我有我的应用程序，以便用户输入日期（yyyy/MM/dd），如果该人想要将事件添加到他们的日历中，则可以使用复选框。这是用于贷款支付（假设每月），所以我希望它检查要标记的框：
if(addCalander.isChecked())
声明是：
CheckBox addCalander = (CheckBox) findViewById(R.id.checkBox1);
一旦用户点击布局底部的“提交”框，我希望活动从不同字段收集数据，验证复选框（上方）并假设它已被选中，将每月重复事件添加到日历中贷款的基本期限（我稍后会编程，但让我们假设：
int debtTerm = 60; //60 months
以下是我的完整 .java::
public void ButtonOnClick(View v)
{
switch (v.getId()) {
case R.id.buttonSubmit:
TextView textDebtName = (TextView) findViewById(R.id.textDebtName);
String debtName = textDebtName.getText().toString();
TextView textDebtAmount = (TextView) findViewById(R.id.textDebtAmount);
TextView textDebtRate = (TextView) findViewById(R.id.textDebtRate);
TextView textDebtPayment = (TextView) findViewById(R.id.textDebtPayment);
TextView textDebtDate = (TextView) findViewById(R.id.textDebtDate);
EditText editDebtName = (EditText) findViewById(R.id.dispDebtName);
EditText editDebtAmount = (EditText) findViewById(R.id.dispDebtAmount);
EditText editDebtRate = (EditText) findViewById(R.id.dispDebtRate);
EditText editDebtPayment = (EditText) findViewById(R.id.dispDebtPayment);
EditText editDebtDate = (EditText) findViewById(R.id.dispDebtDate);
CheckBox addCalander = (CheckBox) findViewById(R.id.checkBox1);
String CalanderStr = addCalander.getText().toString();
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd");
try {
Date startDate = dateFormat.parse("string");
} catch (ParseException e) {
e.printStackTrace();
}
if(addCalander.isChecked())
{
Uri eventsUri;
if (android.os.Build.VERSION.SDK_INT <= 7) {
eventsUri = Uri.parse("content://calendar/events");
} else {
eventsUri = Uri.parse("content://com.android.calendar/events");
}
Calendar cal = Calendar.getInstance();
ContentValues event = new ContentValues();
event.put("calendar_id", 1);
event.put("title", debtName);
event.put("description", "Loan Payment Due");
event.put("eventLocation", "My Lender");
event.put("dtstart",CalanderStr);
event.put("rrule", "FREQ=MONTHLY;WKST=SU;BYDAY=SA");
event.put("allDay", 1); // 0 for false, 1 for true
event.put("eventStatus", 1);
event.put("hasAlarm", 1); // 0 for false, 1 for true
event.put("duration","P90000S");
Uri url = getContentResolver().insert(eventsUri, event);
}
break;
}
}
当我在我的安卓手机上使用它作为模拟器时，它什么也没做。没有错误，但也没有添加任何内容。我可以整天按提交，但它只是坐着。
请协助！
谢谢！
我在按钮上添加了一个 OnClick，它至少可以读取脚本。下面是我现在收到的错误的 LogCat：
