推荐答案

您可以通过编程方式做到这一点，甚至改变颜色，只要你想，通过遵循的链接的问题你提到，再加上加入的 Col​​orFilter 来调整颜色。

You can do this programmatically, even change the color as you want, by following the solution in the linked question you mention, plus adding a ColorFilter to adjust the color.

所以：

1. 创建相应的绘制。最简单的方法，如在答案之一提到的，使用 https://jgilfelt.github.io/ Android的actionbarstylegenerator /


2. 将到项目的 tab_indicator_ab_example.xml （以绘）加上6相关PNG文件（制表_ *。PNG）每次绘制密度。


3. 创建选项卡后，使用code，它在 TabWidget 子视图迭代来设置他们的背景，但是：


4. 而不是设置绘制原样，的使用滤色镜，以改变其颜色为所需的单的的。

1. Create the appropriate drawable. The easiest way, as mentioned in one of the answers, is using https://jgilfelt.github.io/android-actionbarstylegenerator/
2. Place into your project the tab_indicator_ab_example.xml (in drawable) plus the 6 associated png files (tab_*.png) for each drawable density.
3. After creating the tabs, use the code that iterates over the TabWidget child views to set their background, however:
4. Instead of setting the drawable as-is, use a color filter to change its color to the desired one.

相反这code的：

for(int i = 0; i < widget.getChildCount(); i++) {
    ... /* same as before */

    v.setBackgroundResource(R.drawable.your_tab_selector_drawable);
}

这样写：

for(int i = 0; i < widget.getChildCount(); i++) {
    ... /* same as before */

    Drawable d = getResources().getDrawable(R.drawable.tab_indicator_ab_example);
    d.setColorFilter(Color.GREEN, PorterDuff.Mode.SRC_IN);
    v.setBackgroundDrawable(d);
}
