Time Picker Example Android

Time Picker Example is completely similar to Date Picker example except that we explicitly add 0 with single digit number

Here's the java code


public class TimePicker extends Activity {

private TextView mTimeDisplay;
private Button mPickTime;

private int mHour;
private int mMinute;

static final int TIME_DIALOG_ID = 0;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
      
     // capture our View elements
        mTimeDisplay = (TextView) findViewById(R.id.timeDisplay);
        mPickTime = (Button) findViewById(R.id.pickTime);

        // add a click listener to the button
        mPickTime.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                showDialog(TIME_DIALOG_ID);
            }
        });

        // get the current time
        final Calendar c = Calendar.getInstance();
        mHour = c.get(Calendar.HOUR_OF_DAY);
        mMinute = c.get(Calendar.MINUTE);

        // display the current date
        updateDisplay();
    }
  
    @Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
        case TIME_DIALOG_ID:
            return new TimePickerDialog(this,
                    mTimeSetListener, mHour, mMinute, false);
        }
        return null;
    }
  
 // updates the time we display in the TextView
    private void updateDisplay() {
        mTimeDisplay.setText(
            new StringBuilder()
                    .append(pad(mHour)).append(":")
                    .append(pad(mMinute)));
    }
  
 // the callback received when the user "sets" the time in the dialog
    private TimePickerDialog.OnTimeSetListener mTimeSetListener =
        new TimePickerDialog.OnTimeSetListener() {
     public void onTimeSet(android.widget.TimePicker view, int hourOfDay, int minute) {
                mHour = hourOfDay;
                mMinute = minute;
                updateDisplay();
            }





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

Your main.xml should look like this

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">

<TextView android:id="@+id/timeDisplay"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=""/>

<Button android:id="@+id/pickTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Change the time"/>

</LinearLayout>
