Android Joda Time -如何从文件加载UTC

implementation 'joda-time:joda-time:2.10.10'

import org.joda.time.DateTime;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;

public class MainActivity extends AppCompatActivity {
    private static final String FILE_PATH = "/path/to/your/file.txt";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 获取文件路径
        File file = new File(FILE_PATH);

        // 读取文件内容
        String fileContent = readFile(file);

        // 解析UTC时间
        DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
        DateTime utcDateTime = formatter.parseDateTime(fileContent);

        // 打印UTC时间
        Log.d("UTC Time", utcDateTime.toString());
    }

    private String readFile(File file) {
        // 读取文件内容的逻辑
        // 返回文件内容的字符串形式
    }
}
