用字符串數組設置圖庫[圖像名稱]

Question

我所有的圖像都存儲在可繪製的文件夾中。我希望看到一些圖像的圖庫視圖。

我想要的圖像的名稱是在一個字符串數組中。

我可以通過圖庫視圖來顯示這些圖像嗎？

我發現代碼在下面，這裏的圖像是一個整數。

我可以使用字符串數組嗎？

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; 
    } 
}

如果您的圖片在您的資源中，這很容易。

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; 
    } 
}
