Code snippet:

private boolean mIs24HourFormat = false;

private TextView mTime;

MainActivity.java

@Overrideprotected void onCreate(Bundle savedInstanceState) {

    ......

    mIs24HourFormat = android.text.format.DateFormat.is24HourFormat(mContext);

    ....

    mTime.setText(getTime());

}

private String getTime() {
    DateFormat df = null;
    if(mIs24HourFormat){
        df = new SimpleDateFormat(mContext.getResources().getString(R.string.time_format_24hr), Locale.getDefault());
    } else{
        df = new SimpleDateFormat(mContext.getResources().getString(R.string.time_format_12hr), Locale.getDefault());
    }
    return df.format(Calendar.getInstance().getTime());
}

strings.xml

<string name="time_format_24hr" translatable="false">HH\uee01mm</string>
<string name="time_format_12hr" translatable="false">h\uee01mm</string>

Note:

If you want to show the time format followed by system, you can use android widget TextClock.
