Java Android drawable刷卡不工作（来自初学者示例代码）

我精通java已有几年了，但从未尝试过制作应用程序。所以两天前我就开始了，从让android studio在netbeans中设置它到在我的手机上显示hello world应用程序只需要20分钟。但现在我仍然坚持使用这种方法来浏览一系列jpg。该应用程序得到构建并启动，但不显示我的任何图片。请看一看

    package vf.base;

import android.app.Activity;
import android.content.res.TypedArray;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.ViewFlipper;

public class MainActivity extends Activity {

    private ViewFlipper viewFlipper;
    private TypedArray pics;
    private OnSwipeTouchListener onSwipeTouchListener;

    /**
     * Called when the activity is first created.
     */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        pics = getResources().obtainTypedArray(R.array.pics);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        viewFlipper = (ViewFlipper) findViewById(R.id.viewFlipper);
        for (int i = 0; i < pics.length(); i++) {
            AddViewFlipper(i);
        }

        onSwipeTouchListener = new OnSwipeTouchListener(this) {
            @Override
            public void onSwipeRight() {
                viewFlipper.showNext();
            }

            @Override
            public void onSwipeLeft() {
                viewFlipper.showPrevious();
            }
        };

        viewFlipper.setOnTouchListener(onSwipeTouchListener);
    }

    private void AddViewFlipper(int position) {
        ImageView imageView = new ImageView(MainActivity.this);
        imageView.setImageResource(position);
        ViewGroup.LayoutParams imageParams = new ViewGroup.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT,            ViewGroup.LayoutParams.MATCH_PARENT);
        imageView.setLayoutParams(imageParams);

        viewFlipper.addView(imageView);
    }

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        onSwipeTouchListener.gestureDetector.onTouchEvent(ev);
        return super.dispatchTouchEvent(ev);
    }
}
