我正在尝试显示 6 张图像，这些图像已保存在 gridview 的 res/drawable 文件夹中。

但我收到以下错误

这是我的适配器类

public class ImageAdapter extends BaseAdapter {
    Context mcontext;
    Integer Imageid[] = new Integer[] { R.drawable.image1, R.drawable.image3,
            R.drawable.image4, R.drawable.image5, R.drawable.image6,
            R.drawable.image2 };



    public ImageAdapter(Context context) {
        // TODO Auto-generated constructor stub
        super();
        this.mcontext = context;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return Imageid.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        LayoutInflater inflater = (LayoutInflater) mcontext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View gridView;
        if(convertView == null){
            gridView = new View(mcontext);

            gridView = inflater.inflate(R.layout.imageview,null);

            ImageView imageView =(ImageView)gridView.findViewById(R.id.imageView);
            imageView.setImageResource(Imageid[position]);
        }
            else {
                gridView = (View) convertView;
            }


        return gridView;
    }

}

为什么会出现这个错误？...

提前致谢：）

这里发生的是，，，应用程序超出堆大小。因此，您必须以某种方式解码图像，使其低于堆大小。在您的适配器中执行此代码

 @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        LayoutInflater inflater = (LayoutInflater) mcontext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View gridView;
        if(convertView == null){
            gridView = new View(mcontext);

            gridView = inflater.inflate(R.layout.imageview,null);
            ImageView imageView =(ImageView)gridView.findViewById(R.id.imageView);

            BitmapFactory.Options options = new BitmapFactory.Options();
            options.inDither = false;
            options.inJustDecodeBounds = false;
            options.inPreferredConfig = Bitmap.Config.ARGB_8888;
            options.inSampleSize = 3;
            options.inPurgeable = true;

            Bitmap icon = BitmapFactory.decodeResource(context.getResources(),
                    Imageid[position],options);


            holder.imageView.setImageBitmap(icon);
        }
            else {
                gridView = (View) convertView;
            }


        return gridView;
    }

您使用的图像很大。
看看这篇文章
或
缩小你的图像。- 减少它们的尺寸和质量。

尝试根据各个网格大小减小图像的大小。检查链接。 如何在 Android 中调整图像大小？
