I am facing with a problem which happens only when I add new drawable.
I have a parsed xml to Fragment the icon is set like int. If I add new drawable then it chooses random drawables to show the icons for the parsed xml.
I have an Adapter for the RecyclerListView.
A Pojo class and DB which extends SQLiteOpenHelper.
If I clear the cache and Storage then it back to normal, or if I delete the new added drawable it returns back to normally.
Can someone help me to know why it is affecting to change the icons.
I have tried to clean project and rebuild the same. Invalidate cache and restart but still the same.
Below you can find the code and below the code two pictures of the problem.
public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private static final int ITEM_TYPE_ONE = 0;
private static final int ITEM_TYPE_TWO = 1;
private final Handler handler = new Handler();
private final ArrayList<Bookmark> arrayList;
private final String BASE_URL = "https://besticon-demo.herokuapp.com/icon?url=";
private final Context context;
public MyAdapter(Context context, ArrayList<Bookmark> arrayList) {
this.context = context;
this.arrayList = arrayList;
}
@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = null;
if (viewType == ITEM_TYPE_ONE) {
view = LayoutInflater.from(context).inflate(R.layout.grid_item, parent, false);
return new ViewHolder(view);
} else if (viewType == ITEM_TYPE_TWO) {
view = LayoutInflater.from(context).inflate(R.layout.add_bookmark, parent, false);
return new ButtonViewHolder(view);
} else {
return null;
}
}
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, final int position) {
final int itemType = getItemViewType(position);
final Bookmark bookmark = this.arrayList.get(position);
if (itemType == ITEM_TYPE_ONE) {
final ViewHolder viewHolder = (ViewHolder) holder;
RequestOptions requestOptions = new RequestOptions();
BookmarkDB bookmarkDB = new BookmarkDB(context);
String imageUrl = BASE_URL + arrayList.get(position).getSearchUrl() + "&size=32";
int resID = context.getResources().getIdentifier(String.valueOf(arrayList.get(position).getIcon()), "drawable", context.getPackageName());
if (resID == 0) {
Glide.with(context)
.load(imageUrl)
.apply(requestOptions
.placeholder(R.drawable.default_favicon)
.diskCacheStrategy(DiskCacheStrategy.AUTOMATIC)
.fitCenter())
.into(viewHolder.tvIcon);
} else {
viewHolder.tvIcon.setImageResource(resID);
String imageName = context.getResources().getResourceName(resID);
Log.d("getIcons", imageName); // This is the log.
} else if (itemType == ITEM_TYPE_TWO) {
ButtonViewHolder buttonViewHolder = (ButtonViewHolder) holder;
buttonViewHolder.imgButton.setImageResource(arrayList.get(position).getIcon());
}
}
class ViewHolder extends RecyclerView.ViewHolder {
final ImageView tvIcon;
ViewHolder(@NonNull final View itemView) {
super(itemView);
tvIcon = itemView.findViewById(R.id.image_view);
}
}
The Bookmark.db
public class BookmarkDB extends SQLiteOpenHelper {
private static final String DBNAME = "bookmarks.db"; // The name of the database file
private static final int DBVERSION = 1; // The Database version
public static final String TBL_BOOKMARK = "bookmark";
private static final String COL_ICON = "icon";
private final SQLiteDatabase mDB;
Context mContext;
public BookmarkDB(Context context) {
super(context, DBNAME, null, DBVERSION);
mDB = this.getWritableDatabase();
}
@Override
public void onCreate(SQLiteDatabase db) {
// The SQL to be used to create the table
String crt_bookmark_tbl_sql = "CREATE TABLE IF NOT EXISTS " + TBL_BOOKMARK + "(" +
COL_ICON + " TEXT, " +
")";
db.execSQL(crt_bookmark_tbl_sql); // CREATE THE TABLE
}
public ArrayList<Bookmark> getAllBookmarks() {
ArrayList<Bookmark> rv = new ArrayList<>();
Cursor csr = mDB.query(TBL_BOOKMARK, null, null, null, null, null, null);
while (csr.moveToNext()) {
Bookmark b = new Bookmark();
int Icon = csr.getInt(csr.getColumnIndex(COL_ICON));
rv.add(b);
}
return rv;
}
This is the .XML file.

Fragment of RecyclerView

This is layout of Fragment.
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="wrap_content"
android:overScrollMode="never">

android:layout_width="match_parent"
android:layout_height="match_parent"

app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent">
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.NestedScrollView>
I have created a LogCat to show what it takes this is the result.
Right way
drawable/youtube
drawable/facebook
drawable/twitter
After add drawable or vector asset or image
drawable/wiki
drawable/facebook
drawable/trash
from Adding a new drawable it is changing the icons of the parsed xml
