Android TimePicker with Examples

In android, TimePicker is a widget for selecting the time of day, in either 24-hour or AM/PM mode.

If we use TimePicker in our application, it will ensure that the users will select a valid time for the day.

Following is the pictorial representation of using a timepicker control in android applications.

Generally, in android TimePicker available in two modes, one is to show the time in clock mode and another one is to show the time in spinner mode.

Create Android DatePicker in XML Layout File

In android, we can create a TimePicker in XML layout file using <TimePicker> element with different attributes like as shown below

<TimePicker android:id="@+id/timePicker1"
    
android:layout_width="wrap_content"
    
android:layout_height="wrap_content" />
In anroid, the TimePicker supports a two types of modes, those are Clock and Spinner to show the date details in our application.

Android TimePicker with Clock Mode

We can define android TimePicker to show time in clock format by using TimePicker android:timePickerMode attribute.

Following is the example of showing the TimePicker in Clock mode.

<TimePicker android:id="@+id/timePicker1"
    
android:layout_width="wrap_content"
    
android:layout_height="wrap_content"
    
android:timePickerMode="clock" />
The above code will return the TimePicker like as shown below.

If you observe above result we got the TimePicker in clock mode to select time in Hours and Minutes based on our requirements.

Android TimePicker with Spinner Mode

If we want to show the TimePicker in spinner format like showing hours and minutes separately to select the time, then by using TimePicker android:timePickerMode attribute we can achieve this.

Following is the example of showing the TimePicker in spinner mode.

 <TimePicker
    
android:id="@+id/datePicker1"
    
android:layout_width="wrap_content"
    
android:layout_height="wrap_content"
    
android:timePickerMode="spinner"/>
The above code will return the TimePicker like as shown below

Android TimePicker Dialog in Spinner Mode Example Diagram

If you observe above result we got the TimePicker in spinner mode to select the time in Hours and Minutes.

We can change the TimePicker in spinner mode to AM / PM format instead of 24 Hours format by using setIs24HourView(true) method in Activity file like as shown below.

TimePicker picker=(TimePicker)findViewById(R.id.timePicker1);
picker.setIs24HourView(
true);
The above code will return the TimePicker like as shown below

Android TimePicker Dialog in Spinner Mode with AM / PM format Example Diagram

If you observe above result we got the TimePicker with AM / PM format in spinner mode to select the time separately by hours, minutes and AM/PM.

This is how we can use TimePicker in different modes based on our requirements in android applications.

Android TimePicker Control Attributes

Following are the some of commonly used attributes related to TimePicker control in android applications.

AttributeDescription
android:idIt is used to uniquely identify the control
android:timePickerModeIt is used to specify timepicker mode, either spinner or clock
android:backgroundIt is used to set the background color for date picker.
android:paddingIt is used to set the padding for left, right, top or bottom of date picker.

Android TimePicker Example

Following is the example of defining a one TimePicker control, one TextView control and one Button control in RelativeLayout to show the selected time in AM / PM format on Button click in android application.

Create a new android application using android studio and give names as TimePickerExample. In case if you are not aware of creating an app in android studio check this article Android Hello World App.

Now open an activity_main.xml file from \res\layout path and write the code like as shown below

activity_main.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="match_parent">
    <
TimePicker
        
android:id="@+id/timePicker1"
        
android:layout_width="wrap_content"
        
android:layout_height="wrap_content"
        
android:layout_centerHorizontal="true"
        
android:layout_marginTop="20dp" />
    <
Button
        
android:id="@+id/button1"
        
android:layout_width="wrap_content"
        
android:layout_height="wrap_content"
        
android:layout_below="@+id/timePicker1"
        
android:layout_marginTop="10dp"
        
android:layout_marginLeft="160dp"
        
android:text="Get Date" />
    <
TextView
        
android:id="@+id/textView1"
        
android:layout_width="wrap_content"
        
android:layout_height="wrap_content"
        
android:layout_below="@+id/button1"
        
android:layout_marginLeft="120dp"
        
android:layout_marginTop="10dp"
        
android:textStyle="bold"
        
android:textSize="18dp"/>
</
RelativeLayout>
If you observe above code we created a one TimePicker control, one TextView control and one Button control in XML Layout file.

Once we are done with creation of layout with required controls, we need to load the XML layout resource from our activity onCreate() callback method, for that open main activity file MainActivity.java from \java\com.tutlane.timepickerexample path and write the code like as shown below.

MainActivity.java

package com.tutlane.timepickerexample;import android.os.Build;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.TextView;import android.widget.TimePicker;
public class MainActivity extends AppCompatActivity {
    TimePicker 
picker;
    Button 
btnGet;
    TextView 
tvw;
    
@Override
    
protected void onCreate(Bundle savedInstanceState) {
        
super.onCreate(savedInstanceState);
        setContentView(R.layout.
activity_main);
        
tvw=(TextView)findViewById(R.id.textView1);
        
picker=(TimePicker)findViewById(R.id.timePicker1);
        
picker.setIs24HourView(true);
        
btnGet=(Button)findViewById(R.id.button1);
        
btnGet.setOnClickListener(new View.OnClickListener() {
            
@Override
            
public void onClick(View v) {
                
int hour, minute;
                String am_pm;
                
if (Build.VERSION.SDK_INT >= 23 ){
                    hour = 
picker.getHour();
                    minute = 
picker.getMinute();
                }
                
else{
                    hour = 
picker.getCurrentHour();
                    minute = 
picker.getCurrentMinute();
                }
                
if(hour > 12) {
                    am_pm = 
"PM";
                    hour = hour - 
12;
                }
                
else
                
{
                    am_pm=
"AM";
                }
                
tvw.setText("Selected Date: "+ hour +":"+ minute+" "+am_pm);
            }
        });
    }
}
If you observe above code we are calling our layout using setContentView method in the form of R.layout.layout_file_name in our activity file. Here our xml file name is activity_main.xml so we used file name activity_main and we are trying to show the selected time of TimePicker in AM / PM format on Button click.

Generally, during the launch of our activityonCreate() callback method will be called by android framework to get the required layout for an activity.

Output of Android TimePicker Example

When we run above example using android virtual device (AVD) we will get a result like as shown below.

Android TimePicker Dialog Example Result

If you observe above result, we are getting the time from TimePicker in AM / PM format when we click on Button in android application.

Now we will see another example of showing the TimePicker control on EditText click event and get the selected time value in android application.

Androd Show TimePicker on EditText Click Example

Following is the example of open or popup timepicker dialog when we click on EditText control and get the selected time value on Button click in android application.

Create a new android application using android studio and give names as TimePickerExample. In case if you are not aware of creating an app in android studio check this article Android Hello World App.

Now open an activity_main.xml file from \res\layout path and write the code like as shown below

activity_main.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="match_parent">
    <
EditText
        
android:id="@+id/editText1"
        
android:layout_width="wrap_content"
        
android:layout_height="wrap_content"
        
android:layout_marginLeft="100dp"
        
android:layout_marginTop="150dp"
        
android:ems="10"
        
android:hint="Enter Time" />
    <
Button
        
android:id="@+id/button1"
        
android:layout_width="wrap_content"
        
android:layout_height="wrap_content"
        
android:layout_below="@+id/editText1"
        
android:layout_marginLeft="100dp"
        
android:text="Get Date" />
    <
TextView
        
android:id="@+id/textView1"
        
android:layout_width="wrap_content"
        
android:layout_height="wrap_content"
        
android:layout_below="@+id/button1"
        
android:layout_marginLeft="100dp"
        
android:layout_marginTop="10dp"
        
android:textStyle="bold"
        
android:textSize="18dp"/>
</
RelativeLayout>
If you observe above code we created a one EditText control, one TextView control and one Button control in XML Layout file.

Once we are done with creation of layout with required controls, we need to load the XML layout resource from our activity onCreate() callback method, for that open main activity file MainActivity.java from \java\com.tutlane.timepickerexample path and write the code like as shown below.

MainActivity.java

package com.tutlane.timepickerexample;import android.app.TimePickerDialog;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.text.InputType;import android.view.View;import android.widget.Button;import android.widget.EditText;import android.widget.TextView;import android.widget.TimePicker;import java.util.Calendar;
public class MainActivity extends AppCompatActivity {
    TimePickerDialog 
picker;
    EditText 
eText;
    Button 
btnGet;
    TextView 
tvw;
    
@Override
    
protected void onCreate(Bundle savedInstanceState) {
        
super.onCreate(savedInstanceState);
        setContentView(R.layout.
activity_main);
        
tvw=(TextView)findViewById(R.id.textView1);
        
eText=(EditText) findViewById(R.id.editText1);
        
eText.setInputType(InputType.TYPE_NULL);
        
eText.setOnClickListener(new View.OnClickListener() {
            
@Override
            
public void onClick(View v) {
                
final Calendar cldr = Calendar.getInstance();
                
int hour = cldr.get(Calendar.HOUR_OF_DAY);
                
int minutes = cldr.get(Calendar.MINUTE);
                
// time picker dialog
                
picker new TimePickerDialog(MainActivity.this,
                        
new TimePickerDialog.OnTimeSetListener() {
                            
@Override
                            
public void onTimeSet(TimePicker tp, int sHour, int sMinute) {
                                
eText.setText(sHour + ":" + sMinute);
                            }
                        }, hour, minutes, 
true);
                
picker.show();
            }
        });
        
btnGet=(Button)findViewById(R.id.button1);
        
btnGet.setOnClickListener(new View.OnClickListener() {
            
@Override
            
public void onClick(View v) {
                
tvw.setText("Selected Time: "eText.getText());
            }
        });
    }
}
If you observe above code we are calling our layout using setContentView method in the form of R.layout.layout_file_name in our activity file. Here our xml file name is activity_main.xml so we used file name activity_main and we are trying to show the TimePicker on EditText click, get the selected date of EditText control on Button click.

Generally, during the launch of our activityonCreate() callback method will be called by android framework to get the required layout for an activity.

Output of Androd Show TimePicker on EditText Click Example

When we run above example using android virtual device (AVD) we will get a result like as shown below.

Androd Show TimePicker on EditText Click Example Result

If you observe above result, we are able to open the TimePicker on EditText click and showing the selected date value in EditText control and getting the EditText control value on Button click in android application.

This is how we can use TimePicker control in android applications to pick the time based on our requirements.
