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();

System.gc();

startActivity(intent);
}
});
}

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.setLayoutParams(new GridView.LayoutParams(125, 125));
}

}
}
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);
}

I tried to make a list of videos, everything was right, the list is shown and you can see in videoview. but.
1) How can I add bitmap image in the list of videos?
2) How can I change the ListView, with Gridview?
Thank you

How to get thumbnails from a specific folder in sd card. I am using this tutorial http://gypsynight.wordpress.com/2012/02/17/how-to-show-all-video-file-stored-in-your-sd-card-in-a-listview/
It can be done easily this way:
int videoId = videoCursor.getInt(videoCursor.getColumnIndexOrThrow(MediaStore.Video.Media._ID));
ContentResolver cr = getContentResolver();
BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 1;
Bitmap curThumb = MediaStore.Video.Thumbnails.getThumbnail(cr, videoId, MediaStore.Video.Thumbnails.MICRO_KIND, options);
thumbImage.setImageBitmap(curThumb);
I have a gridview in one screen and in gridview i am displaying all the images which is present in SDCard this is working fine. Now what i want to do is when i click on any of gridview images it should go to next activity and should display that particular image in full screen. I have referred some other link and tried but not getting proper solution.
public class Gallary_Images extends Activity {
private Cursor cursor;

This is my gridview class where i am calling next activity. Now i don't know how should i get the images in next activity. Please help...
First thing that you must try is a put an URi of image in your intent like this
intent.putExtra("imageUri", imageUri.toString());
where imageUri is Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ imageID));
but before this you must know your imageID, so the whole code must be like this
sdcardImages.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position,long id) {
Intent i = new Intent(getApplicationContext(),ViewGallery_Photo.class);
cursor.moveToPosition(position);
int imageID = cursor.getInt(columnIndex);
Uri imageUri = Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
""+ imageID));
intent.putExtra("imageUri", imageUri.toString());
startActivity(i);
}
});
Try out as below:
Add data filed in your projection string.
String[] columns = { MediaStore.Images.Media.DATA,
MediaStore.Images.Media._ID };
public void onItemClick(AdapterView<?> arg0, android.view.View v,
int position, long id) {
Intent i = new Intent(getApplicationContext(),ViewGallery_Photo.class);
cursor = managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns,
null, null, null);
final int dataColumnIndex = cursor
.getColumnIndex(MediaStore.Images.Media.DATA);
final int idColumIndex = actualimagecursor
.getColumnIndex(MediaStore.Images.Media._ID);
cursor.moveToPosition(position);
filename = cursor.getString(dataColumnIndex);
i.putExtra("imagePath", filename );
startActivity(i);
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

//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,

arrPath[i]= imagecursor.getString(dataColumnIndex);
}
final String[] parameters = { MediaStore.Video.Media._ID,

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) {

}
public View getView(int position, View convertView, ViewGroup parent) {

if (convertView == null) {

}
else {

}
});

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
Here is my image gallery code. So far, for testing purpose I directly used some manually stored images,
public class Photo_Gallery extends Activity
{
//---the images to display---
Integer[] imageIDs = {
R.drawable.a,
R.drawable.b,
R.drawable.c,
R.drawable.d,
R.drawable.e,
};
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.displayview);
Gallery gallery = (Gallery) findViewById(R.id.gallery1);
gallery.setAdapter(new ImageAdapter(this));
gallery.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView parent, View v, int position, long id)
{
//---display the images selected---
ImageView imageView = (ImageView) findViewById(R.id.image1);
imageView.setImageResource(imageIDs[position]);
}
});
}
public class ImageAdapter extends BaseAdapter
{
private Context context;
private int itemBackground;
public ImageAdapter(Context c)
{
context = c;
//---setting the style---
TypedArray a = obtainStyledAttributes(R.styleable.Gallery1);
itemBackground = a.getResourceId(
R.styleable.Gallery1_android_galleryItemBackground, 0);
a.recycle();
}
//---returns the number of images---
public int getCount() {
return imageIDs.length;
}
//---returns the ID of an item---
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
//---returns an ImageView view---
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(context);
imageView.setImageResource(imageIDs[position]);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setLayoutParams(new Gallery.LayoutParams(75, 60));
imageView.setBackgroundResource(itemBackground);
return imageView;
}
}
}
And here is the code I used to capture images.
case R.id.takeSnapBtn:
try {
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, imageData);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Following is the onActivityResult(),
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
bmp = (Bitmap) extras.get("data");
imageView.setImageBitmap(bmp);
}
}
I would be glad if some one provide me an example of how to dynamically update the gallery with images taken from the camera.
Store the images captured from app and read those images from sd card to gallery..
File sdDir = new File("/sdcard/Pictures/YOUR_DIR");
sdDirFiles = sdDir.listFiles();
for (i = 0; i < sdDirFiles.length; i++) {
//ADD to gallery HERE..
}
If u get all images under the sdcard of perticular Bucket(folder) then use this code...
public class SubGalleryView extends Activity {
private ArrayList<Integer> ImageIds = new ArrayList<Integer>();
private GridView subGalleryView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sub_gallery_view);
//Provide Bucket_Name/Folder_Name Using Bundle.
Bundle bundle = getIntent().getExtras();
Toast.makeText(this, bundle.getString("Bucket_Name"),
Toast.LENGTH_SHORT).show();
//Using Projection We get all images of all folder.
String[] projection = new String[] { MediaStore.Images.Media._ID,
MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME };
Cursor cursor = managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, null,
null, null);
cursor.moveToFirst();
if (cursor.getCount() > 0) {
//using this do{}while(); we get all image_id under perticular bucket. and strored in ArrayList of ImagesIds.
do {
int columnIndex = cursor
.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME);
if (cursor.getString(columnIndex).equalsIgnoreCase(
bundle.getString("Bucket_Name"))) {
columnIndex = cursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
int imageID = cursor.getInt(columnIndex);
ImageIds.add(imageID);
} else if (bundle.getString("Bucket_Name").equalsIgnoreCase(
"All Pictures")) {
columnIndex = cursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
int imageID = cursor.getInt(columnIndex);
ImageIds.add(imageID);
}
} while (cursor.moveToNext());
}
//Pass ImageIds arrayList to Adapter.
subGalleryAdapter imageAdapter = new subGalleryAdapter(
SubGalleryView.this, R.layout.sub_gallery_view_item, ImageIds);
subGalleryView = (GridView) findViewById(R.id.subGallery);
subGalleryView.setAdapter(imageAdapter);
}
public class subGalleryAdapter extends ArrayAdapter<Integer> {
private Context contex;
private int resourceId;
private LayoutInflater layoutInflater = null;
private ArrayList<Integer> mlist;
public subGalleryAdapter(Activity context, int resourceId,
ArrayList<Integer> list) {
super(context, resourceId, list);
this.mlist = list;
this.contex = context;
this.resourceId = resourceId;
this.layoutInflater = context.getLayoutInflater();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView viewHolder;
if (convertView == null) {
viewHolder = new ImageView(contex);
convertView = layoutInflater.inflate(resourceId, parent, false);
viewHolder = (ImageView) convertView
.findViewById(R.id.imageView1);
} else {
viewHolder = (ImageView) convertView
.findViewById(R.id.imageView1);
}
viewHolder.setImageURI(Uri.withAppendedPath(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
"" + mlist.get(position)));
return convertView;
}
}
}
Using this code u get all images from perticular folder passing bucket display name in bundle. and if u get all images of all bucket(folder) form sdcard then use this code
public class SubGalleryViewy extends Activity {
private Cursor cursor;
private int columnIndex;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sdcard);
// Set up an array of the Thumbnail Image ID column we want

null, // Return all rows
null,
MediaStore.Images.Thumbnails.IMAGE_ID);
// Get the column index of the Thumbnails Image ID
columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
GridView sdcardImages = (GridView) findViewById(R.id.sdcard);
sdcardImages.setAdapter(new ImageAdapter(this));
// Set up a click listener
sdcardImages.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id) {
// Get the data location of the image
String[] projection = {MediaStore.Images.Media.DATA};
cursor = managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection, // Which columns to return
null, // Return all rows
null,
null);
columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToPosition(position);
// Get image filename
String imagePath = cursor.getString(columnIndex);
// Use this path to do further processing, i.e. full screen display
}
});
}
