提问by Ivan
I've read a lot of posts about this, but I cannot get it to work. I need a textView (id - datumprikaz ) to show the current date like this: 28.11.2016.
我已经阅读了很多关于此的帖子，但我无法让它发挥作用。我需要一个 textView (id - datumprikaz ) 来显示当前日期，如下所示：28.11.2016。
I've managed to add the date using this method in my java:
我已经设法在我的 java 中使用此方法添加日期：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView dateView = (TextView)findViewById(R.id.datumprikaz);
setDate(dateView);
}
public void setDate (TextView view){
String str = String.format("%tc", new Date());
view.setText(str);
}
The problem is I get as a result: Fri Oct 28 19:57:37 GMT

And I just need it to show the current date like 28.11.2016.

what you need is just customizing you date.Here is simple solution for your setDate method.
您需要的只是自定义您的日期。这是您的 setDate 方法的简单解决方案。
public void setDate (TextView view){
Date today = Calendar.getInstance().getTime();//getting date
SimpleDateFormat formatter = new SimpleDateFormat("dd.MM.yyyy");//formating according to my need
String date = formatter.format(today);
view.setText(date);
}
you can format a date in many, many different ways. Here are some of the most common custom date formats.
您可以通过许多不同的方式格式化日期。以下是一些最常见的自定义日期格式。
yyyy-MM-dd results in 2009-09-06
yyyyMMdd results in 20090906
EEE MMM dd hh:mm:ss yyyy results in Sun Sep 06 08:32:51 2009
yyyy-MM-dd 结果于 2009-09-06
yyyyMMdd 结果为 20090906
EEE MMM dd hh:mm:ss yyyy 结果于 Sun Sep 06 08:32:51 2009

你可以使用SimpleDateFormat
TextView textView = (TextView)findViewById(R.id.datumprikaz);
SimpleDateFormat dateFormatter = new SimpleDateFormat("dd.MM.yyyy", Locale.getDefault());
textView.setText(dateFormatter.format(trenutniDatum));

The built-in TextClock is very convenient for displaying formatted date/time information, without any need to attend to constantly updating the content of the TextView.
内置的 TextClock 非常方便地显示格式化的日期/时间信息，而无需关注不断更新 TextView 的内容。
<android.widget.TextClock
android:id="@+id/datumprikaz"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:format12Hour="dd.MM.yyyy"
android:format24Hour="@null"
/>
