獲取元素從字符串數組

Question

我想從字符串數組中的元素在Android和我的字符串數組是：

String[] arrayID = {"3740","3491","3661","3838"}; 

Answer 1

可以通過索引獲得元素...

arrayID[0]會給你3740等等...

或者可以遍歷並獲得要素...

for(int i = 0; i < arrayID.length - 1; i++) { 
    System.out.println(i+" = "+arrayID[i]); 
} 

輸出
0 = 3740
1 = 3491
2 = 3661
3 = 3838

Answer 2

String myID = arrayID[0]訪問的第一要素。將0替換爲其他索引編號以訪問連續項目。

這樣：

String myFirstID = arrayID[0] //returns "3740" 
String mySecondID = arrayID[1] //returns "3491" 
String myThirdID = arrayID[2] //returns "3661" 
String myFourthID = arrayID[3] //returns "3838" 

Answer 3

嘗試這種情況：通過指定元素的索引

String[] arrayID = {"3740","3491","3661","3838"}; 

可以從陣列獲取元件

其中第一元素索引

3740是0，

3491是1等

arrayId[index]
