I custom the BaseAdapter to show image array with full-screen mode. I
want the user can flick the images so I use the gallery class.When a
image displays on the screen, a correlative sentence should be showed
as well.
The issue is the position param in getView function jump abnormally,
especially when I flick into more one picture at a time. Therefore the
string is showed incorrectly, I don't know why the image still
displays normally.
Here is my code:
public class ImageAdapter extends BaseAdapter {
int mGalleryItemBackground;
private Context mContext;
private Integer[] mImageIds = {
R.drawable.number1,
R.drawable.number2,
R.drawable.number3,
R.drawable.number4,
R.drawable.number5,
R.drawable.number6,
R.drawable.number7,
R.drawable.number8,
R.drawable.number9,
R.drawable.number10
};
private String[] captions = {
"1. How ",
"2. How ",
"3. How ",
"4. How ",
"5. How ",
"6. How ",
"7. What ",
"8. How ",
"9. How ",
"10. What "
};
public ImageAdapter(Context c) {
mContext = c;
TypedArray a = c.obtainStyledAttributes(Gallery1);
mGalleryItemBackground = a.getResourceId(
Gallery1_android_galleryItemBackground, 0);
a.recycle();
}
public int getCount() {
return mImageIds.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup
parent) {
ImageView i = new ImageView(mContext);
Log.i("position"," == "+ position);
i.setImageResource(mImageIds[position]);
textview.setText(captions[position]);
i.setLayoutParams(new Gallery.LayoutParams
(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
i.setScaleType(ImageView.ScaleType.FIT_CENTER);
i.setBackgroundResource(mGalleryItemBackground);
return i;
}
}
=================
Please let me know if you have any idea.
Thanks in advance.
