Question

我的所有图片都存储在drawable文件夹中。我希望看到包含一些图像的图库视图。

我想要的图像名称是字符串数组。

我可以获取图库视图来显示这些图像。

我发现代码如下，这里的图像是整数。

我可以使用String数组吗？

public class ImageAdapter extends BaseAdapter {

    private Context context;

    public ImageAdapter(Context context){
        this.context = context;
    }

    public int getCount() {
        return pics.length;
    }

    public Object getItem(int arg0) {
        return null;
    }

    public long getItemId(int position) {
        return 0;
    }

    public View getView(int arg0, View arg1, ViewGroup arg2) {
        ImageView iv = new ImageView(context);
        iv.setImageResource(pics);
        iv.setScaleType(ImageView.ScaleType.FIT_XY);
        iv.setLayoutParams(new Gallery.LayoutParams(150,120));
        iv.setBackgroundResource(imageBackground);
        return iv;
    }
}

如果您的图片在您的资源中，这很容易。

public class ImageAdapter extends BaseAdapter {

    private Context context;
    private Resources resources;

    private String[] imageNames;

    public ImageAdapter(Context context, String[] imageNames){
        this.context = context;
        this.resources = context.getResources();
        this.imageNames = imageNames;
    }

    public int getCount(){
        return imageNames.length;
    }

    public String getItem(int position){
        return imageNames[position];
    }

    public long getItemId(int position){
        return position;
    }

    public View getView(ViewGroup parent, View convertView, int position){
        if(convertView == null){
            convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.imageview, parent, false);
        }
        int imageId = resources.getIdentifier(getItem(position), "drawable", context.getPackageName());
        ImageView imageView = (ImageView) convertView.findViewById(R.id.imageview);
        imageView.setImageResource(imageId);
        return convertView;
    }
}

使用String数组设置图库[图像名称]
