获取元素从字符串数组

Question

我想从字符串数组中的元素在Android和我的字符串数组是：

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

Answer 1

可以通过索引获得元素...

arrayID[0]会给你3740等等...

或者可以遍历并获得要素...

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

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

Answer 2

String myID = arrayID[0]访问的第一要素。将0替换为其他索引编号以访问连续项目。

这样：

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

尝试这种情况：通过指定元素的索引

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

可以从阵列获取元件

其中第一元素索引

3740是0，

3491是1等

arrayId[index]
