Android eclipse：不幸的是，ProjectThing已經停止，錯誤

-1

當我剛接觸android並且最近創建了一些簡單的應用程序時，我決定做一個快照遊戲，但是當我嘗試運行它在AVD上時，我得到這個錯誤：Unfortunately ProjectThing has stopped。Android eclipse：不幸的是，ProjectThing已經停止，錯誤

主要代碼：

`package com.example.snapgame; 

import java.util.Random; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.View; 
import android.widget.Button; 
import android.widget.TextView; 

public class MainActivity extends Activity { 
    public TextView t1, t2, t3; 
    public Button b1; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     t1 = (TextView) findViewById(R.id.textView1); 
     t2 = (TextView) findViewById(R.id.textView2); 
     t3 = (TextView) findViewById(R.id.textView3); 
     b1 = (Button) findViewById(R.id.button1); 

     Snap(); 

     b1.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       int score = 0; 
       if(t1.equals(t2)){ 
        score++; 
        t3.setText(score); 
       } 

      } 
     });{ 

     } 
    } 

     private void Snap() { 

      String aWords1[] = {"Red", "Blue", "Green", "Yellow"}; 
      String aWords2[] = {"Red", "Blue", "Green", "Yellow"}; 
      String randomColor1 = (aWords1[new Random().nextInt()]); 
      String randomColor2 = (aWords2[new Random().nextInt()]); 

      t1.setText(randomColor1); 
      t2.setText(randomColor2); 

     } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

}`

主要layout.XML：

</RelativeLayout>`

的Android的Manifest.xml：

<?xml version="1.0" encoding="utf-8"?>

不幸的是，StackOverflow並沒有被設計成學習人們閱讀StackTrace的地方。 –

首先什麼是ArrayIndexOutOfBoundsException？

拋出以指示已使用非法索引訪問數組。該索引或者是負值，或者大於或等於該陣列的大小。

如果你檢查你的logcat你會看到它拋出這個異常的行：

at com.example.snapgame.MainActivity.Snap(MainActivity.java:47)

所以你要看看你的MainActivity的java文件的第47行。

如何解決這個問題？

它在這裏：

String randomColor1 = (aWords1[new Random().nextInt()]); 
String randomColor2 = (aWords2[new Random().nextInt()]);

應該

String randomColor1 = (aWords1[new Random().nextInt(aWords1.length)]); 
String randomColor2 = (aWords2[new Random().nextInt(aWords2.length)]);

爲什麼？

因爲nextInt()返回僞隨機均勻分佈int。或者int的可能值在-2^31和2^31-1之間。

或者您的陣列可能的索引從0到yourArray.length - 1。

由於兩個數組的長度是從0到3，你的情況，你會拋出此異常時nextInt()返回比0低於或高於3優越的整數。

幸運的是，API爲您提供了一種方法！

你必須使用重載方法nextInt(int n)它返回一個僞隨機均勻地分佈在半開區間[0, n)int（裝置0包括和n 不包括在內）。
