Example of Android TimePicker Widget

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

1. Creating New Project

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

Now, we will modify xml and java file to use timePicker widget in the application.

2. Modify Values folder

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

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

3. Use TimePicker Widget in xml file

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

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

	<TimePicker
		android:id="@+id/timePicker"
		android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:layout_marginLeft="40dp"
		android:layout_marginRight="40dp"
		android:layout_marginTop="5dp"/>

	<TextView
		android:id="@+id/textView"
		android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:layout_marginLeft="35dp"
		android:layout_marginTop="30dp"
		android:visibility="gone"/>

</LinearLayout>

In activity_main.xml file, we have defined timePicker and textView widgets. TextView will be used to show selected time in timePicker widget. Now, we will access these widgets in java file to perform some actions on it.

4. Access TimePicker Widget in java file

Open src/main/java/com.tutorialwing.timepicker/MainActivity.java file. Then, add below code into it.

package com.tutorialwing.timepicker;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.TextView;
import android.widget.TimePicker;

public class MainActivity extends AppCompatActivity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		getSelectedTime();
	}

	private void getSelectedTime() {
		final TextView textView = findViewById(R.id.textView);
		TimePicker timePicker = findViewById(R.id.timePicker);
		timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
			@Override
			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;
					textView.setText(text);
					textView.setVisibility(View.VISIBLE);
				}
			}
		});
	}
}

In MainActivity.java file, we have accessed textView and TimePicker widgets. Then, we have set a listener, time change listener, to get the time selected in timePicker widget. Then, we have shown the selected time in textView after some calculations. Calculation is just to show the time in proper format.

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

AndroidManifest.xml

Code inside src/main/AndroidManifest.xml file is as below –

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.tutorialwing.timepicker"
		  xmlns:android="http://schemas.android.com/apk/res/android">

	<application
		android:allowBackup="true"
		android:icon="@mipmap/ic_launcher"
		android:label="@string/app_name"
		android:roundIcon="@mipmap/ic_launcher_round"
		android:supportsRtl="true"
		android:theme="@style/AppTheme">
		<activity android:name=".MainActivity">
			<intent-filter>
				<action android:name="android.intent.action.MAIN"/>

				<category android:name="android.intent.category.LAUNCHER"/>
			</intent-filter>
		</activity>
	</application>

</manifest>

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

That’s end of tutorial on Android TimePicker widget.
