Question

请帮我分一下这样的字符串＆＃34; mumbai（或）pune＆＃34;使用java。

我希望＆＃34;）＆＃34;之后的字符串，我尝试使用String result="pune".但不使用上面的字符串格式。

我的预期输出是＆＃34; pune＆＃34;。

输入：

public class MyCanvas extends View {
     private int total;
     private int width;
     private int height;

     @Override
     public void onDraw(Canvas canvas){
        // Drawing my stuff here with (width and height gives me 0 here)
        if(total == 50 || total == 150){ total == 100;}
    }
     public int addToCanvas(int value){ total += value ;}
     public int subtractToCanvas(int value){ total -= value ;}

     //All three of contructors here
     public MyCanvas(Context context) {
       super(context);
       total = 100;
       width = getWidth();
       height = getHeight();
     }

     public MyCanvas(Context context, AttributeSet attrs) {
        super(context, attrs);
        total = 100;
        width = getWidth();
        height = getHeight();
     }

    public MyCanvas(Context context, AttributeSet attrs, int defStyleAttr) {
       super(context, attrs, defStyleAttr);
       total = 100;
       width = getWidth();
       height = getHeight();
    }
}

输出：

public class MainActivity extends Activity {

    private MyCanvas mycanvas;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mycanvas= (MyCanvas) findViewById(R.id.customcanvas);
        mycanvas.addToCanvas(10);
    }
}

Answer 1

如果您的输入字符串始终与您显示的字符串相似：

yourString.split("\\)")[1].trim();

Answer 2

您可以将其拆分为多个部分：

String abc="mumbai (or) pune"
String result = "pune";

String[] parts = abc.split(" ");
String partOne = parts[0];
String partTwo = parts[2];

if (partOne == result){
   System.out.println(partOne);
}
else{
   System.out.println(partTwo);
}

Answer 3

试试这个：

String s = "mumbai (or) pune";
String result = s.substring(s.lastIndexOf(')') + 1).trim();

Answer 4

替换在这里实际上会更有效率。

使用：

 String abc="mumbai (or) pune";
 abc = abc.replaceAll(".*\\s+(\\w+)","$1");
 // abc will be "pune" here

Answer 5

有很多方法可以做你想要的简单事情。最佳方法：阅读Java中的字符串操作

以下是实现您所需要的一些方法：

 public static void main(String[] args)
{
    String output1 = "mumbai (or) pune";
    String output2 = output1.split("or\\) ")[1];
    String output3 = output1.substring(output1.indexOf(")")+2);;        

    System.out.println(output1);
    System.out.println(output2);
    System.out.println(output3);        
}
