}

```



### Step 2



Use the AndroidTagView in layout file, you can add customized attributes here.



```xml



```



### Step 3



Use TagView in your code.



```java

TagContainerLayout mTagContainerLayout = (TagContainerLayout) findViewById(R.id.tagcontainerLayout);

## Methods



* Set a ```TagView.OnTagClickListener``` for TagView, for ```onTagClick``` , ```onTagLongClick``` and ```onTagCrossClick``` callback

```java

mTagContainerLayout.setOnTagClickListener(new TagView.OnTagClickListener() {



    @Override

    public void onTagClick(int position, String text) {

        // ...

    }



    @Override

    public void onTagLongClick(final int position, String text) {

        // ...

    }



    @Override

    public void onSelectedTagDrag(int position, String text){

        // ...

    }

    

    @Override

    public void onTagCrossClick(int position) {

        // ...

    }

});

```

* Use ```setTagMaxLength(int max)``` to set text max length for all TagView.

```java

mTagContainerLayout.setTagMaxLength(int max);

```

* Use ```getTagText(int position)``` to get TagView text at the specified location.

```java

String text = mTagContainerLayout.getTagText(int position);

```

* ```getTags()``` return a string list for all tags in TagContainerLayout.

```java

List list = mTagContainerLayout.getTags();

```

* If you set the attribute ```container_enable_drag``` to ```true```, when drag the TagView you can get latest state by using ```getTagViewState()```. There are 4 state:```ViewDragHelper.STATE_IDLE```, ```ViewDragHelper.STATE_DRAGGING```, and ```ViewDragHelper.STATE_SETTLING```.

```java

int state = mTagContainerLayout.getTagViewState();

```

* Set the [theme](#themes). If you want to customize theme, remember set theme with ```ColorFactory.NONE``` first, then set other attributes.

```java

// Set library provides theme

mTagContainerLayout.setTheme(ColorFactory.PURE_CYAN);

```

```java

// Set customize theme

mTagContainerLayout.setTheme(ColorFactory.NONE);

mTagContainerLayout.setTagBackgroundColor(Color.TRANSPARENT);

```

* Set the text [direction](#directions). The library support two direction ```View.TEXT_DIRECTION_LTR``` and ```View.TEXT_DIRECTION_RTL```.

```java

mTagContainerLayout.setTagTextDirection(View.TEXT_DIRECTION_RTL);

```

* Use ```setTagTypeface(Typeface typeface)``` to set TagView text typeface.

```java

Typeface typeface = Typeface.createFromAsset(getAssets(), "iran_sans.ttf");

mTagContainerLayout.setTagTypeface(typeface);

```



**After set the attributes, set tags or add a tag.**



* Use ```setTags()``` to set tags, require a parameter of type ```List``` or ```String[]```.

```java

mTagContainerLayout.setTags(List tags);

```

* Insert a TagView into ContainerLayout at the end.

```java

mTagContainerLayout.addTag(String text);

```

* Insert a TagView into ContainerLayout at the specified location, the TagView is inserted before the current element at the specified location.

```java

mTagContainerLayout.addTag(String text, int position);

```

* Remove TagView on particular position, require the position of the TagView.

```java

mTagContainerLayout.removeTag(int position);

```

* Remove all TagViews.

```java

mTagContainerLayout.removeAllTags();

```

* Get a TagView in specified position.

```java

mTagContainerLayout.getTagView(int position);

```

* Set color for each TagView.

```java

List colors = new ArrayList();

//int[] color = {TagBackgroundColor, TabBorderColor, TagTextColor, TagSelectedBackgroundColor}

int[] color1 = {Color.RED, Color.BLACK, Color.WHITE, Color.YELLOW};

int[] color2 = {Color.BLUE, Color.BLACK, Color.WHITE, Color.YELLOW};

colors.add(color1);

colors.add(color2);

mTagcontainerLayout.setTags(tags, colors);

```
