Date使用和xml中%1$s的适配

new Date().Format(“YYYY-mm-dd“)

const date = new Date();
date.toLocaleString('zh', { hour12: true });  //2018/4/4 下午6:57:36
date.toLocaleString('zh', { hour12: false });  //2018/4/4 18:57:36

界面上显示当前时间

    public String getCurrentTime() {
        Date mNow = new Date();
        SimpleDateFormat ft = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss.SSS");
        return ft.format(mNow);
    }
    
 String timeText = getResources().getString(R.string.current_time);
 tvTimeShow.setText(String.format(timeText, getCurrentTime()));

字符串填充

String title_name = “xxx”
textView.setText(String.format(getString(R.string.version_title), title_name ));
<string name="version_title">你好，我是%1$s：</string>
