StyledDialogs for Android

This library makes styling and using dialogs a piece of cake.

Screenshot of the dialogs

Features:

  • Compatible with Holo style and Android Design Guidelines
  • Change style for all dialogs only by changing a few color resources
  • Same look for Android 2.2+
  • Same API as native Android DialogFragments
  • SimpleDialogFragment class, which makes displaying simple dialogs a one line of code

How to include it in your project:

With Gradle:

compile 'eu.inmite.android.lib:android-styled-dialogs:1.1.2@aar'

With Maven:

<dependency>
    <groupId>eu.inmite.android.lib</groupId>
    <artifactId>android-styled-dialogs</artifactId>
    <version>1.1.2</version>
    <type>apklib</type>
</dependency>

Manually:

  • clone the project
  • add it as library project in your IDE
  • include latest support library

How to style all dialogs:

Add following into your application theme:

<item name="sdlDialogStyle">@style/DialogStyleLight.Custom</item>

or

<item name="sdlDialogStyle">@style/DialogStyleDark.Custom</item>

Define your dialog style, example for light theme:

<style name="DialogStyleLight.Custom">
    <!-- anything can be left out: -->
    <item name="titleTextColor">@color/dialog_title_text</item>
    <item name="titleSeparatorColor">@color/dialog_title_separator</item>
    <item name="messageTextColor">@color/dialog_message_text</item>
    <item name="buttonTextColor">@color/dialog_button_text</item>
    <item name="buttonSeparatorColor">@color/dialog_button_separator</item>
    <item name="buttonBackgroundColorNormal">@color/dialog_button_normal</item>
    <item name="buttonBackgroundColorPressed">@color/dialog_button_pressed</item>
    <item name="buttonBackgroundColorFocused">@color/dialog_button_focused</item>
    <item name="dialogBackground">@drawable/dialog_background</item>
</style>

How to create simple dialogs:

Easy:

Dialog with a simple message and Close button:

SimpleDialogFragment.createBuilder(this, getSupportFragmentManager()).setMessage(R.string.message).show();

Dialog with a title, message and Close button:

SimpleDialogFragment.createBuilder(this, getSupportFragmentManager()).setTitle(R.string.title).setMessage(R.string.message).show();

Dialog with a title, message and two buttons:

SimpleDialogFragment.createBuilder(this, getSupportFragmentManager()).setTitle(R.string.title).setMessage(R.string.message).setPositiveButtonText(R.string.positive_button).setNegativeButtonText(R.string.negative_button).show();

How to react on button press in your Activity/Fragment:

Simply implement interface ISimpleDialogListener in your Activity/Fragment. Listener's callbacks have requestCode parameter - you can use it if you have more dialogs in one Activity/Fragment. For Fragments use setTargetFragment() method in the builder.

How to react on cancelling the dialog:

Implement interface ISimpleDialogCancelListener in your Activity/Fragment.

How to create all other DialogFragments:

Extend BaseDialogFragment and look at demo app implementation. It shows two types of those implementations:

  • FavoriteCharacterDialogFragment shows a list in the dialog using extending BaseDialogFragment
  • JayneHatDialogFragment shows a custom view in the dialog using extending SimpleDialogFragment

Wishlist

The library could be improved with more common dialogs. Pull requests are encouraged!

Possible candidates:

  • date picker (spinners or calendar)
  • time picker
  • edittext dialog
  • password dialog
  • ...

Why 'Dialogs'?

Theodor Dialogs was a famous Czech painter, uncle of Jára Cimrman. Jára Cimrman was a playwright, philosopher, inventor, teacher, poet, mathematician and more but he lacked painting skills. That's why Theodor was helping him with many projects. Just like Android and this library do.
