TextClock

TextClock can display the current date and/or time as a formatted string. This view honors the 24-hour format system setting.

As such, it is possible and recommended to provide two different formatting patterns: one to display the date/time in 24-hour mode and one to display the date/time in 12-hour mode. Most callers will want to use the defaults, though, which will be appropriate for the user's locale.

Code -

<TextClock
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    />

Java

LinearLayout layout1=(LinearLayout)findViewById(R.id.ll1);

TextClock textClock=new TextClock(this);

textClock.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT));

layout1.addView(textClock);

·         android:format24Hour="@null" .
