Java onclick时应用程序崩溃

当我点击

numbercontent

侦听器打开我的

NumbersActivity

类文件时，我的android应用程序崩溃

我使用在

NumbersActivity

类文件上设置的arraylist名称“word”，使用

while

循环分配字符串列表

除了

NumbersActivity

类文件之外，其他类似乎都很好。我不明白为什么，有人能帮忙吗

下面是java文件

                startActivity(colorsIntent);
            }

        TextView phrases = (TextView) findViewById(R.id.phrases);

        // Set a click listener on that View
        phrases.setOnClickListener(new OnClickListener() {
            // The code in this method will be executed when the phrases category is clicked on.
            @Override
            public void onClick(View view) {
                // Create a new intent to open the {@link PhrasesActivity}
                Intent phrasesIntent = new Intent(MainActivity.this, PhrasesActivity.class);

                // Start the new activity
                startActivity(phrasesIntent);
            }
        });

protected void onCreate(Bundle savedInstanceState) {

        View view = getLayoutInflater().inflate(R.layout.activity_numbers, null);
        setContentView(view);

        ArrayList<String> words =  new ArrayList<String>();
        words.add("One");
        words.add("Two");

            TextView wordView = new TextView(this);

而（索引

在数字活动中，您有以下代码行：

while (index < words.size());

while（索引

尝试删除运算符末尾的“”；“”，应如下所示：

while (index < words.size())

while（索引

发布logcat错误拼写错误是不可能的，除非在相同或不同的布局中有具有该ID的视图。如果布局名称为

活动编号

，写入

活动编号

将在IDE（和块编译）中显示错误，因为它知道它不存在。如果布局确实存在，它将膨胀一个不同于预期的布局，但如果它不尝试检索不存在的视图，它仍将运行。我已经添加了我的xml文件，您认为问题是否来自xml部分？这是主xml，应用程序在打开活动时崩溃。据我所知，JAVA代码中没有明显的错误。数字XML中可能有一些错误是的，我在这里添加了数字XML，将您的代码替换为已编辑的应答中的代码谢谢正在工作！
