使用按钮单击我的活动课程

My activity class using button click

MainActivity.java

    import android.app.Activity;
    import android.content.Intent;
    import android.content.res.Configuration;
    import android.content.res.Resources;
    import android.os.Bundle;
    import android.os.Handler;
    import android.util.DisplayMetrics;
    import android.view.View;
    import android.view.Window;
    import android.widget.Button;
    import android.widget.SimpleAdapter;

    import java.util.Locale;

    public class SplashActivity extends Activity implements View.OnClickListener{

        // Splash screen timer
        private static int SPLASH_TIME_OUT = 3000;
        Button buttonEnglish,buttonArabic;


        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_splash);


            buttonEnglish =(Button) findViewById(R.id.buttonEnglish);
            buttonArabic =(Button) findViewById(R.id.buttonArabic);

            buttonEnglish.setOnClickListener(this);
            buttonArabic.setOnClickListener(this);

        }
        @Override
        public void onClick(View view) {
           switch(view.getId()) {
               case R.id.buttonEnglish:
                   MyApp.setLocaleEn(SplashActivity.this);
                   setLocale("en");
                   break;
               case R.id.buttonArabic: {
                   //buttonArabic.setBackground(getDrawable(R.color.white));
                   MyApp.setLocaleAr(SplashActivity.this);
                   setLocale("ar");
                   break;
               }
           }
        }
    }

推荐答案

只需忘记所有内容，只需实现以下代码段即可

Just forget everything and just implement the below code Snippet

在build.gradle文件中

Inside your build.gradle file

defaultConfig
 {
    resConfigs "en", "ar"
 }

在您的活动中:

 @Override
    public void onClick(View view) 
    {
       switch(view.getId()) 
       {
           case R.id.buttonEnglish:

               updateLanguage("en");

               break;
           case R.id.buttonArabic: 

                updateLanguage("ar");

               break;
       }
    }

@Override
public void recreate()
{
    if (android.os.Build.VERSION.SDK_INT >= 14)
    {
        super.recreate();
    }
    else
    {
        startActivity(getIntent());
        finish();
    }
}

private void updateLanguage(String language)
{
    Locale locale = new Locale(language);
    Locale.setDefault(locale);
    Configuration config = new Configuration();
    config.locale = locale;
    getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());

    SharedPreferences languagepref = getSharedPreferences("language",MODE_PRIVATE);
    SharedPreferences.Editor editor = languagepref.edit();
    editor.putString("languageToLoad",language);
    editor.apply();

    recreate();
}
