共有設定に保存されている一連の変数 (float/integer/string) があります。初めて実行すると、3 つのデータすべてが完全に表示されます。2 回目に実行すると、debtNames1 が保持されますが (以下を参照)、amount1 は 0.0 になります。私はスクリプトを調べて、長い/文字列を試してみましたが、同じことをします。以下は活動です：
public class DebtList extends Activity {
String debtNames1, debtNames2, debtNames3, debtNames4, debtNames5, debtNames6 = null;
float amount1, amount2, amount3, amount4, amount5, amount6;
long debtRate1, debtRate2, debtRate3, debtRate4, debtRate5, debtRate6;
int debtTerm1, debtTerm2, debtTerm3, debtTerm4, debtTerm5, debtTerm6;

SharedPreferences.Editor editor= sharedPref.edit();
editor.putString("debtNames1", debtNames1);
editor.putFloat("debtAmount2", amount1);
editor.putLong("debtRate1", debtRate1);
editor.putInt("debtTerm1", debtTerm1);
editor.putString("debtNames2", debtNames2);
editor.putFloat("debtAmount2", amount2);
editor.putLong("debtRate2", debtRate2);
editor.putInt("debtTerm2", debtTerm2);
editor.putString("debtNames3", debtNames3);
editor.putFloat("debtAmount2", amount3);
editor.putLong("debtRate3", debtRate3);
editor.putInt("debtTerm3", debtTerm3);
editor.putString("debtNames4", debtNames4);
editor.putFloat("debtAmount2", amount4);
editor.putLong("debtRate4", debtRate4);
editor.putInt("debtTerm4", debtTerm4);
editor.putString("debtNames5", debtNames5);
editor.putFloat("debtAmount2", amount5);
editor.putLong("debtRate5", debtRate5);
editor.putInt("debtTerm5", debtTerm5);
editor.commit();
}
前述したように、データを「取得」すると、最初の if で完全に表示されます。2 回目にデータを「取得」すると、2 回目の if では完全に表示されますが、1 回目の if では amount1 ではなく、debtNames1 のみが正しく表示されます。
何か案は？
ありがとう！
