I wrote a image attaching code as shown below:
Recycler view:
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/gv_attach_image"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginTop="16dp"
android:layout_marginEnd="8dp"
android:nestedScrollingEnabled="true"
android:numColumns="3"
android:visibility="gone" />
My Java code:
RecyclerView attachImageGV;
GalleryRecycleViewAdapter galleryAdapter;
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
try {
if (resultCode == RESULT_OK) {
if (requestCode == PICK_FROM_GALLERY && data != null) {
String[] strings = {MediaStore.Images.Media.DATA};
imageEncodeList = new ArrayList<>();
ArrayList<Uri> uris = new ArrayList<>();
attachImageGV.setVisibility(View.VISIBLE);
if (data.getData() != null) {
Uri uri = data.getData();
String selectedFilePath = FilePath.getPath(mContext, uri);
imageEncodeList.add(selectedFilePath);
// Cursor cursor = mContext.getContentResolver().query(uri, strings, null, null, null);
// cursor.moveToFirst();
// int columnIndex = cursor.getColumnIndex(strings[0]);
// imageEncoded = cursor.getString(columnIndex);
// cursor.close();
uris.add(uri);
galleryAdapter.addImage(uri);
} else {
if (data.getClipData() != null) {
ClipData clipData = data.getClipData();
for (int i = 0; i < clipData.getItemCount(); i++) {
ClipData.Item item = clipData.getItemAt(i);
Uri uri = item.getUri();
String selectedFilePath = FilePath.getPath(mContext, uri);
//Cursor cursor = mContext.getContentResolver().query(uri, strings, null, null, null);
// cursor.moveToFirst();
// int columnIndex = cursor.getColumnIndex(strings[0]);
// imageEncoded = cursor.getString(columnIndex);
imageEncodeList.add(selectedFilePath);
// cursor.close();
uris.add(uri);
galleryAdapter.addImage(uri);
}
Log.d("Report issue", "onActivityResult: Number of Selected Images" + imageEncodeList.size());
}
}
} else {
Toast.makeText(mContext, "You've not attached any image!", Toast.LENGTH_LONG).show();
}
}
} catch (Exception e) {
e.printStackTrace();
Log.e(TAG, "onActivityResult, error is: ", e);
Toast.makeText(mContext, "Something went wrong", Toast.LENGTH_SHORT).show();
}
super.onActivityResult(requestCode, resultCode, data);
}
Gallery adapter:
class GalleryRecycleViewAdapter : RecyclerView.Adapter<GalleryRecycleViewAdapter.ViewHolder> {
var mContext: Context
var mArrayList = ArrayList<Uri>()
lateinit var onItemClickListener: OnItemClickListener
//Below we are limiting the number of items on home screen
private var limit = 0
constructor(context: Context, onItemClickListener: OnItemClickListener) {
this.mContext = context
this.onItemClickListener = onItemClickListener;
}
constructor(context: Context) {
this.mContext = context
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val binding = DataBindingUtil.inflate<GalleryviewerBinding>(LayoutInflater.from(parent.context),
R.layout.galleryviewer, parent, false)
return ViewHolder(binding)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
holder.binding.ivGallery.setImageURI(mArrayList.get(position));
holder.binding.ivRemoveAttach.setOnClickListener {
mArrayList.removeAt(position)
notifyDataSetChanged()
}
}
override fun getItemCount(): Int {
/* return if (mArrayList != null) {
if (limit > 0) {
if (mArrayList.size > limit) {
limit
} else {
mArrayList.size
}
} else {
mArrayList.size
}
} else 0*/
return mArrayList.size
}
fun addImage(uri: Uri) {
this.mArrayList.add(uri)
notifyDataSetChanged()
}
inner class ViewHolder(internal var binding: GalleryviewerBinding) : RecyclerView.ViewHolder(binding.root)
companion object {
private val TAG = "EventsRecyclerViewAdapt"
}
fun getMarrayList(): ArrayList<Uri> {
return mArrayList
}
}
What am I missing?
