Good morning classmates!

In the middle of the project that I am developing on Android, I want that when you click on an image, when you push it out, a dialog box appears asking for confirmation:

This is the code I have to open the image:

imgaccesorios.setOnTouchListener(new View.OnTouchListener(){

        public boolean onTouch(View v, MotionEvent event) {
            switch(event.getAction())
            {
                case MotionEvent.ACTION_DOWN :
                    imgaccesorios.setImageResource(R.drawable.accesorios2);
                    vibrator.vibrate(30);
                    break;
                case MotionEvent.ACTION_UP :

                    notificaciones();
                    break;
            }

            return true;
        }

    });

This is the notifications method:

public void notificaciones(){

AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());

builder.setTitle("Your Title");

builder.setMessage("Some message...")
        .setCancelable(false)
        .setPositiveButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // TODO: handle the OK
            }
        })
        .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                dialog.cancel();
            }
        });

AlertDialog alertDialog = builder.create();
alertDialog.show();


}

And this is the error that I get when I press the button:

If you get the error even when the theme of your activity is Theme.AppCompat (or inherit from it directly or indirectly), the reason could be the following.

The first parameter that the Builder receives (to build the Dialog) must be this instead of getApplicationContext() . This applies to the Activity.

I would normally have written this , but I had copied the line from inside an anonymous class.

This error is supposed to be caused because your Activity is trying to apply the ActionBarActivity dialog topic that requires the AppCompat.theme .

Check if in your file styles.xml , your main theme has a parent that is not equal to the following or does not extend the next, that is, that has the same beginning:

<?xml version="1.0" encoding="utf-8"?>
 <resources>
    <style name="AppTheme" parent="@style/Theme.AppCompat"/>
 </resources>

If not, open your Manifest.xml and on the label <activity...> of the one that gives you the error, check the android:theme .

Another possible reason for the failure may be that, in your class, you do not extend AppCompatActivity or if it is a fragment of Fragment .

I hope I helped you, check it out and tell me if it worked.

Good luck in your app !!
