Question

请帮帮我！我发现我的活动有问题我试图通过显示％s作为详细信息（信息）来创建一个警报活动。

我的活动

   mPreAlarm = getIntent().hasExtra(EXTRA_PRE_ALARM_FLAG) && getIntent().getBooleanExtra(EXTRA_PRE_ALARM_FLAG, true);
if (mPreAlarm) {
  String formatString = "%2$tl:%2$tM %2$tp %1$s";
  if (mSettings.getTimeFormatFor(0) == ReyTime.TIME_24) {
    formatString = "%2$tk:%2$tM %1$s";
  }
  mReyerName.setText(String.format(formatString, mReyerNameString, now));
} else {
  mReyerName.setText(getString(R.string.reyer_name_time, mReyerNameString));
}

mAlarmOff = (Button) findViewById(R.id.alarm_off);
mAlarmOff.setOnClickListener(this);

try {
  playAlarm();
} catch (Exception e) {
  Log.e("RingAlarmActivity", e.getMessage(), e);
}

//if(PermissionUtil.hasSelfPermission(this,  Manifest.permission.READ_PHONE_STATE)) {
  TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
  telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
//}

}

我的应用程序中的字符串

    <string name="rey_name_time">%s time.</string>

我的LogCat，我发现了一个错误，我无法修复

使用“字符串”时，需要使用“%s”，例如：

private String responseUser(User user) {
        return String.format("hello %s, your email %s and pass %s! (log: %s)",
                user.getName(),
                user.getEmail(),
                user.getPass(),
                user.result()
                );
    }

java.util.FormatFlagsConversionMismatchException：Conversion = s，Flags =
