如何更改语言？

Question

我已经在Alpha Google Play商店中发布了版本。

当时下载并更改语言时，我需要终止应用程序并再次打开以反映语言更改。

我要立即更改。

我该怎么做？

Answer 1

您需要重新开始活动。

 val intent = this.intent//this will get current activity intent
 this.finish() // this will finish current activity
 startActivity(intent) // And this will apply changes and restart activity

Answer 2

在此活动中使用微调器的更改值，它将应用于当前活动以反映在配置中所做的更改以刷新它。

演示代码：

public class AndroidLocalize extends Activity {
    Spinner spinnerctrl;
    Button btn;
    Locale myLocale;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        spinnerctrl = (Spinner) findViewById(R.id.spinner1);
        spinnerctrl.setOnItemSelectedListener(new OnItemSelectedListener() {

            public void onItemSelected(AdapterView<?> parent, View view,
                    int pos, long id) {

                if (pos == 1) {

                    Toast.makeText(parent.getContext(),
                            "You have selected Tamil", Toast.LENGTH_SHORT)
                            .show();
                    setLocale("ta");
                } else if (pos == 2) {

                    Toast.makeText(parent.getContext(),
                            "You have selected Hindi", Toast.LENGTH_SHORT)
                            .show();
                    setLocale("hi");
                } else if (pos == 3) {

                    Toast.makeText(parent.getContext(),
                            "You have selected English", Toast.LENGTH_SHORT)
                            .show();
                    setLocale("en");
                }

            }

            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub
            }

        });
    }

    public void setLocale(String lang) {

        myLocale = new Locale(lang);
        Resources res = getResources();
        DisplayMetrics dm = res.getDisplayMetrics();
        Configuration conf = res.getConfiguration();
        conf.locale = myLocale;
        res.updateConfiguration(conf, dm);
        Intent refresh = new Intent(this, AndroidLocalize.class);
        startActivity(refresh);
    }
}

我希望它能帮助您...！
