The checked Gridview position changes on scrolling

The checked Gridview position changes on scrolling - android

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);
setResult(Activity.RESULT_OK, i);
finish();
}
}
});
}
public class ImageAdapter extends BaseAdapter {

public ImageAdapter(String[] arrPath) {

} else {

}
holder.chkImage.setId(position);

holder.imgThumb.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

android from app select multiple photos, but not gallery images

From the many previous posts I can now have my app launch the Intent which will allow the users to select multiple images.
But the Intent presents both Gallery Images and Photos when I want Photos only.
The Gallery Images are of no use and merely confuse the user.
So my question is how to limit the images presented to the user for selection to Only the Photos and Not the Gallery.
The code I am currently using is as follows:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.galleryimagepicker);
lnrImages = (LinearLayout)findViewById(R.id.lnrImages);
btnAddPhotos = (Button)findViewById(R.id.btnAddPhotos);
btnAddPhotos.setOnClickListener(this);
btnSaveImages = (Button)findViewById(R.id.btnSaveImages);
btnSaveImages.setOnClickListener(this);
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.btnAddPhotos:
/*Intent intent = new Intent(GalleryImagePicker.this,CustomPhotoGalleryActivity.class);
startActivityForResult(intent,PICK_IMAGE_MULTIPLE);*/
Intent intent = new Intent(GalleryImagePicker.this,CustomPhotoGalleryActivity.class);
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent,PICK_IMAGE_MULTIPLE);
break;
case R.id.btnSaveImages:
if(imagesPathList != null)
{
if(imagesPathList.size() >= 1) {
//Toast.makeText(GalleryImagePicker.this, imagesPathList.size() + " no of images are selected", Toast.LENGTH_SHORT).show();
String[] stringArray = imagesPathList.toArray(new String[0]);
for (int i = 0; i < stringArray.length; i++){
String ThisImgPath = stringArray[i];
String PicName = ThisImgPath;
if (SystemIOFile.exists(PicName)) {
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inSampleSize = 4;
Bitmap bm = BitmapFactory.decodeFile(ThisImgPath, bmOptions);
Uri ThisUri = getImageUri(cntxt, bm);
bm = decodeBitmap(cntxt, ThisUri, bmOptions.inSampleSize);
Boolean HOLD = true;
}
Boolean HOLD = true;
}
}else{
Toast.makeText(GalleryImagePicker.this, imagesPathList.size() + " no of image are selected", Toast.LENGTH_SHORT).show();
}
}
else
{
Toast.makeText(GalleryImagePicker.this," no images are selected", Toast.LENGTH_SHORT).show();
}
break;
}
}

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 .
