Material Tap Target Prompt
A Tap Target implementation in Android based on Material Design Onboarding guidelines. For more information on tap targets check out the guidelines.
JavaDocs, examples and a sample app with examples implemented are available.
The sample app is available to download on the Google Play Store: 
Quick start
Gradle
Add the following to build.gradle:
repositories {
jcenter()
}
dependencies {
implementation 'uk.co.samuelwall:material-tap-target-prompt:3.1.0'
}
Supports Android minSdkVersion 14
Version 2.15.0 works with Android Support Library
Also available from GitHub packages
Usage
Basic usage is shown below with more examples in the sample app and documentation:
new MaterialTapTargetPrompt.Builder(MainActivity.this)
.setTarget(R.id.fab)
.setPrimaryText("Send your first email")
.setSecondaryText("Tap the envelope to start composing your first email")
.setPromptStateChangeListener(new MaterialTapTargetPrompt.PromptStateChangeListener()
{
@Override
public void onPromptStateChanged(MaterialTapTargetPrompt prompt, int state)
{
if (state == MaterialTapTargetPrompt.STATE_FOCAL_PRESSED)
{
// User has pressed the prompt target
}
}
})
.show();
Note
If a target is not set or the target view could not be found or both the primary and secondary text are null then builder.show and builder.create will return null.
Other shapes
The default shape is a circle but any other shape can be rendered by extending the PromptBackground and PromptFocal classes. Custom shapes such as a rectangle can be set by calling setPromptBackground and/or setPromptFocal. Documentation and examples are available here.
