Android View Pager deleting images from folder not refreshing

Whenever i delete my Image from my ViewPager. Then sometimes next Image will be deleted.or sometime's no image delete.
where i am wrong i dont know.
My GallaryActivity
public class GalleryActivity extends AppCompatActivity implements View.OnClickListener {
ImageButton imgBtnDelete;
TextView tvImageCount;
ViewPager galleryViewPager;
GalleryAdapter adapter;
private static String filePath = "";
public int mPosition = 0;
// File Code
public File mDirectory;
File[] imageList;
ArrayList<Integer> mTotalImages = new ArrayList<>();
ArrayList<String> mFilePaths = new ArrayList<>();
Uri[] mUrls;
String[] mFiles, mFileNames;
#Override

super.onCreate(savedInstanceState);
// Hide the Status bar...Write Before setContentView()
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
setContentView(R.layout.activity_gallery);
imgBtnDelete = (ImageButton) findViewById(R.id.imgBtnDelete);
imgBtnDelete.setOnClickListener(this);
// File Code
mDirectory = new File(android.os.Environment.getExternalStorageDirectory(), "CameraApp/Images");
imageList = mDirectory.listFiles(new FilenameFilter() {
#Override
public boolean accept(File file, String name) {
return ((name.endsWith(".jpg")) || (name.endsWith(".png")) || (name.endsWith(".mp4")));
}
});
int imgLength = (imageList == null) ? 0 : imageList.length;
if (imgLength > 0) {
mFiles = new String[imgLength];
// add imgLength here for set Total Images in TextView
for (int k = 0; k < imageList.length; k++) {
mTotalImages.add(imgLength);
filePath = imageList[k].getAbsolutePath();
mFilePaths.add(filePath);
}
mFileNames = new String[imgLength];
tvImageCount.setVisibility(View.VISIBLE);
tvImageCount.setText(1 + "/" + mTotalImages.size());
mUrls = new Uri[imgLength];
int i, j = 0;
for (i = imgLength - 1; i >= 0; i--) {
mFiles[j] = imageList[i].getAbsolutePath();
mFileNames[j] = imageList[i].getName();
j++;
}
galleryViewPager = (ViewPager) findViewById(R.id.galleryViewPager);
adapter = new GalleryAdapter(this, mFiles);
galleryViewPager.setAdapter(adapter);
galleryViewPager.setOnPageChangeListener(pageChangeListener);
} else {
tvImageCount.setVisibility(View.INVISIBLE);
Toast.makeText(this, "Please capture some images from App!", Toast.LENGTH_SHORT).show();
}
}
OnPageChangeListener pageChangeListener = new OnPageChangeListener() {
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
mPosition = position;
tvImageCount.setText((position + 1) + "/" + mTotalImages.size());
Toast.makeText(GalleryActivity.this, "mPosition is : " + mPosition, Toast.LENGTH_SHORT).show();
}
#Override
public void onPageScrollStateChanged(int state) {
}
};
private void openAlert() {
new AlertDialog.Builder(this)
.setTitle("Delete Image")
.setMessage("Are you sure you want to delete this Image?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
DeleteImage();
adapter.notifyDataSetChanged();
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
dialog.dismiss();
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
.setCancelable(true)
.show();
}
my DeleteImage()
private void DeleteImage() {
File file = new File(mFilePaths.get(mPosition));
boolean deleted = file.delete();
if (deleted) {
mFilePaths.remove(mPosition);
if (mFilePaths.size() == 0) {
tvImageCount.setVisibility(View.INVISIBLE);
}
if (mFilePaths.size() != 0 && mFilePaths.size() != 1) {
adapter.notifyDataSetChanged();
galleryViewPager.setCurrentItem(mPosition + 1);
}
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(file);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
} else {
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"
+ Environment.getExternalStorageDirectory())));
}
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.imgBtnDelete:
if (mDirectory.exists() && mDirectory != null && mFilePaths.size() != 0) {
openAlert();
} else {
Toast.makeText(this, "No Images to Delete!", Toast.LENGTH_SHORT).show();
}
break;
default:
break;
}
}
and following is my GallaryAdapter of Viewpager
public class GalleryAdapter extends PagerAdapter {
private Context mContext;
private String[] mFiles;
public GalleryAdapter(Context mContext, String[] mFiles) {
this.mContext = mContext;
this.mFiles = mFiles;
}
#Override
public int getCount() {
return mFiles.length;
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
LayoutInflater mLayoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = mLayoutInflater.inflate(R.layout.gallary_viewpager_item, container, false);
ImageView mImageView = (ImageView) itemView.findViewById(R.id.imgViewCenterGallery);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap;
bitmap = BitmapFactory.decodeFile(mFiles[position], options);
mImageView.setImageBitmap(bitmap);
container.addView(itemView);
return itemView;
}
public int getItemPosition(Object object) {
return PagerAdapter.POSITION_NONE;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
}

Try this way
if (imgLength > 0) {
mFiles = new String[imgLength];
mFileNames = new String[imgLength];
mUrls = new Uri[imgLength];
int j=0;
for (int i = imgLength-1; i >= 0; i--) {
mFiles[j] = imageList[i].getAbsolutePath();
mFileNames[j] = imageList[i].getName();
j++;
Toast.makeText(this, "Image Name - " + Arrays.toString(mFileNames), Toast.LENGTH_SHORT).show();
galleryViewPager = (ViewPager) findViewById(R.id.galleryViewPager);
adapter = new GallerySlideImageAdapter(this, mFiles, mFileNames);
galleryViewPager.setAdapter(adapter);
}
} else {
Toast.makeText(this, "Please capture some images from App !", Toast.LENGTH_SHORT).show();
}

Sort your file list as per latest to older datetime and bind files in adapter.
File[] files = directory.listFiles(); //your files object
Arrays.sort(files, new Comparator<File>(){
public int compare(File f1, File f2)
{
return Long.valueOf(f1.lastModified()).compareTo(f2.lastModified());
}
});

CustomAdapter is not displaying ArrayList Item: ImageView

In my CheckOutMemo.class I can set any title and content as shown in picture.
MainActivity.class then retrieves this title and content without any problems and displays a custom row. Like in this picture:
Title = Header
Content = bodyText
But the problem is: When I take a picture - I can't display it on my custom row. (That little dog in my MainActivity is there by default).
I don't know what the problem is.
I can preview my captured image as an Bitmap in my CheckOutMemo.class's contentView. I can successfully save it to my External Storage. But I can't display it on my MainActivity.

I've been working on this for over 2 months every day. Any help would be appreciated!!

Ok here is the minimal viable solution to get what you want. I just fixed it enough so an image is returned to your main activity. The rest of your issues are for you to fix. The only class I haven't touched is your Memo class. But that being said I highly recommend you update it to store a String with the path to the image instead of an ImageView.
But if for you what you want to do here are your files edited to work:
First custom adapter:
I've changed the lines where you get the image from memo, to check it's image view for a bitmap drawable and transfer that bitmap to the row's image view. There was no need to instantiate that CheckoutMemo activity here.
public class CustomAdapter extends BaseAdapter {
ArrayList<Memo> memos = new ArrayList<>();
public void add(Memo memo) {
this.memos.add(memo);
}
public void delete(int position) {
memos.remove(position);
}
#Override
public Memo getItem(int position) {
return memos.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public int getCount() {
return memos.size();
}
class MyViewHolder {
public TextView header, bodyText;
public ImageView imageView;
public MyViewHolder(View view) {
header = (TextView) view.findViewById(R.id.header);
bodyText = (TextView) view.findViewById(R.id.bodyText);
imageView = (ImageView) view.findViewById(R.id.primeImage);
}
}
#Override
public View getView(final int position, View convertView, ViewGroup parent){
MyViewHolder viewHolder;
if(null == convertView){

Next your CheckoutMemo:
I've changed how your setResult methods work. I've also deleted the method createImageFromBitmap. It was problematic, and also caused confusion. That one was a doozy. The createImageFromBitmap method was creating another MainActivity... confused me for a bit why onActivityResult wasn't being called. It wasn't being called because you were creating another activity =/
Anyways in your intent you create with your results, you'll notice I am also adding the file path string to the image created. So that main activity can use it to get the image!

In on activity result if the photo path exists. Then I am adding it to the memo object's image view to later be retrieved by the adapters ImageView. This can be upgraded a bit hence my comments above to be a little less convoluted by just passing the file path ;)

Keep at your project here. Two months is a good commitment. You are doing great, keep up the good work. There are more things you can improve in there! Just keep massaging it, and never give up.
You rock =)
I can get you the working project I've created to test this if needed.

First it seems you not using holder pattern in your CustomAdapter_back also as Fllo noticed you don't need to remove manually the views.
add this function to your adapter
public void setData(ArrayList<Damage_Item> data)
{
this.Damage_Item = Damage_Item;
notifyDataSetChanged();
}
and call this function from the dialog
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Whould you like to delete this image?");
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//get deleted item index according to your logic
int index = ((View) v.getParent()).getId() + 2;
gridArray.remove(index);
customGridAdapter.setData(gridArray);
Toast.makeText(getApplicationContext(), "delete", Toast.LENGTH_LONG).show();
}
});

in on activityResult you have a 2 lines of code:
customGridAdapter = new CustomAdapter_back(MainActivity.this, gridArray);
gridView.setAdapter(customGridAdapter);
so every single time when you are adding a new image you are recreating the adapter.
Just move adapter declaration to onCreate with empty list.
Add method
public void addItem(Damage_Item item){
this.Damage_Item.add(item);
this.notifyDataSetChange();
}
to your adapter and trigger it instead of creating adapter and setting new inside your onCaptureImageResult.
And for god sake, naming convention. Your code is unreadable

Try this
public class MainActivity extends Activity implements AdapterView.OnItemClickListener {
GridView gridView;
ArrayList<Damage_Item> gridArray = new ArrayList<Damage_Item>();
CustomAdapter_back customGridAdapter;

Try changing your xml by removing the GridView as the gridlayout should change the size of the image automatically.
Another non-recommended solution would be to use the screen dimensions for sizing your image

Store the images picked from gallery android

I want to click the "btnchooserphoto" button to pick the images from gallery and
I can do it now, but I want to store these images and when I click "btnchooserphoto" button again I can add another images and the images I picked are still there. But now the ImageLoader will re-init everytime... log is below
W/ImageLoader(4503): Try to initialize ImageLoader which had already been initialized before. To re-init ImageLoader with new configuration call ImageLoader.destroy() at first.
Can anybody know how to fix it? thanks!!!
