Question

我使用这个library成功获得一个垂直图像滑块，工作正常。只有我坚持的部分才能垂直滑动。现在我必须水平滑动以使我的图像滑动，如here所示，但我想垂直滑动所以你知道它是有道理的。提前感谢你能解决这个问题的人，我到处寻找：）

customSwipedapter.java

public class customSwipeAdapter extends PagerAdapter {

private int[] images = {R.drawable.img1, R.drawable.img2, R.drawable.img3};
private Context ctx;
private LayoutInflater layoutInflator;

public customSwipeAdapter(Context ctx) {
    this.ctx = ctx;
}

@Override
public int getCount() {
    return images.length;
}

@Override
public boolean isViewFromObject(View view, Object o) {
    return (view == (RelativeLayout)o);
}

@Override
public Object instantiateItem(ViewGroup container, int position) {
    layoutInflator = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View item_view = layoutInflator.inflate(R.layout.swipe_layout, container, false);
    ImageView imageView = (ImageView) item_view.findViewById(R.id.image_view);
    imageView.setImageResource(images[position]);
    container.addView(item_view);

    return item_view;
}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    container.removeView((RelativeLayout)object);
   }
}

mainActivity.java

public class savedImagesViewController extends AppCompatActivity {

ViewPager viewPager;
customSwipeAdapter adapter;
Bitmap bitmap ;
Thread thread ;
String evalue;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_saved_cards_view_controller);

    EditText e1 = (EditText) findViewById(R.id.editText);

    viewPager = (ViewPager) findViewById(R.id.view_pager);
    adapter = new customSwipeAdapter(this);
    viewPager.setAdapter(adapter);
    viewPager.setPageTransformer(false, new DefaultTransformer());
   }
}
