Android studio tutorial retrieve data clock with TimePicker

In the previous android tutorial I have discussed about the following DatePicker in a simple application. In this article we will discuss how to retrieve data via TimePicker hour’s later change. For more details, we will immediately practice just to create a new project from the android studio and the project named TimePicker then you select Blank Activity. TimePicker Project consists of two main files of the first file for later layout which we give the name activity_main.xml and files to run a program that we named MainActivity.java.

Source Code activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">
    <Button
        android:id="@+id/btnGantiWaktu"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Klik untuk ubah waktu"/>
    <TextView
        android:id="@+id/lblWaktu"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Waktu sekarang: (jam:menit):"
        android:textAppearance="?android:attr/textAppearanceLarge"/>
    <TextView
        android:id="@+id/tvWaktu"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text=""
        android:textAppearance="?android:attr/textAppearanceLarge"/>
    <TimePicker
        android:id="@+id/timePicker1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="gone"/>
</LinearLayout>

        timePicker1 = (TimePicker) findViewById(R.id.timePicker1);
        final Calendar c = Calendar.getInstance();
        hour = c.get(Calendar.HOUR_OF_DAY);
        minute = c.get(Calendar.MINUTE);
        //mengeset tanggal sekarang ke textview
        lblWaktu.setText(new StringBuilder()
                .append(pad(hour)).append(":").append(pad(minute)));

            }
        });
    }

    @Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
            case TIME_DIALOG_ID:
                return new TimePickerDialog(this, timePickerListener,hour,minute,false);
        }
        return null;
    }

            = new TimePickerDialog.OnTimeSetListener(){

        public void onTimeSet(TimePicker view, int selectedHour,
                              int selectedMinute) {
            hour = selectedHour;
            minute = selectedMinute;
            lblWaktu.setText(new StringBuilder().append(pad(hour)).append(":").append(pad(minute)));

    };
    private static String pad(int c){
        if(c>=10)
            return String.valueOf(c);
        else
            return "0" + String.valueOf(c);
    }
}
