如何调用 public void(int i,string s)

Question

我有 main activity，它包含 public void(string,int) 和 main activity 中的一些地方，我想调用 public void 但是我得到错误 'void checkout(string,int) cannot be applied to ()'...

我就是这样称呼我的 public void:

main activity {
//some where in main activity 

checkout();  //here i call public void but this line show error

public void checkout(String answer,int missedcallcount){

String MissedCallWhere = CallLog.Calls.TYPE + "=" + CallLog.Calls.MISSED_TYPE + " AND " + CallLog.Calls.NEW + "=1";

Cursor cmissedcallc = getApplicationContext().getContentResolver().query(CallLog.Calls.CONTENT_URI,null,MissedCallWhere, null, null);
cmissedcallc.moveToFirst();
Log.d("CALL", ""+cmissedcallc.getCount()); 
missedcallcount = cmissedcallc.getCount();
cmissedcallc.close();


if (missedcallcount<=5){
     answer= "you have less than 5 miss call";
 }else if (missedcallcount>5){
     answer= "you have more than 5 miss call";
 }

}
}

请帮助我...谢谢

Answer 1

checkout();  //here i call public void but this line show error

您应该在构造函数中调用参数，在这种情况下代码应如下所示：

checkout(answer, missedCallCount);

Answer 2

public void checkout(String answer,int missedcallcount)

此方法的声明表明，您需要传递两个参数才能正确调用它 - 在本例中，如果您想调用此方法，您需要将 String 作为第一个参数传递给它，和 int 作为第二个参数。下面是正确调用该方法的例子：

checkout("Abcdef", 12345);
