    我要如何刷卡全屏选择的网格图像我要、网格、全屏、图像

    2023-09-07 22:11:53 作者：北溟有鱼

    我创建了一个网格视图图像应用程序，我想显示图像刷卡所选的图像。

    其实我实现了图像轻扫在我的应用程序的，但的问题是图像刷卡开始从第一图像不是从选定的图像。

    例如：

    如果我选择第3图像图像轻扫应该开始从第3图像不会从第一形象。

    我的code：

      ImageView的ImageView的=新ImageView的（上下文）;
// INT填充= context.getResources（）。getDimensionPixelSize（
// R.dimen.padding_large）;
// imageView.setPadding（填充，填充，填充，填充）;
      imageView.setScaleType（ImageView.ScaleType.CENTER_INSIDE）;
      imageView.setImageResource（图标[位置]）;
      （（ViewPager）容器）.addView（ImageView的，0）;
      返回ImageView的;
    }

    @覆盖
    公共无效destroyItem（ViewGroup中的容器，INT位置，Object对象）
    {
      （（ViewPager）容器）.removeView（（ImageView的）对象）;
    }
  }
}

    解决方案

    后过多的废话/错误，我终于得到了答案，这是非常简单的...;） 

      //获取意图数据
    意图I = getIntent（）;

    //选择的图片ID
    。INT位置= i.getExtras（）调用getInt（ID）;

ViewPager viewPager =（ViewPager）findViewById（R.id.view_pager）;
    ImagePagerAdapter适配器=新ImagePagerAdapter（）;
    viewPager.setAdapter（适配器）;
    viewPager.setCurrentItem（位置）;

    这是简单的答案，而不是这个code： 

      ImagePagerAdapter适配器=新ImagePagerAdapter（mContext，图标[位置]）;

    这个工作。 

      viewPager.setCurrentItem（位置）;

    现在下面是我的洞的应用程序code：

    i created a grid-view image app, and i want to show selected image in image swipe.

    actually i implemented image swipe in my app but the problem is image swipe starts from 1st image not from selected image.

    example:

    if i choose 3rd image image swipe should starts from 3rd image not from 1st image.

    my code:

    解决方案

    after too much bullshit / errors i finally got the answer and it's very simply...;)

    // get intent data
    Intent i = getIntent();

    // Selected image id
    int position = i.getExtras().getInt("id");

ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
    ImagePagerAdapter adapter = new ImagePagerAdapter();
    viewPager.setAdapter(adapter);
    viewPager.setCurrentItem(position);

    this is the simple answer instead of this code:

    ImagePagerAdapter adapter = new ImagePagerAdapter(mContext , icons[position]);

    this worked.

    viewPager.setCurrentItem(position);

    now below is my hole app code:
