Android屏幕分辨率不匹配

kerne1

当将Android移植到不同分辨率的产品上，如果不作修改，大多情况下可以正常运行。但是有时候会出现在睡眠唤醒后，锁屏的界面与新的液晶屏分辩率不配配的情况。

需要修改的文件是：

frameworks/base/core/java/android/content/res/CompatibilityInfo.java

内容如下：

1. /**
   
2. 
     * CompatibilityInfo class keeps the information about compatibility mode that the application is
   
3. 
     * running under.
   
4. 
     *
   
5. 
     *  {@hide}
   
6. 
     */
   
7. 
    public class CompatibilityInfo {
   
8. 
        private static final boolean DBG = false;
   
9. 
        private static final String TAG = "CompatibilityInfo";
   
10. 
    
    
11. 
         /** default compatibility info object for compatible applications */
    
12. 
         public static final CompatibilityInfo DEFAULT_COMPATIBILITY_INFO = new CompatibilityInfo() {
    
13. 
             @Override
    
14. 
             public void setExpandable(boolean expandable) {
    
15. 
                 throw new UnsupportedOperationException("trying to change default compatibility info");
    
16. 
             }
    
17. 
         };
    
18. 
    
    
19. 
         /**
    
20. 
          * The default width of the screen in portrait mode.
    
21. 
          */
    
22. 
         public static final int DEFAULT_PORTRAIT_WIDTH = 480;
    
23. 
    
    
24. 
         /**
    
25. 
          * The default height of the screen in portrait mode.
    
26. 
          */
    
27. 
         public static final int DEFAULT_PORTRAIT_HEIGHT = 800;
