java - Android:拆分功能不起作用

Question

我在代码中收到强制关闭消息。有人可以向我解释一下为什么我会收到这个结果吗？

package com.example.splitfunction;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class SplitFunction extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TextView tv = new TextView(this);
        String url = "http://mysub.somedomain.com/tabletcms/tablets/youcontent/000002/thumbnails/110/png";
        String[] values;
        int x = 0;

        tv.setText("SPLIT FUNCTION PROGRAM...\n");
        tv.append(url);

        values = url.split("/");

        while( x < values.length ){
            tv.append("\n" + x + ":> " + values[x]);
            x++;
        }

        setContentView(tv);
    }
}

你需要增加x，否则它是一个无限循环:

tv.append("\n" + x + ":> " + values[x++]);

或

    while( x < values.length ){
        tv.append("\n" + x + ":> " + values[x]);
        x++
    }
