I am trying to design a custom gallery for android. I am able to display images, but something is going wrong with Videos. I am new to Android, any help would be appreciated :)
The issue is I have two data source one for Images and other for Videos, so how to merge both the data and display together.
Code:
public class MainActivity extends Activity {
private int count;
private int vcount;
private Bitmap[] thumbnails;
private String[] arrPath;
private Bitmap[] vthumbnails;
private String[] varrPath;
private ImageAdapter imageAdapter;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//sets UI of main page from activity_main.xml
setContentView(R.layout.activity_main);
//get images from SD card and sort
final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };
final String orderBy = MediaStore.Images.Media.DATE_TAKEN;
Cursor imagecursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null,null, orderBy + " DESC");
//this.imageUrls = new ArrayList<String>();
int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media._ID);
this.count = imagecursor.getCount();
this.thumbnails = new Bitmap[this.count];
this.arrPath = new String[this.count];
for (int i = 0; i < this.count; i++) {
imagecursor.moveToPosition(i);
int id = imagecursor.getInt(image_column_index);
int dataColumnIndex = imagecursor.getColumnIndex(MediaStore.Images.Media.DATA);
thumbnails[i] = MediaStore.Images.Thumbnails.getThumbnail(
getApplicationContext().getContentResolver(), id,
MediaStore.Images.Thumbnails.MICRO_KIND, null);
arrPath[i]= imagecursor.getString(dataColumnIndex);
}
final String[] parameters = { MediaStore.Video.Media._ID,
MediaStore.Video.Media.DATA,
MediaStore.Video.Media.DISPLAY_NAME,
MediaStore.Video.Media.SIZE, MediaStore.Video.Media.DURATION,
MediaStore.Video.Media.DATE_TAKEN,MediaStore.Video.Thumbnails.DATA};
//final String vOrderBy = MediaStore.Video.Media.DATE_TAKEN;
Cursor videocursor = getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,parameters, null, null, null);
int video_column_index = videocursor.getColumnIndex(MediaStore.Video.Media._ID);
this.vcount = videocursor.getCount();
this.vthumbnails = new Bitmap[this.vcount];
this.varrPath = new String[this.vcount];
for (int j = 0; j < this.vcount; j++) {
videocursor.moveToPosition(j);
int id = videocursor.getInt(video_column_index);
int vDataColumnIndex = videocursor.getColumnIndex(MediaStore.Video.Media.DATA);
vthumbnails[j] = MediaStore.Video.Thumbnails.getThumbnail(
getApplicationContext().getContentResolver(), id,
MediaStore.Video.Thumbnails.MICRO_KIND, null);
varrPath[j]= videocursor.getString(vDataColumnIndex);
}
GridView imagegrid = (GridView) findViewById(R.id.PhoneImageGrid);
imageAdapter = new ImageAdapter();
imagegrid.setAdapter(imageAdapter);
//imagecursor.close();
}
public class ImageAdapter extends BaseAdapter {
private LayoutInflater mInflater;
public ImageAdapter() {
mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return count;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.galleryitem, null);
holder.imageview = (ImageView) convertView.findViewById(R.id.thumbImage);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
holder.imageview.setId(position);
holder.imageview.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//TODO Auto-generated method stub
int id = v.getId();
Intent intent = new Intent(MainActivity.this,Lastscreen.class);
intent.setDataAndType(Uri.parse("file://" + arrPath[id]), "image/*");
intent.putExtra("path", arrPath[id]);
startActivity(intent);
}
});
holder.imageview.setImageBitmap(thumbnails[position]);
return convertView;
}
}
class ViewHolder {
ImageView imageview;
}
}
You have to show only images in the Grid view.
Corresponding videos should stored in SD card
Image file names and video file names
First get the image names in arraylist and get the video names another arraylist, then compare it and get the data.
Thanks

I have already tried the suggestions which are there on this site and they dont work for me. I will try to be very precise. I have a Custom gallery which displays images in gridview. The user can select multiple images from the gridview. Once the Gridview position is clicked the "Tick" icon is displayed on that position to notify user that the image has been selected. The problem is when i select an image and scroll the "Ticked" icon which was on the selected image appears on some other image.Here is the code.
public class CustomPhotoGalleryActivity extends Activity {
private GridView grdImages;
private Button btnSelect;
private ImageAdapter imageAdapter;
private String[] arrPath;
private boolean[] thumbnailsselection;
private int ids[];
private int count;
private Cursor imagecursor = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.custom_gallery);
grdImages = (GridView) findViewById(R.id.grdImages);
btnSelect = (Button) findViewById(R.id.btnSelect);
final String[] columns = {MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID};
final String orderBy = MediaStore.Images.Media._ID;
imagecursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null, null, orderBy);
int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media._ID);
this.count = imagecursor.getCount();
this.arrPath = new String[this.count];
ids = new int[count];
this.thumbnailsselection = new boolean[this.count];
for (int i = 0; i < this.count; i++) {
imagecursor.moveToPosition(i);
ids[i] = imagecursor.getInt(image_column_index);
int dataColumnIndex = imagecursor.getColumnIndex(MediaStore.Images.Media.DATA);
arrPath[i] = imagecursor.getString(dataColumnIndex);
Log.e("arrPath", "" + arrPath[i]);
}
imageAdapter = new ImageAdapter(arrPath);
grdImages.setAdapter(imageAdapter);
btnSelect.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
final int len = thumbnailsselection.length;
int cnt = 0;
String selectImages = "";
for (int i = 0; i < len; i++) {
if (thumbnailsselection[i]) {
cnt++;
selectImages = selectImages + arrPath[i] + "|";
}
}
if (cnt == 0) {
Toast.makeText(getApplicationContext(), "Please select at least one image", Toast.LENGTH_LONG).show();
} else {
Log.d("SelectedImages", selectImages);
Intent i = new Intent();
i.putExtra("data", selectImages);

finish();
}
}
});

don't save the image , Just save image path on the database.
The easiest ways :
1-don't save the image , Just save image path on the database as string value .
2-convert the image to bitmap and save it in the database.
I prefer the first solution .
I want to fetch all images in my application from android photo gallery .because I want to load an image into my application again after saving it into android gallery .
For Saving my image into gallery I use below method.
MediaStore.Images.Media.insertImage(ContentResolverObj, bitMap, "uniqueTitle", "description");
Now programatically I want to fetch all images into my application and want to get above saved image on the basis of tile.Two questions here.
1st:Can I fetch all images from photo gallery of android ?
2nd:can I read single photo detail like title etc after fetching it.
by using this code i am able to display phone gallery images in gridview, depending on your requirement change this..
public class MyPhoneGallery extends Activity {
/** Called when the activity is first created. */
private Cursor imagecursor, actualimagecursor;
private int image_column_index, actual_image_column_index;
GridView imagegrid;
private int count;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gallery);
init_phone_image_grid();
}
private void init_phone_image_grid() {
String[] img = { MediaStore.Images.Thumbnails._ID };
imagecursor = managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, img, null,null, MediaStore.Images.Thumbnails.IMAGE_ID + "");
image_column_index = imagecursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
count = imagecursor.getCount();
imagegrid = (GridView) findViewById(R.id.PhoneImageGrid);
imagegrid.setAdapter(new ImageAdapter(getApplicationContext()));
imagegrid.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,int position, long id) {
System.gc();
String[] proj = { MediaStore.Images.Media.DATA };
actualimagecursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj,null, null, null);
actual_image_column_index = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
actualimagecursor.moveToPosition(position);
String i = actualimagecursor.getString(actual_image_column_index);
System.gc();
Intent intent = new Intent(getApplicationContext(), ViewImage.class);
intent.putExtra("filename", i);
startActivity(intent);
}
});
}
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context c) {
mContext = c;
}
public int mygetItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
public int getCount() {
return count;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position,View convertView,ViewGroup parent) {
System.gc();
ImageView i = new ImageView(mContext.getApplicationContext());
if (convertView == null) {
imagecursor.moveToPosition(position);
int id = imagecursor.getInt(image_column_index);
i.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ id));
i.setScaleType(ImageView.ScaleType.CENTER_CROP);
i.setLayoutParams(new GridView.LayoutParams(125, 125));
}
else {
i = (ImageView) convertView;
}
return i;
}
}
}
I used this code and got image, maybe it works for you
final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };
final String orderBy = MediaStore.Images.Media._ID;
imagecursor = getActivity().managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null, null, orderBy);
int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media._ID);
this.count = imagecursor.getCount();
this.arrPath = new String[this.count];
ids = new int[count];
for (int i = 0; i < this.count; i++) {
imagecursor.moveToPosition(i);
ids[i] = imagecursor.getInt(image_column_index);
int dataColumnIndex = imagecursor.getColumnIndex(MediaStore.Images.Media.DATA);
arrPath[i] = imagecursor.getString(dataColumnIndex);
}
