Trying to make a flipping card in an android application

Question

I'm trying for 2 weeks now to create a flipping layout in an android app, but nothing.. all the tutorials on the internet I've read, but nothing.. please, could someone, please, help me with this.. this is my Flippingactivity:

package com.ad;
import android.R;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.AnimationUtils;
import android.widget.ImageView;
import android.app.Activity;
public class MainActivity extends Activity implements OnClickListener,
AnimationListener {

       private Animation animation1;
       private Animation animation2;
       private boolean isBackOfCardShowing = true;
       @Override
       protected void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);
             setContentView(R.layout.activity_main);
             animation1 = AnimationUtils.loadAnimation(this, R.anim.to_middle);
             animation1.setAnimationListener(this);
             animation2 = AnimationUtils.loadAnimation(this, R.anim.from_middle);
             animation2.setAnimationListener(this);
             findViewById(R.id.button1).setOnClickListener(this);
       }
       @Override
       public void onClick(View v) {
              v.setEnabled(false);
              ((ImageView)findViewById(R.id.imageView1)).clearAnimation();
              ((ImageView)findViewById(R.id.imageView1)).setAnimation(animation1);
              ((ImageView)findViewById(R.id.imageView1)).startAnimation(animation1);
        }
        @Override
        public void onAnimationEnd(Animation animation) {
              if (animation==animation1) {
                     if (isBackOfCardShowing) {
        ((ImageView)findViewById(R.id.imageView1)).setImageResource(R.drawable.card_front2);
                       } else {
        ((ImageView)findViewById(R.id.imageView1)).setImageResource(R.drawable.card_back);
                       }
                       ((ImageView)findViewById(R.id.imageView1)).clearAnimation();
         ((ImageView)findViewById(R.id.imageView1)).setAnimation(animation2);
         ((ImageView)findViewById(R.id.imageView1)).startAnimation(animation2);
                 } else {
                        isBackOfCardShowing=!isBackOfCardShowing;
                        findViewById(R.id.button1).setEnabled(true);
                 }
        }
        @Override
        public void onAnimationRepeat(Animation animation) {
               // TODO Auto-generated method stub
        }
        @Override
        public void onAnimationStart(Animation animation) {
        // TODO Auto-generated method stub
        }
}

Ok. So the problems: 1. At the setContentView, if I put my activity_main, it says that it can not be resolved or it is no a field.. 2. They are not recognizing my anim folder where I was the transition.. I created the anim folder in /res, but they still not recognising my xmls files.. 3. At R.id.imageView1 they are not recognising my image id too..

I tried: clean the project.. nothing. Refresh the /res before making the xmls.. nothing. Importing .R in many different ways.. nothing.. nothing.. nothing. HELP !

So. I'am backing someone who knows what's happening to help me, I'am exhausted of trying, and trying but nothing. PLEASE, please, please, help me a little bit.Thanks, and I'll be grateful. Have a nice day !!!

If you rename your layout file to something else does it work? Could be that references are not generating. — RED_, Jan 26 '14 at 17:03

You didn't post enough information to fully understand the problem you are having, but i'm guessing that this training article will help you.

What do you want to know more? Tell me and i'll specify exactly what you want to know for helping me. I tried that tutorial too...but its not exactly what I want..This are my issues: 1. At the setContentView, if I put my activity_main, it says that it can not be resolved or it is no a field.. 2. They are not recognizing my anim folder where I was the transition.. I created the anim folder in /res, but they still not recognising my xmls files.. 3. At R.id.imageView1 they are not recognising my image id too.. – user3104504 Jan 26 '14 at 16:58
