## Demo (YouTube)
## Getting Started
1. Make sure that you've added the `mavenCentral()` repository to your top-level `build.gradle` file.
````groovy
buildscript {
//...
repositories {
//...
mavenCentral()
}
//...
}
````
2. Add the library dependency to your module-level `build.gradle` file.
````groovy
dependencies {
implementation "com.paulrybitskyi.persistentsearchview:persistentsearchview:1.1.5"
}
````
3. If your `targetSdk` is **30** and you want to use the voice search feature, add these lines to your app's `AndroidManifest.xml`:
````xml
//...
//...
````
4. Proceed with the implementation of your own search view.
## Basic Implementation
Implementation of a PersistentSearchView with basic functionality involves 2 main steps - declaring a widget inside the XML file of your choice and configuring it in one of the Java/Kotlin classes.
Let's implement a PersistentSearchView with basic functionality by following the steps listed above:
1. Declaring a widget inside the XML file.
XML (click to expand)
````xml
````
2. Configuring the widget in one of the Java/Kotlin classes.
Kotlin (click to expand)
````kotlin
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.demo_activity_layout)
//...
with(persistentSearchView) {
setOnLeftBtnClickListener {
// Handle the left button click
}
setOnClearInputBtnClickListener {
// Handle the clear input button click
}
// Setting a delegate for the voice recognition input
setVoiceRecognitionDelegate(VoiceRecognitionDelegate(this@DemoActivity))
setOnSearchConfirmedListener { searchView, query ->
// Handle a search confirmation. This is the place where you'd
// want to perform a search against your data provider.
}
// Disabling the suggestions since they are unused in
// the simple implementation
setSuggestionsDisabled(true)
}
}
//...
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
// Calling the voice recognition delegate to properly handle voice input results
VoiceRecognitionDelegate.handleResult(persistentSearchView, requestCode, resultCode, data)
}
````
Java (click to expand)
````java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.demo_activity_layout);
//...
persistentSearchView.setOnLeftBtnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
// Handle the left button click
}
});
persistentSearchView.setOnClearInputBtnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
// Handle the clear input button click
}
});
// Setting a delegate for the voice recognition input
persistentSearchView.setVoiceRecognitionDelegate(new VoiceRecognitionDelegate(this));
persistentSearchView.setOnSearchConfirmedListener(new OnSearchConfirmedListener() {
@Override
public void onSearchConfirmed(PersistentSearchView searchView, String query) {
// Handle a search confirmation. This is the place where you'd
// want to perform a search against your data provider.
}
});
// Disabling the suggestions since they are unused in
// the simple implementation
persistentSearchView.setSuggestionsDisabled();
}
//...
@Override
protected fun onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Calling the voice recognition delegate to properly handle voice input results
VoiceRecognitionDelegate.handleResult(persistentSearchView, requestCode, resultCode, data);
}

## Basic Recent Suggestions Implementation
Implementation of a PersistentSearchView with recent suggestions is pretty much the same as [Basic Implementation](#basic-implementation) with one exception: the view configuration.
In this implementation you'll need to provide a bit more configuration for the widget in order to show recent suggestions to the user, such as providing implementation for a couple of listeners as well as fetching suggestions from your data provider and setting them to the search view.
For example, here is the configuration of the widget with recent suggestions functionality:
Java (click to expand)
````java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.demo_activity_layout);
//...
persistentSearchView.setOnLeftBtnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
// Handle the left button click
}
});
persistentSearchView.setOnClearInputBtnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
// Handle the clear input button click
}
});
// Setting a delegate for the voice recognition input
persistentSearchView.setVoiceRecognitionDelegate(new VoiceRecognitionDelegate(this));
persistentSearchView.setOnSearchConfirmedListener(new OnSearchConfirmedListener() {
@Override
public void onSearchConfirmed(PersistentSearchView searchView, String query) {
// Handle a search confirmation. This is the place where you'd
// want to save a new query and perform a search against your
// data provider.
}
});
persistentSearchView.setOnSearchQueryChangeListener(new OnSearchQueryChangeListener() {
@Override
public void onSearchQueryChanged(PersistentSearchView searchView, String oldQuery, String newQuery) {
// Handle a search query change. This is the place where you'd
// want load new suggestions based on the newQuery parameter.
}
});
persistentSearchView.setOnSuggestionChangeListener(new OnSuggestionChangeListener() {
@Override
public void onSuggestionPicked(SuggestionItem suggestion) {
// Handle a suggestion pick event. This is the place where you'd
// want to perform a search against your data provider.
}
@Override
public void onSuggestionRemoved(SuggestionItem suggestion) {
// Handle a suggestion remove event. This is the place where
// you'd want to remove the suggestion from your data provider.
}
});
}
//...
@Override
public void onResume() {
super.onResume();
List searchQueries = null;
// Fetching the search queries from the data provider
if(persistentSearchView.isInputQueryEmpty) {
searchQueries = mDataProvider.getInitialSearchQueries();
} else {
searchQueries = mDataProvider.getSuggestionsForQuery(persistentSearchView.inputQuery);
}
// Converting them to recent suggestions and setting them to the widget
persistentSearchView.setSuggestions(SuggestionCreationUtil.asRecentSearchSuggestions(searchQueries), false);
}
//...
@Override
protected fun onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Calling the voice recognition delegate to properly handle voice input results
VoiceRecognitionDelegate.handleResult(persistentSearchView, requestCode, resultCode, data);
}
````
Kotlin (click to expand)
````kotlin
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.demo_activity_layout)
//...
with(persistentSearchView) {
setOnLeftBtnClickListener {
// Handle the left button click
}
setOnClearInputBtnClickListener {
// Handle the clear input button click
}
// Setting a delegate for the voice recognition input
setVoiceRecognitionDelegate(VoiceRecognitionDelegate(this@DemoActivity))
setOnSearchConfirmedListener { searchView, query ->
// Handle a search confirmation. This is the place where you'd
// want to save a new query and perform a search against your
// data provider.
}
setOnSearchQueryChangeListener { searchView, oldQuery, newQuery ->
// Handle a search query change. This is the place where you'd
// want load new suggestions based on the newQuery parameter.
}
setOnSuggestionChangeListener(object : OnSuggestionChangeListener {
override fun onSuggestionPicked(suggestion: SuggestionItem) {
// Handle a suggestion pick event. This is the place where you'd
// want to perform a search against your data provider.
}
override fun onSuggestionRemoved(suggestion: SuggestionItem) {
// Handle a suggestion remove event. This is the place where
// you'd want to remove the suggestion from your data provider.
}
})
}
}
//...
override fun onResume() {
super.onResume()
// Fetching the search queries from the data provider
val searchQueries = if(persistentSearchView.isInputQueryEmpty) {
mDataProvider.getInitialSearchQueries()
} else {
mDataProvider.getSuggestionsForQuery(persistentSearchView.inputQuery)
}
// Converting them to recent suggestions and setting them to the widget
persistentSearchView.setSuggestions(SuggestionCreationUtil.asRecentSearchSuggestions(searchQueries), false)
}
//...
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
// Calling the voice recognition delegate to properly handle voice input results
VoiceRecognitionDelegate.handleResult(persistentSearchView, requestCode, resultCode, data)
}

## Basic Regular Suggestions Implementation
Implementation of a PersistentSearchView with regular suggestions is identical to the [Basic Recent Suggestions Implementation](#basic-recent-suggestions-implementation) with one exception: suggestions creation method [asRecentSearchSuggestions(searchQueries)](https://github.com/mars885/persistentsearchview/blob/master/persistentsearchview/src/main/java/com/paulrybitskyi/persistentsearchview/utils/SuggestionCreationUtil.java#L47) should be replaced with [asRegularSearchSuggestions(searchQueries)](https://github.com/mars885/persistentsearchview/blob/master/persistentsearchview/src/main/java/com/paulrybitskyi/persistentsearchview/utils/SuggestionCreationUtil.java#L62).
## Advanced Use
See the [Sample app](https://github.com/mars885/persistentsearchview/tree/master/sample).
## Difference between recent and regular suggestions
The difference between recent and regular suggestions is that a user can remove recent suggestions from the list while regular suggestions cannot be removed (there is no remove button on the regular suggestions).
For example, here are screenshots of recent suggestions compared to regular:
Recent
Regular
