public class ScenesActivity extends Activity implements Animation.AnimationListener, View.OnClickListener {

   final ArrayList<ImageItem> imageItems = new ArrayList<ImageItem>();
   TypedArray imgs = getResources().obtainTypedArray(R.array.image_ids);
   Bitmap farmAnimals = BitmapFactory.decodeResource(this.getResources(), imgs.getResourceId(0, -1));
   imageItems.add(new ImageItem(farmAnimals, "Farm Animals"));

   Bitmap fruitsVeg = BitmapFactory.decodeResource(this.getResources(), imgs.getResourceId(1, -1));
   imageItems.add(new ImageItem(fruitsVeg, "Fruits & Vegetables"));

   Bitmap childrenRoom = BitmapFactory.decodeResource(this.getResources(), imgs.getResourceId(2, -1));
   imageItems.add(new ImageItem(childrenRoom, "Children Room"));

   Bitmap beach = BitmapFactory.decodeResource(this.getResources(), imgs.getResourceId(3, -1));
   imageItems.add(new ImageItem(beach, "Beach"));

   Bitmap transport = BitmapFactory.decodeResource(this.getResources(), imgs.getResourceId(4, -1));
   imageItems.add(new ImageItem(transport, "transport"));

   return imageItems;
}

private void initializeClicks(){
   mBack = (Button) findViewById(R.id.back);
   mExit = (Button) findViewById(R.id.exit);
   mAbout = (Button) findViewById(R.id.about);
   mBack.setOnClickListener(this);
   mExit.setOnClickListener(this);
   mAbout.setOnClickListener(this);
}

单击ScenesActivity该过程后意外停止。我已经调试了代码，当它尝试在initializeClicks()方法中设置点击侦听器时问题就开始了。我不知道如何解决它。有人可以帮助解决这个问题吗？
