How can I disable/enable GPS programmatically in android?

This example demonstrates how do I disable/enable GPS programmatically in android.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
   xmlns:android="https://schemas.android.com/apk/res/android"
   xmlns:tools="https://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".MainActivity">
   <Button
      android:id="@+id/buttonGps"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerInParent="true"
      android:text="Enable/Disable GPS"/>
   <TextView
      android:id="@+id/textView"
      android:layout_centerInParent="true"
      android:layout_marginBottom="20dp"
      android:layout_above="@id/buttonGps"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:textSize="24sp"
      android:text="Location Services" />
</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.java

import android.content.Context;
import android.content.Intent;
import android.location.LocationManager;
import android.provider.Settings;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
   TextView textView;
   Button buttonGps;
   Context context;
   LocationManager locationManager ;
   boolean GpsStatus ;
   @Override
   public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      textView = findViewById(R.id.textView);
      buttonGps = findViewById(R.id.buttonGps);
      context = getApplicationContext();
      CheckGPSStatus();
      buttonGps.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
         Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
         startActivity(intent);
      }
   });
}
  private void CheckGPSStatus() {
   locationManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
   GpsStatus = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
      if(GpsStatus) {
         textView.setText("Location Services Is Enabled");
      } else {
         textView.setText("Location Services Is Disabled");
      }
   }
}

Step 4 − Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="https://schemas.android.com/apk/res/android"
   package="app.com.sample">
   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
   <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">
      <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>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –
