### Installation

1. Install:
    - Using [npm](https://www.npmjs.com/#getting-started): `npm install react-native-dialogs --save`
    - Using [Yarn](https://yarnpkg.com/): `yarn add react-native-dialogs`

2. [Link](https://facebook.github.io/react-native/docs/linking-libraries-ios.html):
    - `react-native link react-native-dialogs`
    - Or if this fails, link manually using [these steps](#manual-linking)

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](https://github.com/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`:

   ```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:

   ```js
   import DialogAndroid from 'react-native-dialogs';
   ```

2. Call API:

   ```js
   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](https://github.com/aakashns/react-native-dialogs/pull/86#issuecomment-393408317)

#### Progress Dialog

![](https://github.com/aakashns/react-native-dialogs/blob/master/screenshots/progress-bar.png)
![](https://github.com/aakashns/react-native-dialogs/blob/master/screenshots/progress-circle.png)

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

#### Basic List

![](https://github.com/aakashns/react-native-dialogs/blob/master/screenshots/list.png)

```js
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

![](https://github.com/aakashns/react-native-dialogs/blob/master/screenshots/radiolist-autodismiss.gif)

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

```js
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

![](https://github.com/aakashns/react-native-dialogs/blob/master/screenshots/radiolist-nodismiss.gif)

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

```js
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

![](https://github.com/aakashns/react-native-dialogs/blob/master/screenshots/checklist.png)

```js
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

![](https://github.com/aakashns/react-native-dialogs/blob/master/screenshots/checklist-clear.png)

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.

```js
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

![](https://github.com/aakashns/react-native-dialogs/blob/master/screenshots/prompt.png)

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

#### HTML

![](https://github.com/aakashns/react-native-dialogs/blob/master/screenshots/html.png)

```js
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.

```js
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.

```js
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.
