AlertDialogPro
Why AlertDialogPro?
Theming Android's AlertDialog is not an easy thing. Because some of its attributes are not avaliable on old platform. Even on newer you still can't use android:layout to specify your own layout, since your views' ids should be consistant with Android's, some of which are not public... AlertDialogPro can make theming a lot easier.
Structure
alertdialogpro-core
Contains core codes for building an AlertDialogPro. Most of it's codes are ported from the latest Android Platform. It doesn't contain any resource file. If you want to implement a brand new theme, use this project directly. Otherwise, you should use alertdialogpro-theme-material or alertdialogpro-theme-holo.
alertdialogpro-theme-material
Based on alertdialogpro-core, gives AlertDialogPro a Material theme.
alertdialogpro-theme-holo (Obsolete)
Also based on alertdialogpro-core, gives AlertDialogPro a Holo theme.
Quick Start
Take alertdialogpro-theme-material for example.
Download
Grab latest version via Gradle:
dependencies {
compile 'com.github.fengdai:alertdialogpro-theme-material:0.2.6'
}
or Maven:
<dependency>
<groupId>com.github.fengdai</groupId>
<artifactId>alertdialogpro-theme-material</artifactId>
<version>0.2.6</version>
</dependency>
Specify AlertDialogPro's theme
In your app's xml file, use attribute alertDialogProTheme to specify your AlertDialogPro's theme. alertdialogpro-theme-material contains two built-in theme: Theme.AlertDialogPro.Material and Theme.AlertDialogPro.Material.Light. Here, we use the light version:
<style name="YourAppTheme">
...
<item name="alertDialogProTheme">@style/Theme.AlertDialogPro.Material.Light</item>
</style>
Build an AlertDialogPro
Use AlertDialogPro.Builder to build an AlertDialogPro:
AlertDialogPro.Builder builder = new AlertDialogPro.Builder(getContext());
builder.setIcon(R.drawable.icon).
setTitle("Title").
setMessage("Message Body").
setNeutralButton("Neutral", null).
setPositiveButton("Positive", null).
setNegativeButton("Negative", null).
show();
With the example codes above, you can create an AlertDialogPro which has an icon, a title, a message body and three option buttons. Look into the sample to see more usages.
Flavor built-in themes
Built-in themes can't meet your requirement? There are several attributes that you can use to make some slight changes. Here is an example to show how to change the positive button's color:
- Define your positive button's style:
<style name="YourButtonStyle" parent="Widget.AlertDialogPro.Material.Light.Button">
<item name="android:textColor">@color/adp_positive_button_color</item>
</style>
- Specify button style to your AlertDialogPro's theme with attribute
adpButtonBarPositiveButtonStyle:
<style name="FlavoredMaterialLight" parent="Theme.AlertDialogPro.Material.Light">
...
<item name="adpButtonBarPositiveButtonStyle">@style/YourButtonStyle</item>
</style>
- Use it in your app's theme:
<item name="alertDialogProTheme">@style/FlavoredMaterialLight</item>
Look into here to see all attributes.
Advanced customization
You can specify your own layout to AlertDialogPro. This can be very useful when you want to use custom views or you want a special dialog layout. Remember to keep your views' ids consistant with AlertDialogPro's ids.
- Define your AlertDialogPro's style:
<style name="YourAlertDialogProStyle" parent="AlertDialogPro.Material.Light">
<!-- Specify your AlertDialogPro's layout -->
<item name="adpLayout">@layout/your_alert_dialog</item>
<!-- Specify your AlertDialogPro's ListView layout. -->
<item name="adpListLayout">@layout/your_list_layout</item>
<!-- Specify your AlertDialogPro's list item layout. -->
<item name="adpListItemLayout">@layout/your_dialog_item</item>
<!-- Specify your AlertDialogPro's multi choice list item layout. -->
<item name="adpMultiChoiceItemLayout">@layout/your_multichoice_dialog_item</item>
<!-- Specify your AlertDialogPro's single choice list item layout. -->
<item name="adpSingleChoiceItemLayout">@layout/your_singlechoice_dialog_item</item>
</style>
- And add it to your AlertDialogPro's theme:
<style name="YourAlertDialogProTheme" parent="Theme.AlertDialogPro.Material.Light">
...
<item name="alertDialogProStyle">@style/YourAlertDialogProStyle</item>
</style>
- Use your AlertDialogPro theme in your app's theme:
<item name="alertDialogProTheme">@style/YourAlertDialogProTheme</item>
Migrate From AlertDialog
AlertDialogPro's Java API is exactly the same as AlertDialog's. In fact, most of AlertDialogPro's codes are ported from the latest AlertDialog. So the only thing you need to do in your Java codes is replacing AlertDialog.Builder with AlertDialogPro.Builder.
Requirements
AlertDialogPro requires at minimum Android 2.1 (API level 7).
