Show TimePicker with minutes intervals in android
Use the following the custom class called CustomTimePickerDialog, which I think solve your problem.
import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.List;
import android.app.TimePickerDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.widget.NumberPicker;
import android.widget.TimePicker;
public class CustomTimePickerDialog extends TimePickerDialog {
private final static int TIME_PICKER_INTERVAL = 5;
private TimePicker mTimePicker;
private final OnTimeSetListener mTimeSetListener;
public CustomTimePickerDialog(Context context, OnTimeSetListener listener,
int hourOfDay, int minute, boolean is24HourView) {
super(context, TimePickerDialog.THEME_HOLO_LIGHT, null, hourOfDay,
minute / TIME_PICKER_INTERVAL, is24HourView);
mTimeSetListener = listener;
}
@Override
public void updateTime(int hourOfDay, int minuteOfHour) {
mTimePicker.setCurrentHour(hourOfDay);
mTimePicker.setCurrentMinute(minuteOfHour / TIME_PICKER_INTERVAL);
}
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case BUTTON_POSITIVE:
if (mTimeSetListener != null) {
mTimeSetListener.onTimeSet(mTimePicker, mTimePicker.getCurrentHour(),
mTimePicker.getCurrentMinute() * TIME_PICKER_INTERVAL);
}
break;
case BUTTON_NEGATIVE:
cancel();
break;
}
}
@Override
public void onAttachedToWindow() {
super.onAttachedToWindow();
try {
Class<?> classForid = Class.forName("com.android.internal.R$id");
Field timePickerField = classForid.getField("timePicker");
mTimePicker = (TimePicker) findViewById(timePickerField.getInt(null));
Field field = classForid.getField("minute");
NumberPicker minuteSpinner = (NumberPicker) mTimePicker
.findViewById(field.getInt(null));
minuteSpinner.setMinValue(0);
minuteSpinner.setMaxValue((60 / TIME_PICKER_INTERVAL) - 1);
List<String> displayedValues = new ArrayList<>();
for (int i = 0; i < 60; i += TIME_PICKER_INTERVAL) {
displayedValues.add(String.format("%02d", i));
}
minuteSpinner.setDisplayedValues(displayedValues
.toArray(new String[displayedValues.size()]));
} catch (Exception e) {
e.printStackTrace();
}
}
}
Here is the demonstrating screenshot.
How to get 30 min interval in time picker in Android N
I have resolved my issue using this library and here is my complete code which may help someone in the future.
My complete code is in below.
public class MainActivity extends AppCompatActivity implements TimePickerDialog.OnTimeSetListener {
private TextView timeTextView;
private TimePickerDialog timePickerDialog;
private Button timeButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Find our View instances
timeTextView = findViewById(R.id.time_textview);
timeButton = findViewById(R.id.time_button);
// Show a timepicker when the timeButton is clicked
timeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Calendar now = Calendar.getInstance();
timePickerDialog = TimePickerDialog.newInstance(
MainActivity.this,
now.get(Calendar.HOUR_OF_DAY),
now.get(Calendar.MINUTE),
false
);
timePickerDialog.setThemeDark(false);
timePickerDialog.setTitle("TimePicker Title");
timePickerDialog.setTimeInterval(1, 30, 60);
timePickerDialog.setAccentColor(Color.parseColor("#9C27B0"));
timePickerDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialogInterface)
Log.d("TimePicker", "Dialog was cancelled");
}
});
timePickerDialog.show(getFragmentManager(), "Timepickerdialog");
}
});
}
@Override
public void onTimeSet(TimePickerDialog view, int hourOfDay, int minute, int second) {
updateEndTime(hourOfDay,minute);
}
private void updateEndTime(int hours, int mins) {
String timeSet = "";
if (hours > 12) {
hours -= 12;
timeSet = "PM";
} else if (hours == 0) {
hours += 12;
timeSet = "AM";
} else if (hours == 12) {
timeSet = "PM";
} else {
timeSet = "AM";
}
// Append in a StringBuilder
String aTime = new StringBuilder().append(pad(hours)).append(':')
.append(pad(mins)).append(" ").append(timeSet).toString();
timeTextView.setText(aTime);
}
private static String pad(int c) {
if (c >= 10)
return String.valueOf(c);
else
return "0" + String.valueOf(c);
}
@Override
public void onResume() {
super.onResume();
TimePickerDialog tpd = (TimePickerDialog) getFragmentManager().findFragmentByTag("Timepickerdialog");
if (tpd != null) tpd.setOnTimeSetListener(this);
}
}
My desire output is like this:
Android N,L and below timepicker with minute interval
Indeed creating my own timepicker was the solution. I'm posting my solution below for others. This creates a timepicker dialog with minute intervals for api 14 and above. It is working for intervals of 1,5 and 15. Other values may also work.
Usage:
Dialog intervalTimePickerDialog = IntervalTimePickerDialogFactory.getIntervalTimePickerDialog(Context context, int positiveTextId, TimePickerDialog.OnTimeSetListener callBack, int hourOfDay, int minute, boolean is24HourView, final int interval);
intervalTimePickerDialog .show();
I think it won't need much explanation. int positiveTextId can be removed, it was just something I needed.
timepickerdialog.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
