영어로 미리 죄송합니다.ImageView의 Android 이미지 폴더
내 스마트 폰의 이미지 폴더를 가져오고 싶습니다. 갤러리를 만들기 위해이 이미지들을 사용하고 싶습니다. 배열의 각 이미지를 ImageView에 넣을 수 없으면 배열에 이미지를 넣을 때 문제가 발생합니다.
그것은
public class SeeGallery extends Activity {
File[] listFile ;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_see_gallery);
File folder = new File(Environment.getExternalStorageDirectory() + "/ProjectKozaImages");
listFile = folder.listFiles();
// Note that Gallery view is deprecated in Android 4.1---
Gallery gallery = (Gallery) findViewById(R.id.gallery1);
gallery.setAdapter(new ImageAdapter(this));
gallery.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position,long id)
{
// display the images selected
ImageView imageView = (ImageView) findViewById(R.id.image1);
imageView.setImageResource(listFile[position]);
}
});
}
public class ImageAdapter extends BaseAdapter {
private Context context;
private int itemBackground;
public ImageAdapter(Context c)
{
context = c;
// sets a grey background; wraps around the images
TypedArray a =obtainStyledAttributes(R.styleable.MyGallery);
itemBackground = a.getResourceId(R.styleable.MyGallery_android_galleryItemBackground, 0);
a.recycle();
}
// returns the number of images
public int getCount() {
return listFile.length;
}
// returns the ID of an item
public Object getItem(int position) {
return position;
}
// returns the ID of an item
public long getItemId(int position) {
return position;
}
// returns an ImageView view
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(context);
imageView.setImageResource(listFile[position]);
imageView.setLayoutParams(new Gallery.LayoutParams(100, 100));
imageView.setBackgroundResource(itemBackground);
return imageView;
}
}
