Display list of images from sd card

I am trying t开发者_运维问答o display a list of images on the SD card to the user, allow them to select multiple images and then store those selected images in an array. Can you provide me any help with this?

public class selectimages extends Activity {

//---the images to display--- Integer[] imageIDs = { R.drawable.a_1, R.drawable.a_2, R.drawable.a_3, R.drawable.a_4, R.drawable.a_5, R.drawable.a_6, R.drawable.a_7

};

@Override    
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.selectimages);

    ListView listview = (ListView) findViewById(R.id.listview);
    listview.setAdapter(new ImageAdapter(this));

    listview.setOnItemClickListener(new OnItemClickListener() 
    {
        public void onItemClick(AdapterView parent, 
        View v, int position, long id) 
        {                
            Toast.makeText(getBaseContext(), 
                    "pic" + (position + 1) + " selected", 
                    Toast.LENGTH_SHORT).show();
        }
    });        
}

public class ImageAdapter extends BaseAdapter 
{
    private Context context;

    public ImageAdapter(Context c) 
    {
        context = c;
    }

    //---returns the number of images---
    public int getCount() {
        return imageIDs.length;
    }

    //---returns the ID of an item--- 
    public Object getItem(int position) {
        return position;
    }

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

    //---returns an ImageView view---
    public View getView(int position, View convertView, ViewGroup parent) 
    {
        ImageView imageView;
        if (convertView == null) {
            imageView = new ImageView(context);
            imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(5, 5, 5, 5);
        } else {
            imageView = (ImageView) convertView;
        }
        imageView.setImageResource(imageIDs[position]);
        return imageView;
    }
}    

}

Behold, getting the checked values of a Listview: previous question.

  /* do whatever you want with the checked item */
 }

You could load those images to the listview with custom listview layout, afterwards put beside each images a checkbox...whenever user tick a checkbox which means he selected the image on that row of listview. Is that what you want?
