Usage

Step 1

Add below dependency in your build.gradle file.

dependencies {
    implementation 'co.lujun:androidtagview:1.1.7'
    implementation 'androidx.appcompat:appcompat:1.0.1'
}

Step 2

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

<co.lujun.androidtagview.TagContainerLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="0dp"
    android:padding="10dp"
    app:container_enable_drag="false"
    app:horizontal_interval="10dp"
    app:vertical_interval="10dp"
    app:tag_clickable="true"
    app:tag_theme="pure_teal" />

Step 3

Use TagView in your code.

TagContainerLayout mTagContainerLayout = (TagContainerLayout) findViewById(R.id.tagcontainerLayout);
mTagContainerLayout.setTags(List<String> tags);

Now, you have successfully created some TagViews. The following will show some more useful features for you customize.

Attributes

You can set these attributes in layout file, or use setters(each attribute has get and set method) to set them.

Methods

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

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.

mTagContainerLayout.setTagMaxLength(int max);

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

String text = mTagContainerLayout.getTagText(int position);

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

List<String> 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.

int state = mTagContainerLayout.getTagViewState();

Set the theme. If you want to customize theme, remember set theme with ColorFactory.NONE first, then set other attributes.

// Set library provides theme
mTagContainerLayout.setTheme(ColorFactory.PURE_CYAN);

// Set customize theme
mTagContainerLayout.setTheme(ColorFactory.NONE);
mTagContainerLayout.setTagBackgroundColor(Color.TRANSPARENT);

Set the text direction. The library support two direction View.TEXT_DIRECTION_LTR and View.TEXT_DIRECTION_RTL.

mTagContainerLayout.setTagTextDirection(View.TEXT_DIRECTION_RTL);

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

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<String> or String[].

mTagContainerLayout.setTags(List<String> tags);

Insert a TagView into ContainerLayout at the end.

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.

mTagContainerLayout.addTag(String text, int position);

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

mTagContainerLayout.removeTag(int position);

Remove all TagViews.

mTagContainerLayout.removeAllTags();

Get a TagView in specified position.

mTagContainerLayout.getTagView(int position);

Set color for each TagView.

List<int[]> colors = new ArrayList<int[]>();
//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);
