An easy-to-use dialog to add tooltips to your app with teh ability to point to specific screen locations and also highlight views on-screen.

Great for on-boarding, calling out new features, or simply calling out bits of UI.


  • Show a default dialog pop up banner
  • Align the dialog to a certain vertical location on screen
  • Point to a specific element on-screen
  • Highlight specific UI elements by letting them "peek through" a background shade

Gradle Setup

In your app's build.gradle add

repositories {
    maven { url '' }

dependencies {
    implementation 'com.github.kcrimi:ToolTipDialog:~1.1.4'

Note: the jitpack repository is not necessary if it already exists in allRepositories in the project's build.gradle.


The below are shown as called by an Activity


ToolTipDialog(this, this)
  .title("This is a basic dialog") // Define the title for the tooltip
  .content("This dialog will show at the top of the screen by default") // Body content 
  .subtitle("Subtitle for tooltip") // Subtitle on the tooltip
  .setToolTipListener(toolTipListener) // Define the listener for clicks on the tooltip
  .show() // Build and show the tooltip

Title, subtitle, and content text views are hidden unless you set the content for them.

If you wish to only use 1 line of text, you should prefer to use the title since this will be centered within the dialog box.

Vertically positioned

Great for underlining an element or section of you UI.

ToolTipDialog(this, this)
  .setYPosition(720) // Align the top of the dialog with this position on screen

Point to specific location

You can also point to a specific point on screen. Great for calling out buttons and improving discoverability of buried features.

ToolTipDialog(this, this)
  .pointTo(250, 720) // Point to the specific X,Y position on-screen

View the sample app for how to point to specific views.

Peek-through views

Draw a typical shade behind your dialog but let specific views peek through.

You can also add as many of these as you'd like

Custom styles

You can define a custom theme inheriting from ToolTipDialog, defining any of the following attributes for the styles you wish to override.

Eg changing fonts, colors, padding, margins, etc.

<style name="ToolTipDialogTheme.Custom">
        <item name="toolTipDialog.titleTextStyle">@style/custom_title_text</item>
        <item name="toolTipDialog.subtitleTextStyle">@style/custom_subtitle_text</item>
        <item name="toolTipDialog.bodyTextStyle">@style/custom_body_text</item>
        <item name="toolTipDialog.backgroundColor">@color/custom_background_color</item>
        <item name="toolTipDialog.dialogBoxStyle">@style/my_custom_dialog_box_style</item>

If you only want to make small tweaks, have your custom styles declare the stock styles as the parent.

Now you simply pass in this custom theme when creating a new ToolTipDialog

My view keeps saying it's at x:0, y:0, making the dialog to point to the wrong spot

You'll need to make sure that you let the system have time to inflate the layout or else the views won't have their proper sizes/dimenstions.

If you need to show the tooltip on an early lifecycle event like onCreate() or onViewCreated(), yout can usually solve this issue by adding an additional delay or, more reliably, adding a ViewTreeObserver.

contentView.viewTreeObserver.addOnGlobalLayoutListener(object: ViewTreeObserver.OnGlobalLayoutListener,
            ViewTreeObserver.OnGlobalFocusChangeListener {
            override fun onGlobalLayout() {
                // Show Dialog here
