Android java.lang.ArrayIndexOutOfBoundsException: 长度=10;指数=10

Question

我很难弄清楚这一点。我无法在我的手机上重现（nexus 4）。似乎不会影响所有设备，但我有足够多的报告看到它不断发生令人沮丧。

Answer 1

Array 索引从 0 开始并在 array length 减去 1..所以将循环限制为 9。

Answer 2

需要设置属性android:lines="1" android:singleLine="true" https://code.google.com/p/android/issues/detail?id=33868

Answer 3

他们至少应该将这个添加到 Lint 中！ :S 您可以使用自定义文本视图来解决此问题。

public class MyTextView extends TextView {
    public MyTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    public MyTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public MyTextView(Context context) {
        super(context);
        init();
    }

    private void init() {

        // this is to overcome the calculateEllipsis bug in some versions of android, I spotted it on 4.4.4 and 4.4.3
        // see https://code.google.com/p/android/issues/detail?id=33868

        if (Build.VERSION.SDK_INT >= 16) {
            if (getMaxLines() == 1) {
                setSingleLine(true);
            }
        }
    }
}

在你的 xml 中引用 MyTextView 而不是普通的 textview。

Answer 4

这是一个错误。在android本身报告请忽略使用start。 https://code.google.com/p/android/issues/detail?id=33868

Answer 5

把 for 循环改成这样

你的数组长度 0 到 10

for (int i=0; i<9; i++)
{
      System.out.println("value is  ofposition"+yourArrayList[i]);
}

Answer 6

问题

1. 如果我们设置android:maxLines="1" android:ellipsize="middle"，那么我们的应用程序会在某些设备中崩溃。

解决方案

1. Android 文档说，当我们设置 "android:maxLines" 属性时，"android:ellipsize" 属性仅支持 End 和 Marquee。

参考

setEllipsize

在 API 级别 1 中添加

void setEllipsize (TextUtils.TruncateAt where)

使文本中长于视图宽度的单词被椭圆化而不是在中间断开。您可能还需要 setSingleLine() 或 setHorizo​​ntallyScrolling(boolean) 将文本限制为单行。使用 null 关闭省略号。 如果已使用 setMaxLines(int) 设置两行或多行，则仅支持 END 和 MARQUEE（其他省略号类型不会做任何事情）。
