dependencies {
    compile 'co.lujun:androidtagview:1.1.4'
}

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.

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 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}
int[] color1 = {Color.RED, Color.BLACK, Color.WHITE};
int[] color2 = {Color.BLUE, Color.BLACK, Color.WHITE};
colors.add(color1);
colors.add(color2);
mTagcontainerLayout.setTags(tags, colors);
