It's my first app so i am not use to code on java.
I have a gridview wich display thumbnails from the sdcard, but i can't have
a smooth scroll.
If I put the /* Treatment part*/ out of the if the scroll is like i want
but they are duplicate content and a part of the pics are not displayed.
Here is my code:
-Activity:
<code>
GridView gridview = (GridView) findViewById(R.id.gridview1);
String[] projection = {MediaStore.Images.Media._ID};
String path ="/mnt/sdcard/Pictures";
// Create the cursor pointing to the SDCard
cursor = managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection,
//MediaStore.Images.Media.DATA + " like ? ",
//new String[] {"%Pictures%Sopi%"},
"_data LIKE '%" + path + "/%'",
null,
MediaStore.Images.Media._ID);
// Get the column index of the Media Image ID
columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID);
gridview.setAdapter(new ImageAdapterTest(RoomRawActivity.this));
</code>
-imageAdapater (get view):
<code>
public View getView(int position, View convertView, ViewGroup parent) {
Log.v("adapter - getView","getView start!!");
//Toast.makeText(mContext, "getView start!!"+position, 0).show();
//Move cursor to current position
RoomRawActivity.cursor.moveToPosition(position);
ImageView picturesView;
if (convertView == null) {
picturesView = new ImageView(mContext);
/* treatment */
// Get the current value for the requested column
int imageID = RoomRawActivity.cursor.getInt(RoomRawActivity.columnIndex);
// obtain the image URI
Uri uri = Uri.withAppendedPath( MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
Integer.toString(imageID) );
String url = uri.toString();
//Set the content of the image based on the image URI
int originalImageId = Integer.parseInt(url.substring(url.lastIndexOf("/") + 1,
url.length()));
Bitmap b =
MediaStore.Images.Thumbnails.getThumbnail(mContext.getContentResolver(),
originalImageId,
MediaStore.Images.Thumbnails.MINI_KIND,
null);
picturesView.setPadding(5, 5, 5, 5);
picturesView.setBackgroundResource(R.drawable.border_grid_pics);
picturesView.setImageBitmap(b);
picturesView.setScaleType(ImageView.ScaleType.FIT_XY);
/* END treatment */
}
}else{
picturesView = (ImageView) convertView;
}
return picturesView;
}
</code>
Many thanks!
David.
