:id="@+id/editText01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="" > </EditText> <Button android:id="@+id/myButton" android:layout_width="match_parent" android:layout_height="wrap_content" android:onClick="onClick" android:text="Send" > </Button> <TextView android:id="@+id/textView1" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="" /> </LinearLayout> |
Rubah file “AndroidManifest.xml” menjadi:
|
1 2 3 4 5 6 7 8 9 |
<activity android:name=".PalindromeActivity" android:label="@string/title_activity_palindrome" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> |
