目前看来有三种方法可以实现

1. framelayout, a framelayout is used to stack a TextView on top of an ImageView

Java代码   ​​

​​

1. <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
2. "fill_parent"
3. "fill_parent">
4. 
5. <ImageView
6. "fill_parent"
7. "fill_parent"
8. 
9. "center"
10. "@drawable/golden_gate"
11. 
12. <TextView
13. "wrap_content"
14. "wrap_content"
15. "20dip"
16. "center_horizontal|bottom"
17. 
18. "12dip"
19. 
20. "#AA000000"
21. "#ffffffff"
22. 
23. "Golden Gate"
24. 
25. </FrameLayout>

 

2. TextView on Canvas。 和framelayout不同，Canvas不是继承自ViewGroup，它不可以添加child views，所以你需要使用drawBitmap和drawText方法去实现

 

3. 使用merge tag，方法大致和framelayout一样

Java代码   ​​

​​

1. <?xml version="1.0" encoding="utf-8"?>
2. <!--<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3. "vertical"
4. "fill_parent"
5. "fill_parent"
6. >
7. --><merge xmlns:android="http://schemas.android.com/apk/res/android">
8. 
9. <ImageView
10. "fill_parent"
11. "fill_parent"
12. 
13. "center"
14. "@drawable/mini"
15. 
16. <TextView
17. "wrap_content"
18. "wrap_content"
19. "center"
20. "12dip"
21. "20sp"
22. "bold"
23. "#ffff0000"
24. 
25. "Mini-Countryman"
26. 
27. </merge>
28. <!--</LinearLayout>
29. -->
