Android TextView 给出 IndexOutOfBoundsException TextLine.handleRun

Question

不久前我收到了这个异常，我从堆栈跟踪中找不到任何有用的东西，Crashlytics 报告它发生在 Android 8 和 9 上

这是堆栈跟踪:

所以堆栈跟踪没有为我提供 TextView正在发生我正在记录崩溃发生的屏幕，这个屏幕有很多 TextView我搜索了整个网络，但找不到答案。

更新

我怀疑这段代码会为 TextView 中的电话号码绘制圆形背景。

public class RoundedBackgroundSpan extends ReplacementSpan implements LineHeightSpan {

    private static int CORNER_RADIUS = 8;
    private int backgroundColor = 0;
    private int textColor = 0;
    private int backgroundTranspernt;
    private float mTextSize = UIUtils.spToPx(16);

    private static final float PADDING_X = UIUtils.dp2px(4);
    private static final float PADDING_Y = UIUtils.dp2px(2);
    private static final float MAGIC_NUMBER = UIUtils.dp2px(2);

    public RoundedBackgroundSpan(Context context) {
        super();
        backgroundColor = context.getResources().getColor(R.color.NavigationBarStrokeColor);
        textColor = context.getResources().getColor(R.color.white);
        backgroundTranspernt = context.getResources().getColor(R.color.transparent);
    }

    public RoundedBackgroundSpan(Context context, @ColorRes int textColor,
                                 @ColorRes int backgroundColor) {
        super();
        this.backgroundColor = context.getResources().getColor(backgroundColor);
        this.textColor = context.getResources().getColor(textColor);
        backgroundTranspernt = context.getResources().getColor(backgroundColor);
    }

    @Override
    public void draw(Canvas canvas, CharSequence text, int start, int end, float x, int top, int
            y, int bottom, Paint paint) {


        paint = new Paint(paint); // make a copy for not editing the referenced paint

        paint.setTextSize(mTextSize);

        // Draw the rounded background
        paint.setColor(backgroundColor);
        float textHeightWrapping = UIUtils.dp2px(0);
        float tagBottom =
                top + textHeightWrapping + PADDING_Y + mTextSize + PADDING_Y + textHeightWrapping;
        float tagRight = x + getTagWidth(text, start, end, paint);
        RectF rect = new RectF(x, top, tagRight, tagBottom);
        canvas.drawRoundRect(rect, CORNER_RADIUS, CORNER_RADIUS, paint);

        // Draw the text
        paint.setColor(textColor);
        canvas.drawText(text, start, end, x + PADDING_X,
                tagBottom - PADDING_Y - textHeightWrapping - MAGIC_NUMBER, paint);

    }

    @Override
    public int getSize(Paint paint, CharSequence text, int start, int end, Paint.FontMetricsInt
            fm) {
        paint = new Paint(paint); // make a copy for not editing the referenced paint
        paint.setTextSize(mTextSize);
        return getTagWidth(text, start, end, paint);
    }

    private int getTagWidth(CharSequence text, int start, int end, Paint paint) {
        return Math.round(PADDING_X + paint.measureText(text.subSequence(start, end).toString()) + PADDING_X);
    }

    @Override
    public void chooseHeight(CharSequence text, int start, int end, int i2, int i3,
                             Paint.FontMetricsInt fontMetricsInt) {
        //we need to implement this so the text know the  line height
    }
}

它会屏蔽手机，使其可通过 clickSpan 进行点击

此错误与添加到 TextView 的文本有关。 .您所指的圆形背景不相关，因为该错误专门与文本有关，与 TextView 的任何其他方面无关.

如果 TextView从主线程以外的线程操作。确保任何接触 UI 小部件的代码仅在主线程上执行。如果您使用 RxJava，请确保您已正确使用 observeOn(AndroidSchedulers.mainThread()在必要时。
