안녕하세요 안드로이드 초보개발자입니다.
recyclerview를 사용하던 중 의문점이 발생해서 이렇게 글 남깁니다.
debug로 올린 앱에서는 문제없이 작동하는데 release로 올리게 되면
header view가 안보이고 item들이 중복되서 나타나는 현상을 겪고 있습니다.
혹시 비슷한 경험을 하셨거나 해결 방안을 아시는 분은 조언 부탁드립니다. ㅠㅠ
아래 코드는 adapter 부분 코드입니다.
public ThermometerScanAdapter(Context context, Class<? extends RecyclerView.ViewHolder> clazz,
List<BluetoothDevice> data, Map<String, Integer> rssiMap){
this.mLayoutInflator = LayoutInflater.from(context);
this.mBodyHolderClazz = clazz;
this.mData = data;
this.mRssiMap = rssiMap;
this._HEADER_ENABLE = BuildConfig.DEBUG ? 1 : 0;
this._EMPTY_ENABLE = 1;
cSignalFine = ActivityCompat.getColor(context, R.color.scanSignalFine);
cSignalPoor = ActivityCompat.getColor(context, R.color.scanSignalPoor);
}
@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
if(viewType == VIEW_TYPE_BODY){
if(ThermometerScanHolder.class.equals(mBodyHolderClazz)){
View v = mLayoutInflator.inflate(ThermometerScanHolder.LAYOUT_RES, parent, false);
return new ThermometerScanHolder(v);
}
else if(ScannerScanHolder.class.equals(mBodyHolderClazz)){
View v = mLayoutInflator.inflate(ScannerScanHolder.LAYOUT_RESOURCE, parent, false);
return new ScannerScanHolder(v);
}
}
else if(viewType == VIEW_TYPE_HEADER){
View v = mLayoutInflator.inflate(ScanHeaderHolder.LAYOUT_RES, parent, false);
return new ScanHeaderHolder(v);
}
