安卓 : how to detect language has been changes on phone setting

Question

我如何检测我的手机语言是否已更改，例如 facebook 应用程序会通知我们:请稍等，我们正在准备您的语言

我在 onCreate() 中使用了 myString = Locale.getDefault().getDisplayLanguage();

在我的onCreate()

@Override
    public void onCreate(Bundle savedInstanceState) {
        String myString = Locale.getDefault().getDisplayLanguage();
        if(myString.equals("en"){
            ProgressDialog progressDialog = new ProgressDialog(getApplicationContext());
            progressDialog.setMessage("Please wait, we preparing your language");
            progressDialog.show();
            /*
            it will dismiss until the language has been prepared
             */
        }else{
            //do nothing
        }
    }
}

请给我建议，我还在学习中，会更加努力。谢谢。

您可以使用:ACTION_LOCALE_CHANGED

举个例子:

    private BroadcastReceiver mLangReceiver = null;

    protected BroadcastReceiver setupLangReceiver(){

        if(mLangReceiver == null) {

            mLangReceiver = new BroadcastReceiver() {

                @Override
                public void onReceive(Context context, Intent intent) {
                    // do what you want
                }

            };

            IntentFilter filter = new IntentFilter(Intent.ACTION_LOCALE_CHANGED);
            registerReceiver(mLangReceiver, filter);
        }

        return mLangReceiver;
    }
