# MaterialChipsInput

Implementation of Material Design [Chips](https://material.io/guidelines/components/chips.html) component for Android. The library provides two views : [`ChipsInput`](#chipsinput) and [`ChipView`](#chipview).

## Demo
[Download sample-v1.0.8.apk](https://github.com/pchmn/MaterialChipsInput/raw/master/docs/material-chips-input-sample-v1.0.8.apk)

## Setup

To use this library your `minSdkVersion` must be >= 15.

In your project level build.gradle :
```java
allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}       
```

In your app level build.gradle :
```java
dependencies {
    compile 'com.github.pchmn:MaterialChipsInput:1.0.8'
}      
```
<br><br>
## ChipsInput
This view implements the Material Design [Contact chips component](https://material.io/guidelines/components/chips.html#chips-contact-chips). 

It is composed of a collection of chips (`ChipView`) and an input (`EditText`). Touching a chip open a full detailed view (if non disable). The [GIF](#materialchipsinput) above describes the behavior of the `ChipsInput` view.

But everything is configurable (optional avatar icon, optional full detailed view, ...) so you can use the `ChipsInput` view for non contact chips.
### Basic Usage

#### XML
Use the ChipsInput view in your layout with default options  :

```xml
<com.pchmn.materialchips.ChipsInput
        android:id="@+id/chips_input"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:hint="Enter a name" />
```
You can also customize it ([see](#chipsinput-attributes) all attributes) :
```xml
<com.pchmn.materialchips.ChipsInput
        android:id="@+id/chips_input"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:hint="Enter a name"
        app:hintColor="@color/customColor"
        app:textColor="@color/customColor"
        app:maxRows="3"
        app:chip_labelColor="@color/customColor"
        app:chip_hasAvatarIcon="true"
        app:chip_backgroundColor="@color/customColor"
        app:chip_deletable="false"
        app:chip_deleteIconColor="@color/customColor"
        app:chip_detailed_textColor="@color/customColor"
        app:chip_detailed_backgroundColor="@color/customColor"
        app:chip_detailed_deleteIconColor="@color/customColor"
        app:filterable_list_backgroundColor="@color/customColor"
        app:filterable_list_textColor="@color/customColor" />
```

#### Suggestions
You can pass a `List<? extends ChipInterface>` object, which represents your suggestions, to the `ChipsInput` view, so it will work as a
`MultiAutoCompleteTextView` :

##### 1. Create a class that implements `ChipInterface` (or use directly the [`Chip`](https://github.com/pchmn/MaterialChipsInput/blob/master/library/src/main/java/com/pchmn/materialchips/model/Chip.java) class included in the library) :
```java
public class ContactChip implements ChipInterface {
    ...
}
```

##### 2. Then in your activity, or anything else, build your suggestion list of `ContactChip` (or `Chip`) and pass it to the `ChipsInput` view :
```java
// get ChipsInput view
ChipsInput chipsInput = (ChipsInput) findViewById(R.id.chips_input);

// build the ContactChip list
List<ContactChip> contactList = new ArrayList<>();
contactList.add(new ContactChip()); 
...

// pass the ContactChip list
chipsInput.setFilterableList(contactList);
```

#### Get the selected list
When you want you can get the current list of chips selected by the user :
```java
// get the list
List<ContactChip> contactsSelected = (List<ContactChip>) chipsInput.getSelectedChipList();
```

That's it, there is nothing more to do.

### Advanced Usage
#### ChipsListener
The `ChipsInput` view provides a listener to interact with the input :
```java
chipsInput.addChipsListener(new ChipsInput.ChipsListener() {
            @Override
            public void onChipAdded(ChipInterface chip, int newSize) {
                // chip added
                // newSize is the size of the updated selected chip list
            }

            @Override
            public void onChipRemoved(ChipInterface chip, int newSize) {
                // chip removed
                // newSize is the size of the updated selected chip list
            }

            @Override
            public void onTextChanged(CharSequence text) {
                // text changed
            }
        });
```

#### Add and remove chips manually
You don't have to pass a `List<? extends ChipInterface>` to the `ChipsInput` view and you can do the trick manually. Thanks to the `ChipsListener` you can be notified when the user is typing and do your own work.

```java
ChipsInput chipsInput = (ChipsInput) findViewById(R.id.chips_input);
```

##### Add a chip
There are multiple implementations :
```java
chipsInput.addChip(ChipInterface chip);
// or
chipsInput.addChip(Object id, Drawable icon, String label, String info);
// or
chipsInput.addChip(Drawable icon, String label, String info);
// or
chipsInput.addChip(Object id, Uri iconUri, String label, String info);
// or
chipsInput.addChip(Uri iconUri, String label, String info);
// or
chipsInput.addChip(String label, String info);
```

##### Remove a chip
There are multiple implementations :
```java
chipsInput.removeChip(ChipInterface chip);
// or
chipsInput.removeChipById(Object id);
// or
chipsInput.removeChipByLabel(String label);
// or
chipsInput.removeChipByInfo(String info);
```

After you added or removed a chip the `ChipsListener` will be triggered.

##### Get the selected list
When you want you can get the current list of chips selected by the user :
```java
// get the list
List<ChipInterface> contactsSelected = chipsInput.getSelectedChipList();
```
