Installation

1. Install:

   • Using npm: npm install react-native-dialogs --save
   • Using Yarn: yarn add react-native-dialogs

2. Link:

   • react-native link react-native-dialogs
   • Or if this fails, link manually using these steps

3. Compile application using react-native run-android

Manual Linking

Follow these steps if automatic linking (react-native link) failed.

1. In android/app/build.gradle, add the dependency to your app build:

   dependencies {
       ...
       compile project(':react-native-dialogs') // Add this
   }

2. In android/build.gradle, it should already be there, but in case it is not, add Jitpack maven repository to download the library afollestad/material-dialogs:

   allprojects {
       repositories {
           ...
           jcenter() // Add this if it is not already here
           ...
       }
   }

3. In android/settings.gradle:

   rootProject.name = ...
   ...
   include ':react-native-dialogs' // Add this
   project(':react-native-dialogs').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-dialogs/android') // Add this
   
   ...
   include ':app'

4. Import and add package, in android/app/src/main/.../MainApplication.java:

   ...
   import android.app.Application;
   ...
   
   import com.aakashns.reactnativedialogs.ReactNativeDialogsPackage; // Add new import
   
   ...
   
   public class MainApplication extends Application implements ReactApplication {
     ...
     @Override
     protected List<ReactPackage> getPackages() {
       return Arrays.<ReactPackage>asList(
         new MainReactPackage(),
         ...
         new ReactNativeDialogsPackage() // Add the package here
       );
     }
   }

Usage

1. Import it in your JS:

   import DialogAndroid from 'react-native-dialogs';

2. Call API:

   class Blah extends Component {
       render() {
           return <Button title="Show DialogAndroid" onPress={this.showDialogAndroid} />
       }
   
       showDialogAndroid = async () => {
           const { action } = await DialogAndroid.alert('Title', 'Message');
           switch (action) {
               case DialogAndroid.actionPositive:
                   console.log('positive!')
                   break;
               case DialogAndroid.actionNegative:
                   console.log('negative!')
                   break;
               case DialogAndroid.actionNeutral:
                   console.log('neutral!')
                   break;
               case DialogAndroid.actionDismiss:
                   console.log('dismissed!')
                   break;
           }
       }
   }

Examples

To see the examples redone with checkboxLabel see this PR - Github :: aakashns/react-native-dialogs - #86

Progress Dialog

DialogAndroid.showProgress('Downloading...', {
    style: DialogAndroid.progressHorizontal // omit this to get circular
});
setTimeout(DialogAndroid.dismiss, 5000);

Basic List

const { selectedItem } = await DialogAndroid.showPicker('Pick a fruit', null, {
    items: [
        { label:'Apple', id:'apple' },
        { label:'Orange', id:'orange' },
        { label:'Pear', id:'pear' }
    ]
});
if (selectedItem) {
    // when negative button is clicked, selectedItem is not present, so it doesn't get here
    console.log('You selected item:', selectedItem);
}

Radio List

Set positiveText to null for auto-dismiss behavior on press of a radio button item.

const { selectedItem } = await DialogAndroid.showPicker('Pick a fruit', null, {
    // positiveText: null, // if positiveText is null, then on select of item, it dismisses dialog
    negativeText: 'Cancel',
    type: DialogAndroid.listRadio,
    selectedId: 'apple',
    items: [
        { label:'Apple', id:'apple' },
        { label:'Orange', id:'orange' },
        { label:'Pear', id:'pear' }
    ]
});
if (selectedItem) {
    // when negative button is clicked, selectedItem is not present, so it doesn't get here
    console.log('You picked:', selectedItem);
}

Without auto-dismiss

Here we pass in a string to positiveText, this prevents the auto-dismiss on select of a radio item.

const { selectedItem } = await DialogAndroid.showPicker('Pick a fruit', null, {
    positiveText: 'OK', // this is what makes disables auto dismiss
    negativeText: 'Cancel',
    type: DialogAndroid.listRadio,
    selectedId: 'apple',
    items: [
        { label:'Apple', id:'apple' },
        { label:'Orange', id:'orange' },
        { label:'Pear', id:'pear' }
    ]
});
if (selectedItem) {
    // when negative button is clicked, selectedItem is not present, so it doesn't get here
    console.log('You picked:', selectedItem);
}

Checklist

const { selectedItems } = await DialogAndroid.showPicker('Select multiple fruits', null, {
    type: DialogAndroid.listCheckbox,
    selectedIds: ['apple', 'orange'],
    items: [
        { label:'Apple', id:'apple' },
        { label:'Orange', id:'orange' },
        { label:'Pear', id:'pear' }
    ]
});
if (selectedItems) {
    if (!selectedItems.length) {
        console.log('You selected no items.');
    } else {
        console.log('You selected items:', selectedItems);
    }
}

With clear list button

We can make the neutral button be a special button. Pressing it will clear the list and close the dialog. If you want this behavior, set neutralIsClear to true and also set neutralText to a string. Both of these properties must be set.

const { selectedItems } = await DialogAndroid.showPicker('Select multiple fruits', null, {
    type: DialogAndroid.listCheckbox,
    selectedIds: ['apple', 'orange'],
    neutralIsClear: true, /////// added this
    neutralText: 'Clear', /////// added this
    items: [
        { label:'Apple', id:'apple' },
        { label:'Orange', id:'orange' },
        { label:'Pear', id:'pear' }
    ]
});
if (selectedItems) {
    if (!selectedItems.length) {
        console.log('You selected no items.');
    } else {
        console.log('You selected items:', selectedItems);
    }
}

Prompt

const { action, text } = await DialogAndroid.prompt('Title - optional', 'Message - optional');
if (action === DialogAndroid.actionPositive) {
    console.log(`You submitted: "${text}"`);
}

HTML

DialogAndroid.alert('Title', `This is a link <a href="https://www.duckduckgo.com/">DuckDuckGo</a>`, {
    contentIsHtml: true
});

assignDefaults

You can set some defaults so you don't have to change it everytime.

DialogAndroid.assignDefaults({
    title: 'Default Title',
    positiveText: null,
    contentColor: 'rgba(0, 0, 0, 0.2)',
    widgetColor: 'blue'
})

Now any time you omit or pass undefined to contentColor, widgetColor, or title, it will use the defaults we assigned here.

DialogAndroid.alert(undefined, 'message here')

This will show title "Default Title", with no positive button, and the color of the message will be 20% black. If you did Dialog.showProgress, the progress indicator would be blue. etc.
