によるカスタム水平を使用してこの問題を解決しました
HorizontalImageAdapter.java
を使用するように彼のクラスを変更しましたCursorAdapter
。
ここでの私の解決策:
public class HorizontalImageAdapter extends CursorAdapter {
//...some initialization here
public HorizontalImageAdapter(Context context, Cursor c, int count) {
super(context, c, true);
this.context = (Activity) context;
this.count = count;
this.cursor = c;
inflater = LayoutInflater.from(context);
cursor.moveToFirst();
}
private static class ViewHolder {
public ImageView imageview;
public TextView textview;
public ImageView imageviewvideo;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
cursor.moveToPosition(position);
if (convertView == null) {
Log.d(TAG, "converView == null <<<<<<<<<<<<<<<<<<<<<<<<");
convertView = inflater.inflate(R.layout.activity_media_items, null);
holder = new ViewHolder();
holder.textview = (TextView) convertView.findViewById(R.id.tv_details_title);
holder.imageview = (ImageView) convertView.findViewById(R.id.iv_details_resource_image);
holder.imageviewvideo = (ImageView) convertView.findViewById(R.id.iv_details_resource_video);
convertView.setTag(holder);
} else {
Log.d(TAG, "converView != null >>>>>>>>>>>>>>>>>>>>>>>>");
}
//get the type of the item
type = cursor.getString(cursor.getColumnIndex(DatabaseHelper.FIELD_ITEM_TYPE));
if(type.equalsIgnoreCase("text")){
//handle for text item
}
if(type.equalsIgnoreCase("image")){
//handle for image item
}
if(type.equalsIgnoreCase("video")){
//handle for video item
}
return convertView;
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
ViewHolder holder = (ViewHolder) view.getTag();
String title = cursor.getString(cursor.getColumnIndex(DatabaseHelper.FIELD_TITLE));
String fileName = cursor.getString(cursor.getColumnIndex(DatabaseHelper.FIELD_RESOURCE));
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
ViewHolder holder = new ViewHolder();
View eachitem = inflater.inflate(R.layout.activity_media_items, parent, false);
holder.textview = (TextView) eachgrid.findViewById(R.id.tv_details_title);
holder.imageview = (ImageView) eachgrid.findViewById(R.id.iv_details_resource_image);
holder.imageviewvideo = (ImageView) eachgrid.findViewById(R.id.iv_details_resource_video);
eachgrid.setTag(holder);
return eachitem;
}
}
そしてXML:
