Detailed Android Change app language mode implementation process _android

One, the effect chart

Second, describe

Change the language in the Android project, which works only for this app and does not work on the entire system

Third, the solution

(i) Layout files

<linearlayout 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:orientation= "vertical"
  android:padding= "20DP" >

  <textview
    android:layout_ Width= "Wrap_content"
    android:layout_height= "wrap_content"
    android:text= "@string/hellow"

  /> <button
    android:layout_width= "wrap_content"
    android:layout_height= "wrap_content"
    android:o nclick= "Changelanguage" 
    android:text= "language switching"/>

</LinearLayout>

(ii) mainactivity home page

Package com.example.chinesepage;

Import Java.util.Locale;
Import android.app.Activity;
Import android.content.Intent;
Import android.content.res.Configuration;
Import android.content.res.Resources;
Import Android.os.Bundle;
Import Android.util.DisplayMetrics;
Import Android.view.View;

Import Android.widget.Toast; public class Mainactivity extends activity {@Override protected void onCreate (Bundle savedinstancestate) {Super
    . OnCreate (Savedinstancestate);
  Setcontentview (R.layout.activity_main); /** * Click the button, change the language * * @param view */public void changelanguage (view view) {resources = g
    Etresources (); Configuration Configuration = Resources.getconfiguration ();  Gets the resource configuration if (Configuration.locale.equals (Locale.china)) {//Determines whether the current language is Chinese configuration.locale = locale.english; Sets the current language configuration to English} else {configuration.locale = Locale.china;//Set the current language configuration to Chinese} displaymetrics metrics =
    New Displaymetrics (); Resources.uPdateconfiguration (configuration, metrics); Update configuration file Sendbroadcast (new Intent ("language"));
Send the broadcast and reopen the activtiy to reinitialize the interface language after the broadcast is accepted. Intent Intent = new Intent (mainactivity.this, Mainactivity.class); Alternatively, you can jump directly to mainactivity//Intent.setflags (intent.flag_activity_no_animation);
    Remove the jump from the animation, so that the user does not seem to jump the feeling//startactivity (intent);
  Finish (); }
}

(iii) Changereceiver broadcast class

Package com.example.chinesepage;

Import Android.content.BroadcastReceiver;
Import Android.content.Context;
Import android.content.Intent;

/**
 * Custom Broadcast language changes restart activity
 * 
 * @author ASUS * */Public
class Changereceiver extends Broadcastreceiver {
  private Intent mintent;

  @Override public
  void onreceive (context, Intent Intent) {
    mintent = new Intent (context, Mainactivity.class);
    Mintent.addflags (intent.flag_activity_new_task);
    Context.startactivity (mintent);
  }

(iv) Create Values-en folders under Res, copy string.xml, and change the Chinese into English to achieve internationalization.

Values/strings.xml

<resources>

  <string name= "app_name" > Language switching </string>
  <string name= "Hello_world" > Hello, world!</string>
  <string name= "action_settings" > Settings </string>
  <string name= "Hellow" > Hello </string>

</resources>

Values-en/strings.xml

<resources>

  <string name= "app_name" >ChinesePage</string>
  <string name= "Hello_world" >hello world!</string>
  <string name= "action_settings" >Settings</string>
  < String Name= "Hellow" >Hellow</string>

</resources>

(v) Registration of broadcasts (don't forget this ~)

 <receiver android:name= "Com.example.chinesepage.ChangeReceiver" >
      <intent-filter>
        <action Android:name= "Language"/>
      </intent-filter>
    </receiver>

Summarize

The above is the details of the Android Change app language model of the implementation process of the entire content, I hope that the development of Android to help you, if there are questions welcome to the discussion.
