Visit GitHub RepoNumber Pickers



A customisable decimal and hexadecimal material picker view for Android.


Add the JitPack repository in your build.gradle at the end of repositories:

	allprojects {
		repositories {
			maven { url "" }

And add the dependencies

	dependencies {
	        implementation 'com.github.StephaneBg:SimpleNumberPicker:{latest-version}'
		implementation "$supportVersion"
		implementation "$constraintVersion"



To display a decimal picker DialogFragment:

        new DecimalPickerDialog.Builder()
                .setReference(REF_DEC_DIALOG) // Optional
                .setNatural(false) // Optional - false is default
                .setRelative(true) // Optional - true is default
                .setTheme( // Optional
                .show(getSupportFragmentManager(), TAG_DEC_DIALOG);


To display a hexadecimal picker DialogFragment:

        new HexaPickerDialog.Builder()
                .setReference(REF_HEX_DIALOG) // Optional
                .setMinLength(2) // Optional - Default is none
                .setMaxLength(8) // Optional - Default is none
                .setTheme( // Optional
                .show(getSupportFragmentManager(), TAG_HEX_DIALOG);


Your parent Activity or parent Fragment must implement DecimalPickerHandler or HexaPickerHandler.


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

    snpKeyColor              :: color of the keys
    snpNumberColor           :: color of the entered number
    snpBackspaceColor        :: color of the backspace button
    snpDialogBackground      :: color of the dialog background
  2. Create your own custom style in styles.xml:

  <style name="DecimalPickerTheme" parent="SimpleNumberPickerTheme">
      <item name="snpKeyColor">@android:color/white</item>
      <item name="snpNumberColor">@android:color/white</item>
      <item name="snpBackspaceColor">@android:color/white</item>
      <item name="colorAccent">@android:color/white</item>
      <item name="snpDialogBackground">@color/color_primary</item>

See sample for more details.
