EasyAutoComplete

How to To get a Git project into your build:

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Step 2. Add the dependency

dependencies {
        implementation 'com.github.Harmanbeer007:EasyAutoComplete:0.0.7'
}

Step 3.Add AutoCompleteView in XML

<harmanbeer007.easylibrary.easyautocompleteview.EasyAutoCompleteView
    android:id="@+id/auto_text"
    android:layout_width="fill_parent"
    android:layout_height="40dp"
    android:layout_marginLeft="8dp"
    android:layout_marginTop="8dp"
    android:layout_marginRight="8dp"
    android:background="@android:color/white"
    android:hint="wiki text"
    android:paddingLeft="10dp"
    android:singleLine="true"
    android:textColor="@android:color/black"
    android:textSize="18sp"
    app:autocompleteParam="search"
    app:autocompleteUrl="https://en.wikipedia.org/w/api.php?action=opensearch&amp;format=json&amp;"
    app:modelClass="harmanbeer007.easylibrary.model.WikiItem"
    app:rowLayout="@layout/row_wiki" />

here you have to declare four parameter

app:autocompleteParam="search" 
//attribute required by api end point i.e q=red,query=red,search=red etc.

app:autocompleteUrl="https://en.wikipedia.org/w/api.php?action=opensearch&format=json&" 
//API end point without search paramter here ,as we already defined it in app:autocompleteParam 

app:modelClass="harmanbeer007.easylibrary.model.WikiItem"
//model class for response need that needs to be parsed.

app:rowLayout="@layout/row_wiki" 
//layout to be showen

<-------------------------------------------IN JAVA FILE------------------------------------------------------>

//find the autocompleteview

mWikiAutoComplete = (EasyAutoCompleteView) findViewById(R.id.auto_text);
    
//setup the parser for the response you will get after API hit.

mWikiAutoComplete.setParser(new EasyAutoCompleteView.AutoCompleteResponseParser() {

        @Override
        public ArrayList<? extends Object> parseAutoCompleteResponse(
                String response) {
            Log.d("MainActivity", "Response: " + response);
            ArrayList<WikiItem> models = new ArrayList<WikiItem>();
            try {
                JSONArray jsonArray = new JSONArray(response);
                JSONArray array = jsonArray.optJSONArray(1);
                if (array != null) {
                    for (int i = 0; i < array.length(); i++) {
                        models.add(new WikiItem(array.getString(i)));
                    }
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }

            return models;
	//here you return the model with attributes that you need to use when selectin is done by user from auto suggestions.
        }
    });
    ((EasyAutoCompleteView) findViewById(R.id.auto_text)).setSelectionListener(
	new EasyAutoCompleteView.AutoCompleteItemSelectionListener() {
    		@Override
        		public void onItemSelection(Object obj) {
    		//find the object here that you sent from parser.
            	WikiItem wikiItem = (WikiItem) obj;
            	((EasyAutoCompleteView) findViewById(R.id.auto_text)).setText(wikiItem.getItem());
            	((EasyAutoCompleteView) findViewById(R.id.auto_text)).clearFocus();
        }
    });

Note

if you are using a non secure domain and targetting android Pie you might not get any results,so please use these options

Option 1 -

Create file res/xml/network_security_config.xml -replace abc.com here with your domain without leading http://

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
	<domain includeSubdomains="true">abc.com</domain>
    </domain-config>
</network-security-config>

AndroidManifest.xml -

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
	...
	android:networkSecurityConfig="@xml/network_security_config"
	...>
	...
    </application>
</manifest>

Option 2 -

AndroidManifest.xml -

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
	...
	android:usesCleartextTraffic="true"
