Vibration on button click in Android Studio

Adding a vibration effect on button click in Android Studio is a great way to provide tactile feedback to the user. Here's how you can do it:

Add vibration permission

1. AndroidManifest.xml In your app's AndroidManifest.xml file, add the following line inside the <manifest> tag:

<uses-permission android:name="android.permission.VIBRATE" />

Here's the complete AndroidManifest.xml file:

AndroidManifest
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.johnpuwein">
    <uses-permission android:name="android.permission.VIBRATE" />  
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
    </application>

</manifest>

2. activity_main.xml In your app's layout XML file, add a Button element with an id:

Here's the complete activity_main.xml file:

activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:id="@+id/button_click"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Click me" />
</RelativeLayout>

3. MainActivity.java In your app's Java file, add the following code to implement the onClick listener for the button:

MainActivity.java
import android.content.Context;
import android.os.Build;
import android.os.Bundle;
import android.os.VibrationEffect;
import android.os.Vibrator;
import android.view.View;
import android.widget.Button;
//John Puwein
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {
    private Button buttonClick;
    private Vibrator vibrator;

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

        // Initialize button and vibrator
        buttonClick = findViewById(R.id.button_click);
        vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);

        // Set onClick listener for button
        buttonClick.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Vibrate the device
                if (Build.VERSION.SDK_INT >= 26) {
                    vibrator.vibrate(VibrationEffect.createOneShot(500, VibrationEffect.DEFAULT_AMPLITUDE));
                } else {
                    vibrator.vibrate(500);
                }
            }
        });
    }
}

In this code, we first initialize the button and the vibrator. Then, we set the onClick listener for the button. When the button is clicked, the vibrator vibrates for 500 milliseconds.

That's it! With these simple steps, you can add a vibration effect on button click in your Android app using Android Studio.

Good luck!
