Patio is a minimalistic Android view widget for selecting multiple images.

## Instructions

Patio can be added to an Activity or Fragment using the following XML

```XML
<com.andressantibanez.android.patio.Patio
  android:id="@+id/patio"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  app:thumbnailHeight="200dp"
  app:thumbnailWidth="200dp"
  app:thumbnailsContainerPadding="10dp"
  app:thumbnailsContainerBackground="#ddd"
  app:maxPictures="3"
  app:thumbnailsMessage="@string/patio_footer"
  app:actionsTextColor="#333"/>
```

Patio has certain customizable attributes:
- ***thumbnailHeight*** defines the thumbnails height.
- ***thumbnailWidth*** defines the thumbnails width.
- ***thumbnailsContainerPadding*** defines how much padding will be used for the thumbnails container.
- ***thumbnailsContainerBackground*** defines a background color for the thumbnails container.
- ***maxPictures*** specifies how many pictures can the user add to the Patio view.
- ***thumbnailsMessage*** defines a custom string for the views footer. This string can be used with %1$d and %2$d tokens to add a pictures attached / max pictures message.
- ***actionsTextColor*** defines the text color for each action: Take Picture, Attach Picture, Remove Picture, Clear.

To add this attributes you must add the following definition to the root view
```XML
xmlns:app="http://schemas.android.com/apk/res-auto"
```

Make sure the Activity or Fragment implements PatioCallbacks. In this callbacks we will handle ***startActivityForResult*** intent for adding pictures via Camera or Gallery. You can get these intents from `getTakePictureIntent()` or `getAttachPictureIntent()`.

***Callbacks***
```java
@Override
public void onTakePictureClick() {
    Intent intent = mPatio.getTakePictureIntent();
    startActivityForResult(intent, REQUEST_CODE_TAKE_PICTURE);
}

@Override
public void onAddPictureClick() {
    Intent intent = mPatio.getAttachPictureIntent();
    startActivityForResult(intent, REQUEST_CODE_ATTACH_PICTURE);
}
```
Also, make sure you register you register your Activity or Fragment to get notified when callbacks are fired.

***Listener***
```java
mPatio = (Patio) findViewById(R.id.patio);
mPatio.setCallbacksListener(this);
```

Patio needs the following permissions in your app in order to work properly.
```XML
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
```
To get an ArrayList of the pictures added to Patio you can call `getThumbnailsPaths()` method.
```java
ArrayList<String> thumbnails = mPatio.getThumbnailsPaths();
```
