TimePicker View
The TimePicker view enables users to select a time of the day, in either 24-hour mode or AM/PM mode.
Using the TimePicker View
1 . Modify the main.xml file located in the res/layout folder by adding the following lines in bold:
<?xmlversion=”1.0”encoding=”utf-8”?>
<LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android” android:orientation=”vertical”
android:layout_width=”fill_parent”
android:layout_height=”fill_parent”>
<TimePicker android:id=”@+id/timePicker”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content” />
<Button android:id=”@+id/btnSet”
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:text=”I am all set!” />
</LinearLayout>
2 . Add the following statements in bold to the MainActivity.java file:
package com.emergingandroidtech.TimePicker;
import android.app.Activity;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View;
import android.widget.Button;
import android.widget.TimePicker;
import android.widget.Toast;
public class MainActivity extends Activity
{
TimePicker timePicker;
/**Called when the activity is first created.*/
@Override public void onCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
timePicker = (TimePicker) findViewById(R.id.timePicker);
timePicker = (TimePicker) findViewById(R.id.timePicker);
timePicker.setIs24HourView(true);
//---Button view---
Button btnOpen = (Button) findViewById(R.id.btnSet);
btnOpen.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
Toast.makeText(getBaseContext(), “Time selected:” + timePicker.getCurrentHour() + “:” + timePicker.getCurrentMinute(), Toast.LENGTH_SHORT).show();
}
});
}
}
3 . This time, the TimePicker will be displayed in the 24-hour format. Clicking the Button will display the time that you have set in the TimePicker.
How It Works
The TimePicker displays a standard UI to enable users to set a time. By default, it displays the time in the AM/PM format. If you wish to display the time in the 24-hour format, you can use the setIs24HourView() method.
To programmatically get the time set by the user, use the getCurrentHour() and getCurrentMinute() methods:
Toast.makeText(getBaseContext(), “Timeselected:”+ timePicker.getCurrentHour() + “:”+timePicker.getCurrentMinute(), Toast.LENGTH_SHORT).show();
