私は3つのRecyclerView
を持っていて、3つすべてスクロールで遅れています。私は多くのことをインターネットで提案しようとしましたが、何も私のRecyclerView
を速くしませんでした。私は下記の解決策を試してみましたRecyclerViewがスクロールで遅れている
、
そして、いくつかのより多くの
-
。それらのうちのいくつかは関連性がありません。しかしそれでも、それは遅れます。
参考のため、以下はRecyclerView
の画像です。ビューの
xml

は、ここでは、アダプタ
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
holder.setIsRecyclable(false);
if (holder instanceof HeaderViewHolder) {
HeaderViewHolder transactionViewHolder = (HeaderViewHolder) holder;
String getTodayDate = (String) filteredList.get(position);
transactionViewHolder.setDate(DateUtility.getFormattedDate(getTodayDate));
} else if (holder instanceof MainViewHolder) {
MainViewHolder viewHolder = (MainViewHolder) holder;
try {
final History history = (History) filteredList.get(position);
viewHolder.setTransaction(history, mContext);
} catch (Exception e){
e.printStackTrace();
}
}
}
そして、私は他の2 RecyclerView
Sを最適化するのに役立つかもしれViewHolder
private void setTransaction(final History history, final Context context){
String myId = new Session(context).getStringForKey(Session.prIdKey);
if(history.getTo().equals(history.getFrom())) {

break;

break;

messageStatusImageSelf.setImageResource(R.drawable.ic_transaction_status_done);
break;
}
LinkedBank associatedBank = history.getSenderBank();
bankNameSelf.setText(associatedBank.fetchAbbreviationAndAccountNumber());
if(history.getReceiverNotes() != null && history.getReceiverNotes().length() > 0) {
separatorNoteSelf.setVisibility(View.VISIBLE);
layoutNoteSelf.setVisibility(View.VISIBLE);
textNoteSelf.setText(history.getReceiverNotes());
} else if(history.getSenderNotes() != null && history.getSenderNotes().length() > 0) {
separatorNoteSelf.setVisibility(View.VISIBLE);
layoutNoteSelf.setVisibility(View.VISIBLE);
textNoteSelf.setText(history.getSenderNotes());
}
transactionSelf.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
((OnIndividualTransactionSelection) context).onTransactionSelected(history);
}
});
} else if(history.getFrom().equals(myId)) {

Picasso.with(context).load(associatedBank.getBankLogo()).placeholder(R.drawable.placeholder_default).error(R.drawable.placeholder_default).into(bankLogoOut);
transactionOut.setOnClickListener(new View.OnClickListener() {

});
} else if(history.getTo().equals(myId)) {

transactionIn.setOnClickListener(new View.OnClickListener() {

}
}
それの答えのsetTransaction
方法ですです。どんな助けも高く評価されます。
回答ありがとうございますが、私は何をどのように削減するか提案が必要ですか?私はすでにコードを何度も読んでいて、何も見つけられませんでした。これは実際にチャットバブルを表示するためのもので、3つのタイプがあります。また、「RecyclerView」には合計4つのビューがあります。何を提案しますか? –
