如何在android中将数字转换为货币格式

import java.text.NumberFormat;
import java.util.Locale;

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        double amount = 12345.67;

        // 创建NumberFormat对象，并设置为货币格式
        NumberFormat currencyFormat = NumberFormat.getCurrencyInstance(Locale.getDefault());

        // 将数字格式化为货币格式的字符串
        String formattedAmount = currencyFormat.format(amount);

        // 输出结果
        Log.d("Currency Format", formattedAmount);
    }
}
