Android: set color programatically from XML color constants
提问by prototype0815
Trying to set a color which is defined in res/values/colors.xml to an object,
尝试将 res/values/colors.xml 中定义的颜色设置为对象，
<?xml version="1.0" encoding="utf-8"?>
<resources>
<drawable name="listViewSelected">@android:color/holo_blue_light</drawable>
<drawable name="listViewPressed">@android:color/holo_green_light</drawable>
<drawable name="pagerTabStrip">#2B3333</drawable>
<!--<drawable name="pagerTabStrip">#353F3E</drawable>-->
<drawable name="tableHead">#FF444444</drawable>
</resources>
I can not figure out why it is not working,
I tried a lot of approaches (getResources(), Color.parseColor(), ...)
我不知道为什么它不起作用，我尝试了很多方法 (getResources(), Color.parseColor(), ...)

Get a handle to the root layout used, then set the background color on that. The root layout is whatever you called setContentView with.
获取使用的根布局的句柄，然后在其上设置背景颜色。根布局是您使用 setContentView 调用的任何内容。
// Now get a handle to any View contained // within the main layout you are using
// 现在获取包含在您正在使用的主布局中的任何视图的句柄 //
View someView = findViewById(R.id.randomViewInMainLayout);
// Find the root view
// 找到根视图
View root = someView.getRootView()
// Set the color
// 设置颜色
root.setBackgroundColor(getResources().getColor(android.R.color.red));
