Tutorialwing Android Dynamic TimePicker Output

Getting Started

At first, we will create an android application. Then, we will use timePicker widget in the application.

1. Creating New Project

Follow the steps below to create a new project. Please ignore the steps if you have already created a new project.

Step Description
1. Open Android Studio.
2. Go to File => New => New Project. Write application name as DynamicTimePicker. Then, click next button.
3. Select minimum SDK you need. However, we have selected 17 as minimum SDK. Then, click next button
4. Then, select Empty Activity => click next => click finish.
5. If you have followed above process correctly, you will get a newly created project successfully. However, you can also visit post to create a new project to know steps in detail.

Now, we will modify xml and java file to use android timePicker programmatically.

2. Modify values folder

Open res/values/strings.xml file and add below code into it.

	<string name="app_name">DynamicTimePicker</string>
	<string name="selected_time">The selected time is:</string>

3. Modify Layout Folder

Open res/layout/activity_main.xml file. Then, add below code into it.

<?xml version="1.0" encoding="utf-8"?>





In activity_main.xml file, we have defined textView and linearLayout, with id rootContainer, that will act as container for the timePicker widget created programmatically.

4. Create Android TimePicker Programmatically / Dynamically

Open app/src/main/java/com.tutorialwing.dynamictimepicker/ file and add below code into it.

package com.tutorialwing.dynamictimepicker;

import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.TimePicker;

public class MainActivity extends AppCompatActivity {

	protected void onCreate(Bundle savedInstanceState) {

		final TextView textView = findViewById(;

		TimePicker timePicker = new TimePicker(this);
		LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
		layoutParams.setMargins(20, 20, 20, 20);
		timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
			public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {

				String format = "";
				if (hourOfDay == 0) {
					hourOfDay += 12;
					format = "AM";
				} else if (hourOfDay == 12) {
					format = "PM";
				} else if (hourOfDay > 12) {
					hourOfDay -= 12;
					format = "PM";
				} else {
					format = "AM";

				if (textView != null) {
					String hour = String.valueOf(hourOfDay < 10 ? "0" + hourOfDay : hourOfDay);
					String min = String.valueOf(minute < 10 ? "0" + minute : minute);

					String text = getString(R.string.selected_time) + " " + hour + " : " + min + " " + format;

		LinearLayout linearLayout = findViewById(;
		if (linearLayout != null) {

We have created android timePicker programmatically in java file (i.e. file). Then, we have set layout params and margins. Then, we have set time change listener in timePicker. Whenever we change time in timePicker, selected time will be displayed in textView. At last, we have set this timePicker in linearLayout having id rootContainer.

Since AndroidManifest.xml file is very important in any android project. We are also going to see the content inside this file.

AndroidManifest.xml file

Code inside src/main/AndroidManifest.xml file would look like below –

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.tutorialwing.dynamictimepicker"

		<activity android:name=".MainActivity">
				<action android:name="android.intent.action.MAIN"/>

				<category android:name="android.intent.category.LAUNCHER"/>


When we run the application, we will get output as shown above.

That’s the end of tutorial on Creating Android TimePicker Programmatically.
