I&#39;m trying to use the `DateTimeFormatter` API to show a specific time in a `TextView` but whenever I run my app whilst my device is set to either the Arabic or Bengali language, the time always seems to show western numerals for some reason. Is this intentional, or is there something that I need to do to fix this?

    class MainActivity : AppCompatActivity() {
        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
            setContentView(R.layout.activity_main)
    
            val localizedTimeFormatter = DateTimeFormatter.ofLocalizedTime(FormatStyle.SHORT)
    
            val timeOpen = LocalTime.of(9, 30)
            val timeClose = LocalTime.of(17, 15)
    
            tv_time.text = (timeOpen.format(localizedTimeFormatter) +
                    &quot;\n\n&quot; + timeClose.format(localizedTimeFormatter))
        }
    }

这是按设计进行的。`DateTimeFormatter` 的实例，即使是本地化的实例，除非明确另有指示，否则都使用西方/ASCII 数字。当您知道如何操作时，指示并不难：

```java
DateTimeFormatter localizedTimeFormatter = DateTimeFormatter
        .ofLocalizedTime(FormatStyle.SHORT)
        .withDecimalStyle(DecimalStyle.ofDefaultLocale());

LocalTime timeOpen = LocalTime.of(9, 30);
LocalTime timeClose = LocalTime.of(17, 15);

String text = timeOpen.format(localizedTimeFormatter)
        + '\n' + timeClose.format(localizedTimeFormatter);
System.out.println(text);

孟加拉语区域 (bn-BD) 的输出：

৯:৩০ AM
৫:১৫ PM

而在阿拉伯语区域 (ar) 中：

٩:٣٠ ص
٥:١٥ م

我希望您能够自行从我的 Java 代码中进行翻译。我相信这不应该很难。

	DateTimeFormatter localizedTimeFormatter = DateTimeFormatter
			.ofLocalizedTime(FormatStyle.SHORT)
			.withDecimalStyle(DecimalStyle.ofDefaultLocale());
	
	LocalTime timeOpen = LocalTime.of(9, 30);
	LocalTime timeClose = LocalTime.of(17, 15);
	
	String text = timeOpen.format(localizedTimeFormatter)
			+ '\n' + timeClose.format(localizedTimeFormatter);
	System.out.println(text);
