问题描述

我如何选择选项卡的字样大胆SlidingTabLayout？我发现设置所选标签颜色不够的问题，但在设置所选标签字样没有。先谢谢了。

How do I make selected tab's Typeface bold in SlidingTabLayout? I found enough questions on setting the selected tab colour, but none on setting the selected tab Typeface. Thanks in advance.

推荐答案

我终于成功，如下所示：

I finally managed it as follows:

在 onPageScrolled（）方法进行以下更改：

View selectedTitle = mTabStrip.getChildAt(position);
        View leftOfSelected = mTabStrip.getChildAt(position-1);
        View rightOfSelected=null;
        if (position<=tabStripChildCount-1) {
            rightOfSelected = mTabStrip.getChildAt(position + 1);
        }

        if (selectedTitle != null) {
            TextView selectedText = (TextView) selectedTitle;
            TextView leftOfSelectedText = (TextView) leftOfSelected;
            TextView rightOfSelectedText = (TextView) rightOfSelected;
            if (position > 0 && position < tabStripChildCount - 1) {
                selectedText.setTypeface(Typeface.DEFAULT_BOLD);
                leftOfSelectedText.setTypeface(Typeface.DEFAULT);
                rightOfSelectedText.setTypeface(Typeface.DEFAULT);
            } else if (position == 0) {
                selectedText.setTypeface(Typeface.DEFAULT_BOLD);
                rightOfSelectedText.setTypeface(Typeface.DEFAULT);

            } else if (position == tabStripChildCount - 1) {
                selectedText.setTypeface(Typeface.DEFAULT_BOLD);
                leftOfSelectedText.setTypeface(Typeface.DEFAULT);
            }
        }

同样， scrollToTab（）方法可以使用​​相同的code片段如上编辑。所有你需要做的是替换 selectedTitle 与 selectedChild 和位置与的tabIndex 。如果你想更好的UI响应，你也可以做同样的使用onPageSelected（）方法。不过，别忘了重新声明 tabStripChildCount 。

Similarly, the scrollToTab() method can be edited with the same code snippet as above. All you need to do is replace selectedTitle with selectedChild and position with tabIndex. If you want better UI response, you may also do the same in onPageSelected() method. Just remember to re-declare tabStripChildCount.

干杯！
