Android如何根据背景图片更改文本颜色
问题描述：
在Android上，我有一个带有背景图片的标题(根据API的随机图片).在此标题上，我有一些数据文本.我的文字每次都是黑色的，但有时图像也是黑色的.因此，我们看不到文字.
On Android, I have a header with a background image (Random image according to API). On this header I have texts with some data. My text is every time black but sometimes image is black too. So, we can't see the text.
