How to enable haptic feedback on button view

Solution 1:

UPDATE ON DECEMBER 24TH 2019:

The view must be enabled Haptic function by:

1. Add android:hapticFeedbackEnabled="true" in xml.

2. Or use view.setHapticFeedbackEnabled(true); in code

   (Cited from Ivan Chau)

However, one more thing to take into consideration is to enable Haptic Setting in virtual devices. This is annoying sometimes, so we have some flags come to help (which will ignore these enable Setting somehow):

view.performHapticFeedback(
    HapticFeedbackConstants.VIRTUAL_KEY, 
    HapticFeedbackConstants.FLAG_IGNORE_GLOBAL_SETTING  // Ignore device's setting. Otherwise, you can use FLAG_IGNORE_VIEW_SETTING to ignore view's setting.
);

An example to Mayra is, for run the Haptic Feedback is by using this code.

View view = findViewById(...)
view.performHapticFeedback(HapticFeedbackConstants.VIRTUAL_KEY);

And this line of code can easy be include in you onclick action. The good part with this is you do not need to set a permission in the AndroidManifest (I do not need this on SdkVersion "7" (2.1 or 2.3 is 7 ))

Also note, in my code here, this will only be running if the user has enabled Haptic Feedback as global. See http://developer.android.com/reference/android/view/HapticFeedbackConstants.html for alway use it.

Solution 2:

Here is an answer, though it might not be the best implementation:

import android.view.View;
import android.os.Vibrator;

public class Main extends Activity implements OnClickListener
{
    private View myView;
    private Vibrator myVib;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        myVib = (Vibrator) this.getSystemService(VIBRATOR_SERVICE);

        //myView can be any type of view, button, etc.
        myView = (View) this.findViewById(R.id.myView);
        myView.setOnClickListener(this);
    }

    @Override
    public void onClick(View v)
    {
        myVib.vibrate(50);
        //add whatever you want after this
    }
}

Don't forget, you also need to add the "android.permission.VIBRATE" permission to the program's manifest. You can do so by adding the following to the "AndroidManifest.xml" file:

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

I hope that helps.

Solution 3:

View has a performHapticFeedback function, which should allow you to perform it whenever you want, i.e., on an OnClick listener.
