Google Places API Example with AutocompleteTextView(Kotlin/Java)

Here is the simple example of Google Places SDK for Android returns place predictions in response to user search queries.As the user types, the autocomplete service returns suggestions for places such as businesses, addresses, latitude, longitude etc.

Get the full code from Github

 

 

You can add autocompleteTextView  to your app in the following ways:

1) Autocomplete widget to save development time and ensure a consistent user experience.

2) Get places predictions programmatically to create a customised  UI.

Here we will go with Autocomplete widget

Obtaining Google API Key

In order to make requests to Google Places API you need to provide your API key. You can get your API key by going to Google Places APIs console. The same key can be used for all other google services.

 

1)After obtaining the api key add the API key in the manifest file under application tag like:

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="c1c.googleplaceapiexample">

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

    <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="ADD YOUR APIKEY"/>

    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

 

2)Getting the Places list 

Here I am putting both files .kt(for Kotlin) and .java(for Java)

MainActivity.kt

package c1c.googleplaceapiexample

import android.os.Bundle
import android.support.v7.app.AppCompatActivity
import android.widget.Toast
import com.google.android.gms.common.api.Status
import com.google.android.gms.location.places.Place
import com.google.android.gms.location.places.ui.PlaceAutocompleteFragment
import com.google.android.gms.location.places.ui.PlaceSelectionListener

class MainActivity : AppCompatActivity(),PlaceSelectionListener{

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val autocompleteFragment = fragmentManager.findFragmentById(R.id.autocomplete_fragment)
                as PlaceAutocompleteFragment
        autocompleteFragment.setOnPlaceSelectedListener(this)

    }

    override fun onPlaceSelected(p0: Place?) {

          Toast.makeText(applicationContext,""+p0!!.name+p0!!.latLng,Toast.LENGTH_LONG).show();
    }

    override fun onError(status: Status) {
        Toast.makeText(applicationContext,""+status.toString(),Toast.LENGTH_LONG).show();
    }

}

For Java Developers:

MainActivity.java

package c1c.googleplaceapiexample;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.Toast;

import com.google.android.gms.common.api.Status;
import com.google.android.gms.location.places.Place;
import com.google.android.gms.location.places.ui.PlaceAutocompleteFragment;
import com.google.android.gms.location.places.ui.PlaceSelectionListener;

class MainActivity extends AppCompatActivity implements PlaceSelectionListener {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment)
                getFragmentManager().findFragmentById(R.id.autocomplete_fragment);

        autocompleteFragment.setOnPlaceSelectedListener(this);

    }

    public void onPlaceSelected(Place place) {

        Toast.makeText(getApplicationContext(), "" + place.getName() + place.getLatLng(), Toast.LENGTH_LONG).show();
    }

    public void onError(Status status) {
        Toast.makeText(getApplicationContext(), "" + status.toString(), Toast.LENGTH_LONG).show();
    }

}

 

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <android.support.v7.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="16dp"
        android:layout_marginBottom="16dp"
        >

        <fragment
            android:id="@+id/autocomplete_fragment"
            android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            />

    </android.support.v7.widget.CardView>


</android.support.constraint.ConstraintLayout>

 

3) Run the above code
