Question

我想在textview中显示html内容，如果超过5行，则修剪其他行并添加＆＃34; ...＆＃34;在末尾。我使用这些代码来添加修剪附加行

textview.setText(Html.fromHtml(message));

this.setAutoLinkMask(Linkify.ALL);
this.setMaxLines(5);
this.setEllipsize(TextUtils.TruncateAt.END);
this.setHorizontalScrollBarEnabled(true);

但它仅适用于某些文本，

        ViewTreeObserver vto = feedListRowHolder.description.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {

            @Override
            public void onGlobalLayout() {
                ViewTreeObserver obs = feedListRowHolder.description.getViewTreeObserver();
                if (Build.VERSION.SDK_INT < 16) obs.removeGlobalOnLayoutListener(this);
                else obs.removeOnGlobalLayoutListener(this);

                if (feedListRowHolder.description.getLineCount() > 5) {
                    int lineEndIndex = feedListRowHolder.description.getLayout().getLineEnd(4);
                    String text = textview.subSequence(0, lineEndIndex - 3) + "...";
                    textview.setText(Html.fromHtml(text));
                }
            }
        });

问题是它从文本中删除了html格式。

Answer 1

更改此String text = textview.subSequence(0, lineEndIndex - 3) + "...";

到String text = message.subSequence(0, lineEndIndex - 3) + "...";

Android textview ellipse删除了html内容
