[android-developers] Gallery View and SQLite database
Hi all, I have a sqlite database of 100+ low res images saved as Blob data. I am creating an App that has a GalleryView and I would like to display the 100+ images from my database in this view. The user can scroll through the horizontally scrolling list and select the one he wants to see full screen. I am using a sample app that takes sample images from 'res/drawable' folder to display them on the gallery view. I would like to do the same but pull images from the database instead. Can someone guide me? Thanks, AB -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Gallery view problems - external memory
Hi all,
I have developed a very simple gallery (it started as the hello
gallery example) where I have added code to get the images from the
content provider. It should return all images from the SD card but it
is returning no images, my gallery view is blank. I am a fairly new
developer, just working my way around the tutorials online. Here is
the code.
package com.tutorials;
import java.util.ArrayList;
import android.app.Activity;
import android.content.ContentResolver;
import android.content.Context;

public class HelloGallery extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Gallery g = (Gallery)findViewById(R.id.gallery);
g.setAdapter(new ImageAdapter(this));
g.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView parent, View v, int
position, long id){
Toast.makeText(HelloGallery.this, + position,
Toast.LENGTH_SHORT).show();
}
});
}
public class ImageAdapter extends BaseAdapter{
int mGalleryItemBackground;
private Context mContext;
//get images from phone
public ArrayListUri getImageTable(){
ArrayListUri arrayList = new ArrayListUri();
try{
ContentResolver cr = getContentResolver();
String imageId = Media._ID;
Toast toast =
Toast.makeText(mContext,imageId,Toast.LENGTH_LONG);
toast.show();
String [] images = new String[]{imageId};
//Get Uri of ContentProvider MediaStore.Images.ImageColumns
Uri mediaUri = Thumbnails.EXTERNAL_CONTENT_URI;
Cursor managedCursor = managedQuery(mediaUri, images, null,
null, null);
startManagingCursor(managedCursor);
int columnIndex = managedCursor.getColumnIndexOrThrow(imageId);
for(int i=0;imanagedCursor.getCount();i++){
managedCursor.moveToPosition(i);
int id = managedCursor.getInt(columnIndex);
arrayList.add(Uri.withAppendedPath(mediaUri, +
imageId));
}
}catch(Exception e){
Toast toast =
Toast.makeText(mContext,e.toString(),Toast.LENGTH_LONG);
toast.show();
}
return arrayList;
}
public ImageAdapter(Context c){

return position;
}
@Override
public View getView(int position, View convertView, ViewGroup
parent) {
// TODO Auto-generated method stub
ImageView i = new ImageView(mContext);
//i.setImageResource(mImageIds[position]);
i.setImageURI(getImageTable().get(position));
i.setLayoutParams(new Gallery.LayoutParams(150, 100));
i.setScaleType(ImageView.ScaleType.FIT_XY);
i.setBackgroundResource(mGalleryItemBackground);
return i;
}
}
}

[android-developers] Gallery View with Text: Styling
I currently have a Gallery Widget very similar to Gallery2.java in the API examples. It is a gallery widget populated by a simple adaptor of text. What I am trying to do is make the selected (the item at the center of the gallery widget) text and background a certain color and the other visible items a different color. It should be a simple task, but I am unable to find a tutorial or the place in which to insert these options. Code which will modify the existing Gallery2.java to display the center item as Red for example whereas the other items remain the gray color would be very helpful. Many thanks in advance. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Gallery View using images from file (Dynamic vs. Static images)
The api demo for gallery uses resource id's to access the drawables in the gallery. I have tried multiple ways to use images from file. My steps... - 1. grab filepaths and save all files as a drawable array - 2. using the same logice in the api demo, I ste the background to the drawable instaed of the resid That's All I felt the need to replace from the api demo, which seems to fail miserably since the images do not appear in my test app. If you have any hints to help with this let me know, Thanks Billy Y --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
