DialogFragments modeled after the AOSP Clock and Calendar apps to improve UX for picking time, date, numbers, and other things.

Try out the sample application on Google Play.

Android-BetterPickers is presented as an Android library project. A standalone JAR is not possible due to the theming capabilities offered by the DialogFragments.

You can include this project by referencing it as a library project in Eclipse or ant. Note that to use this library, both it and your project must be compiled with Android 4.0 (API level 14) or newer, similar to ActionBarSherlock.

If you are a Maven user you can easily include the library by specifying it as a dependency:

<dependency>
  <groupId>com.doomonafireball.betterpickers</groupId>
  <artifactId>library</artifactId>
  <version>1.6.0</version>
  <type>aar</type>
</dependency>

If you are a Gradle user you can also easily include the library:

compile 'com.doomonafireball.betterpickers:library:1.6.0'

If you are bringing in the support library you may need to add an exclusion:

compile ("com.doomonafireball.betterpickers:library:1.6.0") {
    exclude group: 'com.android.support', module: 'support-v4'
}

You MUST manually add dependency to android-switch-backport

compile 'org.jraf:android-switch-backport:1.4.0@aar'

And as it not available on maven central add a new maven repository

maven {
    url "http://JRAF.org/static/maven/2"
}

There is a standalone Gradle demo here that may also help.

For a working implementation of this project see the sample/ folder.

1. Implement the appropriate Handler callbacks:

public class MyActivity extends Activity implements 
  DatePickerDialogFragment.DatePickerDialogHandler {

  @Override
  public void onCreate(Bundle savedInstanceState) {
    // ...
  }
  
  @Override
  public void onDialogDateSet(int year, int monthOfYear, int dayOfMonth) {
    // Do something with your date!
  }
}

2. Use one of the Builder classes to create a PickerDialog with a theme:

DatePickerBuilder dpb = new DatePickerBuilder()
    .setFragmentManager(getSupportFragmentManager())
    .setStyleResId(R.style.BetterPickersDialogFragment);
dpb.show();

For a demonstration of theming, see the sample/ folder.

You can use your own themes if you'd like to change certain attributes. BetterPickers currently allows for customization of the following attributes:

    bpDialogBackground       :: the drawable (preferably a 9-patch) used as a window background for the DialogFragment
    bpTextColor              :: the color (optionally state list) for all text in the DialogFragment
    bpDeleteIcon             :: the drawable (optionally state list) for the delete button
    bpCheckIcon              :: the drawable (optionally state list) for the check button in the DateDialogPicker
    bpKeyBackground          :: the drawable (optionally state list) for the keyboard buttons
    bpButtonBackground       :: the drawable (optionally state list) for the Set, Cancel, and Delete buttons
    bpDividerColor           :: the color used for the DialogFragment dividers
    bpKeyboardIndicatorColor :: the color used for the ViewPagerIndicator on the DateDialogPicker

1. Create your own custom theme in styles.xml:

<style name="MyCustomBetterPickerTheme">
    <item name="bpDialogBackground">@drawable/custom_dialog_background</item>
    <item name="bpTextColor">@color/custom_text_color</item>
    <item name="bpDeleteIcon">@drawable/ic_backspace_custom</item>
    <item name="bpCheckIcon">@drawable/ic_check_custom</item>
    <item name="bpKeyBackground">@drawable/key_background_custom</item>
    <item name="bpButtonBackground">@drawable/button_background_custom</item>
    <item name="bpDividerColor">@color/custom_divider_color</item>
    <item name="bpKeyboardIndicatorColor">@color/custom_keyboard_indicator_color</item>
</style>

2. Instantiate your DialogFragment using your custom theme:

DatePickerBuilder dpb = new DatePickerBuilder()
    .setFragmentManager(getSupportFragmentManager())
    .setStyleResId(R.style.MyCustomBetterPickerTheme);
dpb.show();
