不仅是空白，我的解决方案也解决了看不见的字符。

str = "Hello I'm your String";
String[] splited = str.split("\p{Z}");

试试这个

    String str = "This is String";
    String[] splited = str.split("\\s+");

    String split_one=splited[0];
    String split_second=splited[1];
    String split_three=splited[2];

   Log.d("Splited String ", "Splited String" + split_one+split_second+split_three);

这里有一个方法来修剪有“，”或空白的字符串

private String shorterName(String s){
        String[] sArr = s.split("\\,|\\s+");
        String output = sArr[0];

        return output;
    }

简单的吐串由空间

    String CurrentString = "First Second Last";
    String[] separated = CurrentString.split(" ");

    for (int i = 0; i < separated.length; i++) {

         if (i == 0) {
             Log.d("FName ** ", "" + separated[0].trim() + "\n ");
         } else if (i == 1) {
             Log.d("MName ** ", "" + separated[1].trim() + "\n ");
         } else if (i == 2) {
             Log.d("LName ** ", "" + separated[2].trim());
         }
     }

不仅是空白，我的解决方案也解决了看不见的字符。

str = "Hello I'm your String";
String[] splited = str.split("\p{Z}");

Try

String[] splited = str.split("\\s");
