Android 未收到意图

我有两个活动涉及这个问题。第一种是用户在一个简单的表单样式布局上输入数据。然后，它应该将这4条数据保存到intent（putextra）和startActivity（intent）中

第二个应该检索数据并准备好将它们加载到数组中。当我运行调试时，activity1的意图成功地保存了这些值；然而，activity2表示意图为空。。我不确定其间发生了什么

活动1

EditText editDebtName = (EditText) findViewById(R.id.dispDebtName);
    debtName = editDebtName.getText().toString();

    EditText editDebtAmount = (EditText) findViewById(R.id.dispDebtAmount);
    String debtAmountStr = editDebtAmount.getText().toString();

    EditText editDebtRate = (EditText) findViewById(R.id.dispDebtRate);
    String debtRateStr = editDebtRate.getText().toString();

    EditText editDebtPayment = (EditText) findViewById(R.id.dispDebtPayment);
    String debtPaymentStr = editDebtPayment.getText().toString();

    Intent i = new Intent(this, DebtList.class);
    i.putExtra("newDebtName", debtName);
    i.putExtra("newDebtAmount", debtAmountStr);
    i.putExtra("newDebtRate", debtRateStr);
    i.putExtra("newDebtPayment", debtPaymentStr);

    startActivity(i);

活动2

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.debtlist);

    String[] debtName = new String[10];
    String[] debtAmount = new String[10];
    String[] debtRate = new String[10];
    String[] debtPayment = new String[10];
    int trigger = 5;

    SharedPreferences sharedPref= getSharedPreferences("chaosdatasnowball", 0);

    debtName = getFromSharedPreference("debtNames", this.getApplicationContext());
    debtAmount = getFromSharedPreference("debtAmounts", this.getApplicationContext());
    debtRate = getFromSharedPreference("debtRates", this.getApplicationContext());
    debtPayment = getFromSharedPreference("debtPayments", this.getApplicationContext());

    trigger = sharedPref.getInt("trigger", trigger);

    Bundle extras = getIntent().getExtras();
    debtName[trigger] = extras.getString("newDebtName");
    debtAmount[trigger] = extras.getString("newDebtAmount");
    debtRate[trigger] = extras.getString("newDebtRate");
    debtPayment[trigger] = extras.getString("newDebtPayment");

也不会抛出任何错误消息。我想确定的是。。为什么我的意图没有被接收？

我认为这个问题是由这个代码引起的

    SharedPreferences sharedPref= getSharedPreferences("chaosdatasnowball", 0);
    debtName = getFromSharedPreference("debtNames", this.getApplicationContext());
    debtAmount = getFromSharedPreference("debtAmounts", this.getApplicationContext());
    debtRate = getFromSharedPreference("debtRates", this.getApplicationContext());
    debtPayment = getFromSharedPreference("debtPayments", this.getApplicationContext());

因为我在没有上面代码的情况下进行测试，activity2仍然会收到bundle值。如果您在没有上述代码的情况下尝试，但仍然存在该问题，则应尝试调试并显示字符串数组的所有值，以再次确定问题。

意图为空，还是附加值？
