ApiClient.getClient（）。create（ApiInterface.class）は、Retrofitクライアントを常に再作成するよう呼び出されています。 （同じことがrecyclerViewにも当てはまります）。私はシングルトンを使うべきだと思っています.Android Studioでどのように見つけられたのでしょう？ここに私のコードは次のとおりです。Androidオブジェクトの作成と初期化に関するいくつかの問題
public void fetchData() {
ApiInterface apiService =
ApiClient.getClient().create(ApiInterface.class);
Call<List<Currency>> call = apiService.getData("");
if (isNetworkAvailable()) {
call.enqueue(new Callback<List<Currency>>() {
@Override
public void onResponse(Call<List<Currency>> call, Response<List<Currency>> response) {
if (response.isSuccessful()) {
List<Currency> rew = response.body();
if((moduloLoop % 2) == 0) {
for (int i =0; i < rew.size(); i++){
mBuy.add(i, String.valueOf(rew.get(i).getBuy())+","+i);
mSell.add(i, String.valueOf(rew.get(i).getSell())+","+i);
mSharePreference.saveArray(MainActivity.this, mBuy,"BuyValue");
mSharePreference.saveArray(MainActivity.this, mSell,"SellValue");
}
mSell.clear();
mBuy.clear();
}
if(!isTablet){
recyclerView.setAdapter(new CurrencyAdapter(response.body(), R.layout.list_item_trade, MainActivity.this));
}else {
recyclerView.setAdapter(new CurrencyAdapter(response.body(), R.layout.tablet_list_item_trade, MainActivity.this));
}
} else {
alertError(MainActivity.this.getString(R.string.DownloadFailed));
}
}
@Override
public void onFailure(Call<List<Currency>> call, Throwable t) {
alertError(t.getMessage()+"");
}
});
}else {
alertError(this.getString(R.string.network_unavailable));
}
}
