Installation
------------

Install the npm package [`react-native-dialogs`](https://www.npmjs.com/package/react-native-dialogs). Inside your React Native project, run ([example](https://github.com/aakashns/react-native-dialogs-example/commit/e6b83bf3d2238cf7e4ec3688519f38b2544ccad5)):
```bash
rnpm install --save react-native-dialogs
```


In `android/app/build.gradle`, add a dependency to `':react-native-dialogs'` and URL of the Jitpack maven repository (to download the library https://github.com/afollestad/material-dialogs) :
```
repositories {
    maven { url "https://jitpack.io" }
}

```
The changes should look like [this](https://github.com/aakashns/react-native-dialogs-example/commit/b58086d8fb9ece99f0e678dd8bf0e689a856bd43).

Next, you need to change the `MainActivity` of your app to register `ReactNativeDialogsPackage` :
```java
import com.aakashns.reactnativedialogs.ReactNativeDialogsPackage;

    //...
public class MainActivity extends ReactActivity {
          //...

          @Override
          protected List<ReactPackage> getPackages() {
            return Arrays.<ReactPackage>asList(
                new MainReactPackage(),
                new ReactNativeDialogsPackage() // add this manager
            );
          }
}

```
See [this changelog](https://github.com/aakashns/react-native-dialogs-example/commit/52cac27756963bcd2f4fdcd039e1a78028bb0abd) for reference.

Now you're finally ready to start using module in your React Native application. See [this changelog](https://github.com/aakashns/react-native-dialogs-example/commit/2d8e02c22275479d2fbbb89f99dcb846834bec9d) for an example that uses `DialogAndroid`.

Usage
-----
```javascript
var DialogAndroid = require('react-native-dialogs');

var options = {
  title: 'Hello, World!',
  content: 'I\'m just simple Dialog',
  positiveText: 'OK',
  negativeText: 'Cancel'
};

var showDialog = function () {
  var dialog = new DialogAndroid();
  dialog.set(options);
  dialog.show();
}
```
Creation of a dialog works in 3 steps :
1. Create a new dialog using `new DialogAndroid()`.
2. Set some options using `dialog.set(options)`. `set` can be called multiple times, and options from multiple calls will be merged.
3. Show the dialog using `dialog.show()`.

This library is a thin wrapper over [afollestad/material-dialogs](https://github.com/afollestad/material-dialogs), which provides builders for showing Material Design dialogs in Android apps. The options provided to `set` map more or less directly to the methods provided in the original library. See [its documentation](https://github.com/afollestad/material-dialogs#basic-dialog) for reference.

The following options are currently supported (value type is `String` unless mentioned otherwise) :
