Question

之前已经问过这个问题，但是如果这是一个重复的问题，我找不到答案。但我的gridView只是重复传递给它的最后一张图片。

这是我的onActivityResult，我从手机图库中选择最多六张图片

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode == RESULT_OK)
    {
        if(requestCode == PICK_IMAGE_MULTIPLE)
        {
            ArrayList<Bitmap> items = new ArrayList<Bitmap>();
            String[] imagesPath = data.getStringExtra("data").split("\\|");

            try
            {
                lnrImages.removeAllViews();
            }
            catch (Throwable e)
            {
                e.printStackTrace();
            }

            for (int i=0; i<imagesPath.length; i++)
            {
                yourbitmap = BitmapFactory.decodeFile(imagesPath[i]);
                items.add(yourbitmap);
            }

            adapter = new ImageAdapter(this, R.id.grdImages, items);
            gridView.setAdapter(adapter);
        }
    }
}

这是我的imageadapter

public class ImageAdapter extends ArrayAdapter<Bitmap>
{
Bitmap bm;
private Context context;
private ArrayList<Bitmap> items;

public ImageAdapter(Context context, int textViewResourceId, ArrayList<Bitmap> items) {
    super(context, textViewResourceId, items);
    this.context = context;
    this.items = items;
}

@Override
public View getView(int position, View convertView, ViewGroup parent)
{

    ImageView imageView;

    if (convertView == null)
    {
        imageView = new ImageView(context);
        imageView.setLayoutParams(new GridView.LayoutParams(185, 185));
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setPadding(5, 5, 5, 5);
    }
    else
    {
        imageView = (ImageView) convertView;
    }

    for (int i = 0; i < items.size(); i++)
    {
        bm = items.get(i);
        imageView.setImageBitmap(bm);
        return imageView;
    }

    return imageView;

}
}

感谢任何反馈，作为培训的程序员，非常感谢。

删除此块...

for (int i = 0; i < items.size(); i++) { 
     bm = items.get(i);
     imageView.setImageBitmap(bm); 
     return imageView;
     }

并添加此

imageView.setImageBitmap(items.get(position));

当您调用getView方法时，您不能使用for循环〜＆＃39;

记住ListView和GridView需要一个数据源，无论你想在listView / gridView上更改内容，都要更改数据源。

你可以在getView方法中执行此操作

.work {
  max-height: auto;
  background-color: #f2f2f2;
  font-family: Myriad Pro;
  text-align: center;
}

.work .container {
  width: 100%;
  height: 90%;
  padding: 5% 5%;
}

.work img {
  width: 100%;
  height: 100%;
  border: 2px solid GhostWhite;
  border-radius: 4px;
  margin-top: 10px;
  overflow: hidden;
}

.work button {
  margin-top: 10px;
  float: left;
  background-color: #0080ff;
  border-radius: 4px;
  border: 2px solid GhostWhite;
  margin-bottom: 30px;
  padding: 10px 20px;
  text-align: center;
}

.work button a {
  color: #ffffff;
  font-weight: lighter;
  text-decoration: none;
}


/* About me */

.about {
  background-color: #000000;
  #ffffff;
  max-height: auto;
  max-width: 100%;
  font-family: Myriad Pro;
  text-align: center;
}

.about .container {
  max-width: 100%;
  max-height: 100%;
  padding: 10%;
  font-size: 1.2rem;
}

public View getView（int position，View convertView，ViewGroup parent） {

<div class="work">
  <div class="container">
    <h3>MY WORK</h3>
