我试图简单地显示标准普尔和纳斯达克指数的价格。出于某种原因，我的应用程序仍然崩溃。该代码在Eclipse中工作，而不是在Android Studio中。任何帮助将不胜感激。这是我的片段：
package com.capstone.hammond.wallstreetfantasyleaguefinal;
import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import java.math.BigDecimal;
import yahoofinance.Stock;
import yahoofinance.YahooFinance;
public class HomeFragment extends Fragment {
public static String spPriceS;
public static String spPercentS;
public static String nasdaqPriceS;
public static String nasdaqPercentS;
View rootview;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
rootview = inflater.inflate(R.layout.fragment_home, container, false);
return rootview;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
yahoofinance.Stock stockOne = YahooFinance.get("^GSPC");
BigDecimal spPriceBD = stockOne.getQuote().getPrice();
HomeFragment.spPriceS = spPriceBD.toString();
BigDecimal spPercentBD = stockOne.getQuote().getChangeInPercent();
HomeFragment.spPercentS = spPercentBD.toString();
yahoofinance.Stock stockTwo = YahooFinance.get("^IXIC");
BigDecimal nasdaqPriceBD = stockTwo.getQuote().getPrice();
HomeFragment.nasdaqPriceS = nasdaqPriceBD.toString();
BigDecimal nasdaqPercentBD = stockTwo.getQuote().getChangeInPercent();
HomeFragment.nasdaqPercentS = nasdaqPercentBD.toString();
}
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
TextView spPrice = (TextView) view.findViewById(R.id.sp_price);
spPrice.setText(spPriceS);
TextView spPercent = (TextView) view.findViewById(R.id.sp_percent);
spPercent.setText(spPercentS);
TextView nasdaqPrice = (TextView) view.findViewById(R.id.nasdaq_price);
nasdaqPrice.setText(nasdaqPriceS);
TextView nasdaqPercent = (TextView) view.findViewById(R.id.nasdaq_percent);
nasdaqPercent.setText(nasdaqPercentS);
}
}
这是我的logcat输出：
