Time picker

 To implement a TimePicker in Android, you can use the `TimePicker` widget. Here's an example XML layout:

```xml

<TimePicker

    android:id="@+id/timePicker"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"/>

```

In your Java or Kotlin code, you can interact with the `TimePicker`:

```java

public class YourActivity extends AppCompatActivity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.your_layout);

        TimePicker timePicker = findViewById(R.id.timePicker);

        // If you want to use the 24-hour format, uncomment the following line:

        // timePicker.setIs24HourView(true);

        timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {

            @Override

            public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {

                // Handle the selected time

                String selectedTime = hourOfDay + ":" + minute;

                // Do something with the selected time

            }

        });

    }

}

```

In this example, the `TimePicker.OnTimeChangedListener` is used to listen for changes in the selected time. The `onTimeChanged` method is called when the user selects a new time. You can customize the code inside this method to perform actions based on the selected time.

Remember to replace `"your_layout"` with the actual name of your layout XML file.
