The way of changing string into different languages is called as localizationIn this chapter we will explain , how you can localize your application according to different regions e.t.c. We will localize the strings used in the application, and in the same way other things can be localized.
Localizing Strings
In order to localize the strings used in your application , make a new folder under res with name of values-local where local would be the replaced with the region.For example, in the case of italy, the values-it folder would be made under res. It is shown in the image below −
Italy, res/values-it/strings.xml
<;?xml version="1.0" encoding="utf-8"?> <resources> <string name="hello_world">Ciao mondo!</string> </resources>
Spanish, res/values-it/strings.xml
<;?xml version="1.0" encoding="utf-8"?> <resources> <string name="hello_world">Hola Mundo!</string> </resources>
French, res/values-it/strings.xml
<;?xml version="1.0" encoding="utf-8"?> <resources> <string name="hello_world">Bonjour le monde !</string> </resources>Apart from these languages, the region code of other languages have been given in the table below −
Sr.No | Language & code |
---|---|
1 | Afrikanns Code: af. Folder name: values-af |
2 | Arabic Code: ar. Folder name: values-ar |
3 | Bengali Code: bn. Folder name: values-bn |
4 | Czech Code: cs. Folder name: values-cs |
5 | Chinese Code: zh. Folder name: values-zh |
6 | German Code: de. Folder name: values-de |
7 | French Code: fr. Folder name: values-fr |
8 | Japanese Code: ja. Folder name: values-ja |
Example
To experiment with this example , you can run this on an actual device or in an emulator.Steps | Description |
---|---|
1 | You will use Android studio to create an Android application under a package com.example.sairamkrishna.myapplication. |
2 | Modify the res/layout/activity_main to add respective XML components |
3 | Modify the res/values/string.xml to add necessary string components |
4 | Run the application and choose a running android device and install the application on it and verify the results |
<?xml version="1.0" encoding="utf-8"?> <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:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"> <TextView android:text="Wifi" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/textview" android:textSize="35dp" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Tutorials point" android:id="@+id/textView" android:layout_below="@+id/textview" android:layout_centerHorizontal="true" android:textColor="#ff7aff24" android:textSize="35dp" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hindi" android:id="@+id/textView2" android:layout_below="@+id/textView" android:layout_centerHorizontal="true" android:layout_marginTop="50dp" android:textColor="#ff59ff1a" android:textSize="30dp" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/marathi" android:id="@+id/textView3" android:textSize="30dp" android:textColor="#ff67ff1e" android:layout_centerVertical="true" android:layout_centerHorizontal="true" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/arabic" android:id="@+id/textView4" android:layout_below="@+id/textView3" android:layout_centerHorizontal="true" android:layout_marginTop="42dp" android:textColor="#ff40ff08" android:textSize="30dp" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/chinese" android:id="@+id/textView5" android:layout_below="@+id/textView4" android:layout_alignLeft="@+id/textView3" android:layout_alignStart="@+id/textView3" android:layout_marginTop="42dp" android:textSize="30dp" android:textColor="#ff56ff12" android:layout_alignRight="@+id/textView3" android:layout_alignEnd="@+id/textView3" /> </RelativeLayout>Following is the content of the res/values/string.xml.
<resources> <string name="app_name">My Application</string> <string name="hello_world">Hello world!</string> <string name="action_settings">Settings</string> <string name="hindi">ట్యుటోరియల్స్ పాయింట్</string> <string name="marathi">शिकवण्या बिंदू</string> <string name="arabic">نقطة الدروس7</string> <string name="chinese">教程点</string> </resources>Let's try to run our application we just modified. I assume you had created your AVD while doing environment setup. To run the app from Android studio, open one of your project's activity files and click Run icon from the toolbar. Android studio installs the app on your AVD and starts it and if everything is fine with your setup and application, it will display following Emulator window −
