<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">


    <hakobastvatsatryan.DropdownTextView
        android:id="@+id/first_dropdown_text_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:title_font="@font/your-title-font"
        app:title_text="@string/your-title-text"
        app:title_text_color="@color/your-title-text-color"
        app:title_text_color_expanded="@color/your-title-text-color-expanded"
        app:title_text_size="@dimen/your-title-text-size"
        app:content_font="@font/your-font"
        app:content_padding="@dimen/your-content-padding"
        app:content_text="@string/your-content-text"
        app:content_text_color="@color/your-content-text-color"
        app:content_text_size="@color/your-content-text-size"
        app:link_text_color="@color/your-text-link-color"
        app:underline_link="isUnderlineVisible"
        app:arrow_drawable="@drawable/your-arrow-icon" comment="icon should be faced to the right"
        app:bg_drawable_regular="@drawable/your-regular-background"
        app:bg_drawable_expanded="@drawable/your-expanded-background"
        app:expand_duration="@integer/your-expand-duration"
        app:panel_padding="@dimen/your-panel-padding"/>

</LinearLayout>
```

```kotlin
val dropdown = DropdownTextView.Builder(this)
  .setTitleTextRes(R.string.your_title_text)
  .setTitleTextColorRes(R.color.your_title_text_color)
  .setTitleTextColorExpandedRes(R.color.your_title_text_color_expanded)
  .setTitleTextSizeRes(R.dimen.your_title_text_size)
  .setTitleFontRes(R.font.your_title_font)
  .setContentTextRes(R.string.your_content_text)
  .setContentTextColorRes(R.color.your_content_text_color)
  .setContentTextSizeRes(R.color.your_content_text_size)
  .setContentFontRes(R.color.your_content_text_font)
  .setContentPaddingRes(R.dimen.your_content_padding)
  .setHtmlContent(htmlText)
  .setHtmlContent(htmlText, handler)
  .setLinkTextColorRes(R.color.your_text_link_color)
  .setLinkUnderline(isUnderlineVisible)
  .setArrowDrawableRes(R.drawable.your_drawable_icon) // icon should be faced to the right
  .setRegularBackgroundDrawableRes(R.drawable.your_regular_background)
  .setExpandedBackgroundDrawableRes(R.drawable.your_expanded_background)
  .setPanelPaddingRes(R.dimen.your_panel_padding)
