Android：如何检测手机设置中的语言变化

Android : how to detect language has been changes on phone setting(Android：如何检测手机设置中的语言变化)

问题描述

我如何检测我的手机语言是否已更改，就像Facebook应用程序一样，它将向我们发出通知：please wait, we preparing your language

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，会更加努力的。谢谢。

推荐答案

您可以使用：ACTION_LOCALE_CHANGED

这里有一个例子：

    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;
    }
