有没有办法在不使用状态列表的情况下以编程方式设置特定的 Tablayout.Tab 文本颜色? [英] Is there a way to set a particular Tablayout.Tab text color programmatically, without using a state list?

问题描述

问题是如何更改单个 TabLayout.Tab 的文本颜色.理想情况下，我想遍历选项卡并根据相应 ViewPager 的片段中包含的信息更改它们的颜色.

The question is how to change a single TabLayout.Tab's text color. Ideally, I'd like to iterate over the tabs and change their color based on information contained on the fragment of a corresponding ViewPager.

推荐答案

最简单的方法是从指定的TabLayout.Tab中获取TextView，然后设置文本颜色使用TextView.SetTextColor(Color color)，你可以这样做:

The easiest way is to get the TextView from a specified TabLayout.Tab and then set the text color using TextView.SetTextColor(Color color), which you can do as followed:

TabLayout tabLayout = new TabLayout(this);
int wantedTabIndex = 0;

TextView tabTextView = (TextView)(((LinearLayout)((LinearLayout)tabLayout.GetChildAt(0)).GetChildAt(wantedTabIndex)).GetChildAt(1));

var textColor = Color.Black;
tabTextView.SetTextColor(textColor);
