我希望我的应用程序支持三种语言西班牙语,葡萄牙语和英语.并选择在app中选择语言.我已经做了

1)3个可绘制的文件夹drawable-es,drawable-pt,drawable.

2)3个值文件夹值-es,values-pt,values.根据语言更改String.xml值.

我有imageView来选择语言.当点击它打开菜单包括选项英语,西班牙语,葡萄牙语.

我通过此代码在选项选择中在应用程序内设置Locale

public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.en:
             Locale locale = new Locale("en");

             config.locale = locale;
             getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
             Toast.makeText(this, "Locale in English !", Toast.LENGTH_LONG).show();

             Configuration config2 = new Configuration();
             config2.locale = locale2;
             getBaseContext().getResources().updateConfiguration(config2, getBaseContext().getResources().getDisplayMetrics());

             Toast.makeText(this, "Locale in Portugal !", Toast.LENGTH_LONG).show();
             break;

        case R.id.es:
             Locale locale3 = new Locale("es"); 
             Locale.setDefault(locale3);
             Configuration config3 = new Configuration();
             config3.locale = locale3;
             getBaseContext().getResources().updateConfiguration(config3, …
